Lee's (Royal Melbourne Institute of Technology, Applied Physics Department, 124 Latrobe Street, Melbourne, Victoria 3000, Australia) program to transfer a CP/M file in drive a: to an ICOM FDOS II disk on drive b:. The program is hardware/software dependent, in that it makes references to the ICOM routines in the 0C000H block of memory. FDOS-CPM.ASM handles the opposite direction transfer The programs are well commented. ---------------- ====> CPMLABEL.BAS is Bill Bolton's (P.O. Box 80, Newport Beach, N.S.W., 2106, AUSTRALIA) program to print disk labels individually or in batches for CP/M User's Group Disks. It is slightly hardware dependent, using a CRT that can clear screen, (but doesn't need random cursor positioning). Has well identified hardware dependent routine for reverse video display of error messages, presently set up to suit ADM-31 or Soroc terminal. Uses 80 x 24 display area but only needs minor message reformatting to suit 64 x 16 display. Batch label printing assumes continuous form fed labels, individual printing can be done on any label. CPMLABEL.BAS is written in MICROSOFT BASIC version 5.1. It is suitable for the compiler. Further documentation is available in CPMLABEL.DOC. This program was supplied courtesy of "80AT Australia". (I believe stands for "80 Application Transfer"). Abstract by Ward Christensen (very easy to do thanks to a very complete CP/MUG submission form by Bill) (hint hint) ---------------- ====> CRCK3.ASM is K.B.Petersen's (W8SDZ) file checksum routine. It is a significant improvement over earlier checksum-only programs, in that it does a full 16 bit CRC, rather than just an 8 bit sum. Also, it handles ambiguous file references. Use the program to keep a list of the CRC of various of your programs and files, then use this later if you question that a file has changed. It is particularly useful for comparing a file you have, with a file someone else has, since you can both just run CRCK against them, then compare checksums. Chances of two checksums being the same, but the files being different, is "remote". The program includes the option of being assembled for 4200H base CP/M systems (Heath, R.S.). The program drops in, and has no hardware or software dependencies. ---------------- ====> DU-8/12.ASM is an early version of Ward Christensen's DU program (CP/M U.G. volume 40), and as such lacks a few of the features of the volume 40 version. It was modified by Keith Petersen W8SDZ, Bruce Ratoff ACGNJ, Jeff Hammersley, and Charles Strom. It would be useful to anyone wanting to work directly with a CP/M disk, such as to patch it. The program is used to dump and patch a CP/M disk directly. Further documentation may be found in the .ASM file. This version supports single density CP/M, and via conditional assembly switches, the following: * Micropolis * Digital Microsystems double density FDC3 controller * Northstar double density * Thinker toys DJ2D controller and 1024 byte sectors * Micromation single-sided double density. This program does direct I/O for the disk thru BIOS. The program is hardware dependent, and may require modification for your system if it is not one of the above. ---------------- ====> DU-V61.ASM by Ward Christensen is his latest version (6.1) of the program distributed as CPMUG file 40.20. Changes: * Now supports Heath 4200 base CP/M * L command (login) rewritten to NOT actually do CP/M login * Track and sector, both as keyed in, and as displayed, are now decimal, not hex. * Q (Quiet option) commmand added - causes functions to not display, so they run faster. * P command fixed to send linefeeds to the printer. See previous abstract for further comments on this program. ---------------- ====> DU/MAP.DOC is a brief explanation of the CP/M directory format as produced by DU.COM. The origin of this document is unknown. I replaced the "XXXX..." type example it used, with a real data example. ---------------- ====> FDOS-CPM.ASM is P.P.H. Lee's program to transfer an ICOM FDOS II file to a CP/M file. See CPM-FDOS.ASM for abstract. ---------------- ====> MDIR8/17.ASM is Jeff Hammersley's program to produce a sorted directory listing, including all "users", for CP/M 2.x. It runs under CP/M 1.4 or 2.x. Note you MUST supply "*.*" to see all files, i.e. you can't just type: mdir The software drops in. It has no software dependencies. ---------------- ====> MLIST3.ASM by Keith Petersen is a program to type a CP/M file, by highly buffering it in memory. This lessens disk activity. Also, for remote access CP/M systems, it doesn't stop "with the first line glitch" like CP/M's TYPE command would. It does respond to ^S and ^C, however. Unlike TYPE, it is able to process ambiguous files (such as *.ASM). There are no hardware dependencies for this program. How- ever, it does require MAC and the SEQIO macro library. ---------------- ====> PLINK823.ASM is L.E. Hughes's program, with the following "mods": L.E. Hughes EDCAM JULY, 1977 (Original) This version by Keith Petersen, W8SDZ. Heath equates added by Tom Jorgenson TRS-80 MODEL 1 mods by Steve Vinokuroff, Vanc CBBS TRS-80 mods by Dennis Breckenridge, Burnaby CBBS This program can send or receive files via modem to such systems as the SOURCE, MICRONET, CBBS, etc. No protocol used. Your computer can act as a computer terminal, with optional capturing of data in memory, and the ability to write it out to disk. A file on disk may also be sent to the remote system, with no protocol. The program operates with any of the following modems: PMMI; ANY serial I/O board (TUART included); TRS-80 model 1; TRS-80 model 2; HEATH H8 with 8251 UART at port 330Q; ---------------- ====> PMMIBYE5.ASM is a remote console program by Dave Jaffe, rewritten for PMMI modem by Ward Christensen, and highly modified since CPMUG volume 40 version, by: Keith Petersen, W8SDZ Dave Hardy Bruce Levison This program allows remote access into CP/M as the console operator, to run any CP/M program. This version of the program may work for people who had trouble with it before, due to added register saves, and larger stack space. Further documentation may be found in PMMIBYE5.DOC The program requires a PMMI modem, and includes options for Morrow's Discus 2D board with memory mapped I/O. Optional- ly, the # of callers may be output to port FF, the front panel of an IMSAI. The program requires as much as 1070 bytes of memory ABOVE your CP/M system. Thus may require generating a smaller CP/M to allow it to fit. The program must be assembled for your particular configuration. ---------------- ====> PTSRCNVT.COM is Tom DiGate's program to convert assembler programs from Processor Technology Package I or ALS-8 format, to CP/M format. The P.T. format file is loaded into memory (by whatever means you have) at 100H, and saved with CP/M SAVE command. PTSRCNVT then converts the file to CP/M format, inserting tabs, and comment semicolons, and deleting the line numbers. Only a .COM file and .DOC file are distributed. ---------------- ====> RETDL.COM is Ward Christensen's RESOURCE.COM from User's Group Volume 42, modified (by person unknown) to disassemble Z80(*) code into TDL mnemonics. See RESOURCE.DOC on volume 42, for operational details. I found this version to not be totally debugged. Some of the more obscure Z80(*) op codes don't work. Some examples: If memory contains: DB 0FDH,0FEH,0FFH it is mis-disassembled as: .BYTE 0FEH when it should be .BYTE 0FDH CPI 0FFH Also, opcodes SPIX (DD F9) and SPIY (FD F9) improperly increment the disassembly PC by 3 bytes, not 2, thus the assembly "loses" a byte for each SPIX or SPIY. I recommend that you reassemble your disassembly and compare it to the original .COM file to catch such errors. Unfortunately, it is not known who the author of this modifi- cation is. Hopefully they will see this and make appropriate changes.This routine came to the Users Group as various names - REZOURCE, or REZ80. Since there will likely some day be versions for both TDL and Zilog, I thought it appropriate to rename this .COM file RETDL, and reserve REZOURCE for the Zilog-format one (which doesn't yet exist; or at least if someone has it, they have not shared it; several people are working on such a version). * Please note that Z80 is a trademark of Zilog, Inc. Use of the term Z80 in this application is in no way meant to infer that this is a program was written by Zilog. ---------------- ====> SURVEY3.ASM is Michael Friese's progam to, as named, "survey" your system. It reports disk, port, and memory utilization. Specifically, it: * Lists Kbytes used and remaining plus number of files on all logged disks (up to 8) * Prints Memory map and synopsis of all machine memory * Lists all active I/O Ports * Uses disk allocation block for all disk calculations Since is tests all ports on the system, be careful it doesn't hang up or cause errors. The .ASM file included conditional assembly instructions for Tarbell, and IMS400 disk controllers, to prevent hanging up. SURVEY3 requires Digital Research's MAC to assemble. The program "drops in" and need be changed only if you have ports which might hang up. It is well commented. ---------------- ====> XD-7/4.ASM is S.J.Singer's extended sorted directory list program, as modified by: H.R.Moran Jr, R.M.Glueck, K.B.Petersen W8SDZ, and John C. Rossmann. It produces a sorted directory listing, across the page, including file sizes. It has no hardware or software dependencies. Included is the ability to be assembled for 4200H base CP/M systems (Heath, R.S.). The code is well commented and quite easy to modify. It would have to be modified for short (e.g. VDM) screens. ---------------- Documentation for PTSRCNVT.COM Written by: Tom Digate Version 1.0 - Nov., 1979 This program is used to convert files that were used with Processor Technology Software Package 1 and ALS8 assemblers to a format that is CP/M assembler compatible. This includes adding tabs and semicolons in place of spaces and asterisks. The program reads the PT file from disk on a byte by byte basis and checks for label,opcode,operand, and comment fields. If a character replacement or deletion is required, it is performed and then the character is written to a new output file. The PT file can be saved on disk by first loading it into memory starting at location 100H and then saving it using the CP/M save command. The command format is as follows: PTSRCNVT ifilename ofilename <cr> The program checks for proper parameters and will abort if any are missing or the input file does not exist. The old ofilename will be erased and then a new file is created. This is done so that you do not have to erase it manually. If a disk error occurs, a message will be printed and the program will abort. This file was assembled using a MACRO library from a previous Users Group Volume and the Digital Research MACro Assembler. The COM file is a ready-to-run version of this file in case you do not have the above software tools. This program will not handle files that do not have line numbers or lines that have only a line number and nothing else. If a label is found, an opcode must be present. Opcodes that have no operand and use a period for formatting purposes will still have the period in the new file. This can be edited out by replacing all occurrences of a <tab>. with a <tab><tab> There are no other known peculiarities of this program. Hope that you enjoy using this program. It has saved me hours in upgrading my cassette system to CP/M. I hope that it can do the same for you. INTERPRETATION OF DIRECTORY DATA PRESENTED BY THE DU PROGRAM The following explains the format of a CP/M directory entry as shown by DU, using either the "F" (find file) command, or just doing "D" (dump) of the directory sectors, which are located in groups 0 and 1 on a single density disk. ---------------- Sample result of "FSID.COM" command: 40 00534944 20202020 20434F4D 0000003A *.SID COM...:* 50 33343536 3738393A 00000000 00000000 *3456789:........* First line - 40 00534944 20202020 20434F4D 0000003A *.SID COM...:* || ||| | || || | | || ||^----hex file name-----^ || || ^file name^ || || || || in ASCII || || extent-^^ || || || || || || file size in sectors-^^ || || || ^^-00 = file active || E5 = file erased ^^-displacement of line in directory sector Second line - 50 33343536 3738393A 00000000 00000000 *3456789:........* | | | | ^---allocation group numbers-------^ 80AT (Series 80 Applications Transfer - Australia) CP/M User's Group Disk Lable Program By Bill Bolton This program is written in Microsoft BASIC release 5.1 and will run under both the compiler and interpreter. As I intended the program to be complied, generous use has been made of long lables which impose no speed penalty with the compiled version. There is a small speed penalty as a result when running with the interpreter but it is minimal. There is extensive operator prompting for all possible program options with defaults set for maximum operator convenience. I suggest that you run the program and see what it does. As presented the program is ready to run on a Lear Seigler ADM 31 or a SOROC terminal. The only hardware dependant features are a clear screen routine (you can simulate it with line feeds) and a reverse video routine (only used to highlight heading and error messages). Both routines are located in the block labled "VIDEO ATTRIBUTES". The program assumes an 80 character wide display, if you have a narrow display you will probably have to change the format of some of the INPUT statement prompts, otherwise the thing should display OK. The program will generate lables for CP/M User's Group disk volumes 1 to 42 (as of June 1980) including 23B. Volume 39 has been withdrawn and no lable can be generated for it, an warning message is displayed if volume 39 is selected. Provsion is made for printing a lable for a "Total Catalogue" disk. A typical lable appears as follows: ******************************************************** * * * CP/M User's Group Disk, Volume : 1 * * * * Various CP/M Utilities * * * * From the 80AT Public Domain Software Library * * * * IBM 3740 Single Density, 128 Byte Sectors * * * ******************************************************** The Density/Bytes per Sector line selection routine is set up for all the formats that 80AT has occasion to use. It is easy to add or delete selections, you simply need to add/delete the selection string and adjust the DIM of SUB$. è The batch print mode assumes that you are using form fed lables. My form fed lables (from Avery) are spaced exactly 9 lines apart from the top of one to the top of the next, so the program assumes this spacing. To change it just insert/delete LPRINT statements in the "PRINT THE LABLE" block as appropriate for your form fed lables. In the individual lable mode you should be able to use just about any type of lable. When further volumes are added to the User's Group collection it will be easy to adjust the program. Just add the new volume numbers and descriptions into the volume check area and change the variable MAX% to the number of the highest volume. The volume numbers are input as strings so it would be possible to add other "extra" volumes such as I have done with "CAT". If you want to do this then just add the new volume "string" to the volume check area and add another option question to the "ALL" routine. The program will take up to 200 entries in one batch, this seemed a reasonable number to me as I rarely do more than two complete sets of lables in one batch. If you really must have more lables in a batch then change the DIM ENTRY$(200) statement at the front of the program to whatever number of entries you want. BE WARNED! If you choose to compile it and exceed the number of entries dimensioned for, unpredicatable (but nasty) things will happen as the variable storage is below the program in the TPA. The interpreter will detect the problem and give you an error message.

Non-commercial use is permitted as an aid for the disemination of knowledge/information but commercial exploitation is not permitted and "I'll come round and rip your bloody arms off" (ancient Australian curse) if I catch you ! PMMIBYE5.DOC (as of 7/20/80) The PMMIBYE5.ASM program is out for distribution, but it has not been thoroughly tested in all of the possible modes of operation. (Please note that version 5.4 is substantially longer than previous PMMIBYE versions. Because of the great number of conditional switches, the program could require as many as 1060 bytes of RAM, or it could be smaller than the 900 bytes used by the original PMMIBYE. It all depends on the way you set it up.) Basically, several new conditional assembly routines have been added to allow user selection at time of assembly of the following: 1. Password access 2. User log (counts number of system callers) 3. Memory-mapped console I/O Also added to V5.4: 1. 710 Baud option for PMMI modem 2. Modifications to AUTO-ANSWER routines 3. "/R" option to allow reset of user log counters Password access was made conditional to allow use with systems that offer unrestricted access. The user log was added to allow the system operators to keep track of the number of people who called the system. In addition, it can also count the number of unsuccessful log-ons (i.e. didn't know password) and the number of voice calls, and conditionally display both numbers on the system console when the program is exited with a control-C from the system console. The counters can be initialized with the "/R" option to all zeroes, or preset by using DDT, or SID. The number of successful log-ons is also conditionally output to port 255 (0FFH) for display on the computer's front panel. The memory-mapped I/O conditionals have been added to allow use of the serial I/O port on the Morrow's 2D controller board as the system console; however, the routines can be used with any memory-mapped system. The 710 Baud option was added for "short-haul" callers, and because operation at 710 Baud with the PMMI modem is "iffy" at best, it will probably be of very little use. The AUTO-ANSWER routines were modified to allow more dependable ringback operation. Unfortuneately, the ringing signal at the caller's end of the phone line does not always correspond exactly with the ringing signal at the system's end. Although a system-end ring does occur sometime during the caller's ring cycle (ring- no ring), it is possible for the system to receive no or 2 rings in the time that the caller thinks just one ring has occurred (The DIAL program is notorious for this). The solution chosen for this problem was to check for one or two rings before call-back. This would allow for the "phase" difference of the caller- system ring signals. This solution also means that the phone must ring at least three times before the system will assume that the call is voice, and is not to be answered. The advantage of this arrangement is that it is virtually impossible for the computer to "miss" a call that is intended for it.
