 Subject: Help with CPTxx

 I am trying to get a copy of either 4.05 or 4.09 Kermit to run on a CPTxx
 system running in data processing mode, and have come up on several problems
 that I need assistance from a user on the network.

 a.  In attempting to download the HEX files, I have hit a roadblock in getting
 the files into the machine.  Would a user out there have a disk containing
 Kermit that I can barter for?  I have no formatted data processing disks at
 present to use to resupply, but would be able to supply a DSDD 3.5 inch disk
 as a replacement.

 b.  Is there a format routine available for this machine that would format a
 disk to use standard DSDD 3.5 inch disks?

 Any assistance would be appreciated

 Sorry, couldn't get e-mail delivered.  This is really directed at the original
 posting.

 I have the pl/i program for cpm, complete with the manual.  Since I'm not using
 cpm any more at all, I'd be glad to sell it.  Either send me e-mail (but please
 be sure I can get back to you--I have only usenet and BITNET access) or snail
 mail.

 Subject: Operating System Command References

 Hello.  I am need of some information for a school project that I am hoping
 everyone may be able to help me with.  What I need to do is make a reference
 chart as large as possible that covers various basic commands for the various
 operating systems in existance. For example:

     Command Summary        UNIX        MS-DOS        TOPS-10

     display directory    ls -l        dir        dir
     copy a file        cp old new    copy old new    copy new old

 What I need from Netland is the common commands for the various operating
 systems.  Such as XENIX, VMS, CP/M, AppleDos, BSD, Xenix, TRS/Ls Dos, etc.
 Just the basic commands.  This also will go into making "alias templates" for
 CSH and KSH for users on UNIX systems who would like to have a command set of
 their native machine.

 Here is a small list of commands that I would like for the chart. It is not all
 of them, just the ones I can think of off hand.  I am using the UNIX
 equivalents
 of each since UNIX is my native operating system.

     cat        cd/chdir    chmod        ln
     lpr        mkdir        more/less    mv
     rm        cp        ls        biff
     finger        who        mail/mailx    mesg
     write/chat    cal        calendar    date
     lock        pwd        uptime        man
     pr        cmp        diff        find
     grep        head/tail    sort        uniq
     wc        kill        ps        tee
     time

 I know that some operating systems will not have some of these commands, like
 MSDOS would not have 'who' or 'ps'.  Those will be represented by 'N/A' in the
 chart.  I would also like to have the commands for entering both common line
 and full screen editors, especially for the ones that come with the operating
 system.  Not the editor commands, just the command to get into an editor.

 After this project, and if it gets a good grade, my next project will probably
 be along the same lines with the exception of making a chart for editors, both
 full screen and line.

 All information and help would be greatly appreciated.  Please mail all replies
 so I can be sure to collect them all. And if you are interested in the
 "aliasing
 templates", mail me and I will get them to you upon their completion.  If there
 is enough interest in them, I may post them to the net.

 Sorry about the cross posting but I wanted to get this to all the groups that
 dealt with a different operating system.

 Thanks for your help.

 Subject: Copyrighting programs based on PD may be ruled invalid

 In a recent response to Apple's "Look and Feel" lawsuit, HP maintained
 that the Mac's graphical interface is based on work done by other
 companies - in particular, Xerox Corp.  HP's filing further alledged
 that Apple obtained copyright registrations on the screen display
 fraudulently by not disclosing to the U.S. Copyright Office that the
 Mac's display was derived from Xerox's work.

 This is an interesting turn of events.  If this is upheld by the court
 it could invalidate the copyrights of all shareware and commercial
 programs which contain a substantial amount of public domain code.

 I wonder how that would affect the SEA vs. PKWare suit?

 Would it make ZOO's copyright invalid?

 How about all the copyrighted file transfer programs out there which
 use the Ward Christensen protocol (popularly called XMODEM) and all
 those YMODEM and ZMODEM programs based on Chuck Forsberg's PD code?

 Dr. Dobb's Journal published a CP/M emulator (in 68000 assembly language)

 Subject: CPT 8xxx File Transfer

     I had the dubious honor of doing some file transfer to/from
     CPT 8xxx systems and still probably have a data processing
     mode floppy around with XMODEM on it.  I know I used an 85xx
     and I guess an 82xx with it, so if you want to get that I'll
     see if I can dig through my junk and find it.  Around 2-3
     years ago when I did it there was no Kermit for it, and as
     I visited a CPT rep in 'D.C. several times to get it all worked
     out I'm doubtful one exists.  I'm not sure if I had the source
     to it or just an overlay file.

     I don't have access to a CPT any more but if you can dredge up
     a pre-formatted data procesing mode floppy I'm sure I can bum
     some time on a 8" system somewhere to copy the junk onto it.

 NOTE: My company deals in IDRIS product for ATARI ST.

 IDRIS for the Z80 is a very old product, and Whitesmiths probably would not
 sell it to now.  IDRIS however runs on may different processors.  IDRIS 3.14
 which I have on my ATARI MEGA-4 (mc68000), has WSL ANSI C compiler, X-Windows
 and TCP/IP.

 I have never seen or heard of QPLUS, if and when I do, and if it is good and
 properly priced, I might buy it for my Oz-1.

 Subject: CP/M+ <-> Apple DOS3.3 file transfer

 Hello, net.wizards:

 I own an old Apple II Plus, and have installed a "CP/M Card [TM]" from
 Advanced Logic Systems.  The Card runs CP/M 3.0 in a banked memory
 configuration.

 What I am looking for is a way of converting files from CP/M format to
 DOS 3.3 and vice-versa.  I have looked into CP/Muffin from A.P.P.L.E., but
 it does not transfer files to CP/M format, and for some reason I have not
 had much luck coaxing it to transfer file from CP/M to DOS either.

 I would appreciate any leads you can give me.

 Many thanks in advance,

 Subject: CP/M+ BIOS

 I own an old Apple II Plus system into which I have installed a "CP/M Card
 [TM]"
 from Advanced Logic Systems.  The Card runs CP/M 3.0 in a banked memory
 configuration.

 My application is a disk conversion program which will move files to and from
 CP/M and Apple DOS 3.3 formats.  It seems that making BIOS calls will not
 work properly when accessing the disk, as most of the BIOS related to disk
 activity reside in the bank opposite the application code.

 I have tried setting my disk access parameters by calling the BIOS SELDISK,
 SETTRACK, SETSECTOR, SETDMA, SELMEM, and SETBNK routines before calling READ.
 The result is that this sequence of calls will in fact transfer the data into
 my buffer if it happens to be in the area of memory that is shared between the
 two banks (no surprise).

 There are two reasons why I don't use the code that works:  First, SID is
 loaded into the part of memory that is shared between banks, so my broken
 program breaks worse under the debugger; second, my programming environment
 (one of the C implementations) makes it hard to allocate my transfer buffer
 in the shared memory area as that is where the stack resides.

 Has anyone solved this problem?  Or does anyone have any suggestions for
 anything I have left out?

 Second, I see that the BDOS provides a "DIRECT BIOS CALLS" function which
 takes as a parameter the address of some sort of parameter block which
 presumably contains parameters that are loaded into registers before calling
 the BIOS.  Does this facility overcome the bank dependence of the BIOS?
 What is the format of this parameter block?

 None of the literature I got with my Card has the information I need.  Neither
 does the application note describing ALS' banked memory implementation, nor do
 the other CP/M books I've bought over the years.

 Any help you could give me would be much appreciated.

 Many thanks in advance,

 Paul Sander

 "Z-System" is the name for the auto-install versions of ZCPR.  There
 are two products -- NZ-COM for CP/M 2.2 and Z3PLUS for CP/M Plus
 (3.x).  Functionally, they are virtually identical.  The command
 processor is the latest ZCPR v 3.4, containing significant advances.
 They run the same Z-System applications and tools.  Installation is

 Subject: Need Disk Parameter Block for Amstrad WPC (6586?)

 Hello -

 I've been asked by a local to move some PD software onto a 3.5"
 diskette connected to an Amstrad WPC.  I'm told this thing is a CP/M
 machine.

 Does anyone know the disk parameter block information for this
 machine?

 Regards,
 Mark

 E-Mail is best.  If sufficient interest, I'll summarize.

 Subject: a very naive Question???

 The article is inaccurate.  System V has virtual memory of almost
 any definition.  Originally System V had problems with virtual memory.
 There are two differing definitions of Virtual Memory.

 The more liberal definition says that Virtual Memory provides for swap
 extension of real memory and some sort of address translation.  UNIX has
 always done this.

 The more restrictive definition is that some mechanism such as paging or
 segmented swapping exists as well.

 The difference is summarized in the following.  Suppose you have 1 M
 of real memory and you want to run a 2 M process.  Prior to recent system
 V versions, you were out of luck.  It always expected to load a whole
 process as a unit.  On paging systems, it only needed to bring in the
 parts needed for the execution of the current instruction.

 The virtual memory argument was best summarized by Bruce Crabill of
 the University of Maryland.  "It ain't virtual unless it's not all there."
 This means that the liberal definition is kind of weak if you have to
 have real memory to back your virtual memory for any give process.

 -Ron

 Of course, they may have meant VM as Virtual Machine.  It is doubtful
 that anything other than AIX/370 is going to support that.

 Subject: cpm and aztec-C

 Hello,

 I was wondering if anyone has a version of Aztec C or just the manual
 that they are willing to sell.  I am doing some work for a company who
 has a licensed version of Aztec C but cannot find their manuals.  Manx
 will not replace the manuals unless you can document a thieft or fire or
 similiar circumstance.  what is the most current release of aztec C for
 cpm-80?  another thing that im curious about and im sure its in the manual
 is what is the com file czii for?  any info on aztec C under cpm would
 be greatly appreciated!

 Subject: Turbo C

 We have recently taken delivery of a used dual-drive Northstar Horizon.  This
 unit has a Z80A and 64K of RAM.  The system is currently running CP/M version
 2.23a, and has a copy of Turbo Pascal.  I prefer to program in C, and I have
 been wondering:

     1. Did Borland ever offer Turbo C for CP/M?
     2. If so, is there any way of obtaining a copy, now?
     3. Are there other C compilers available for this system?

 Also, how concerned should we be about the supply of 10-sector diskettes?
 So far, it sounds like 3M and Verbatim are still offering them.  The few
 distributors (all mail-order) who still accept orders for them have had
 none in stock; the risk of dead inventory is apparently too great.  Has
 this been other people's experience?  My project manager has been joking
 about punching our own holes with a straight pin.

 My apologies to the members of the NORTHSTAR-USERS mailing list, who have
 already seen this posting; I wanted to reach as broad an applicable group
 as possible.  Thank you.

                 -Jim.
