This is a program that I wrote in Amiga E v2.1, because there was no similar program, and the only sheet is from commodore, and is red, making it very difficult to photocopy. Anyway, this is my program, it requires 2.04 (I think, I have no 1.3 machine to test it on!) It contains all the diagnoses from every check sheet I have access to, including breakdowns of port problems, disk drives problems, keyboards, graphics, audio, parallel port problems, and about everything I could think of, even mouse & joystick problems. It is designed to use REQTOOLS.library(sorry, I can't remember who wrote it), anyway, it works fine using a 640 screen(although I use a 698x283!) I hope that it will work with REQ.library, as well as asl.library(Although I wouldn't know why anyone would want to use them, as reqtools is sooo much better!) It is designed for certainty with the A500-A2500 in mind, although I am not sure about the A3000, all my tech friends say it will work with the A3000(with possible exception to graphics problems.) I have no certainty of its usefulness with AGA machines (1200 & 4000) USE: prompt% ECSDiagnosis Simply point and click on your problem, and a (hopeful) solution will appear! Simple as that. INSTALLATION: Put it anywhere in your path (ie c: bin: user:) Shareware Registration: I am asking for a $2 donation, this will get you a version without the requester at the end, and any future versions I may or may not write.

P.S. If these solutions don't fit your problem, try blowing the dust out of the system, it just cost me $50 US to get the dust blown out of mine!
