ti99iuc Posted September 21, 2021 Share Posted September 21, 2021 (edited) For my computers I still using the standard and old cartridge from Texas Instruments - Diagnostic (1979) I do not know if I lost something somewhere but, Is there an alternative updated recent diagnostic software solution to test the internal components on the motherboard of our TI99s?

+Ksarul Posted September 21, 2021 Share Posted September 21, 2021 There is the CorComp Peripheral Diagnostic Module, and there are several specialized memory test programs (JediMatt's memory tester, SAMS AMSTEST, MEGTEST for HRDs, and probably a few others). Other than that, not too much. 1 Quote Link to comment Share on other sites More sharing options...
ti99iuc Posted September 21, 2021 Author Share Posted September 21, 2021 (edited) @Ksarul yep, also the old CorComp, right... but I was just hoping for something more comprehensive and maybe current diagnostics (not just for memory) for the basic TI99. I already use the nice JediMatt's memory tester for the expansions indeed. I just miss a good diag tester of the MB chips, something Like an: Ultimate Diagnostic 20xx that include all and maybe can tell the exact chip (or more) of VDP broken or sound chip and what other... an automatic full diagnostic. anyway if you don't mentioned, it is not recognized Edited September 21, 2021 by ti99iuc 1 Quote Link to comment Share on other sites More sharing options...
sparkdrummer Posted September 22, 2021 Share Posted September 22, 2021 These aren't really updated diagnostics, but you might find them interesting. KNOWWARE DIAG.pdf TEST.dsk TEST2.dsk 6 Quote Link to comment Share on other sites More sharing options...

Such features usually require that the design includes the necessary feedback routes. Which adds cost, and that's nothing you want in a home product like the TI 99/4A. Memory is easy enough to test, as you can both write to it and read from it. But a computer like the 99/4A usually can't test the sound, because it can only generate it. It has no way to "listen" to what comes out, so it can't determine if the sequence used to generate the sound really was successful. The same is true for the image on the screen. In production, it's common to include a number of test points on the PCB. Then a testing device is probing these test points, while the computer runs some specific software. Then the computer may emit sound, and the test device will probe sound output line to see if the desired tone is actually emitted. 1 Quote Link to comment Share on other sites More sharing options...

I have tested them and I must say that they are useful a lot! Overall test.dsk is really close to the one I would like to have. Better was if in Cartridge format but it is a start. Also Test2 is really interesting for the Video and Sound but overall for the third choice: I just have an error with the 7th option but I will try on the real thing. thanks again for sharing these. 1 Quote Link to comment Share on other sites More sharing options...
sparkdrummer Posted September 22, 2021 Share Posted September 22, 2021 No sweat Ciro. The first disk by Know Ware was a commercial release I believe. Have you tried Advanced Diagnostics by MG? 1 Quote Link to comment Share on other sites More sharing options...

I can't figure out how to get past Page 1 of the menu on ADVANCED DIAGNOSTICS. Function-7 brings up the menu, "command List pg 1." But how to get to pages 2,3,4...??? @sparkdrummer The manual says CTL-E and CTL-S but those do not seem to work?

KNOWWARE DIAG.pdf 40.84 kB · 41 downloads TEST.dsk 90 kB · 35 downloads TEST2.dsk 90 kB · 37 downloads Have a simple joystick 1/2 test program @sparkdrummer ? It appears the 1979 Diagnostics program was designed for the cancelled analogue RF controllers, not Atari style joysticks.
