Diagnostic ROMS

This might be the wrong forum?

Anyway, Today I decided to release to the public the VERY VERY Early beta-state of my Diagnostic rom for the Amiga:

http://www.diagrom.com

Please do download, test and come with suggestions etc.

And it's the right forum.

Do write on your site the main point: it's a diagnostic ROM for non working Amigas and you download it and burn a ROM to plug into your machine that isn't working to find out what's wrong with it

(Á la recent cartridges for Vic 20 and C64.)

Also share in Amiga groups on Facebook

This should be very sweet. I've spent a lot of time over the last year relearning board level repair. So anything to make some of the diagnostics easier would be great better than just a few screen colors and flashing lights.

Great idea!! Looking forward to test it!

Any chance of an idiot's guide?

I've a dead A1200 motherboard I'm trying to revive, but it's still dead after replacing caps etc..

idiots guide is very hard to do. someday I might so somekind of writeup.

but. a dead motherboard is close to never fixed by a recap. except the 600 where one cap (and the ceramic C611) can hold reset low..

Mr.Flibble · 21 August 2016, 00:43

Yeah, replaced the caps as they were looking a bit rough, but don't want to start replacing random components without having some idea of what's wrong, although if I'm not getting anything out of the screen as it is, I'm not sure if diagnostic roms would help or not..

Look at powerled, if it doesn't change brightness chanses are VERY small the diagrom will startup either.
(you know, the Amiga ALWAYS starts with half brightness of the led, it is turned on among the first instructions in the kickstart)

so no brightnesschange = something holds the cpu to work. so check clocks, data and addresslines, they must be ok first.

Awesome, I'll check that first before playing with roms then
