If it can do the basics tests automatically on boot and spit out the results, then that should be fine anyway.

Yeah it does this. If you actually get as far as the menu your machine is in pretty good shape.

I'll burn it to a couple of eproms ready tomorrow night.

What size are they 27c512?

Sweet. I would leave it at that for now then.. most likely some chip is failing to init preventing GEM from booting up, its just working out what...

There is a rom image for each machine type. Very much depends on what your machine is. I've provided HI and LO split binaries of each version too incase you have 2 roms on your machine variant.

Ok cool thanks. Will burn it to a couple of eproms for the diag cart and then use it once I've got to the bomb stage.

Just gave the STE ones a quick blast...

Via putty.

K, this whole DiagROM is seriously cool. The Atari cart has it's use, it's awesome to test keys on keyboard, all the ports etc. But this takes it to another level. If this can be expanded to be a dead test cart as well it would be perfect. But I suppose it already is?

Problem with the cart is it needs TOS to be partly working in order for the cart to boot...

With replacing the OS ROM's with this, it boots by itself and runs its own OS to do the tests. So it can debug lower level issues where the cartridge port may not even boot up.

DiagROM now needs to be un-Amiga'd for more ST use.
