Hi all, does anybody know of any software that can do thorough tests of chips like the 8253, 8259, 8255, 8237, etc? And that can run on an 8088 or 80186? Something that really tests out all or at least most of their functionality.
I started writing a new XT-class PC emulator to address the problems (and horrible code architecture) in my old one, and I'm trying to identify bugs in the components. I know there are at least a few, since the Super XT/Turbo XT BIOS from phatcode.net is the only one that doesn't give me any issues booting.
For example, the stock IBM XT BIOS invariably gives me a 101 error and halts, so that one seems to be tripping up on my 8259.
