Don't ask your question here, do it there BIOS image collection - requests, discussion etc

(btw I have added cache to one of these board, you don't need to touch the BIOS at all)

Trying to identify old hardware ? Visit The retro web - Project's thread The Retro Web project - a stason.org/TH99 alternative

I got it without BIOS+KBD-controller. But it works with..:
- A433C-C/A450C-C, by J-Bond, found here
http://www.minuszerodegrees.net/at_clone_bios … _clone_bios.htm

- MRBIOS V018B401, found here:
How about a MR-BIOS ROM file repository?

Both need to be split in HI/LO, attached in file.
