I am looking for ROM dumps for the NI card as well. I've dumped ROMs from most other cards. I've placed there temporarily here:
https://www.retrotronics.org/tmp/3b2_romdumps.zip [1] I've disassembled the ones I have. They all appear to be based on the same CIO reference firmware, mostly compiled with a C compiler, share 75% of code between them, do not support PIO access other than to return the card id code and accept a slot number, and communicate with the host OS through in/out FIFOs at an address in memory based on the card id. -Alan On 2017-03-26 00:26, Seth Morabito via cctalk wrote: > I'm trying to track down ROM images from AT&T 3B2 expansion cards. > I've started with the EPORTS serial card, which I have.
