Aloha!
I recently received a Unitron U-2200 logic board. What's missing are the ROMs, including the Boot ROM and the character ROM. I do have the ROMs for the U-2000, but in my research the two boards are different to the point where the U-2200 auto boots into CP/M by default, which is the original state that I want. This ROM came in the form of a single 27128 ROM.
There is also an "upgrade" ROM kit which includes ROMs for Apple II compatibility, which is something I'd also like to get my hands on. The ROMs come on a small PCB that connects to the 28-pin boot ROM socket. I believe the total ROM on the board is 24KB.
I've already been to http://www.applelogic.org/UnitronAndI.html which talks a lot about the Unitron line. But, it lacks the ROMs for the U-2200.
I'd also like to get a hold of the original disks that came with this computer, as well as the 80-column card.
