The machines need to be set up with their matching reference disk, MCA adapter cards need their ADF (configuration) file to work. For all things PS/2 head over to Peter Wendt http://www.mcamafia.de/mcapage0/mcaindex.htm This looks good too: http://ps2page.tripod.com/ as well as this: http://www.computercraft.com/docs/ps2sect.shtml Peter Wendt (see above) has this PDF on the workings of the Microchannel architecture: https://dl.dropboxusercontent.com/u/55419307/Microchannel/ibm_hitra02.pdf Last edited by rfka01; 12/14/14 10:16 AM.

Downloads can be found here http://ps-2.kev009.com/ncr3xxx/pc_library_3432_37.html I've dumped the BIOS and keyboard controller ROM and took pictures of the mainboard and cards. https://dl.dropboxusercontent.com/u/55419307/Microchannel/NCR%203433.rar NCR DMV- DEC Rainbow- Siemens PCD- ITT 3030-Oly People- Acorn A5000- Olivetti M20
