My Micropolis 8250 has 901885-04 in it. There were reports that there was going to be a DOS 3.0 for the 8250 (like the hard drives). Maybe it is a prototype version of this, or something similar. I don't see why this would require another processor. - This message was sent through the cbm-hackers mailing list. To unsubscribe: echo unsubscribe | mail cbm-hackers-request@dot.tcm.hut.fi.
