Hi folks, I've recently acquired an Apollo DN100 I'd like to restore to former glory. Sadly, there are no schematics anywhere that I can find. I have seen this alluded to, but do not have a part number- anyone got a lead? Even better would be to find anything describing the PALs in the system. Separately, there is a 14" Priam DISKOS hard drive in here- not with the Priam interface used by the later SAU2 Apollos (DN300, etc.) but something else- perhaps the early ANSI interface option provided by Priam. If anyone has leads on - 1) The failure modes of these drives and 2) A replacement ? advice would be much appreciated. Thanks, - Ian
