    This Data General disk drive came into my possession today : sadly it was changed into a showpiece by directly driving the disk and not much else. Probably toast by now.. I can recognize the serial IO typical of the micronova series, but not much else. If someone can ID this drive?

    Tektronix 4052/4054 Multifunction modules available.

    So I created a mutifunction module / ROMPack for the Tektronix 4052/4054 - This covers the ROM-expander (Tektronix 4050E01) functionality in that it allows the equivalent of up to 8 ROMpacks into a single ROMpack module. ( Actually 16, if the TEK would have been able to handle that...) -...
