No. Apple II Plus? What about the IIe? (Yep, got one of those too -- I'm sure this one really _is_ a IIe, and I'd be especially interested in knowing about the IIGS upgrade) What about the IIGS? I'd suggest language card, parallel printer card -- preferably one of the better ones such as a Grappler card, serial card, 80-column card, second Disk ][ card and two more drives if you want to run UCSD, hard drive controller, ... The //e takes the same cards, except that it already has 64K RAM and has no need of a language card; it also has provision for a special 80-column card in Slot 3, set back from the rest of the slots. -- Pete Peter Turnbull Network Manager University of York
