     The designation you mention (8305d) sounds more like a date code.
According to the schematics in the IIe Technical Reference Manual, the 'ROM'
would be a 2716 PROM (or equivalent ROM) sitting next to the KB encoder IC (a
3600 PRO).


     Before going to the bother of ordering a new ROM, be sure to try scooching
up and resocketting the KB encoder and KB ROM. And, (if in sockets) do the same
a couple other IC's, a 74LS245 (IC UB2) and a 74LS374 (IC UD3).

     It may sound "too easy" to fix computer glitches by just resocketing IC's,
pulling and reinserting Slot cards, cleaning connectors, etc.; but, this stuff
works so often that it should always be tried before looking for new parts.
