I searched on this but could find nothing specifically about my questions. It seems the search engine is not that specific and if I put IIe in the search, everything with IIe in it comes up. It appears to be doing an 'or' on keywords rather than an 'and'.
I've got a couple of questions to those that might have done a DIY enhancement. (one using EPROMs rather than ROMs)
1) Do I loose anything by doing this? i.e, Will there be any significant incompatibilities caused by the enhancement? (not specific to using EPROMs)
2) Will the IIe motherboard accept 2764 and 2732 EPROMs without modification?
