In order to keep the off-topicness, I'd like to add that I own a couple
of VIC-20 cartridge boards. Those take two 4K EPROMs each, usually 2732
but I'm quite sure I've seen some identical boards fitted with 2532's.

If the 11th address line (A11) is not required, is it even electronically
possible to engineer a board that takes 2532 OR 2732 chips, or did I
dream about it? My EPROM programmer doesn't natively support 2532
although I have a few of those chips as well, so I couldn't try i
myself.

Wow, the BBC Micro list discussing the ZX-80, going over the Dragon 32
to the VIC-20. At least that brings back the topic to 6502 computers...

Best regards
