I just got a VB EP-ROM cartridge (woot!) and now I am looking for some 4 and 8 MBit EPROMs and maybe an eraser to use with it. I think I need M27C4001-12F1 but I am not entirely sure. It seems that those are no longer produced, though, so maybe someone has some of those or knows if I can use other ones?
Heh… if you still need these, let me know… I’ve got a bunch of 27C080’s (which IIRC work in these carts)… you could also get some 27C4001’s, or 27C040’s on ebay or some place like that.
