Is there a commercial 128 Kbit x 16 EPROM compatible with the A2000
Kickstart ROM?
I'd like to do a little Kickstart hacking (NoKlickStart and KickFont for
example), but I've been unable to find a suitable EPROM to experiment
with.
If anyone is aware of such a beast I'd appreciate any info on where to
locate it, and an approximate price.

It should be relatively easy for a small PC board to be laid out, with a 40-pin header in the bottom, and 4 28-pin sockets on the top side, for taking 27512's (or maybe even 2 271024's?) Although I seem to remember reading about some nnn x 16 EPROMs that were being released a while back, I'm certain that they were 32K words, or maybe 64K at the largest... -- - Mike Shawaluk ...!uunet!marque!lakesys!mikes

I have seen kit in German papers with 4 EPROMS. They sell ready-made
with Virus Protectors, they have kits with program to make your own
programming and they also sell prommers. I can dig further into this
if it's interesting... I think the price was $25 without EPROMS, $50
for a ready-made with the virus hunter.
