If I burn an Eprom, what modern Eprom is recommended? I have a TL866A Eprom programmer.
As for the cartridge route. The C version is the one with the silver label?
Cartridge route you refer to is null and void being
false flag fake news as in you can't get there
from here.
Atari used extra special custom chips for all their
game cartridges with odd pin outs and chip select
polarities such that a standard eprom equivalent
doesn't exist. So you can't just plug and play.
On purpose. Think about the piracy that would
have existed if this hole were not plugged solid.
2364 at 300ns speed is the eprom used there, due
to lack of popularity you may find that finding
an eprom burner that does 2364 eproms may be a
challenge. But if you have that and you have the
code and you can find those eproms, then it's a
done deal.
Otherwise you can purchase an adapter board that
converts a standard 2764 over to 2364 pinout and
use that to sport a 2764 on your XL/XE mother
board.
http://store.go4retr...m/2364-adapter/I've done this manually using a 2nd stacked
socket but it is a hack job and it looks like a
hack job. And that part can't be fixed.
The 23xx adapter also available there might be
made to work for Atari game cartridge eprom if
it were a SINGLE 8k chip, but the vast majority
of game cartridges are using two 4k chips which
don't fit the 2364 pin wise to begin with.
Cartridge route then really doesn't exist,
takeaway is it's not plug and play precisely
because Atari made it that way on purpose.
eBay guy is just being honest, he's never
done it so he wouldn't know but that's the
exact chip you need and it just drops in
there and works.
