The bad news is that the EPROMs are 27210's (64K X
16 bit) parts.
Which manufacturer ?
Apparently these weren't popular enough to either
make it into the
"mainstream" or into over stock :-(.
Mine VLC have all 27c1024 in them. I ordered/got this parts without any
problems few weeks ago.
Digi-key, Mouser, JameCo, Future-Active, Wyle, all
came up empty. JDR's
web
site claimed they had them but the order failed and
said "call customer
service" :-0.
You probably asked the wrong questions ;-)
cheers,
