Looking for 90-92 TPI memcal

Throwing this out there on the slim chance somebody might have a sped density 90-92 5.7 TPI memcal for 7730 ecm laying around they would get rid of. Going to be adding adapter and custom chip but need the v8 tpi memcal for the factory knock retard EST chip and limp home proms. So if anybody has one would love to take it of your hands.

Thanks

I have a few left from past projects - they have all been converted to 28-pin DIP
sockets so that I can easily swap between an Ostrich emulator and the final EPROM.
I'd be willing to let one go.

Nice the R as the second digit on knock board are getting harder to find.
