I have for sale 1Bit DRAM chips 1Mx1 model # M5M41000BP-10 (100ns). These are left over NOS that I got long time ago. I have around qty 100 of these.
works in SupraRAM 2000 8MB RAM expansions http://amiga.resource.cx/exp/supraram2000 , for others check your manual.

Qty 8 will give you 1MB, qty 16 will give you 2MB.

$1.00 each sold in qty 8, so $8.00 plus shipping (shipping in US should be from $5.15 if payed by gift.

Thank you

Hey amiman
I'm interested but you can ship that for like $3 via USPS First Class mail. If you are willing to do that i'll go for 1mb for my a3000 chip ram. Thanks

I have only qty 10 left of the NOS.
I also have some used ones I pulled from my RAM board, different brand by NEC D421000C-10 qty 24 for $0.75 each. Some pins are bent and not that perfect.
and
Another used batch, MT4C1024-12 (120ns) qty 16 for $0.75 each. Some pins are bent and not that perfect.

Thanks
