Title: ZIP RAM chips
Post by: Chain on July 05, 2005, 06:58:07 PM: anyone know where to get it? i need 8-16pieces for oktagon, a3000t etc :)

is it possible to use zip chips from any 4/8MB ram card for a1200? (those crappy cards for nothing good)

but they didn't reply me for months. Besides, they are in USA, so shiping cost might be high..

I sell some ZIP's on german eBay. I would send them outside from germany if needed :-)

And where would one for the schematics for said adaptor? Trying to track downs ZIPs downunder is a nightmare, not to mentions extemely expensive, last time I checked, 8MB's worth was AU$400 :-o

Post by: Chain on July 07, 2005, 11:08:01 AM: no schepatic, only pin to pin connections, and yes, its simpliest than adapt a large simm socket.

there is something similar:

Post by: alexh on July 08, 2005, 08:45:09 AM: There were two commercial Zip to Simm adapters. Both I think called AmiFast, one by ProV and the other by UK company RamJam (might be the same one and two vendors).

It would probably be cheaper to buy an accelerator or a DKB3128 nowadays though :(

Post by: Crusher on July 08, 2005, 10:24:42 AM: The picture (http://chain.3dgrafika.cz/temp/miss.jpg) Chain shows is Chipmem, is there any zipp2simm for Chipmem?

The other boards that are mentioned is for Fastmem(I have one from RamJam in my A3KD, it doesnt fit on the A3KT fastmem sockets.) :-)

Post by: alexh on July 08, 2005, 11:06:16 AM: Being only 2Mbytes, I guess they thought that no-one would ever want one. I am sure you can beg / borrow just one ZIP?
