Does anyone have any use for some Fujitsu MB8107 DRAM chips? From what I
can determine, these are the same as the TI TMS4060 4Kx1 "midi size" 22-pin
DIPs.
I've also got some Intel 2111-4 SRAM.
Cheers,
Chuck

That brings back memories!
Once wirewrapped a 32M byte RAM card for my Technico 9900 card
using MB8107s salvaged from bad Amdahl cards. Last of the unmuxed DRAMS I
think...

I believe you're right--12 address lines, 1 data in and 1 data out line.
The 4060's were also used on the old MITS Altair 4K DRAM card. Miserable
things--they had a tendency to change contents when RESET was toggled.
3-supply chips at that +12, +5 and -5 if memory (!) serves.

New subject: Xerox 820 5.25 CP/M disks
Hello. This is for CP/M gurus:
How can I do one CP/M bootable disk for the Xerox 820 ? I own the files, but
not one image disk, and I must do the work in one PC.
Of course, if someone has these disks in bootable form and could do one copy
it would be great.
Greetings
Sergio
