Unfortunately, I think 441000 is 4Mx1 instead of 1Mx4.
The info I have on the chips I need (and it sounds like Ethan needs):
20-pin DIP memory chips
(16) 1meg x 4-bit dips make up a bank of 8mb.
Should be 60-ns

non-parity
An example would be Toshiba TC514400AP-60.
Other manufacturers might use the following base part numbers:
Fujitsu MB : 814400
Goldstar GM : 71C4400
Hitachi HM : 514400
Hyundai HY : 514400
Micron MT : 4C4001
Mitsubishi M5M: 44400
Can anyone verify that 441000 is 4Mx1 ?
Thanks
Keith
P.S. I'm not picky. If someone has 80ns chips with no FPM (would that
be edo?) that would work too! :)
Not 411000s -
those are 1Mx1s unless I'm quite mistaken. I have a
small pile of those. What I need (as mentioned in the subject line)
is 1Mx4, perhaps known as 441000s, perhaps by other numbers; and I
agree with Keith that they are uncommon in DIP format (which is what
the Rejuvenator is prewired for - remove 8 256Kx4 DIPs, install 4 1Mx4
DIPs).
Ops, sorry! :) I though 441000 and wrote 411000 :) As I told you,
these are (were?) very common memories. I have a bunch here, drop me a
mail if you are unable to find it anywhere.
