Well ... those chips are 256x4 devices. I have a Pacific Data Products board in
one of my LJ-iii's but it uses 1Mx1's, which are 18-pin devices.

Does it happen to say what printers the boards are
used in? I have a Pacific
Data Products board from a Laserjet III that has 2 mb worth (16 chips)
soldered on and two banks of 8 blank sockets to add another 2mb. The chips
are marked HY51C4256S-C and are 20 pin DIP chips/sockets.

Subject: 1mb x 1 memory chips for printers
I have around 50 or so printer memory expansion boards, ALL unpopulated. I
guess they ship them blank, then the vendor installs the memory as units
sell, but I don't have any chips. Where is a good place to find memory
chips for printers ie 1 MB x 1 bit? (sockets are 18 pin I think, but it
doesn't go into anymore detail) Given the 16 to 24 devices per board I am
guessing I would buy maybe in lots of 100 or so.
