I'm looking for flash memory packaged on 72 pin simm boards,
similar to the 72 pin simm EDO memory that was standard some
time in the 1990's for PC's. I think a number of kinds of printers
and other devices from that era used flash in this format,
usually in 2MB capacity. I'm looking for bigger ones, 16 or
32 MB. I know this was made, because I have a 32MB one (which
seems to no longer work) and a device that used it for storage.
However, I don't know how standard it ever was.

Does anyone know about this kind of flash memory? Does anyone
know where it is still sold?

Also, does anyone know where I could get testing/burning equipment
to read and write this kind of flash memory and play around with
it?
Double check the number of pins. 80pin flash SIMMs were also common. HP, and Cisco, both did the 72pin modules, and Cisco certainly still does the 80pin modules in larger sizes. Small sizes will be harder to find. A search for:
MEM-381-1X32F should find the Cisco part.

Thanks for the response. I've double checked and the simm is definitely
72 pin.

After taking another look at this module, I'm starting to think it is
probably proprietary. It has 4 Intel E28F640 chips on it, which are 8MB
flash ROMs, and one E28F320, which is a 4MB flash ROM. So guessing from
its function, I think it probably has 32 MB of raw data and 4 MB for
settings. This would be a device specific format.

Hmm. The company that made this has long since stopped selling this
line, so I'm probably out of luck.

Which raises the question ... what are the legal implications of copying
the board? There are the flash chips and a few other IC's and some
caps, etc. Probably everything on this board is still easy to obtain.
But I don't know a thing about how this works legally. Is it likely the
company patented the design of this board? How possible would it be to
make a work-alike board?
