Dear all,

I had the unique opportunity to buy a pocket TI-95 PROCALC calculator
together with a Math Statistics, a Chemical Engineering library module,
a PC-324 printer and a PC interface for around $40 here in Switzerland.

Now I'm considering how the internal memory of only 8kByte could be
expanded with a RAM memory module (RAM cartridge) with 32 kByte. In my
opinion, this should work, since a ROM expansion (ROM cartridge) with a
memory size of 32 kByte was also available for the TI-95 PROCALC calculator.

What do you think about that? Has anyone worked with such a RAM
extension before? Probably built by yourself. Of course, I would have to
develop it first. I imagine using a SAMSUNG KM62256CLG-7L (see
https://app.ultralibrarian.com/details/Samsung/KM62256CLG-7L?uid=93ce5ab184e94c09)
32k x 8 bit low power CMOS static RAM (70ns).

Would anyone other than me be interested in such a 32 kByte RAM
cartridge? Thanks in advance for any help or comments.

Best regards,
Lorenz
