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

Remember that adding a RAM cartridge won't give you more program steps or memory registers. It only expands the file space where you store programs.
