Re: LF: Upgrading the CPU
[Prev][Next][Index][Thread]
You might not need the expander to upgrade the TI-92's RAM. There is an
empty space where a ram chip can be soldered on the main board of the 92,
and supposedly clearing bit 0 of port[600000] sets the calc to interleave
mode, allowing for 256K of ram. I ordered the RAM chip ( TC551001BTRL-85L )
and will install it when I get it. I'll post my results.
