Not true!  The SRAM was on a separate chip and socketed.  I know
because I modded mine w/ a 4x memory expansion (this was over 10 years
ago, and I've long since sold the TX81Z, so don't ask me for details,
I think it was just a matter of using a 4x bigger SRAM & routing the
select lines to a switch).

It is pretty difficult to mod most digital synths, though.
