I no longer have a TI system or a PC with a COM port and do not need
the TI 5.25″ diskette.
I want you to include the 5.25″ TI diskette, since I still have a
TI system with RS232 Card, Expansion Memory, and TI XB or E/A,
and a PC with a serial port or COM->USB port. The diskette can
be ordered later at no charge if circumstances change.
I meet all the requirements immediately above, but my TI system only
has a SSSD drive. Please split the 5.25″ diskette into two
SSSD diskettes.
