They (along with the SR-52 and TI-56) also had a bidirectional I/O port (usually used for a PC-100 printer) port in the battery compartment. Many clever folks came up with remote programmers and other peripherals for them.

Ah yes, I forgot about that, even though I also have a PC-100C printer. I never heard of any one using that port for anything but the printer though.
