The membership kits would be similar to the TI, although the TMS9900 was
severly crippled in those models. I have one, too; have you checked out the
TIPI module to get yours online?

The Membership cards, at their most basic level, provide a switch/LED
interface by which you can toggle in programs, byte by byte, and run them.
However, I think that all of them also have some kind of serial interface,
whether RS-232 or USB-compatible TTL. At any rate, with the ROMs supplied by
Lee, once you connect to the computer from a terminal via serial, you are
presented with a menu allowing you to do things like mass-import or -export
ranges of memory, examine registers, change values at memory locations, reset
the Program Counter, etc. They also usually have some variant of BASIC that
you can use. For those kits that don't have storage options, capturing and
resending data from the terminal is the only way to save and load programs.

That would be interesting. I've seen plenty of project to make a WiFi modem
with all of the traditional blinking lights and whatnot, but I haven't seen
any involving an actual telephone connection.

I have a Pi dedicated to that as well :) Although I haven't been able to
spend as much time on it as I'd like, I did find Moshix's Youtube videos
about Hercules and MVS 3.8j extremely helpful.

In addition to emulating PDP-8s and -11s, as in the PiDP projects, SiMH can
also emulate a VAX. HP, the owners of VMS (via Compaq) used to offer
yearly hobbyist licenses for VMS, but has discontinued doing so the last few
years.
