Hm. Neither one of these seems to have any RAM on it.
A bit, but not much. They don't even say all that much about just what
the darn thing does.
Well, since I was digging for the WDC LCD thingie, and didn't find it, I
should mention that I found a brief description of the Ad-Con boards. Here
goes:
AdCom2-M
128K Bytes RAM
2 serial ports
Data encryption
Synchronous mainframe link
Async, Bisync, HDLC, SDLC, X.25 terminal/protocol emulation
Introduced 1984, Cost $850
This, oddly, was not the high-end model. The AdCom2-I had double the
memory, was introduced in 1985 and was priced at $1495. Software was
included with each board. There was also a plane-Jane AdCom2 with a
printer port, clock/calendar and 64K of RAM, no encryption, introduced in
1983 and listed at $275. Given the correct spelling of the thing (or at least
how the field knew
it), I find references in:

Hope this helps.
That third reference mentioned a price of $2295 which is even higher yet. :-)
Both that and the fourth reference seem to be talking about X.25, whatever
that is. (I probably knew what that was at some point but the brain ain't
what it used to be. :-)
