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: http://www.gwg.nga.mil/ntb/baseline/software/TACO2.html http://www.mcamafia.de/mcapage0/mca.dat http://sunsite.bilkent.edu.tr/pub/sun-info/sunspots/v10n96 http://www.textfiles.com/internet/vendors1.txt Hope this helps.
