Depends. If you plan on calling nothing but PC-d00d BBSes, you might be better off with the HST. If you know folks/sites with Telebits, then buy it *now*. The Telebits use a protocol called PEP that splits your data into a little over 500 separate channels, each running independent of the other. It's driven by a 680x0 and a DSP (our T1000s are effectively 5-7MIP computers :-). What this means is that Telebits are rock-solid data links. Our local Telebit dealer did the following demo: Hooked a telebit onto my Sun sparcstation, putting a phone *between* the telebit and the wall jack. Normally, one plugs the phone into the modem (and you should for regular telebit use :-) so that the modem can take the phone "off line" while using the phone. However, she had a reason.. She then dialed the Telebit in her office, logged in, and started up a game of nethack. While I was playing, she picked up the phone (one the wrong side of the modem, remember) and started saying "la la la" very loudly into the phone. She then proceded to beat the receiver on the table, and repeatedly switch flash. All that I noticed was that NetHack was starting to slow down, as if I were playing at 2.4kbps instead of 9.6kbps. A little bit after she stopped making noise on the phone, the speed went back up. Way fucking cool, IMHO. I know have one at home for dialing into work (we bought a bunch there :-). I *never* have line noise in a PEP connection, but a normal 2.4kbps connection is so noisy I can't use vi... The T2500 also does V.32, if I remeber correctly, so you can talk to non Telebit 9.6kbps modems. -- J.
