No, but it's certainly revealed a vast array of different hardware being used.
To add a new dimension to the discussion, I wonder why individuals chose what
they use?
My first foray into packet was with a second-hand Paccom TNC220, a
dualport, HF/VHF (but only one at a time) TNC. My experience with that
device was enough to make any sane person give packet away. Its performance
was totally unpredictable, which, I think, is why the original owner sold
it. It makes a useful paperweight, and one day I might rob the AMD chip and
build a Baycom style modem with it.
I then got into Baycom modems and at one stage had three running under BPQ
on a Win95 machine, which I suspect wasn't a good environment for so much
interupt activity, but it was a means to an end at the time. Prior to the
Win95 experience I had the TNC220 and a Baycom modem running on an old
10MHz AT computer under Linux. It booted and ran from the floppy as a
two-port packet switch.
About this point in time I started running a BBS, and between trying to get
the TNC22 to work reliably (with a variety of EPROMs), and Baycom modems that, I
think, weren't being reliably serviced by interupt requests, I reached
frustration saturation and bought a Baycom USCC>4 card with three modems.
From this point, I never looked back. When a quantity of second hand
MFJ1270BT TNC's became available I bought four of them, and they're all in
service.
The advantage, in my opinion, of a TNC being true TNC2 compatible (as is
the 1270B) is the variety of alternative EPROM images that are available.
This point was really driven home to me with the TNC220.
Apart from the splurge on the USCC card, my choices have been based on
economy.
Cheers ... Ray
