Even the Series 3 machines were amazing in terms of what had been packed
into the ROM: no Linux AFAIK, but with the SIBO platform, there is
multitasking available as well as a windows server and an IP stack (from
the PsiMail product). These are just examples, see the Psionics files
for more information.

I prefer the Series 3 over the Series 5 because there is no pen. I
always fear leaving scratches on the display...

For the "dumb terminal" topic, there used to be a good VT100 emulator
from a company called Yellow Software for the 3a (also runs on 3c /
3mx). I bought it together with my first 3a and was a happy user of both.

Since then, the need for Telnetting into a host came up, and the trouble
is that Yellow's emulator is not capable of using the IP stack, but only
supports the serial interface.

So, I rolled my own VT320 emulator (I call it "V-Tel"), which has been
tested with VMS, True64, and Linux, and which supports the serial
interface directly as well as through PsiMail's TCP/IP stack. Editors
like vi or TPU do work, MONITOR SYSTEM on VMS is lacking the graphics
character set yet, but all control sequences are interpreted properly.
Perhaps I find the time to add double-width/double-height characters and
the semi-graphics font during Christmas holidays.

It may be a bit late to put V-Tel up as shareware, and it may be a bit
too early for the Series 3 to be discussed here, but if somebody is
still looking for a portable terminal, this solution works very well for me.
