Hi, All,
I unearthed what appears to be a Tektronix X terminal, marked on the bottom:
MODEL: X221CHT
SERIAL: <serial number>
LAN: 08 00 11 <xx> <xx> <xx>
KEY: <17 digit alphanumeric>
The connectors on the back are:
8-pin DIN marked +5VDC/+12VDC
PS/2 Mouse
PS/2 Keyboard
15-pin VGA
2x DE9-M serial
"RJ45" Ethernet
10Base2 BNC
several empty rectangular openings presumable for expansion mods
Inside is:
Sonic-T DP83934CVUL-25
TI TLC34076-135FN Video
SRAM
LSI LR33020MC-25 "GRAPHX PROC"
Tektronix 160-9461-00
29F010 FLASH EEPROM
2x 72-pin SIMM sockets with on SIMM installed, appears to be 4MB
Chip dates are frequently last 60 days of 1996. Two minor SOIC parts
have the newest visible date code, 9701.
I do not have the PSU for it and have not tried powering it on. I can
probably solder some wires to the back of the PCB to feed it +12V and
+5V, but I'm a little surprised to find zero information on the web
searching for variants of the vendor and model number.
Anyone here have any info? If it is an X terminal, it's probably a
brick without a somewhat sizable tftp area for it to slurp up.
Thanks for any tips, comments or pointers.

I'd guess that the human-readable model is probably XP221, though that
doesn't lead to a lot via Google. However you might find a usable PSU
under eBay #271338697806. Ouch, $80 + S&H.
Tek made some very nice X terminals, I worked with them in the '91-'94
period.
Announcement of the XP200 line is here: http://goo.gl/4DPXlN
(Too early to cover that model, though.)
There's a Linux how-to for supporting/booting Tek X terminals that
includes the pinouts for the power connection. Good luck with the 16
year old links for software, however...

Good luck,

Nah. Just going to jam some +5V into the right pins.

I've worked with some X terminals, just not these.

That's a great document. Very useful info in it. Enough to test out
the hardware. Bummer about the NCD ftp server not answering (unless
ftp is just blocked from where I am, which is possible).
Anyone have a mirror of the old NCD repo?
Cheers,

... depending on their definition of "patch". Makes me think of overlays to
original software (i.e. the binary equivalent of a source file patch), but
maybe it is a complete, self-contained archive of everything that you need
on the host side.
cheers
