Finally, after digging out a terminal, reconfigured my new web server
and installed samba on it I have some pictures to show of the terminals.

This is of a later version of the monitor, there is an earlier version
that is almost identical on the outside. The main difference is that the
model name is "NOTIS" instead of "VDU 302 S". The only difference
I've
found in the working of the terminal is that the NOTIS terminal doesn't
have support for reverse video.
On the inside there are a couple of details.
- The earlier keyboard use an 8048 ceramic EPROM processor, Later
models have a plastic OTP 8048. Only difference on the outside is the
screws. Straight heads on earlier and philips on later.
- The earlier main board have a few wires and a piggy back mounted
chip. It also have an RC-circuit added close to the clock circuit.
- The earlier terminals use a ceramic 80186 in a socket, later
terminals use a PLCC in a socket. The pinout seems to be the same of the
sockets.
I guess that these terminals were adapted for use with the NOTIS program
set, corresponding to the office program suite today. There are a number
of non-standard keys on the keyboard, for example "regret", "copy",
"strike", "write", "help", "end"... (freely
translated from Swedish). It
contains 121 keys in total.
There is a connector for an external mouse on the back, but I haven't
seen any yet. It also looks like there is a graphic mode when the self
test is running, but I haven't found any instructions on how to turn it
on. You get to the setup menu and self test by pressing Ctrl + help
twice. Some day I'll try to reverse engineer the software to see what
else fun there is in this terminal.
The memory in the terminal is made up of 8 x 41464 (256 kbyte) so the
memory seems to be enough to support graphics.
Other IC:s on the main board:
- NEC D7220AD graphic controller
- 2 x 27512 EPROM
- KM2817A-25 2kbyte EEPROM
- 2 x Intel P82530 serial comm controller, one in socket, one soldered
- Fujitsu MB113T400, 40 pin DIL in socket.... haven't found any data
on this one, video scan generator possibly? Placed next to two crystal
oscillators, 32MHz and 36.389MHz.
- Fujitsu MB113T401, 28 pin DIL in socket... haven't found any data on
this either. Placed between the memory and the connector to the analog
board.
- 74S472 with label, 512x8 bit prom, probably character generator
- Approximately 40 more TTL and analogue IC:s
The terminal seems to be a custom adaption of a Nokia terminal for Norsk
Data AS. I also have a generic serial terminal from Nokia that is white
but the chassi seems to be cast from the same mould.
Here we have the terminal running connected to my ND-110 Satellite. The
yellowish tint is because of the white balance in my camera. The
phosphor is white as in the top and bottom of the picture.

I've got a 12 80186 in purple ceramic with
sockets. If anyone needs or
want one, let me know.
Pulled from working VT-220 compatible Nokia terminals (rebranded as Norsk
data Notis terminals).
I was offered $5 per piece from a gold refiner, but I rather sell them to
collectors.
... and before anyone start harassing me about scrapping working
terminals. I announced it here on the list two years ago when I helped a
friend clean out a storage. Of the close to 200 terminals I still have
60-70 left but I need to get it down to 20 in the end. So, they are also
available.
Which terminals are those? Models?
