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.

for the Notis programs
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.
