Thanks everyone (especially Bear) for the wonderful help in reviving my
Sun 1 Computer (100u to be exact).
After extensive CRT repairs, a EPROM reprogram (from Rev N to V100), my
Sun is now booting via the Sun2 CPU card and the bwone video board.
Will upload screenshots tomorrow!
Next step is to acquire a keyboard and mouse. Anyone have a series 1
Parallel Keyboard and mouse? Or have any ideas on what type of keyboard
or mouse would be compatible (if I was able to rewire to DB25). It
appears to be a serial protocol, are the old RJ45 keyboards of the same
format? Other ideas?
Thanks a million, you are the best!

I'd keep it as a typewriter. They're great machines.
Seconded. The Selectric (Correcting Selectric II) is my favorite typewriter. A bit too heavy to be considered
portable, but solid and great feel.
You'd need to recreate all of the drive and decode mechanism - it wouldn't be worth it unless you were
very interested in recreating a Selectric Terminal Typewriter rather than just having a printing terminal.
I'm still searching for a pdp-11/70 front panel bezel. Does anyone have a
spare? Does anyone know what the part number is for this thing? That
would be very helpful.

Hi. I've reviewed one VT220, one DEC Letterwriter and my PDP8-E. Status:
- VT220 terminal - dead (in appeareance, the tube).
- Letterwriter: PS or/and some circuitry,
- PDP-8E: working. I should like to get one Teletype for it.
If someone has some ot these items to get rid or trade, let me know
off-list. Destination, south of Europe (Spain).

Looks like the 50pin connection (J1) on the SUN2 CPU has 2 serial
ports, found a pinout:
The two serial ports on J1 are usually labelled SIO-A and SIO-B
on the back of the machine and appear as /dev/ttya and /dev/ttyb
under SunOS. The documented maximum output speed is 19200 bps.
All ports are wired DTE and are compatible with both RS-232C and
RS-423, using Zilog Z8530A dual UART chips. The pinout of J1 is:
3 TxD-A 14 DTR-A 33 DD-B
4 DB-A 15 DCD-A 34 CTS-B
5 RxD-A 22 DA-A 36 DSR-B
7 RTS-A 24 BSY-A 38 GND-B
8 DD-A 28 TxD-B 39 DTR-B
9 CTS-A 29 DB-B 40 DCD-B
11 DSR-A 30 RxD-B 47 DA-B
13 GND-A 32 RTS-B 49 BSY-B
Is the Sun 2 Keyboard a serial keyboard? If not, any ideas on where to
get a serial keyboard.
Thanks everyone!
