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! -Nick

Can a Selectric from 1961 converted in one Terminal 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.

pdp-11/70 front panel bezel

by dgriffi＠cs.csubak.edu

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. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.

Sun 1 Keyboard

by nick.allen＠comcast.net

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! -Nick
