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.

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?

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

The Manchester hoard of 7090 stuff.

by peter＠vanpeborgh.eu

Guys, We have decided that the 7090 artifacts should go to the National Museum of Computing at Bletchley Park, England. Partly for patriotic reasons: the use the computer was put to in the UK. Also, we decided it is what the owner, a British pioneer of medical computing, would have wanted. Lastly, TNMOC assured me that they would be prepared to make copies availble of anything requested by outside museums and collectors. The items should be with them by the start of October 2012. It was good to discover that two complete 7090s with support documentation is available in the US and Australia. That also weighed on the decision. I do hope they will one day be reactivated, when I will be delighted to come and have a look around!

My 2/120 has six serial ports, a monochrome connector, and two RJ11 connectors on the back. One RJ11 is for the keyboard and one is for the mouse. I believe that two of the serial ports are on the CPU and four are on the SCSI controller. The keyboard and mouse serial ports are on the monochrome video board.

Sun 1 Computer LIVES!!!

Not sure of the memory, will need to look that up.

Seeing and hearing a Spitfire flying around above you adds a whole new dimension to seeing a stationary Spitfire in a museum. Recently I went with two of my sons to see the exhibition "Three tons of minicomputers - 40 years with computers in the service of Uppsala University". Both of them are very good programmers and interested in computing, and they found the exhibition very interesting. However, if the exhibits had been running, and they could have heard a line printer or an ASR-33 printing, seen and heard a disk pack seeking, seen the blinkenlights etc, it would have given them a much better idea of what computing was like 40 years ago. That wasn't possible as the exhibition was only a temporary one, but had it been permanent, I definitely agree that they should have been shown running. /Jonas

ETI Mags

by thannabus＠gmail.com

Hi there, I saw your post some where and I thought I would reply. What I am doing is "scanning" in all my electronic magazines, and saving them as *.pdf files on my hard drive. I do remember seeing a 6802 project some where, I skipped it as I am more concerned with 6502 CPU based systems. My mags are from 1977 up to 1992 and this is ETI (UK), PE and EPE. I am now coming to the end of the ETI mags. If you want that article on the 6802 CPU, I can scan it and forward it. I am not sure what sort of copy right trouble this will invite, but as no money will exchange hands, I cant see them getting upset or anything Cheers Trevor

USB keypad with FTDI RS232 chip

by Arno_1983＠gmx.de

Hi everybody, the recent talk about FTDI USB/RS232 chips reminded me of this... Sometime ago, I bought a numeric USB keypad with a two-line dot matrix LCD on top on a flea market. This piece of hardware is designated DATACOMP Electronics co., Ltd. Model No.: DLK18U_100AL and has a marking referring to "alphyra" (which seems to have been a now-defunct/absorbed e-payment outfit) above the display. It has 18 keys (4 blank, ESC (red key body), numeric keypad "0"-"9",".", backspace (left arrow), and Enter (green key body)) and shows, IIRC, "Version 1.0" on the display when powered. The .tw-based manufacturer is alive and even has a driver download for it, which seems to be nothing more than an FTDI serial port driver providing a new COM port on my computer. The FTDI chip inside the keypad is attached to an EN78P447xxx device, which I found out to be an OTP microcontroller. What I unfortunately wasn't able to find yet was any description how to talk to/what to expect from this port. Listening on the COM port at various speeds with the usual 8n1 parameters and pressing keys on the keypad yielded nothing, so there's probably some sort of initialization necessary. A long shot again I know, but if somebody has experience or documentation regarding this keypad that may be shared, then please contact me. Yours truly, Arno Kletzander

Wanted: video board for AlphaStation 200 4/233

by tothwolf＠concentric.net

I have an AlphaStation 200 4/233 which was given to me without a video board or floppy drive. I stuck an old Teac FD-235HF in the floppy bay to fill the hole (no data cable), but have no idea what I really need for a video board. I'm planning to use this machine as a low end testbed machine for Debian Linux since the Alpha port needs to be brought back up, so I know I probably need a board that can handle more than 256 colors. I think this eliminates the ZLXp-E1 (TGA 8-plane), but at the same time it may be a good idea to be able to test with a TGA board as well since there are going to be quite a few of these machines out there which have a TGA board. I will probably also want to run ULTRIX or OSF/1 on the machine at some point, assuming I can find installation media. Based on the datasheet I found online, these appear to have been (some?) of the video boards offered as options for this system: ZLXp-E1 8-plane PBXGA-AA PBXGA-AN [NT] ZLXp-E2 24-plane PBXGA-BA PBXGA-BN [NT] ZLXp-E3 24-plane PBXGA-CA PBXGA-CN [NT] ZLXp-L1 24-plane PBXGC-AA ZLXp-L2 24-plane PBXGC-BA Does anyone have an extra video board laying around that they would be willing to part with for postage costs? This machine has been sitting unused for far too long and I'd really like to put it to work.

To all with interest in IBM 7090

by peter＠vanpeborgh.eu

Guys, I am sending this to all who have registered an interest in the IBM 7090 and museums. Sorry if I got some people wrong! This computer started life at AWRE in the UK (nuclear weapons design?!) and finished in the Medical Computing department at Manchester Uni in 1970, where it ran for 10-20 years. It had 4 channels, 32K memory, card reader, card punch, 300 LPM barrel printer and ?20 mag tapes. It also had an IBM 1401 for printer I/O. I have now surveyed the stuff available. There is no hardware. It is a lot of (probably complete) hardware documentation, cicuit diagrams, s/w documentation (IBSYS, etc) also. Also a lot of mag tapes of mixed content and some card trays of mixed content. Are any of you out there interested? It is all quite heavy so transport will be a challenge, but surmountable! The stuff will be available in the first week of September. Any sensible offers will be considered. It might go on eBay but I will wait until you guys respond first.
