Reading a PDP-11 RL02: Anyone Around the U.S. West Coast?

by unifoundry＠gmail.com

Greetings, I have an old PDP-11 RL02 that I would like to read, to preserve its data for archival purposes. Ideally I would like to extract and store every block on the disk. I am in southern California but would be willing to drive a day or so to anyone who still has an RL02 disk drive on a PDP-11 or VAX and can read it. I can bring a computer with X/Y/Zmodem/Kermit and RS-232 cables if that helps. Thanks, Paul Hardy

All, I'm looking for info on a George Risk 771 parallel ASCII keyboard. I've got one but no documentation or existing cabling. I'd like to interface it to my Poly-88. Thanks, Jonathan

XT/370 microcode

by spacewar＠gmail.com

As the most obvious example of the impedance mismatch between 370 architecture and 68000 microarchitecture, the 68000 is hardwired to have eight each data and address registers, not sixteen GPRs, and microcode can't easily paper over that. Similarly, the 8087 microarchitecture has hardwired support for binary floating point normalization, and microcode can't efficiently force that to do radix 16 normalization. Both problems could be surmounted (inefficiently) with enough microcode, but the chips were designed with no significant extra microcode ROM and PLA capacity.

Texas Instruments Silent 703/707 print head anyone?

by Martin.Hepperle＠MH-AeroTools.de

Hi, last weekend I cleaned and restored a TI Silent 703 printing terminal. A rather common type with its whopping 300 baud transfer rate - nevertheless a piece of history. It was easy to fix a broken trace on the keyboard PCB (corrosion) and to roughen the idler roller for better grip on the paper. Now there is one issue left: The print head is missing one dot (infinite resistance: burnt out) and one dot prints weak (resistor seems to have twice the resistance of the others, which are all around 95 Ohms). As these terminals were produced in large numbers and the printhead/ribbon cable combo was a user serviceable part someone might have some spare parts... So: if you have a new or used part #2310472-0001 printhead, thermal I would be interested. It is a 10 wire ribbon cable with the print head. It was used in the 703 and 707 and probably also in other devices of the TI 700 Silent family. Martin

by mtapley＠swri.edu

All, More of the stack. if any of this interests you please contact me via Private (not list) email at mtapley at swri.edu. If you do want something, send me your shipping address and exactly what you want. I'll get back to you with estimated shipping costs (USPS media rate where possible) as soon as I can. You send me payment (any method is acceptable; USPS does not recommend cash in the mail) and I will ship when payment arrives. If you want Fed-Ex or something different from USPS media let me know at your first contact and I will price that for you. If you can afford to send slightly more than costs, I'll collect up the surplus for Cindy and get it to her. If more than one person wants the same thing, it goes to the person sending me the earliest time-tagged email. If Al K. wants anything for Bitsavers, he gets priority (even if his is not the first email) up until it leaves my hands. There will be multiple sets of email from me, each with a short list of things, unless/until someone asks me to quit. Thanks for your attention! - Mark This list is all Software.

I note that the Kennedy incremental 7 inch reel drive in the NASA flight case hasn't attracted a lot of interest. That sample tape that I got, however does verify that the parity track on this telemetry stuff is unused. So that explains the 8 data inputs with no parity on the NASA model. --Chuck

Cray Origin 2000 From Indiana University Scaamp Project- Rescued

by phreakshowtelco＠gmail.com

I won an auction down at Indiana University for an SGI Origin 2000 System and 19 racks. Trip was an adventure. Rented a 26ft Penske Truck which was a junkheap in itself. Off we went. My gf and her best friend went along and had a blast. 7 Hour drive down from Michigan to Bloomington Indiana. In a rainstorm at dark. Waffle House outside of Indianapolis made for a very nice night. Got loaded up 9am yesterday morning. And headed home. Here are pics of the SGIs. And my gf's find an IBM Selectric II. Shes a typewriter lover. https://imgur.com/a/XzDXg Plan now is to start rounding up parts to fix it. It seems mostly cosmetic. Goal is to have it fully operational by VCFMW. I also found some historical info on it too https://www.hpcwire.com/1997/05/16/indiana-u-installs-64-node-origin2000/ Eventually this belongs on display somewhere. I plan to get an inventory of everything this week. and Im looking for any extra parts that anyone has for this. Thanks
