I'll pile on with my $0.212 (two cents plus tax). I started with a VAXStation 4000/90A. Still have it. Absorbed that system into SIMH and upgraded to a Alphastation (server?) 255. Sold that the 255 and upgraded again to my current DS10, running OpenVMS 8.3. Typing on it now in fact, ssh'ed in from $work. Luckily, I used to work for a company that had data processing services heavily invested in OpenVMS/DEC/Compaq/HP gear. I'm sure I acquired the systems over the years for well below market rates. I could probably sell the VAX 90A for a pretty large sum of $. ... but I really don't want to ... because then I'd have the money and not the VAX. :) If the power bill was free I would upgrade again .... but I have enough 24/7 equipment running in the home office. :) ... and I'm always hunting for more! (an iSeries, perhaps a Multiprise 3000, etc ... ) Fred

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

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
