Data General software agreement pre-announcement (Merry Christmas)

by bruce＠Wild-Hare.com

Data General legacy preservation fans - After 9+ years of negotiations, Wild Hare has secured an agreement with Data General to recover, archive and release Data General 16-bit and some 32-bit software for educational and non-commercial purposes. A official announcement will be made next month, but I wanted to let list members know that sometimes good things can happen. A special thanks is extended to the amazing William Donzelli, and to the quick-footed Carl Friend, who made the physical tape rescue in Massachusetts possible. Thanks also to the legal and technical folk at EMC (Data General) who finally made this a legal reality - and who might prefer annonymity at this point. Details will be posted in a few weeks, but I wanted to share this bit of Merry Christmas for DG fans.

IBM RT-PC available

by snhirsch＠gmail.com

All, In my ongoing effort at clearing space, I must part with my beloved IBM RT-PC. This is a desktop form-factor with the "enhanced advanced CPU" (don't you love 80s marketing-speak) running at a stunning 16Mhz. with 8MB of memory on-board. I have upgraded it with a 1GB ATA drive and an Adaptec SCSI adapter and it's currently loaded with AOS / BSD 4.4. Has ethernet adapter and was in-use on my own network. Other items: - A bookshelf or two of documentation - One or two of every expansion card ever made for the unit - Extra mouse and keyboard (non-standard connectors) - Multi-Port serial card for POS systems (?) - Complete software distribution of AIX 2.x - Complete AOS / BSD 4.3 - The semi-mythical BSD 4.4 port w/ sources - A couple of ESDI drives (original hard disk) - The "academic" OS high-resolution grey-scale monitor w/ video adapter. This supports X10 R-something under AOS. And probably many, many other goodies that slipped my mind. I'm open to negotiation on price, but the kicker is: You Gotta Come And Get It. There's enough stuff to fill the back of a small van and I'm not even going to address shipment. I'm located in Burlington, VT. Please, someone give this a nice home? Steve --

PDP-11/34A acquistion and questions -

I recently rescued the following system: One full size (H960)rack cabinet containing (from the top down) - DEC PDP-11 crest Telebyte TDX 1/2" tape drive PDP-11/34A w/ full programmer's console Data Systems Design (DSD) 880-120 homebrew connector panel Wesperline I/O unit One "corporate highboy" cabinet (VAX style) RLO2 drive BA11-KE chassis non-racked items - 2nd RLO2 drive DSD twin floppy system, 110/430 additionally - 8 disk packs + "pack rack" several boxes of 8" floppies, including an install set for RT-11 V5.1c, configured by Cambridge Digital, dated 1984 card inventory (by chassis slot) - - 11/34A (chassis marked 11/34A XX) (1) M8266 control module (KD11-EA) (2) M8265 datapath module (KD11-EA) (3) M8267 floating point (FP-11A) (4) M7859 programmer cons (KY11-LB) (5) M8268 cache board (KK11-A) (6) M7801 data word cntrl (MC11) [I think I must have misread the card number and this is really M7891, 128KW MOS RAM, but I haven't yet verified that] (9)<->(11) M9202 backplane jumper (12)DSD 808830 controller for DSD 880-120 (13)DILOG DU130 tape controller (14)M7865) SLU+RTC (DL11-W) - BA-11-KE (3) M7860 parallel I/O (DR11-C) (5)&(6) MSP-3/A, MSP-3/C Computer Design Assoc. boards (8) M7762 RL02 disk controller (RL11) (9)<->(11) M9202 backplane jumper (12)&(13) MDP-3/M CDA boards (includes 4 AMD 2903 SuperSlice chips) Pictures at: http://tinyurl.com/pdp1134a ************************* The system was apparently used for data logging and analysis in a windtunnel application. Questions: 1) Can anyone provide more info on the Computer Design Associates board sets? Each of the board sets is comprised of two boards in adjoining slots with ribbon cables across the board tops. I've emailed the researcher who used this system in the early '80s but haven't heard back from him yet. 2) Are there PDP8 device interfaces for either the DSD430 or DSD880? The 430 emulates a pair of RX02's; the 880 emulates an RX02 + RL02 and is capable of formatting floppy disks in stand-alone mode. From the bitsavers manuals, I see that there is a PDP8 interface (DSD 2131) for the 210 and 440 chassis, but it's not clear if there were similar interfaces for the other units or if the 2131 will support the 430 chassis. Thanks for any help, Jack

Apple monitors

by brianlanning＠gmail.com

So it appears that not all apple monitors are created equal. I have a 17" apple monitor from a mac that I tried to attach to an Apple 2gs. They're all db-15, but this combo didn't work. Is it a frequency range thing? Is there an easy way to get this to work? The 9" 2gs monitor is a bit small. brian

CNC/NC

If I remember right the series 2 used stepper motors. One set of coils faulty? But on Y and Z seems strange. Maybe there's something in common for the coils of both axes. Rather less likely but the (woodruff?) drive keys could have sheared, but again on both axes at once seems unlikely. Do the motors turn or just go a tiny bit backward and forwards? Of course its possible one of the axes could have failed earlier and the machine used for simpler jobs. I once made a CNC program (prepared on the Apple 2) to machine elliptical valves (upside down poppet valves) and the program only used X and Y axes. Similar jobs must exist.

1Mx4 DRAM DIPs

by keithvz＠verizon.net

Hi, This is my annual 1Mx4 DRAM memory chip post. I'm looking for some old DRAM memory chips with the following specs: 20-pin DIP memory chips (16) 1meg x 4-bit dips make up a bank of 8mb. Should be 60-ns Fast Page Mode non-parity An example would be Toshiba TC514400AP-60. Other manufacturers might use the following base part numbers: Fujitsu MB : 814400 Goldstar GM : 71C4400 Hitachi HM : 514400 Hyundai HY : 514400 Micron MT : 4C4001 Mitsubishi M5M: 44400 I have some in surface mount (in a goofy 26/20 format), but without small PCBs to convert, they aren't much use. There are some out there in SOJ, also not useful. Yes, I know some old video cards might have them, and yes, I know the Epson ActionLaser 1500's have them. I haven't found a single source in a couple years. There are some companies, like usbid.com, that have them. All of these companies have $250-$500 minimum purchases, and I really don't need that many of them. Or want to pay that much. The form factor is important, but if I can only get EDO and 80ns, I'll take those too. :) Thanks and Merry Christmas. Keith
