I am the proud owner of a Microvax II (in addition to the 2 at work), thanks Carlos. I have it safely home, unfortunately it will be idle for a while as the garage needs to be cleaned, a bunch of construction needs to be completed before I have time to play (probably January!). Anyway I now need to find out as much info as I can about the beast. Does anyone have the link to the part number translation? Where can I get the pin outs for the card ports? Are there any docs for writing device drivers? The reason for these questions is that Carlos gave me a rather interesting board. It contains 1 68 pin DIP with TRW on it (I'm betting it's a Moto 68K chip). It also contains a bunch of TTL, DAC's and what look like op amps (I have to check the numbers). It also has an unusual RF connector but has no ROM or RAM. Any idea's? Am I going to need a scratch monkey? BTW is it easy to design boards for the Microvax. This Analog board seems really simple. Designing an intelligent SCSI board wouldn't be a lot more difficult (I didn't say anything about the Vax driver). -- Linux Home Automation Neil Cherry ncherry(a)home.net http://members.home.net/ncherry (Text only) http://meltingpot.fortunecity.com/lightsey/52 (Graphics) http://linuxha.sourceforge.net/ (SourceForge)

Given the assumption that is what you actually have, here is some info. The DS3100 will take up to 24mb of RAM using 2mb SIMMS, model no MS01-AA, part number 50-19464-02. AKAIK, that is the only memory module you can put in it. Just behind the memory is the video frame buffer. It is either a VFB02 mono, or a VFB02 color (p/n 54-19469-01). There is a mounting plate over top of the motherboard where you can mount RZ2x drives and an RX23 floppy depending on which mounting plate you have. For some other info on the DS3100 see: http://www.netbsd.org/Ports/pmax/models.html An excerpt from that site: Maximum of 24 MB RAM in 2 MB pairs (memory part number MS01-AA) 1024x864 framebuffer option module, either mono (with memory part number VFB01) or 8-bit color (with memory part number VFB02). Both provides 16x16 hardware sprite cursor SII SCSI-I controller with obscure external connector (HONDA68 male; wide SCSI-3-like, but other gender) AMD LANCE 10 Mbit Ethernet interface with switchable AUI and BNC connectors DC7085 four-port serial chip (DZ-11 clone) Two MMJ-6 serial ports, with maximum speed of 9600 baud. One port has partial modem control, the other has none. DIN-7 connector for mouse and MMJ-5 connector for keyboard. (An adaption-connector can make these ports usable as RS-232 serial ports with no modem control.) > The only other marking are BA42A... This is a SCSI expansion box for mounting RZ5x drives and various tape drives (TZ30, etc.). This box is generic enough that is usable on other DEC machines, as well as other brands. Are there any drives in the BA42, which by the way is aka SZ12 I have never heard of any other OS other than Ultrix, and according to the above URL NetBSD has been ported to it. Mike

Fwd: IBM PC Needs New Home

We have an IBM original PC that needs a new home. Below is a letter that my husband (retired IBM) sent to a local museum which declined to accept the donation.

In addition, we have all of the original documentation that was provided with the machine still in original packaging as well and floppy disks containing software. In going through our paperwork, we discovered that we also have, and would be happy to provide to you for historical purposes, the original invoice for the purchase, IBM product announcement brochures, a complete list of IBM personal computer products and retail outlets (as of 1981), details of the purchase plan, and some print-outs of BASIC programs that ran on the computer. > >To recap the history of the computer: When IBM first announced the release of personal computers early in 1981, it was clear that IBM employees would want to be among the first to purchase them. The company had a long history of employee purchase plans for its office equipment, so a program was developed for employee purchase of the new personal computers, too. Because it was anticipated that a large number of employees would want to buy PCs immediately, a lottery system was developed. All IBM employees throughout the country who wanted to be in the first group of purchasers turned in their orders in October of 1981. All orders received were then scheduled for delivery based on the outcome of the lottery. My shipment was scheduled for October of 1982, about in the middle of all of the employee deliveries for that first round of purchases. I was living in Chicago at the time I placed the order, but was transferred to Tampa effective in October of 1982, so we stopped at Compute! r La nd to pick up the computer on moving day as we were driving out of town. The next year I was transferred to Boulder and eventually retired to my present home in Mancos where the computer is now. > >I hope this information is helpful to your committee.

Who collects (reads the mailing list...?) vintage computers in Quebec, Canada?

by claudew＠sprint.ca

Hi Sometimes I think I may be the only vintage computer collector in Quebec, Canada. I would like to hear if anybody else does any collecting around here (Montreal area) I have yet to find anybody to trade or talk collecting face-to-face anywhere around here even if I have posted on several montreal newsgroups that I am looking to buy/trade this kinda stuff... When I mention I collect vintage computers, people look at me like I am due for a trip in the "wacko wagon"... Computers are tough to find here (not like california...) I have managed to accumulate/fix/restore approx 50 micros (all working) from the 197x-198x early 1990's...lotta books, software and peripherals... Those who feel sad for me can send me their Lisa's, TRS model IIIs and Next boxes ;-> ...things I will probably never find around here and I refuse to purchase them on ebay for a zillion bucks... Thanks for reading Claude

I need PDP-11/34A Help Again (Suprise Suprise)

by univac2＠earthlink.net

First off, I'd like to thank you for all the help you have given me. I had to take a break from the PDP-11/34 for a while, but I'm back now. I think the computer is working OK now, but I still can't get the printout on the console. I double checked the settings on the DL11-W. When I turn on the computer, the RUN light flashes for a split second, and the readout reads 000002. How do I examine and deposit? I'm using a LINK terminal emulating a VT-100. I set all the communication settings to match the DL11-W, but what do I do with these settings: Main Rcv Hndsk Main Xmt Hndsk Main Rcv Level Ignore 8th Bit Communications Mode Disconnect I've tried this with a Null Modem Adapter, and without. Any ideas? Thanks, Owen

And it's been almost 10 years now, so I may be > misremembering the whole thing. Well my recent (last night) experience suggests that what you remember is true. I was refitting my BA123 with a CPU, 8Mb of PMI memory, my one-and- only DEQNA and an RQDX3 and stuffed into it a bootable RD54 from a VS2000 that happens to have VMS 5.5 and some stuff to fire up a LAT server and clustering. The startup bitched mightily about the presence of the DEQNA and casual reading of the error messages seemed to tell me that VMS 5.5 cluster manager did *not* like it one bit. Because the machine is standalone at the moment, I didn't pay much attention to it all. Eventually, I do need to get something working with Qbus and Ethernet (so I can begin to make physical backups of some 9 track tapes I have sitting here). I'll have to either stuff a KDA50 in this beast and use my MDA SDI<->ESDI box (dual 1.2Mb disks) or hang a couple of RD53s off the RQDX3 and limit myself to one or two tapes at a time before shooting them down the pipe. Ah the good old days... -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

R.F. Interference (Was 48V)
