From: David Williams <dlw(a)trailingedge.com> Ok, I'll have to start searching and see what I can come up with. BTW, didn't someone say that I couldn't format the RD54s on here? Or maybe my mind is slipping. What other issue such as this might I encounter with the different setups? mostly correct. if you need to format a RD54 or a RD54 like drive you need either software that is hard to find or a far cheaper solution another small( 0.5cuFt) Microvax2000. Those can be found for near nothing to free if there is no disks installed and the firmware can format disks. FYI if it has 8mb or more of ram it will run VMS very nicely using a smaller disk for swaping and the eithernet for remote boot and system. Allison

Well I sometimes have some pretty good luck, maybe I'll find one If you don't your not looking. I got mine for free. The 2000 number is obviously a price for a new part. don't forget there is also EDSI and the DEC RQDX3. Of those two the RQDX3 is generally very cheap and usually free. Drives can be a problem as the RD54s are the hot item, but they are found. Allison

Reviving a MicroVAX II

by allisonp＠world.std.com

From: David Williams <dlw(a)trailingedge.com> It looks to me like the controller is going to be the more difficult to locate. I have a box of old unknown boards, some are DEC, I'll have to sort through and see if I have anything of use (either in my system or for trading) in there. Does anyone have any good sources for controllers and/or the drives online? Any suggestions on average costs? Ok, SCSI controllers are easy to find just not cheap. RXDX3 controllers for MFM disks (RD54 and friends) are fairly common and cheap. EDSI contrllers are less common but the drives are fairly cheap. It's the easiest thing to solve in VAXland.

Reviving a MicroVAX II

by dburrows＠netpath.net

Contact me off list. I have several ESDI controllers that I have been saving for the hobby users. WQESD, Dilog DQ696, etc. I even have some drives to go with them. The cheapest you will find for decent SCSI controllers are the CMD CQD220/TM (Disk and Tape). I find them on the wholesale side but the min. I have paid is $500. I typically pay $550 to $650 each even in quantity's of 10+. Normal end user prices I have seen are $735 to $1200. Keep your eyes open for Emulex UC07 and UC08. With late versions of the firmware they work nicely with CD's. The Vikings are solid but rather slow but will talk to CD's also with late firmware.

Duplicating an RSX-11M+ system disk.

Ed, Did you use the /VE option with DSC? If you can, use BRU to copy a disk. I never had any problems with disks copied with BRU.

There is no need to do this, because 2900 data books/sheets by various companies including AMD are already available in scanned format (PDF files) online. Go to http://www.freetradezone.com/ After registering you can use the Design Center section to browse and download data sheets and data books for many kinds of current and discontinued devices (including 2900 series from several manufacturers). They even have some data books from the 1970s online. Just enter 2900 or 2901 or whatever in the part number box and click the search button. That site is probably a good first place to look if you are after the data sheet for any discontinued device. -- Mark

>in getting it up and running. I want to run VMS on this, not interested in the version of BSD out there, already have enough Unix boxen. The main thing I'm missing, besides getting VMS itself are drives. This system is in the BA123 enclosure and has a TK50 tape drive.

What are my options for getting VMS for this? Any other help or comments appreciated. Ok, what you need is either a RQDX3 (M7555 hard disk controller board and a few RD54s or a SCSI card like the CMD200 and RZ56(680mb). The problem is SCSI controllers generally don't go cheap. Ideally to run VMS7.2 you need 300mb of disk(s) however smaller is possible. The SCSI board is convenient as it will allow for a CDrom needed to install from hobbiest CD. Other wise RRD40 and controller will be needed or someone that can cut TK50s from the CD. There is a hobbiest VMS license and even media available (www.decus.org). I happen to run one of these and they are fine systems for 1987 technology. Allison

This last year has been pretty miserable for me, my BBS (runs on a Commodore 64, which is my most active "classic activity") was literally down for months and ignored for a year. Tax return time did bring it back to life with a high speed modem and 20mghz accellerator, but it is still in need of programmatic overhaul to use the accellerator and my network feeds aree still stranded in Washington... :P Also my (classic computing) web pages needs updating (usually reserved for holidays but I will have to wait on that too). But I have collected lots of stuff to play with later (how many of us say that and know we have too much "stuff" and not enough "later"...) I hope in august to have available time to put more life into my classics... I must protest on the concentration of the aquiring of computers, I have had time to divide up my hobby into several categories (where the "collecting computers" bit is actually kinda small): Collecting Computers Hardware (peripherals, etc) Software Computer Books and Magazines Computing Ephemera (ads, reciepts, pins, t-shirts, games, toys, etc.) Researching (see books, magazines, above...) Reading Technical Information via Internet Contacting People related to classic computing Documenting Web Pages Articles Presentations Promoting Posting/responding in newsgroups, Maillists (like this one) Also web Ppge Running a Classic BBS or Classic Display Rambling on about how bad off the world is without good computer education in schools...

If /T(tape only), then the appropiate tape csr is required. If /M(disk only), then the appropiate disk csr must be selected. If the dual function /TM controller is enabled so that both disk and tape are supported, two CSR addresses are required, one for disk and the other for tape. If /TM is being used as a tape only or disk only, then select the single appropiate CSR. Click here for help in CSR Address selection.

Fw: X-32 boards

by dburrows＠netpath.net

The following is from a PDP11/Mass Spec customer of mine. If anyone has any ideas for him feel free to contact either of us. I will just forward anything to him if it gets posted to me or the list. With a little direction he can run diagnostics and has available an electronics shop and decent test equipment like scopes. I don't know if they have things like logic analyzers however. ( I did not need one the one time I was on site) It even meets the 10 year rule.:) Dan ---------------- We have an X-32 computer (CPU/3), a German unix machine from 1989. This computer operates a Bruker AMX-500 NMR spectrometer. The computer is functional except that Fourier transform calculations frequently give a massive "transmitter" spike that is NOT hardware related. Although we normally do all repairs through Bruker, the director of our facility does not want to repair this problem because the computer will be replaced within a year and the instrument is functional. However, for a frequent user (me), this problem is extremely frustrating and time-consuming. The problem is almost certainly one of the three following X-32 boards: CPU board H2297 ECL 12 Memory 16MB H2271 ECL 02 Array Processor H2231 ECL 06 If anyone can help with this problem, please contact me by email.

DEC CPU bulkhead issues

by Wm.King＠eng.sun.com

Chuck, Does this have a switch to select between AUI and 10-Base-2? I've recently repaired two systems where the switch was dirty and didn't make a good electrical connection. The symptoms were that the AUI port received, but wouldn't transmit. Maybe that's the problem. Bill

Paint JObs (was Re: Restoration of Discolored Plastic)

by xds_sigma7＠hotmail.com

In my IBM experience, I can personally confirm the existence of the following colors: Black (The modern standard) Blue (I have a 3262 line printer this color) Gray/grey <- this is what I think is the standard color, though the standard color depends on what line of machines we're talking about.. (My S/36 (5360), both 8100's (8140 and 8150), both 8809 MTD's, and all of my 8101 and 8102 disk drives are this color. Red (I've seen a 3380 this color) Yellow (I have a 3262 line printer in this color, yuck-o) I'm not saying that there might not be other colors, I'm just confirming that these colors do exist.

Restoration of Discolored Plastic

by dhquebbeman＠theestopinalgroup.com

Without getting the entire "Preserve vs. Restore" argument started again, has anyone ever found a way to restore the original beige color to plastic skins that have discolored due to long exposure to UV? I'm assuming what's happening is more than just the lighter elements of the plastic evaporating, but rather that some kind of chemical change is taking place that likely can't be reversed. I would think paint to not be a solution; at least not for me, as it always takes better hand/eye coordination than I can manage. How about dyes? Has anyone tried some kind of analine dye to restore beige plastic? Dyes spread more evenly and I think can even penetrate perhaps a few microns. thanks, -doug quebbeman

Where can I find 5.25 DS/DD disks?

by retro＠retrobits.com

Hello all, I have a couple of questions regarding 5.25 inch, DS/DD disks... First, where is the best place to buy some new ones? Second, does any manufacturer still produce this media, and what is the shelf life? Basically, what I'm asking here is, will our 5.25 drives become useless before too much longer? I remember a discussion on the group a while back regarding the use of HD media in DD drives. After reading about two thousand messages more complicated than quantum mechanics, I gave up trying to figure it out :-) So now I've resigned myself to seek the newest 5.25 DS/DD disks that I can find. Any help appreciated! Long live my Commodore 128! Thanks in advance, Earl Evans retro(a)retrobits.com Enjoy Retrocomputing! Join us at http://www.retrobits.com

The Original MS-DOS 4.0

by dhquebbeman＠theestopinalgroup.com

This might be a topic better posted in the alt.folklore.computers USENET group, but let me try here first. This is from memory, and it's not as reliable as I'd like it to be. IIRC, OS/2 was not Microsoft's first attempt to create a multitasking operating system. They were working on, and I believe mostly finished, a DOS 4.0 that was multitasking. This was not the PC-DOS 4.0 for IBM, nor was it the MS-DOS 4.0 that we finally saw here in the states. This multitasking DOS 4.0 (from Microsoft, not a third party) was supplied with a computer that was old only in either the UK or more widely in Europe. It seems that the first letter of the computer manufacturer was an 'A', so the machine could have been an Apricot, an Amstrad, an Acorn, or lord knows. I read about this machine either in Byte during the late 80s or in a BIX conference (I MISS BIX!). I've searched the web for references to this multitasking MS-DOS 4, and have found nothing. Does anyone else remember this? Was the Byte article reviewing a sample of a product that never shipped? Did anyone get their hands on one? Does anyone have it? -doug q

Subject: the other side of the equation - your SO/spouse

by mmcfadden＠cmh.edu

Maybe I am lucky or my SO is special but we have come to an equilibrium. She has a few pieces of sailing and tennis equipment scattered around the property and I have lots of computer stuff. Last week she was looking for the lawn swings and looked in the attic of the garage. Her first question was "Where did all of that stuff come from?" Luckily I could "honestly" answer that many of the boxes were empty waiting to ship stuff. I seem to collect really good quality computer/medical equipment shipping boxes. It's much easier to send somebody a computer if it's packed right. She has never looked in the little travel trailer which we haven't used in years. Currently full of cables and old tape stuff. I can always point to her tennis racquet stringing machine in the rec room and sails hanging in the garage. I firmly believe and we have discussed this that a computer hobby is a lot cheaper than all of the people around here who go to the gambling boats, football/baseball games, golf, or out at the bars every night. Besides I'm usually not drinking, loosing money, or chasing women just out in the garage fiddling with the computers. The skills from this hobby also means that I can usually fix a dead phone, rewire broken mixer cord, replace furnace fan motor, fix plumbing, fiddle with electrical/electronic devices, take a VCR apart and sometimes even get it back together and working. I have an old house which means all these skills are survival skills. I also get called by neighbors to look at their computers and this nets me a few old machines/components. Mike My thoughts right now, nobody else's. mmcfadden(a)cmh.edu

Your dream computer room.

by xds_sigma7＠hotmail.com

Well... It would be an entire building, I like Marvin's 10,000 sq ft. minimum, as for the fire protection, I'd for sure want halon or something similar, i.e. NO water! A raised floor of course, but with twice the normal height under the floor. Also, a basement area containing some massive transformers (so I could get 440 volt power), and diesel generators in the event of power failure. There would also be room for a water cooling system, in the event I ever get lucky enough to own an IBM 3033 or other water-cooled machine. Central air is a must, I'd require it to be a positive air flow environent, meeting mil specs. Definetly climate-controlled, I like the fireproof room for docs and software idea, also a seperate room for spare boards and misc stuff. It would have to have an area for disk pack storage too. Another seperate workshop-type room, with logic analyzer, scope, etc. Also, multiple humongous 3-phase UPS's, just in case. Hell, why not my own substation? Also, a loading dock at semi height would be good, and there would be a nice long sloped ramp too.

The cost of collecting debate

by dhquebbeman＠theestopinalgroup.com

[..snip..] > Anyway, the IBM Incompatibles that I've got include : > Sirius (Victor 9000) ??? I remember Victor going through lots of trouble before it disappeared; did it in fact get revived for a while as Sirius? Or was Sirius another company, buying V9000s and rebadging them? A Victor 9000 is one of the few PC-alikes I intend on adding to my collection; a Tandy 2000 would be another. -dq

Your dream computer room.

Will, don't stop there... why not go all the way and install a fast breeder reactor, so you'll be able to have all the electricity you need plus generate your own fuel for future use! Hey, the original post did say "Dream", didn't it? 8D

Lexmark Lexbook MB10

by ss＠allegro.com

Hi, I got my Lexmark Lexbook MB10 going finally (had to determine the polarity of the A/C input). A couple of pictures are at: http://www.allegro.com/people/sieler/lexbook/ I mention this only because there seems to be no other information on the web about this machine.

Getting into VAXing

At a former place of employment, there was a legend of one of those blasted RC25 drives crashing because someone farted. Apparently, the guy was sitting on one of those notorious un-padded wooden chairs which was on the raised floor right next to the machine (an 11/725) containing the drive. He ate lunch at the Mexican restaurant across the street. Apparently his output produced just enough vibration at just the right frequency to cause the head to hit the media during a spinup. -Dave McGuire

Xerox DayBreak

by yoda＠isr.ist.utl.pt

Hi. I have a Xerox DayBreak workstation lying on a corner back home and I'd really much liked to do something with it. I have already posted emails to this list about this subject, but since so much time passed since then I resolved to re-post to see I get something new. The issues I'd like to solve are: 1. decent interface of the display output to some monitor -- I worked on a small circuit to convert the ECL levels and separate syncs into a composite video output, for a mono monitor, using discrete components, but the image was sort of fuzzy. Are there any ideas on doing these the right way (if any)? 2. interfacing the keyboard/mouse connector to a PC's serial port -- I managed to build a decent interface for this (using a MAX232), but now the problem is protocol: anyone knows the protocol for sending key presses/releases signals? I believe they have something from 1 to 3 bytes. I have a set of PDF of scanned Xerox manuals (TechRef and IOP) including some schematics (awesome work! congrats for the one who scanned them and put them on the web!). But they don't specify the keyboard protocol. On the other hand, I also got PDF's of the MESA manuals, but they describe teh keyboard interface at the API level (no luck there either). Any help on these issues is very welcome!
