Marquette "MUSE"--DEC mini/file server circa 1986-88

by ip500＠roanoke.infi.net

Anyone know anything about the above captioned computer??? It's a beast! Big HEAVY! upright tower system 27" tall X 27" deep with a HUGE power transformer in the bottom of the case. Model D171. Main components are DEC Backplane marked "H9275A", processor card "M8192" bunch of other non-DEC cards in there as well--SIGMA, EMULEX, couple of unmarked ones. Powers up, HD blinks, has a built in tape drive. Did a search for Marquette and they are now GE/Marquette--medical/EKG,EEG monitoring stuff. Is this some sort of rebadged DEC system or a totally custom ie: worthless medical gadget....looks promising. Thanks, Craig

Yes, DEC did: ZY003P3 Field Service Tests disks for the microPDP-11 series, contains 4 Field Service Test RX50's (CZXDnB0 where n = 1...4) and a CZUFB1 disk which has the monitor, menu, help text, UPD2 and assorted tests including ZRQA?? and ZRQC?? I've also got a pair of rather later XXDP 2 disks from 11/53 systems, which have XXDPXM, XXDPSM, DRSXM, DRSSM, DIR, assorted drivers, UPDAT, XTECO, DXCL, SETUP, HELP. One disk also has ZRQA??..ZRQF?? and the other has VDHA??..VDHE??, VMSA??, ZTKA?? and ZTKB?? -- Pete Peter Turnbull Dept. of Computer Science University of York

8-bit IDE

P2dos, Novados, SuprBDOS all support files to 32mb and drives to 1gb. BUT, the logical drive to physical drive map does not have to be static. For example you could only have drives C/D/E/F as mapped to 8mb logical drives. Drive C: could be partition 1 and a fixed mapping. Drives D/E/F could be mapped to floating partitions anywhere on a very large drive. I supported two 71mb MFM drives this way back in 87 under CP/M2.2. >handle that much. Back when I used CP/M every day, I owned the largest hard >disk system on CP/M that I'd ever seen, at 44MB. Obviously you've never seen many of the systems I ran or have aquired. Likely the 44mb limit was based on inavailability of really large drives. Even my AmproLB has a 45mb SCSI on it and I plan to bump that up to a 160mb. The current system I'm building I'm planning will have IDE 250mb drive. Space is handy as I can have a 8mb partition for pascal and another for C or whatever. >notebook drives should cost about $5-10, which is acceptable. Clearly, There are plenty for under 25$. Though you have to decide on 9.5mm, 12mm or 17mm thick models. Allison

RRD40 terminator?

by cmcmanis＠freegate.com

Hello all, I've got an interface to an RRD40 in my VAX called a KRQ50 and it has two "ports". One connects to the RRD40 with a 15 pin or so cable, the other, I don't know. Then in the box of stuff that went with this is a terminator (green LED on the back) with the same D-shell connector as the RRD40. So I'm trying to figure out whether or not they went together. I've never seen such a terminator before. --Chuck

Do you just want the RQDX3 utilities on it? Up until a year or two ago, DEC would sell you a subset of XXDP on RX50's that included the things commonly used on Micro-PDP's. They don't have any RX50's left in inventory, though. >BTW-- Are RL02's a maintainance nightmare? Do the advantages >of these drives outweigh the problems (not to mention their *size*, >or are they simply not worth it? RL02's are, IMHO, the most reliable of all the 14" removable cartridge drives. The embedded servo design means that absolute positioning alignment does't have to be done. (Though the relative alignment of the two heads does matter somewhat.) The head flies pretty high over the platter, so crashes are rare. I know one site that ran a bunch of RL01's (mechanically very similar) continuously for twenty years before upgrading to RL02's, and the only problems they had were the spindle bearings wearing out. And they aren't very big or heavy either. They're less than 70 lbs each, so they're easy to move around. The big Massbus drives, those are a different story. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Guys: Has anybody ever ripped the Low Level formatter >from the XXDP+ diskpack and put the needed components onto a floppy (of some sort)? I'm contemplating attempting to do this myself, but in case it's been done already, I'd just as soon as not re-invent the wheel. I'll need the formatter used with the RQDX3.

PS/2 memory

by PeksaDO＠Cardiff.ac.uk

Speaking of PS/2 memory, can anyone shed any light on the following MCA memory card: Made by Quadram. There are various stickers: [908503] [02790487][REV 1B] [K.B.] [9080R1] [9081R1] [9079R2] The [908503] sticker obscures an etch number 17-9085-[908503]R1 There are four 30pin SIMM slots furthest from the back plate, each containing a 1Mbyte SIMM. I've searched the web but can't find any info. There are three 3pin jumpers (marked J1, J2, J3) and one toggle switch on the back plate. I've assumed that the jumpers set the starting address/size and that the toggle switches it off and on but can't see any extra memory (even after trying various combinations) in my PS/2 model 80.

8-bit IDE

>As it happens, the committee did standardize on the one mode bit that makes >the interface an 8-bitter. How extensively that was adhered to remains to >be seen, I guess. Well wishful thinking had me check it out using several 85-130mb drives (quantum, Seagate, maxtor, WD) and none seem to do that. After all having that would make the interface a no brainer and save a simple silo for splitting read and writes. However, it was wishful thinking. As to doing it on S100, been there done that. the interface logic needed to do the bus does 3/4s of the work and it only needs a bit more the close the loop. CPLD/FPGA/PAL could cover most of that but for S100 I like real TTL (244/241/373) like parts and NO cmos where the bis interface occurs. Allison

Is the cheapness of IDE drives worth all the heartache of the cable length and funny line driver limitations? The cable length limitations are so short that you've almost got to put the hard drive in the same box as the CPU - this isn't good if you want expandable or flexible systems! But if "cheap" is the main requirement, I suppose it's OK. Maybe I'm too used to dealing with systems where the hard drive might be 60 or 100 feet away from the CPU... (differential SCSI and SMD.)

by CLASSICCMP＠trailing-edge.com

> Is this some sort of rebadged DEC system or a totally custom >ie: worthless medical gadget....looks promising. It's a system, with DEC CPU, non-DEC controllers/peripherals and a non-DEC backplane/chassis/power supply. Not too unusual - IMHO it's *more* unusual to find an entirely-DEC system. Note that it is possible to assemble a brand-new PDP-11 "compatible" using no DEC parts at all. For instance, I know of one desktop system using a Mentec M11 CPU (totally custom implementation, not even a J11), Andromeda SCDC SCSI host adapter, Logical Company async multiplexer, and a Seagate SCSI hard drive in an Andromeda desktop Q-bus enclosure.

I have 2 excess 4033-001 print servers with manual and power supply to find a new home for. Will trade for more common PC stuff that I can use or ethernet items. Will also consider offers for cash. Not too heavy, about 3 lbs each so shippingmost anywhere shoudln't be a biggie. No cable though, you need to supply either a DB9 to RJ45 media filter or the normal DB9 to IBM data connector whip to use them, dependant on your needs.

CPU upgrades, pt. II

by allisonp＠world.std.com

Nope, SCSI to the rescue. I use MCS 700 future domain in my 70 bought used from C.R. when I was in US visiting my friend. Actually a cheaper way... Parallel port adaptor. It's how I run Win3.1 on that one without loading the disk that on it (currently only dos on it). Should work in your 50z but needs 386 level to work according to DB Young and shove in more ram while you are at it. True. The problem with that machine is common to most 286s, there's enough perfomance to make use of it but, not enough ram, disk and it's not 386. So in the end I can easily run dos/lanman/IP with windows 3.1 but, only dos apps will fit in the available ram. I have an INboard386 PC in a leading edge. Same problem more or less. I do have a 386/16 with that and 1meg of ram but 4-5mb is needed to run windows apps of any value. I plan to try minix in that beast as it would leave enough uesful ram for a IP stack. Allison

I've got some -10 code which it executes built into the program so I can test instruction speed... about 500k eips (emulated instructions per second) on a 6x86... I'm basing mine on Bob Supnik's simulation control package, which is really nice in itself.

Research Machines Link 480Z

by flo＠rdel.co.uk

I've just obtained an RML 480Z. This machine was commonly in use in schools in the UK during the 80s, as an alternative to BBCs or Spectrums under a government initiative to keep our computer industry alive. Unfortunately, there are no cables or documentation with it. It has a large array of DIN sockets at the back for cassette, two monitor connections, and two serial ports. Does anyone have the pinouts for these sockets? I'll email Research Machines as well to see if I can obtain any documentation, but the only reference to 480Z on their web site is on the Y2K page, where it says that they don't have a real-time clock.

Nov 1976 Interface Age magazine

by paulrsm＠ameritech.net

Does anyone have the November 1976 issue of Interface Age magazine? There is an article by Steve Wozniak publishing 6502 floating point routines. I have the August 1976 Dr. Dobb's Journal with the same or similar information. I want a copy of the Interface Age article so I can compare the two.

by mgregory＠vantageresearch.com

Hi Pete, I can't help with your question, but you may want to post it on comp.sys.ibm.ps2.hardware. There are a lot of extremely knowledgeable (if not fanatical) MCA enthusiasts there (notably Peter Wendt, Louis Ohland, and Bruce Lane) and the signal to noise ratio is high. The group helped me a lot in reviving a PS/2 Model 8595 server last year.

CPU upgrades, pt. II

by peter.pachla＠wintermute.org.uk

Anyone come across an "XTEND MICROPRODUCTS" processor upgrade card for MCA machines? I've found one inside my PS/2 Model 50, which I was previously unable to identify as the markings on the PCBs are hidden inside the "sandwich" IYKWIM. Anyway, it appears to replace the onboard '286(?) with a '486SLC (no real clues as to clock speed, but could be 25MHz) and has a socket next to the processor which I'm assuming is for a math co-processor? Would I be correct in assuming that the system will not start up if the 72-pin SIMM sockets on the upgrade board are empty....I've never gotten very far with this machine as I don't have any 72-pin SIMMs to try in it?

New stuff and lots of Digital help

by dogas＠leading.net

Hi all, I knew that hanging aound you nuts wouldn't be good for my computer collecting dementia. ( reference http://users.leading.net/~dogas/COMPOSITE.jpg ) Until recently, I've kinda resisted adding Dec equipment due to storage concerns. Until recently... So, here's my digital stuff... http://users.leading.net/~dogas/classiccmp/digital/digital.htm ...that I can use some help with... 1. I've got an 11/05 missing a KD-11B processor board #1 (M7260) 2. I have no space currently for the 11/44 and MicroVax 3600 and will entertain any 'hosting' options 3. My MicroVax II is booting into Ultrix 4.5 and I'd rather learn VMS 4. I'm need a mouse and monitor cable for a VaxStation 3100. 5. One of my Heathkit H-27 floppies is broken and I also need an os for it. Any suggentions for any of the above problems would be appreciated. In the meantime, back to the classiccmp archives. Hey, I also found two Honeywell 316 minicomputers too, check out... http://users.leading.net/~dogas/classiccmp/h316/h316.htm Cheers. - Mike: dogas(a)leading.net

Lubing Shugart 800,801's?

by allisonp＠world.std.com

First item,, I've seen lots of 800/810s with lube on the leadscrew from the factory. Two, carb cleaner is toxic and usually bad for most plastics. My cut is pull the lead screw/stepper and properly clean it and lube very lightly with good molly grease. >that is available to you, then lubing it with a LIGHT coat of (one drop for >every three drives) of WD40, then adding about 1/4 tsp of moly-disulfide, WD40 is penetrant and evaporates very quicly leaving mostly nothing. After your done cleaning any know good disk will suffice for alignment. I've even eyeballed them in. the tracks are really quite wide! Allison

Complete List Archives Available!

by af-list＠wfi-inc.com

Hi, I know Kevan indicated recently that he was in the process of rebuilding his archives, and I'm not sure of the current status of that, but in the meantime I've put up all archives since March of 1997 (start of the list) at http://www.retrobytes.org. I can't express how many times his archives saved me and I just wanted to get that information back up for the public as soon as possible. I was a little shocked when I sent the U Washington Listproc server an "index" command and found that they still had all of the list archives available! Another thing that amazed me was how *prolific* this list has been in the past. One month (April 1999) was just shy of *3000* messages! I haven't totaled everything, but I would easily guess that there's upwards of 50,000 messages for the last three years. What an unbelievable technical resource! I think there was a comment about the volume of messages that Tony Duell posts; if you have any doubt, look through any of the months by Author to see just *how much* he contributes here. One of the things I'm considering is making a CD-rom distribution of the list archives available to list members; any interest? It would allow for faster searching and accessability to the archives for someone working on a classic system not in the immediate vicinity of an internettable computer. I could make it available as an ISO image download by individual request, or burn CD's here for the cost of media/shipping. I still need to add the search capability, so I'm seriously looking for someone with experience setting up Glimpse or something similar. Also, any ideas for setting this up for a CD version would be appreciated. Cheers, Aaron Special thanks to Hans Franke for supplying me with his saved archives, before I knew about UWash's listproc archive...

A New Find

by jrkeys＠concentric.net

The other day I was given a Sym model 1 in a custom case of black metal with wooden sides and a built in keyboard sold by Synertek. There small wooden door on top that lifts off to view the on board LED and KB. This system has been upgraded with extra memory and other features. He also gave all the documentation for it and some newsletters from an old Sym computer club that used to be at Honeywell. The board is dated 1978 with SN 3433. It will be a great addition to my collection and I hope to fire it up soon.
