CP/M for AES 7100/Lanier Dedicated Word Processor ???

by claudew＠videotron.ca

Hi I picked up one of these AES/Lanier 7100 a few weeks ago. It's in near perfect shape and boots to what looks like a word processor. The WP software thats in there right now is on 5 1/4 hard sector disks... I have heard rumors that a version of CP/M was available for this machine. Anyone ever heard or seen this or would by any chance have a copy? Claude Canuk Computer Collector http://computer_collector.tripod.com

I make sure I mark one of the corners and one edge of the layout exactly in registration on both layers. When I expose the PCB, I make sure the raw PCB is exactly lined up on that corner and edge for both exposures (both sides). It helps if the raw PCB is carefully cut! Transfer paper might actually be easier if oyu can do both sides at once, but you'd have to make sure it didn't stretch or warp. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

VaxStation 2000 PSU info needed

by ajp166＠bellatlantic.net

To start with the switcher in question is 1987 design maybe earlier. The MV2000 was available in 87 or 88 if memory serves. And even if I'm wrong it's very definatly pre1990. Dec often used standardized designs for years despite technology. Regarding you comment on rotating technology.. your wrong. The biggest problem is that often the older technologies were kept available too long or in service too long. Add to that usually at least 50% of the rotating memory was not even DEC to start with. Look at the DEC designed products. Allison ------Original Message------ From: "Richard Erlacher" <edick(a)idcomm.com> To: classiccmp(a)classiccmp.org Sent: April 16, 2001 3:03:26 AM GMT Subject: Re: VaxStation 2000 PSU info needed Back in the early '80's it wasn't uncommon for switchers to malfunction, or, if designed somewhat better, to fail to function at all, if no load was present. This is consistent with DEC's practice of putting out 10-year old technology in its "current" products. Their rotating memory products were always at least one, and often three, generations behind the "current" generation in other makers' products. That ensured maximal profits for DEC shareholders and maximal bonuses for their execs, though it also ensured last-generation performance or less for their users.

NeXT Cube Computer Back Cover

by reyes＠orion.ae.utexas.edu

I have a NeXT Computer cube. On the back of the Cube it has a NeXT logo and under the logo is in bold "Computer". I was told that some cubes have instead of "Computer" either "Cube" or "Turbo". Is this true? Did the text on the back of the NeXT cube change over time? Can anybody point out any other differences on the back cover of the NeXT cube. Reuben

Kim / Commie keypads

by ajp166＠bellatlantic.net

Foo, mine was used, is used and works. It was dirty enough to require a trip through the dishwasher though. It wasn't to hard to open and wipe the contacts afterwards. The RS pad (special catalog item likely not their manufacuture) would work as would many others. Maybe I'm just more resorceful that others. Either that or rather that grouse about it I just do it. Allison ------Original Message------ From: "Richard Erlacher" <edick(a)idcomm.com> To: classiccmp(a)classiccmp.org Sent: April 16, 2001 2:14:29 AM GMT Subject: Re: Kim / Commie keypads Well, in that case, since the user manual is posted at the URL included in the original post, and you'll see it's not the "usual" scanning matrix being a 7x3 or some other obtuse pattern, and not easily physically replaced with a run-of-the mill matrix keypad. Since you have a KIM-1, you know what the size is, and you know what the Radio Shack product is. If the RS product would fit in place of the original perhaps you could indicate that. If your keypad is still working, it's clear you haven't used it much. Just let us know ... don't equivocate. Putting a Radio Shack product on a KIM-1 kind-of makes my skin crawl, but if it will fit closely as a replacement for the original, and if that's what's wanted, why not? The designers did provide access to the scanning inputs, however, so an external and much more comfortable and durable keypad could be put in place with little hassle. If the desired solution is to use a serious keypad the externally applied replacement can be of whatever size is desired. It occurred to me over the Easter dinner at Mom's that one could use the top segment of the capacitive switches by situating them over a perfboard with wire leads soldered to it. The somewhat conductive pad on the lower surface of the key will close the circuit just fine if a bit of aluminum foil is rubber-cemented to its conductive surface. If it seems I don't know what sort of switches are in a PC keyboard, that's because I don't, BTW. The only PC-targeted keyboard I've disassembled has been that MicroSwitch model. That should, however, make the surplus PC-keyboard's switches useable. They're mechanically and ergonomically decent enough.

VaxStation 2000 PSU info needed

From: Richard Erlacher <edick(a)idcomm.com> >I snagged a VaxStation 2000 box some time back, mainly for the PSU. It turns >out that it has a couple of lines, on the 9-pin MOLEX main power output >connector, the purpose of which is not clear. There's one that seems to float ///snippage//// I have three working plus a TK50 in an external box (same box), if that isn't enough I must have 6 or so of the PSUs that I use for "projects". The PSU wants a 10W load minimum on both the +5 and +12. It's rated 160W OUTPUT. It easily runs a P166 with options. The +12 is heafty enough to run a MAXTOR2190 with reserve figure it for not less than 4A. The remainder is on the +5, If memory serves it's good for 12A++. The minus voltages are for RS232 type use figure them for .5A. The "floating line" is powerfail and is open collector. I rarely use it. Have fun

The rear one is not bad but the front one does involve some alignment. Again I have not taken the time. I did try lubricating the top bearings with a syringe and still had problems. I then removed it and did the bottom bearing. It ran free then but I had alignment problems and no alignment tape or info. At that point even with over a dozen drives on the way to scrap metal it was not worth any more time to me. Dan

I could be wrong there though. OS/278 is on uu.se archive if memory works. thats the only other I know of other than PS/8 which is the realtime version of OS/8 and that would take work to run on DECmate. There may be others, I can't be certain. On the other hand writing an OS for PDP-8 would be interesting as the reatime monitor and such are all around as source. Allison

Not exactly. I've several monetary offers in-hand for analyses for when I finish getting it connected to the microscope. As far as I can tell Kevex shipped analyzers in this configuration until just a couple of years ago. Now their newer products are based around a Windows PeeCee that takes over twice as long to run a spectral analysis on a sample as their previous [J11 and embedded Z8000] design did. > Do you have any non-DEC > boards? What is the interface between the PDP-11 and the microscope? I have tons of them. I assume you mean in the Kevex analyzer. ;) The analyzer consists of a KDJ11 board, a third-party disk controller board, a graphics board, and a bunch of parallel I/O ports. It connects to a custom backplane containing an embedded Z8000 data cruncher, which in turn connects to a NIM bin which contains the analog front-end and detector interface and the A/D converter stuff. The detector attaches to the rear of the microscope chamber in an accessory port. > How does RT-11 perform? Are there any enhancements that you could use > at this point? It performs wonderfully. The only thing I'd like better is if it [the control software] were networkable, but since most of it talks directly to the graphics board in the qbus backplane, I doubt that'd be a likely hack candidate. The unit isn't old enough to be able to get the source out of Kevex for hobbyist use, since it's still a supported model. -Dave McGuire

It is but look at the EIA line there and its name and function. Different name is the problem. It was used for HALFduplex modems to arbitrate flow. The DEC parlance prefered the three wire signaling with signal common and TXD and RXD using xon/xoff flow control. If the connection was used with wider signals then DTR/CTS were added to signal mostly that something was connected. Allison

Ya know, I really dislike TK50 drives...

by dburrows＠netpath.net

Welcome to TK50 terrorism. The only thing now is to rewind manually. I typically use a battery drill with a Phillips bit. You will find a hole in the center of the PCB directly under the cartridge that exposes a Phillips screw. This is the cartridge drive spindle. On slow speed rewind it back into the cart. with the drill. What did you in are the sensors on the 2 tape rollers. If either of the rollers stick in either direction the drive decides it does not know where on the tape it is and shuts down. I use a marker on the top of the rollers to determine which roller is causing the problem. Then just watch the marks while loading a tape. Don't feel bad - I have gone through over a dozen drives to get good ones and the biggest cause failure are those roller bearings.

Is this machine one the > large heavy ones I've seen in older books or have they brought the > electromicrograph machines to a reasonable size? I'd hate to even ask what > one surplus would set a person back. They're all large and heavy. Because semiconductor and computer technology shrinks constantly, there's a natural assumption that everything else does too, and thus anything that's large is ancient. There's really no way to shrink the vacuum valves, pumps, high-voltage power supplies, and stuff like that...what does shrink is the control electronics, but that's really all. Generally speaking, there have been NO applicable significant advances in the major technologies that make SEMs work in the past 30 years...electron beam generation, acceleration, and steering, vacuum chamber control, phosphorescent electron->photon conversion, and high-speed scintillation detection. Until fairly recently, all new SEMs had huge panels of lights, switches, and knobs. Nowadays manufacturers are shipping SEMs with a power switch and a PeeCee running Windows that does everything between crashes. The average scientist hasn't really embraced this approach, so there's a huge business building around maintaining older-style manual-control SEMs. My SEM does happen to be pretty old, but not too old as SEMs go. It was made in 1981. I have been in contact with the guy who had maintained it under a service contract at its previous installation. He is a former employee of the company that manufactured the unit. He runs a fairly tidy business maintaining only this make and model of SEM within driving distance (he's north of me in Southern PA), he maintains fifty or sixty of them...indicating that a significant number of these 20-year-old instruments are still in service. For your SEM hunting information, count on about a ten-to-one age ratio compared to computer hardware...a 20-year-old SEM would be approximately comparable to a 2-year-old computer. > Maybe Dave can get a photo of his stuff in place and put it in the image > library as well for use to take a look at.

PDP-11/24 -- BA11-A help needed

by dburrows＠netpath.net

>Is there anyone here with experience working on a PDP-11/24 in a BA11-A >box?? I am trying to more mine from a broken BA11-L to a working BA11-A >and I need some help with where one of the cables from the control panel >goes. > >Anyone?? > >bill One goes to the CPU backplane and the other goes to the power supply. The power supply connector is kind of hidden. You will need to slide the supply out about 1.5 inches in order to see it. I hope you are using a BA11-A that has the H7140-AA (IIRC) in it. IIRC the H7140-CA is only for expansion chassis. IIRC the -CA has only +5 and +/-15v. The -AA has +5, -5, +/-12v, +/- 15 Also be careful using backplanes from expansion boxes in the CPU box of the 11/24. They often have some jumpers on the supply lines ( soldered where the supply wires meet the backplane) that short the 2 sets of +/- supplies. A while back I scanned some stuff that may help you. Poke around ftp://zane.brouhaha.com I am sorry but most of the originals have been destroyed by a fire 2 months ago. Not to mention a LOT of PDP11 equipment at the same time. Dan

Ya know, I really dislike TK50 drives...

by cmcmanis＠mcmanis.com

Well in classic style I was restoring a MicroVAX II (and this one is a true classic as its in the BA23 pedestal case and everything). It is still missing a couple of bits (like the brackets that keep the BA23 in side the plastic area of which it has only one, apparently its previous owner liked being able to pull out and re-insert the BA23.) So it also has a TK50 and I took it apart, blew out the dust checked it over, and even loaded a test tape (had standalone backup on it) and booted it and removed it. Great, a working TK50. So I put what alleges to be a Ultrix 2.2 install tape, and boot that. It boots! Yippee, and then rewinds the tape (I've got no idea how to install Ultrix and typing 'install.1' got me a screen that said "no devices to install on" :-(. So I figure it should at least see the tape and I look back at the TK50 and it thinks its unloaded (green light on, red light off) I pull the handle up and the red light comes back on, cartridge comes half way out. I know that the solenoid has re-engaged for some reason so I push the cart back in and do the unload fan-dang-go (you know push the putton in and out, per the manual, six times) whiz, whirr, whiz, whirr, ka-chunk. Green light comes on. I pull the handle and the red light comes on again. So shut everything off, pull the tape unit, remove the cover and 1/2 of the tape is still on the take-up reel! So this is a new failure condition I've not yet met, and I'd really, really like to keep this tape. So does _anyone_ know of a way to "force" the motor under the cartridge to rewind? A test point would be great but even just "put 12v across it here and here and off it goes" would be doable. I'm willing to sacrifice the drive to save the tape but don't want to if I don't need to. Perhaps a signal pin on the conecctor? (I've yet to find a pinout for this connector in my docs or a schematic of the M7546 (TQK50)). Sigh, --Chuck

My Collection

Yes, two of my systems run RT-11 (V4.00 and 5.01). One 11/73 normally runs RSX-11M (4.2). The 11/83 runs BSD 2.11, and an 11/23 runs 7th Edition UNIX. The Microvax runs VMS, or at least, that's what's on the disks and I will figure out how to make it do things one day, honest. I also have various versions of XXDP on 5.25" and 8" floppies, and an RL02 pack. I'm not quite sure what I have for the VT78 as it's been in storage since I got it and I can't find the disks right now. David Gesswein has been helpful in pointing me to some software, and I expect I'll end up installing something something liek OS/8 or OS/278. The SGI machines mostly run IRIX 5.3 (one Indy has 6.5), and several of them have applications software (like MediaMail, Netscape, Acrobat Reader, ..) which I use regularly. One of them is the local mail server and fileserver, an also acts as a modem server for some home-grown viewdata software; one manages the print queues. The one with the modem is likely to have HylaFAX added to it (fax server software). Two of them are the machines my wife and I use for most day-to-day stuff. The other machines that get used regularly are an Acorn Archimedes A440, used as a fax server and DTP machine, using ArcFax and Impression Publisher, One R260 does a similar job at work, where it's used to print CD-R labels -- Publisher again -- and also acts as a terminal emulator to connect to serial ports on hubs and switches. There's a boring PC that gets used to decode Word documents sometimes, if the SGIs' can't read them, and occasionally to use Powerpoint, and sometimes to run some network management software for fun. The Exidy Sorcerer and one of the BBC Micros are sometimes used for games. I have a pretty good collection for the Beeb, including classics like Elite, and Revs; not much for the Sorcerer except Galaxians and Breakout. Anybody got any Sorcerer software? One of the Beebs is also used for programming EPROMs, assembling Z-80 code, and general hackery. I have quite a lot of software, I suppose (looking at all the disk boxes around here) but a surprising amount of it is systems software rather than applications -- most of the useful applications get run on Indys that aren't yet classic by the 10-year rule. If you want a list of O.S's: Paradox OS for a 68K machine (eg Sage II) CP/M for the Amstrad and Acorn Z-80 CP/M-86 for an Apricot which I no longer have CPN (CP/M-like OS) for the Torch UCSD p-System for the Apple ][ , Sage II, BBC Micro, and 11/23 RT-11 V2.00, V4.00, and 5.01 for almost any of my -11s RSX-11M 3.1 and 4.2 for the 11/23 and 11/73, and occasionally the 11/34 XXDP for any of the -11s DOS 3.3 and PRoDOS for the Apple ][ and //e RISC OS 2 for the Acorn Archimedes machines RISC OS 3 for the Acorn Archimedes and R260 machines Arthur (predecessor of RISC OS) for the Archimedes A310 RISC iX (BSD 4.3, ported) for the R260s BSD 2.11 for the 11/83 7th Edition for the 11/23 (and for the 11/73 if I rebuild the kernel) MOS 1.0 for the BBC Micros, plus a couple of modified versions, along with lots of additonal ROM software IRIX 5.3, 6.2, and 6.5 for various SGIs Solaris 2.3 and 2.7 for the Sparcs DOS 3.30 for the PC used to run 22-DISK etc DOS 6.2 for other PCs Windows 2.0, 3.0, 3.11, 95, and NT for PCs (English and German versions) Mac OS 6.something for the Mac Pluses Mac OS 7.something for the IIvx There's obviously a lot more but that's what comes to mind because I use it "every so often" rather than "once in a blue moon". For example, I have a licensed copy of RT-EMT which is an RT-11 emulator for Unix (mine was licensed to run under 7th Edition on the 11/23), but it's not something I use every day or even every year. 20 years ago it was in regular use. I also have some "classic" software, like Elite for the Beeb (I still have over a dozen shrink-wrapped copies), lots more Acorn/BBC software, HitchHiker's Guide to the Galaxy for DOS and CP/M-86, ADVENT for RSX and RT-11, Star Trek for umpteen machines, Galaxians for the Sorcerer, Kermit for almost everything I own that has a serial port (still extremely useful), assorted Claris software for the Mac Plus, Impression Publisher for the Arcs, Netscape (ie, version 1) and Mosaic for the SGIs, and probably 101 other things I can't think of this late at night :-) The point, I suppose, is that the hardware is more visible, while most of the software I use daily isn't exactly part of the "classic" collection. The software is at least as important, of course, as is the documentation; it's just less tangible. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

1702A EPROM Programming

by groberts＠mitre.org

I've been working with someone who has an old 8080-based single board computer he's trying to get to work. We're investigating several possible problems but it's starting to look like there's a problem with the EPROM. I have the ROM code he needs and will be checking out the EPROMS, but we may be faced with a need to reprogram one or both of these. They're the old 256 byte 1702A Intel chips (ceramic). I've only programmed the 27xx series but have read that the 1702's are "really difficult" to program. Was wondering if folks in this group could comment on how to proceed if/when we decide we need to reprogram one of these. Are there more modern plug compatible alternatives? We may also need to replace one or both - any sources known other than eBay? thanks. p.s. FYI, the computer here is the "MMD-1", an old 8080 trainer/breadboarding box. here's a picture i found on the web: http://online.sfsu.edu/~hl/c.E&L-MMD1.html - glenn
