How to enable USB drives in both Windows 98SE AND MS-DOS 7.1.

by terry＠webweavers.co.nz

The title might suggest to topic is not vintage, but the reason I did this myself was to facilitate classic computer disk imaging. I?ve recently given USB drive capability to the MS-DOS 7.1 environment in a Windows 98SE computer I use for the purpose above. It was a bit of work configuring the machine to ensure both the MS-DOS drivers and the Windows 98SE drivers co-existed peacefully. I'm no Windows 98 guru (or MS-DOS guru for that matter) so it may not be the most efficient or elegant of solutions. However, it worked for me. That being the case I thought I?d document what I did. Hopefully the article will be useful to others who might want to do this. http://www.classic-computers.org.nz/blog/2018-02-05-USB-in-MS-DOS-and-Win98… Terry (Tez)

anyone recognize this blank board?

by aek＠bitsavers.org

https://www.ebay.com/itm/311965565048 The same seller has a VT180 and some variant of the VT100 with an expansion board I don't recognize Interesting thing about the blank board is it says "VT-11X" on it and it looks like it would have been an 8-bit CPU looking at the string of DRAMs on it.

DECwriterIV/LA100s and large DEC monitors available, Cambs UK

by binarydinosaurs＠gmail.com

Hi folks, Clearing out some of the larger DEC pieces I have, does anyone want these before I offer them to the Centre For Computing History? They?d need to be collected from Cambridgeshire, or I can deliver them if the distance is reasonable. I kind of need the space quickly too. Usual caveat as working-when-last-powered-up :) 3x LA100-CA with keyboards VRT19 with video cable, last powered up in Dec 2014 VR319 mono VXT monitor VR261 mono workstation monitor VXT1200 VXT1000 Alpha 3000-400, maybe 2 if I can find the 2nd one.

Intel 8085 - interview?

by spacewar＠gmail.com

At some point I read an article or a transcript of an interview with an Intel employee (or former employee) who had been involved with the design of the 8085, describing how he had specified additional instructions over those of the 8080, and they had been implemented in the silicon, but then the decision was made to not document any of the new instructions other than RIM and SIM. I no longer recall which Intel employee that was, and can't find the article or interview. Does anyone else remember that, and perhaps have a copy? Eric

Hi, can I appeal to you (and everyone else who writes up these kinds of notes) to put this stuff on the Computer History wiki? When things like this get placed in the CCTalk archives (for which there is no search system other than Google), or on people's personal sites (ditto) - and I have in the past BTDT for both of these, myself - it's probably going to be hard to find them amidst all the other dross that a Google search typically produces, a couple of years down the road. With the CHWiki, we stand a chance of filtering out the useful information and making available, and _organizing_ all this stuff so that it's possible to find relevant information when it's needed... And no, I don't have time to upload all this stuff myself - I have too much other stuff I'm trying to work on! :-) So, please - let's get organized! Noel

Microvax II 'primer'?

by jules.richardson99＠gmail.com

So, I picked up (and I did just carry it into the house, and now I hurt) a Microvax II from another list member yesterday. Cosmetically it's a disaster (BA123 has a cracked top panel, broken wheels, missing front door, missing right-rear panel) but internally it appears to be complete; board wise we have: M7606 - CPU M7608 - 4MB ram M9047 - grant continuity M7504 - DEQNA ethernet M3104 - DHV11 8-port serial M7555 - RQDX3 disk controller M7546 - TX50 controller ... it's got a TK50 and hard drive (no idea of capacity). Operational status is a complete unknown, and I have absolutely zero knowledge about these systems - so my question at this stage is what background reading I need to be doing in terms of pre-powerup* checks, actually hooking a console, if there's a suggested minimal config I can use to diag the CPU, and then (assuming it gets to that point) how to actually use the thing (I'm assuming it was running VMS rather than Ultrix, but I don't know for sure). I'm wondering there aren't any handy tutorials out there, alongside whatever DEC docs are recommended. * e.g. for most machines I'd be thinking in terms of pulling all boards/drives, hooking up a dummy load to whatever PSU rails required it, and then at least running the PSU up in isolation first, but I don't know to what extent this machine requires some logic in place for the PSU to even run. cheers Jules

Google, Wikipedia directly on ASCII terminal?

by martin＠meiner.ch

Hello guys. I am a passionate collector of old computerhardware (PDP8?s) and terminals from the very early 70ies. It has always been my aim to be able toconnect a modem or an acoustic coupler directly to one of my ASCII terminals,dial a number and be connected?with Google! Something like Google-interface but convertedto match ASCII terminals (only text, very simple graphics). I am aware that all searches that returnpicture sand graphics will not be displayed. But at least search-page should bein plain text, and many websites may as well. Wikipedia would be great? Does anybody know if there exists such anaccess-number where this conversion is already made, or is there a small deviceon the market that allows on one side connect to a dial-up modem and on theother side to the terminal and doing the ASCII conversion stand-alone? ?It would be really cool to be able todemonstrate to folks that these terminals can actually look up pages on Googleand (with limitations) also access some pages. Something similar has actually been done in an artisticway a few years ago under: http://www.masswerk.at/googleBBS/or http://www.masswerk.at/google60/ But I need the real thing working where I canconnect my terminals to?? Any help is appreciated

PDP8E 3.75V on Omnibus issue

by mail.nickallen＠gmail.com

Hey everyone, thanks for always serving as a great sounding board and source of advice! I have an issue with a PDP8E which has an issue with the power supply.? The -15V, 15V, and 5V are good, and my Bus Loads board is good, but for some reason the power supply is bringing down the 3.75V signal from the bus loads to 0V (this is the DC VOLTS OK grey wire from the power supply). I'm having troubles finding the schematics of the PDP8e power supply, also any suggestions on what could be pulling the 3.75V to 0V (tested multiple Omnibus backplanes, and bus load boards, so I'm fairly certain it's the PSU). All help is MUCH appreciated, thanks!

I used Nero (or Daemon I think) to write CDs for my VAX but there will be plenty of other programs equally suitable. You don't need to do anything special, just treat them as an ISO image and let the burning software get on with it. Once written, Windows won't be able to read them so don't panic. If the burning software includes verification then it (not Windows) will be able to read them back OK. (I'm using VMS v7.3 but I'm sure this is no different). Generally AFAIK the CD readers on Vaxes (Vaxen - ugh!!) and Alphas will deliver 512 byte blocks but this isn't relevant for the image itself. Bob

EPROM baking

by Mark＠Misty.com

Hi, I am working on several projects requiring 2708 and 2716 EPROMs, and am finding some of my chips will not erase, and some will not take a program. I've also learned more in the past week than I wanted to know about repairing Data-I/O 29a/b programmers. I vaguely remember in the 1990s baking such EPROMs in the oven, but I do not remember temperature or time. I was surprised that Google didn't turn up anything useful with this info. I'm sure someone here will have some notes on EPROM baking. Mark -- Mark G. Thomas (Mark at Misty.com), KC3DRE

A couple of RL02 questions

by cramcram＠gmail.com

I've got two RL02 units. One is a parts unit and has an access plate for the door solenoid. I can open it. The other has no access plate nor is there a cutout for one. How do I open this cover with the power off? This is a newer unit as it has head lock screws on the bottom of the drive. The second question has to do with rack mounting. I want to mount this in a H960 cabinet but will obviously need to slide it out to replace packs. All the unit has is a thin rail on both sides that is riveted to the unit. It looks like chassis slides were there originally. Does anyone have either the DEC part # for the slides or a contemporary part # for one that will work? Thanks, Marc

I have used blue disks in a green shelf and green disks in a blue shelf. The modules come apart fairly easily and you can replace the drives or remove drives and use them as ordinary SCSI drives elsewhere - I have done that too. DEC and Compaq also sold DLTs in a StorageWorks module those can also be taken apart and the drive replaced but they are harder to get apart and you must pay attention if you hope to get it reassembled properly. > > Doug > > -- Richard Loken VE6BSV : "...underneath those tuques we wear, Athabasca, Alberta Canada : our heads are naked!" ** rlloken at telus.net ** : - Arthur Black

So the question is, does anyone happen to have a copy of that MDM CD-ROM? Or any versions of MDM on CD-ROM? MicroVAX Diagnostic Monitor Release Notes Order Number: AA-PK29E-TE These release notes describe restrictions, undocumented features, and other essential information about the MicroVAX Diagnostic Monitor (MDM) Version 5.0, Release 139.

wonky eproms

by dave＠661.org

I have a few tubes of ST-branded M27C256B UV-erasable EPROM chips. All of these fail to program starting at 0x200 until 0x27F. At 0x200, 0x00 is written, then until 0x27F, the bytes are 0xFF. What would cause this? Can it be fixed by an extra-long time in the eraser? Should I just break out the hammer? At least I know the programmer is capable of programming a TI-branded 27c256 and 29c256 flash chips. Might there be a bug in the programming software? FWIW, I'm using a Minipro TL855. Linux software is available at Github: https://github.com/vdudouyt/minipro -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.

IBM 5100 to 5110 Transitional Model

by santo.nucifora＠gmail.com

HI Wayne, I believe the KVA is increased because of the extra memory card. I have a 5100 with 0.4 and another with 0.336. The 0.4 has an extra memory card and is BASIC and APL as opposed to just BASIC. The printed 5100 badging on the front is not consistent but sometimes if it doesn't have it printed on the front, it's on a silver metallic emblem embedded in the top cover. If the 5100 badging is printed on the front, it may or may not have the silver metallic badge on the top cover. I have a top emblem model and a top emblem-less model yet both have the 5100 badging printed on the front. If you look at other photos on the net, you will see others with no front printed badging. This particular one had no front badging but has the emblem in the top cover and I think this is normal. I'm not sure which one is earlier/later but I would imagine that is why there is a difference. I can't explain the 5110/5100 difference on the bottom. Hope this helps.

IBM 5100 to 5110 Transitional Model

by wayne.smith＠charter.net

Has anyone noted this listing of what the seller is calling an "IBM 5100" on Ebay? https://www.ebay.com/itm/IBM-5100-B1-Basic-Language-16k-Memory-Powers- on-monitor-works-but-no-text/112776476816 While it is listed as a 5100, it lacks the 5100 badging on the front center panel (to the right of the power switch). In addition, the indicia on the bottom (https://i.ebayimg.com/images/g/9VYAAOSwaC9aapB-/s-l1600.jpg) indicates both models 5100 and 5110, and the KVA is listed at 0.4 whereas 5100s are 0.336. Compare the typical indicia on the bottom: https://tinyurl.com/ybmvms7u. The serial number is in the 5100 format of 10-1XXXX, but this unit has the highest serial number I have seen on a 5100 (10-15687). I am guessing that this is some sort of transitional version or perhaps a 5110 "prototype". Any thoughts? -W

RX02 Emulator Problem

by bill.gunshannon＠hotmail.com

I finally got a system running again and hooked up my first AK6DN RX02 Emulator.? Worked, up to a point.? I can boot >from it and read and write to it.? However, every once once and a while after doing a bunch of accesses the Green LED stays on and the system freezes.? Sometimes I can get back out of it with Control-C but sometimes it is locked? up so tight I have to reboot to get out of it. Anybody else see this behavior? bill

Data IO 29B / Unipak 2B adapter?

by mattislind＠gmail.com

I need to read a couple of Signetics 82S215 bipolar PROMs with my old Data IO 29B / Unipak 2B. But it needs a 351B-068 adapter. Does anyone has information regarding this adapter? I did find an old post in DATA_IO_EPROM at groups.io mailinglist that a man named Alfred Marin had boards. I even found his email but it bounced. Any other pointers in this subject? /Mattis

MACSYMA classic

by jnc＠mercury.lcs.mit.edu

> From: Lars Brinkhoff > notes on his progress are here: > https://github.com/PDP-10/its/issues/284 Ah, that sounds pretty good. The ability to re-create source, given the FASL, will really help. > In 1982 MIT licensed Macsyma to Symbolics, but also made it available > to the US Department of Energy. I wasn't involved with this, but my recollection from dribs and drabs I overheard was that DoE got a copy because they'd been the funding agency for a lot of the work - i.e. MIT didn't just give a copy to DoE, it was a requirement.

Modems & Xerox

by c.murray.mccullough＠gmail.com

I started accessing BBSs back in the early 70s with a 300 baud modem. >From there it went to 1200; 2400; 9600; 28.8K and 56Kilobaud. All on dialup! Now at 5 Mbits/sec. here in Ontario. An American friend has 250Mb/s download. Yikes! The classic computer era taught us patience didn?t it? BTW, one had to have a private phone line not a party line for a modem to work. Making our hobby more expensive! On the business-side of computing: Xerox sold 50.1% of its business to Fujifilm, Japan. Xerox Parc was a seminal institution in early classic computing era: Mouse and graphics input for instance. Happy computing! Murray :)

X11 expertise on ancient HW sought... (4-plane visual (overlay) via X-server on MS-WIndows)

by dimitris.theo.gr＠gmail.com

Sorry for undiggind this subject so many years later, but have you found a solution to your problem? I am facing exactly the same issue, and i have tried all possible windows X server options without success. The only possibility I am working with is with a Mac OS X server, which reports a 5-bit visual.

SuperTerm Maintenance Manual

by mike_t_norris＠hotmail.com

Hi Guys, I am new to the group, so let me know if this post is inappropriate. I have a SuperTerm Maintenance Manual that I am about to put in the bin. I am prepared to scan it if any one is interested, I could not find it on bitsavers.org, but I guess there may be one in the backlog? The SuperTerm was manufactured by Intertec Data Systems c. 1978, it was a 180 CPS dot matrix printer (RS232), quite often used as a console printer in place of a LA36, Intertec also did a speed up board for the LA36 (I may have details on that when I get through clearing out my loft), to make it a 150 CPS printer, although it was prone to carriage slams initially, same was true of the SuperTerm for a while, which also resulted in the carriage driver transistors burning out. The company I worked for produced a separate driver board to get around the problem, typical patch at the time. Regards Mike Norris

Foonlies

by lars＠nocrew.org

This document seems to imply that the Super Foonly and the Foonly F1 were separate machines. When I've seen them discussed, they always seemed to be uses synonymously. http://www.bitsavers.org/pdf/dec/pdp10/KC10_Jupiter/memos/foonly_19840410.p… SUPERFOONLY DESIGNED 1968-71 10,000 TTL IC'S 3 MIPS F1 (1978) 5,000 ECL IC'S 3.5 MIPS Also, except for the CCRMA F4 at Computer History Museum, does anyone know about any Foonly machine having been preserved?

DL10 documentation

by jnc＠mercury.lcs.mit.edu

> From: Phil Budne > FWIW, Found these bits > ... > Those bits and others can be found Excellent archaeology! With these, and the ITS sources (for which we have both the -10 and -11 sides), the register definitions in the early PDP-10 CPU manual, and the prints, it should be possible to write a programming manual for the DL10, to replace the one that's now lost. (If it ever existed - does anyone know?) Any chance I could convince you to enter all this stuff on the CHWiki DL10 article: http://gunkies.org/wiki/DL10 Lars (mostly) and I have added a little bit, but there's still a long way to go! Noel
