I was going to do some VAX VMS tinkering today and my hobbyist licenses have expired. I thought this is where I got the licenses last time around but now the domain name appears to have expired: http://www.openvmshobbyist.com Anyone know anything about that? Is there somewhere else to get licenses now?

Micropolis1355 to 1325 (RD53) conversion

by useddec＠gmail.com

I have a few Micropolis 1355 drives I am looking into converting into 1325 drives. Has anyone know how, tried to, or ever done this? Is the HDA the same? Can the logic board be modified, or does it have to be replaced? Any info would be greatly appreciated. Thanks, Paul

I hope you understand that a line drawn from one point to another point does not form discrete points. It will be a straight line, not a series of discrete pixels along that straight line. You will not the the "traditional" moiree pattern if you were to draw lines in a spread from a certain point, as you would on a pixel based display. The 12 bit resolution sets a limit to where you can place the beam, but on a line between points, it can be at coordinates that cannot be expressed in 12 bit coordinates. Johnny

C64-C128 CP-M Cartridge Interest

They're dead easy to assemble. The only "problem" components are the unreasonably large EPROM and SRAM chips, and even they aren't too tough to find. -Dave -- Dave McGuire Port Charlotte, FL -----REPLY----- Hi! Due to numerous builder requests, we fixed the RAM/ROM size issue with SBC V2. SBC V2 accepts 28 and 32 pin ROMs (EPROM, PROM, EEPROM, or Flash) which is pretty much anything from a 27256 to a 29C040 or 27C080. You could probably go smaller if you want although I haven't tested it myself. Also the RAM accepts 512KB or 128KB SRAMs. All set with config jumpers. There are several other improvements which fixed several bugs from SBC V1. Maybe what is needed for the C64 CP/M cart is a expansion port to ECB interface board. Then plug in an N8VEM SBC, SBC-188, or whatever and use the ECB peripheral boards along with your C64. We have a 6809/6802/6502 to ECB bridge board that might be a basis. Make the C64 appear as an IO port on the ECB and as a memory mapped IO on the C64. Plug in SBC V2 for your CP/M-80 cartridge or SBC-188 V1 for the CP/M-86. Just an idea. Back in the day, I used to have a C64 with a CP/M cartridge. It was great -- Nevada FORTRAN rocks! Thanks and have a nice day! Andrew Lynch

PSU for MicroVAX 3400 Not Faulty But Not Working

by robert.jarratt＠ntlworld.com

A while back I mentioned that I have a MicroVAX 3400 with one of the H7868 PSUs not wanting to work (green light fails to come on). I have just tried the "faulty" PSU in a MicroVAX 3500 and it works just fine. I took a PSU >from the 3500 and put it in the 3400 and it does not work in the 3400 either, only in the 3500. So clearly there is something else that is causing the problem and I am looking for suggestions, especially as the machine is in an awkward location and hard to dismantle speculatively. As a reminder this machine was working fine and I had not done anything at all to it prior to its failure, I had not moved it, changed any components or anything. Regards Rob

Apple Lisa 2/10 - Progress

by terry＠webweavers.co.nz

More progress, I was kindly donated a IWM chip for the Lisa 2/10 by the original seller of these Lisas I have. He extacted it from a Mac 128 board he had lying around. I'm happy to report the machine now boots up. I'm not sure how much further I'm going to be able to take it though. The widget AND the floppy drive both have issues. I feel I might be able to fix the floppy. The widget seems a pretty complicated piece of machinery, info is sparse and I think might be beyond my limited skills. Here is a description of the problem with the widget. The certainly spins and I can hear a definte clack when the break comes off. I can hear drive seeking noises and the light flashes. I then get an "Error 82". From what I can read this is a fairly generic error which just means the internal drive is not working properly. I've tried to install the Lisa Office Suite and Macworks XL 3.0 from floppy. In the former case I'm told there is no suitable hard disk to install on, and the latter throws up an error 96. I've reseated all socketed chips to no avail. It could be a case of just requiring a low-level format, but I can't find anything on the web that suggests anyone actually knows how to do this. The 400k floppy drive has a weird problem. The stepper moves a little on a disk access call but the motor to rotate the disk doesn't go? The disk ejects ok. Things have been cleaned and lubed and I am using DD disks this time. I suspect it might be a sensor problem because once I was examining the drive when the machine was accessing it and tilted the embedded disk up slightly at the front. Suddenly it whirred into life and loaded the disk and the next disk I put in. Then it stopped working again after that. It could be a sensor maybe? Interestingly my other (spare) 400k shows exactly the same problem? However, the drive from my recently fixed Lisa 2 is fine and it was that drive I used to attempt to re-install software on the widget. I'm going to persist with trying to fix the floppy drives. Given that at least one of the drives did work for a short amount of time is hopeful. If nothing comes to light on the widget, I'll either just abandon trying to fix it and be happy with just a working Lisa 2, and/or perhaps simply look at getting one of these: http://cgi.ebay.com/Profile-Widget-Emulator-Board-Apple-Lisa-Apple-III-/140… .It's quite expensive though and I do like to have things original. I'll have to mull on it.

Using whiteboard cleaner on floppies

by aek＠bitsavers.org

I thought this was an interesting discovery if you're willing to sacrifice the media to recover some data. I've been trying to read some nasty old 360k 5" floppies circa early 80's, the kind that squeek and strip the oxide off in nice little rings. These were probably made from the same nasty stuff they made early 80's magtapes out of. Thinking this might be a dirt/lubrication issue, I tried applying whiteboard cleaner to the disk while still in its sleeve using a lint-free cloth across the slot on both sides, rotate, repeat around the whole disk, and after a few head cleanings was able to recover the data (and the squeeking stops). Weber Costello Markerboard Cleaner (from the label, after water) octylphenoxy polyethoxyethanol trisodium phosphate ethylene glycol monobutyl ether it's probably the glycol acting as a lubricant

Gould electrostatic printer/plotter

by wmaddox＠pacbell.net

The weekend before last, I picked up a Gould 5010 electrostatic printer/plotter along with some PDP8 gear. The technology is interesting. It writes an electrostatic charge directly on the paper, and develops with a liquid toner "fountain" as the paper exits the machine. Mechanically, it's quite simple, with just a single stepper motor to advance the paper and a pump to recirculate the toner. According to some patents I found on the web which appear to match the configuration of the write head, the pins are activated by a clever coincident-current addressing scheme that avoids the need to dedicate a driver to each pin. The product line was eventually bought by Calcomp, which continued to manufacture electrostatic plotters into the 90's. A successor company still provides paper and toner for some models, but the 5010 is not mentioned on the website, and I have no idea whether supplies made for the newer models will work in the 5010. The printer looks reasonably good on the outside. Internally, there are a few rusted places that could use cleaning and repainting, but it doesn't look like it's structurally or functionally compromised in that respect. The vinyl tubing for the toner circulation, on the other hand, has turned brittle and most of it is missing, and it looks like there has been some toner leakage/spillage at some time in the past. Most distressingly, the electrostatic write head is gunked up and/or corroded, and I suspect it is no good. The printer is a free-standing unit, but not particularly heavy. Two guys lifted it into the back of a minivan without difficulty. Before I strip this thing for parts (it has a couple of nice power supplies, among others), is there any interest in it? Does anyone else have such a printer and need parts? --Bill

Debugging a 386 motherboard...

by classiccmp＠philpem.me.uk

Here's one for the PC gurus (I know there are a few of you here!) I've got the 386 motherboard on the bench. It's got four 1MB 32pin SIMMs installed (it can take eight), no graphics card and my POST code display card (which arrived in the post this morning). I've set the jumpers per the manual: http://stason.org/TULARC/pc/motherboards/I/INFORMTECH-INTERNATIONAL-INC-486… The CPU on this thing is an AMD Am386DX-40. The math-coprocessor (Intel 80387DX-33) has been pulled for now. BIOS is an AMI (American Megatrends) BIOS, label on the chip says Copyright 1992. This is the BIOS which has the atrocious magenta-and-cyan setup screen. The POST card is reporting stable power, RESET inactive, and a valid I/O clock. After powering up, I get the following sequence of POST codes cur prev -- -- holds for a second (or so) 02 01 holds for ~15 seconds 06 05 holds for a second 0d 0c holds for a few minutes 00 0d holds forever The POST card has two displays: CUR and PREV, for Current and Previous code. CUR is the code most recently written to the debug port, PREV is the one before that. Now, according to http://www.postcodemaster.com/AMI91.shtml , 0D is "CMOS Shutdown Register Test to be Done Next", and 00 is "Going to Give Control to INT 19H Boot Loader". Does anyone have any clue what these error codes actually mean? Complete guess here, but it looks like the BIOS is having trouble talking to the CMOS RAM chip. Going by the Dallas datasheet, the most likely candidate is that it's writing 01X (i.e. 0,1,something) to the enable bits in CR1, then reading it back to make sure the control register was set up correctly. The readback failed (repeatedly), so it got stuck in a loop. Obviously without a disassembly of the BIOS, it's pretty hard to say for definite that this is the problem... but does what I'm saying sound at least reasonably plausible? I'm thinking my next step should be to plug a couple of Harwin pin headers into the turned-pin socket and probe it with the logic analyser... Does anyone have any other ideas? -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

3B1 Unix PC emulator -- keyboard driver (half) done

by classiccmp＠philpem.me.uk

Hi guys, I've just finished adding a rudimentary keyboard handler to my 3B1 emulator (http://www.philpem.me.uk/code/3b1emu). Problem is... it doesn't quite work. I can get into the test software, and if I hit a key it'll drop into the main menu. Problem is, when I get to the main menu, it doesn't seem to recognise the commands I'm entering. That is, I can enter a menu item number (e.g. 6 <CR> for Goto Subsystem Menu), it echoes to screen correctly, but then the screen clears and I'm thrown unceremoniously back to the main menu, instead of getting passed along to the subsystem menu... This happens with all the possible menu selections, and the "expert mode" command ("s4test"). Is anyone aware of any quirks with the test software which might cause this type of behaviour? Does anyone happen to have a 3B1 and an RS232 protocol analyser (or a logic analyser with RS232 decoding)? It'd be really handy to have some dumps of the data sent and received by the 6850 ACIA (the keyboard comms controller chip) when the keyboard is initialised, and when various keys are pressed... (If I had a 3B1 of my own, it'd be on the table downstairs with a keyboard sniffer cable and my HP logic analyser mainframe plugged in...)

cctalk Digest, Vol 90, Issue 19 [Subject: Seeking: IBM Coding Forms]

by vintagecoder＠aol.com

Hi Jeff, I have found several on bitsavers.org and maybe one other place. There may be some overlap with what you found but I would be willing to email them to you if you're interested. They're whoppers, about 1M a piece. I guess that is nothing today, but this is my first post and I don't want to start sending attachments to the list. It usually takes right about a week for me to become persona non-grata and I don't want to give anybody an excuse to change the timetable. I don't like change. So the best thing is for you to get them now before I get thrown out of here. I have about 6 different coding forms that I can find at the moment. I could swear I had an RPG coding form but I cannot find it and anyway I've been trying to cut down. I have 3 assembler forms including one in German or Swiss (both Greek to me) and one for System/3. The others are for COBOL and FORTRAN and a weird print layout form for a 150 character width page. I don't know who came up with that abomination since where I come from everybody knows anything past 132 columns isn't worth reading. I am constantly trying to find a way to deal with the huge quantity of archival stuff I have and haven't succeeded until now. There may be more hidden somewhere. I would like to say "Hello" to the list members and thank the list owner for providing the list and the website owner for providing the web site. My background is large IBM systems but I am interested in just about anything that lights up, hums, smokes, or goes bang when you get the wires twisted the wrong way. I am interested in programming languages, usually the older the better although IBM (mainframe) assembler will always be my favorite. At the moment I'm on a retro computing spree trying to learn how to code in DOS assembler. I am having a hard time finding books for that online.

New Corvus Mac Disk images...

by curt＠atarimuseum.com

Hi, Okay, well I was told that my original images zipped up on the PC side lost the resource forks and other nuances of the Mac Disks with which they were written to originally... So, I went back to the Powermac, it creaked and moaned a bit due to some battery issues and corrupted HD, after a reinstall of OS 8.1 (7.5.3 just didn't want to cooperate today, though I did finally did take all of the 19 damned disk images and make an Install CD image of it all finally) I got the Mac back up and running... I know, I know... Mac's after OS 7.6 can't read 400K diskettes... WRONG! They can, but with a little help from a wonderful utility I found on macgarden.org called Diskdup + 2.9.2 (the earlier 1.3.2 does NOT work)... Read all of the disks in perfectly, even allows you to save them in its diskdup format or in Apple diskcopy format... So I saved them in both, plus I made SEA images as well just for good measure. Its late, I'm tired, and I need to catch up with some CPLD design work I'm doing, so this wonderful side project was a great diversion for a couple of days, but back to work... I will revisit my Corvus website in a week or so, make the needed clean up and link changes, plus add in some great photo's of a killer Concept setup sent to my by a former Corvus engineer... so I'll be working on the Corvus site more in a week or so... in the meantime: http://www.corvusmuseum.com/software/mac/corvus_mac_disks.sitx Curt

Seeking: IBM Coding Forms

by silent700＠gmail.com

What started out as a novelty search for an old IBM COBOL coding sheet has turned into a serious-ish quest: I am now looking for any original IBM (and other) coding forms so that I might build a collection on our documents site. As for IBM, Google has helped me uncover the part/form # GX28-1464 for the COBOL form, GX09-0011 for FORTRAN and GX21-9279 for Assembler. More useful would be part # GX21-9818, which is listed as "Coding Forms Masters" and may contain these and other forms. If anyone has these and can a) scan them with high quality or b) lend/send them to me for scanning, I'd much appreciate it. Of course, if my Google-fu has failed and they're already out there, pointers to the downloads will do, too. -- jht

Anyone want an IBM/Hitachi 5.25in 2.4MB floppy drive?

by classiccmp＠philpem.me.uk

Hi guys, I'm toying with the idea of importing a couple of Hitachi HFD532EIU 5.25in 2.4MB floppy drives from the USA. Thing is, the postage on these is rather steep -- they won't quite fit into a USPS Small flat-rate box, and the next size up is the $47.50 Medium International flat-rate box (or $65 via Priority Mail in the seller's own box... yeah, right). So here's the question. Given that each drive costs $15, plus $47.50 shipping for all three, would anyone be interested in taking one or two of these drives off my hands for the cost of the drive, plus a contribution towards the original postage fee (the $48)? (I'm also open to offers along the lines of "I have a spare you can have for less money!" -- I only need one drive, and maybe a spare) Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

RFC: DiscFerret configuration files

by classiccmp＠philpem.me.uk

Hi guys, I'm working on the configuration file format for the DiscFerret. As I might have mentioned earlier, this is based on the Lua programming language -- in fact it *is* Lua. To load the config, the DiscFerret tools fire up a Lua virtual machine, compile the config file into bytecode, then run it and pick the config values out of the VM's global state. What this gives you is an absolute ton of flexibility: you can do things like use a FOR loop to generate repeated Drive or Format specs. Something like this: for kv in { "pc35a", "pc35b" } do drivetypes[kv] = {} drivetypes[kv]['friendlyname'] = kv drivetypes[kv]['crossed_cable'] = true end In the DiscFerret implementation, you have two config files: - DriveSpec: these tell the software how to talk to a given drive. Basically, what to do with the I/O lines. - DiscSpec: these tell the software what the parameters of a given disc are. Minimum/maximum track numbers, double stepping required (or not), hard/soft sectored, and so on. ( There are also DecodeSpec files, which MagDAS uses to decode transition data into disc images -- and which I'll document when I've actually designed them! ) Here's an example DriveSpec file: --------------------8<-----------8<---------------------------- --[[ ####################### # DiscFerret Disc Drive Specification File # # PC 3.5in Drives A and B, twisted cable or CBL-01A cable kit ####################### ]] -- DriveSpec version flags drivespec_version = 1.0 -- Drive types recognised by this drivespec drivespec = { pc35a = { -- Passed to Drivespec functions drivetype = "pc35a" -- Shown to user friendlyname = "PC 3.5\", twisted cable (CBL-01A), drive A" -- Default step rate in milliseconds steprate = 3.0 -- Spin-up time in milliseconds spinup = 1000 } pc35b = { drivetype = "pc35b" friendlyname = "PC 3.5\", twisted cable (CBL-01A), drive B" steprate = 3.0 spinup = 1000 } } --[[ Given the drive type, track, head and sector, return a list of output pins which need to be set. Called once per sector on hard-sectored media, once per track on soft-sectored media --]] function getDriveOutputs(drivetype, track, head, sector) pins = 0 -- 3.5in FDD settings are really easy to set up. First start with drive selects. if drivetype == "pc35a" then -- Shugart DS0 = motor enable A, DS2 = drive select A pins = pins or PIN_DS0 or PIN_DS2 else if drivetype == "pc35b" then -- Shugart DS1 = drive select B, MOTEN = motor enable B pins = pins or PIN_DS1 or PIN_MOTEN else error("Unrecognised drive type '" .. drivetype ..

Not bad. You could even go as far as generating all of these in code when the script loads. So on to the point of my message: does anyone have any comments to make on this type of config file format? Is there anything you'd like to see added, or done differently? Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

I agree that Citroens are wonderful, I had the opportunity of test driving a DS19 (or Pallas 21 or something probably) when I was 19 or thereabouts, on a French gravel road full of potholes. Absolutely fantastic suspension... French domestic wiring, on the other hand... :-O I remember getting a shock from a light switch, in my French godmother's house in a village in Charente-Maritime (same place I drove the Citroen). There was a fuseholder in the switch and the cover was broken and I happened to touch the bare metal. And I also had a look at the wiring in her Paris apartment. The previous tenant had "improved" it, using lots of "sparadrap" (sticking-plaster) to connect the extra wires... A wonder the place hadn't burst into flames. French domestic wiring is more like doll's house wiring. Flimsy 2-pin plugs where you connect the wires by jamming the bared ends under the pins, which screw into the plastic body of the plug. And so on. A Swedish inspector would probably have a heart attack merely from looking at it. Jonas

Acorn floppy interface question

by afra＠aurigae.demon.co.uk

Hi all, This is going to seem like a weird question...... Does anyone know why on almost all of the Acorn machines with disk interfaces (including at least one non-Acord designed one), they gate the drive select signals with the motor on signal. e.g. drive select is inactive unless the moror is also on ? This seems to be a peculiarity of Acorn as none of the other machines I am familliar with do this (Dragon, CoCo etc), even when they use the WDxa7xx type controlers. Though I guess cirtainly with the Atom / BBC A/B it may be a requirement of the 8271, it seems odd that it was carried over to the machines that only ever had 177x controlers. Cheers.

OT: american vs european 220

by brianlanning＠gmail.com

In the US, two separate 110 legs are delivered to the house. When we need 220, the magic of constructive interference is applied, and we get 220. The 220 is delivered to the appliance as two separate 110 wires, a neutral wire, and sometimes a separate ground wire for safety. Because of this arrangement, sometimes appliances (I believe, maybe I'm wrong) will pull 110 from one of the legs to power electronics in the appliance. But I think european 220 doesn't work this way. Is one 220 leg delivered to the house? And the electronics work off that 220 leg? Or are two 110 lines delivered and every outlet gets the sum of those two 110 lines? If it's not two separate legs, I'm thinking that it will be impossible to wire an american 220 appliance to work with european 220. Is this right? brian

No switched sockets at all here, unfortunately, possibly with the exception of sockets for electric irons in communal laundries in blocks of flats etc. And coffee makers in workplaces etc are always connected through a timer, since there have been fires caused by coffee makers boiling dry and the protection device having failed closed-circuit.

Many years ago I witnessed a very experienced electrician getting the hair dryer treatment from his boss because he had used a green/yellow piece of wire for a phase connection in an industrial installation. Here unfortunately there is no way of knowing which wire is live on the appliance, since the plug can be connected either way round. > I > beleive that some countries (Germnany?) oftn have a pair of 16A socket > outlets protected by a single 32A breaker.

Modern switchboards have miniature breakers for each circuit, the kind with both a magnetic and a thermal trip. Older installations only have a fuse. If you connect a shaver or something to the socket and the shaver shorts out, I suppose it is possible that the insulation on the shaver cable might melt before the fuse blew (shavers usually have a 0.5 mm2 cable). > > But more seriosuly, I feel I might well die from electrocution.

Happily for me, enlargers are cheap second-hand nowadays :-) (as is old audio gear, Revox A77s or B77s can be had for very reasonable prices for example. I have a very nice Marantz amplifier which I got cheap, and a Technics FM tuner which probably weighs nearly as much as the BC-312 shortwave receiver I used to have). Jonas

Over here (Sweden) all bulbs are ES and all holders have an insulating exterior. If you remove the bulb and poke your finger inside with the holder live, you may well get a shock, since mains sockets aren't polarised here. Most people don't usually do that however, not even the cognitively challenged. The bulbs don't wobble about in an ES holder, IIRC they do in a bayonet holder. The French use bayonet holders and that IMO says a lot about that type of holder. Jonas

The obvious snag was that it didn't have a mains lead and the mains input connector was an oblong thing a little flatter than an IEC chassis mounted connector. I removed the original connector, made the hole a little larger and fitted a new IEC connector. There's no shortage of IEC leads and I don't want to end up needing a selection of different power leads for different items. Sometimes it's easier to put up with something I'm not than keen on. Even if they don't feel that secure, I can't argue with the sheer numbers in use and the small number of reported problems with them. Regards, Peter Coghlan.

After a poor turnout at my place of work, I canceled trying to hold meetings there. Instead, I created a discussion group for the Historical Computer Society. There are a few of us there now, and we are building a grassroots organization that way. This is a group to become a lot like MARCH (http://www.marchclub.org/) for the greater Atlanta / southeast US region. A few of us had our first meeting in a restaurant yesterday, so I think that is a good start. More information is here - http://www.classiccomputing.com/CC/Meetings.html Anyone in this area, please consider becoming a part.

Tektronix 4010/4014 terminal printer project

by legalize＠xmission.com

OK, I've been studying the circuit diagrams and service manuals for the Tektronix 4014 printer interface: <http://bitsavers.org/pdf/tektronix/401x/070-2303-00_4014_4015_Service_Mar79…> <http://bitsavers.org/pdf/tektronix/463x/070-1831-02_4631_Service_Nov79.pdf> I'm starting a project to create a modern printer interface for the terminal. This involves creating the optional target signal amplifier board for the 4010/4014 and creating a microcontroller based board that will drive the terminal like a 4631 printer and scan out the image from the storage tube for digitizing as a digital image. The amplifier board is what distinguishes a 4010/4014 from a 4010/4014-1 and provides the signals for the printer. The original 4631 printer is a completely analog device that scans out the storage tube and transfers the electrical signal to a dry silver paper for printing. This design will treat the analog signal supplied to the printer as a signal for digitizing into a raster image. I plan on housing mine inside a 4632 video hardcopy shell with a modern printer inside driven by the controller. Who knows, this project might make those 4631/4632 printers useful again, considering that noone is going to be getting a new supply of dry silver paper anytime soon. I'm looking for other people that have hardware design experience to join me on this project. All resulting EDA files will be made available under a suitable open source style license. Please reply to me off-list if you are interested in collaborating with me on this project. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

I've an RL02 drive that I need to dispose of. It mostly works, but has occasional read errors--possibly dirty heads or adjustments are needed. It is missing the two cable connectors on the back (I needed those), and the rack rails (never had those). The drive is free to anyone for pick-up in Minneapolis. And while on the RL02 subject, I'm looking for two cabinet kits for RL02 controllers. e.g. CK-RLV12 type bulkhead connectors. Does anyone have these for sale or trade? Cheers, -scott
