The three people who have yet to get the P112 kits they paid for have been emailed to verify that they're still at the snail addresses I think they're at. I will have a very small number of kits left over after this. I'm not saying how many until I've purchased some more parts and am ready to take orders. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Finding one IBM 2741

by spedraja＠ono.com

I'm doing a review of all the IBM stuff which I took from the Datacenter in the last cleaning. Having one 3279 in working state and one 3278 almost (the logic board needs replacement), plus one 3178 still alive and one 3174 ready to work with Hercules, I should like to get one 2741. As difficult as the lottery, I suppose, but for try it... Regards SPc.

SC Spreadsheet

by david＠thecoolbears.org

Does anyone know where source code is for the SC curses based spreadsheet - specifically, a version that will compile on OpenVMS on VAX? I have sc-7.16, but I'm not having much luck getting it to compile (it compiles OK on Linux). I saw some indications that pre-7.x versions will still compile on VMS, but 7.x and later will not. Executables would be OK, but obviously not as good as source.

NTSC video output from Sinclair ZX81?

by charlesmorris800＠centurytel.net

I'm dusting off my ZX81 with 16k memory pack (the pair cost me $200 in 1981!) and have already discovered that the Z80A chip has definitely gone bad. (The HALT\ output pin sits at an indeterminate-level 1.2 volts even with the logic IC removed, and the CPU is halted). I had a Z80L (good for only 1 MHz and the clock is 3.5 MHz) in the junk box, but even so, swapping it resulted in lots of activity on the address, data, read and write lines, etc. as well as video pulses coming out of the custom logic chip, pin 16. http://www.mainbyte.com/ts1000/good_schematic_hi.jpg I'd like to take the output from that pin, which currently goes to a "canned" RF modulator through a couple of resistors and a diode, and instead convert it to NTSC video, as I also have a 9" monochrome CCTV monitor (75 ohm input) which would make a compact display. Can someone help me with a simple circuit to generate the appropriate RS-170 1 volt p-p video signal? thanks Charles

TMA-11 Read

by iamvirtual＠gmail.com

Hi, I am trying to archive my tapes. I am having difficulty reading the tapes. I tried 2 tapes that are of low importance. I am able to read the first 2 records (the first record is 14 bytes and the second record is 512 bytes). I see the tape move for the read as well as the backspace operations. I setup a simulated environment to test prior to using real hardware. Using a slightly modified version of SIMH along with PDP11GUI and a virtual tape, I successfully read virtual tapes. Now that everything is working on a simulator, I am using the same code on real hardware. The real hardware is a PDP-11/10 with 32kw core memory, TMA-11 controller with TS03 tape drive. I also have a RK-11 controller with an attached RK05j drive which is available, but is not used during this scenario. I don't know the actual format of the tape. My goal is to get a binary copy of the tape suitable for use with SIMH. Now that I am using real hardware, I am getting a Record Length Error. I set the read buffer to 2048 bytes (1024 words). The values I have from the TMA-11 registers is as follows: MTS 001105 MTC 160202 MTBRC 000000 MTCMA 000000 MTD 000000 MTRD 000000 I am looking for some source code to figure out what is going wrong. I have reviewed the simple example in the TMA-11 documentation, but proper error handling is not performed. Thanks! ; +=============================================================== ; | read ; +=============================================================== ; | ; | Read record from tape.

RTE IV-B HP 7920 Grandfather and Primary system disc (NOS)

by hp-fix＠xs4all.nl

I've two HP 7920 RTE IV-B cartridges one Grandfather and a primary system disc for the HP 21MX both seemed to be unused and have been in storage forever..(and should be cleaned for use !) I don't have a HP 7920 drive I do have a HP 7906 in unknown condition and a HP 2113B which I love to see running RTE. So I'm looking for someone willing to : sell or trade me a HP 7920 drive, or someone transfer the data from the packs to tape or disc or any other solution which provides me with the RTE-IV software for the HP 2113. If can't get a HP 7920 then the packs are for trade. I'm living in the Netherlands so picking up a 7920 in Europe is possible, shipping the packs to the US also but only . Please react off-list -Rik

NorthStar stuff for sale

by lynchaj＠yahoo.com

Hi, I have one complete Northstar Dimension and another only missing some parts of the power supply. Northstar Dimension computers are quite rare machines from the era of transition from S-100 to the IBM PC clones. There are also a couple of Northstar Advantages in the original boxes. The Dimensions are also in the original boxes. There are some spare parts for the Dimensions and Advantages including some software and maybe some documentation. One more item is a NorthStar 15MB external hard drive. This is quite a large and rare unit. At least this is the only one I've ever seen or heard of. I am not 100% sure but it looks like it may be a 14" hard drive platter. Seriously, this thing is as big as a full sized S-100 chassis by itself. Due to the nature of these items, they are for local pick up only. I am not interesting in shipping these items. There is also some NorthStar software in original boxes, packing, etc TSS/A HD Horizon Order Entry and Invoicing HD Advantage (2) Inventory Control and Analysis HD Advantage Graphics BASIC DOS PIO Advantage Info Manager II HD Advantage TBS/OS Advantage Enhanced WordStar Advantage CP/M (5) Enhanced WordStar Horizon dBase II Advantage CP/M (3) dBase II Horizon 8/16 Upgrade Advantage Accounts Receivable HD Horizon NorthPlan FD Advantage NorthWord II FD Advantage TurboDOS 1.1.1 Horizon NorthNet Advantage (with board) CP/M 2.2 Rev L1.0 Horizon General Ledger HD version Advantage Accounts Payable HD version Advantage Image Maker Advantage CP/M TurboDOS I am willing to sell but due to size these need to be picked up (Ohio) in person. Please contact me for more details. Thanks! Andrew Lynch

Lots of Amiga stuff available

by dbetz＠xlisper.com

I recently acquired a bunch of Amiga equipment that I'm not sure I'm ever going to get a chance to use. I'm currently looking for someone who might want this equipment. I got it for free so I will pass it on at no charge as well. Just briefly, the main items are: 1) Two Amiga 500 computers 2) A sidecar style hard drive for one Amiga 500 3) an Amiga CD32 game machine 4) a Paravision SX-1 attachment for the CD32 with lots of additional ports to allow the CD32 to be used as a computer 5) two 1084s monitors 6) numerous floppy drives including a number of 3.5" drive and one 5.25" drive 7) software and manuals for most if not all of the hardware I've seen one Amiga 500 boot from the hard drive into Workbench. I've also seen the CD32+Paravision unit boot into Workbench from a floppy. I don't know the state of the second Amiga 500 but it appears to be in good condition. I'm in southern NH and would like someone to take all of this equipment. Thanks, David Betz

Microcolour terminal

by ard＠p850ug1.demon.co.uk

Has anyone ever come across a 'Microcolour' terminal? It was made in the UK by Microvitec, who were better known for monitors (often BBC micros were used iwth Microvitec Cub monitors). I have a couple of the Microcolour base units here, no monitors or keyboards. Here's what I've discovered so far... On the rear are connectors for 'Host' (DB25 plug), 'Printer 1' (DB25 socket), 'Printer 2' (DB25 socket), Monitor (DB25 plug), Keyboard (DE9 socket), mains in/out (mormal IEC connectors, a couple of fuses and the on/off switch. The only feature on the front is a green power-on LED. Insdie is a PSU (the 2 units I have differ in the PSU design, but that's not vert important at the momnet0 nd a crdcage containg 3 PCBs (with aslot for a 4th). These plug into a backplane at the front fo the machine using 64 pin A+B DIN41612 connectors. The loweremost PCB carries the Host, Printer 1 and Keyboard connectors. On this board are the processor (6809), EPROMs, RAM (some of which is battery-backed -- I have removed the leaking NiCdsm there is no other damage), 4 6551 serial chips (for the printer 1 port, which is RS232 DTE, even though it's on a socket :-(), the keyboard port (TTL level), and the host port (it uses 2 6551s for this so yuo can have split baud rates I guess), a 6821 (used at least for the Printer 2 port which is thus a parallel interface, a cable rund from a SIL header on the PCB to the DB25 socket o nthe chassis), etc. One of the EPROMs has a label 'Regis' which seems to suggest what protocol it may use. The other 2 boards are video-relates. One seems to be text video (6845, several 6116 RAMs in a row on one edge, another couple of 6116s which may well be programmable character generator, there's no EPROM on this board), and lots of TTL. There's a 10 pin header which is linked ot part of the monitor connector. The last PCB seems to be graphics related. It contains 128K of DRAM, some 74S189 SRAMs for a oolour palette and again lots of TTL. There's a 15 pin header that links to the montior conecetor. Now for the monitor connector. It's a DB25 plug. One pin is not fitted, one is wired to chassis ground. 9 of the remainder go to the text PCB (one pin on the header is not used), the remaining 14 go to the graphics board (again one pin on the header is not used). Now fo the odd thing. All those signals are TTL level. The output of the graphics board (12 pins on the header) are the outputs of those palette RAMs. In other words 12 bits digital (I asusme 4 bits each for R,G,B). The otuput fo the text board is similarly a 4 bit value (I think). And of course there are 2 sync signals, which I could identify. Vsync is 50Hz (not too suprising), HSync is 21.8kHz. In other words, EGA rates .Sothis thing used a specail EGA-like monitor with many more input bits. I suspect I am goign to start by hooking up a normal EGA monitor (assuming I can find one, I think I have a 5154 around here) to see if I can get some output, albiet with fewer colours than I should have and then try modifying such a montiro t oincrease the numebr of bits on the DACs. As for the keyhoard, at least it's synchronous serial (of the pins on the DE9, there's TTL level TxD and RxD, ground, +5V, +12V, -12V). I have no idea of the baud rate, etc, but if necesary I cna use a logic analyser to see how it initialises the appropriate 6551. -tony

Floodgap back up

by spectre＠floodgap.com

As shocked to see that I haven't been bounced off the list by now, Floodgap and all of its hosted projects are back in full operation on a new T1 from AT&T/DSL Extreme. Do not ever do business with Time Warner Cable Business Class. They took six weeks to do nothing, culminating in fairly nasty threats to their legal office to get them to release me from the contract. AT&T took almost four weeks, but at least they got the NIU in, and the router got activated today. Reverse DNS is pending. Sorry about the downtime. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- ** COMMODORE 64 BASIC V2 ** 64K RAM SYSTEM 38911 BASIC BYTES FREE ----------

RK05

by cc＠informatik.uni-stuttgart.de

Hi, I'm trying to repair my RK05 drive. It seems that it doesn't find track 0 when loading the heads, thus moving the heads to the inner limit, forcing a return-to-zero and starting all over again. I think the fault is on the M7681 card (cylinder address and difference), the output of E16 pin 8 (CAD3 zero detect H) doesn't change, nor does the input on pin 10. And here comes the problem: the M7681 isn't described in any DEC documentation I've found so far (apart from the schematics), only the older M7702 card (the function is practically the same, but they are completely different designs). The new card contains several undocumented TTL ROMs (8223). The output of pin 6 of E1 goes to the input pin 10 of E16, probably a difference==zero bit. So here comes my question: does anyone have a ROM listing of these ROMs, especially of E1? I'd like to know what exactly that ROM is doing. Christian

intel mds 225

by jzg22＠drexel.edu

... I've never seen one of those mds computers before, but as soon as I saw it I realized that it is what the Speech Plus/Telesensory Prose 2000 Speech Synth card which I have was originally meant for/designed for. The card I have is in a special speech plus 'prose 2020' metal case with its own power supply, and the two 'multibus'? edge connectors of the card are unused, power and serial and audio come from/go to special secondary connectors on the board. But clearly, without the special prose 2020 case, the prose 2000 card would be used in one of those computers with 'multibus'. Any chance you can dump the roms from the computer? Given that there don't appear to be any multibus cards installed, are there even any roms to dump?

DEC GIGI - Power Supply Replacement Success

by mark＠wickensonline.co.uk

Folks, Always nice when you've got a piece of good news ;) I replaced all the mains filtering capacitors in the original DEC GIGI power supply when one blew only to find that the power supply lasted another 10 minutes before losing power completely. At this point I decided given the relatively standard power outputs (5V 3A, 12V 1A, -12V 0.3A) I would source a replacement power supply. This arrived and was installed yesterday. It I guess unsurprisingly is substantially smaller and lighter than the original. The original cooling fan was removed as it was basically transformed directly from either the mains directly or one of the windings of the main transformer. I used the fan out of an external SCSI enclosure as a replacement, although I look to source a high quality brand new one. To me it looks like the fan primarily is for cooling the PSU only - given the fan location and the location of the plate that the PSU is mounted on it looks unlikely that the main circuit board would benefit much. The machine now happily powers on and I had an hours playtime last night with the local BASIC monitor. The GIGI now only exhibits one minor trait, and I'm yet to determine whether this is down to the LCD panel it is driving being at limits or whether there is a slight issue with the video generation circuit. Once in a while, every couple of minutes or so the LCD looses sync and the picture is dropped. This only happens for a fraction of a second, then the picture is restored as was. If anyone has any ideas I'm all ears. For reference I'm using a Iiyama AS4637UT, an old but extremely capable 18.1" 1280x1024 native panel. If anyone is interested I can post the horizontal and vertical frequencies it is being driven at. I plan on scanning the GIGI brochures I have for inclusion on bitsavers shortly. Regards, Mark

EDA Electronics cards??? got a bag of them duno what they're from

by tshoppa＠wmata.com

The form factor matches up to the Vector 22/44 0.156" card edge physical form factor standard. Which doesn't narrow it down at all. Millions of custom industrial systems (some micro-based, but most not) were built using these plugboard style systems from the 60's through the 80's. Vector sold card cages and proto cards; the one-offs usually used the proto cards but something that was made in small to medium quantity might have used a Vector card cage (perhaps hand-wired) and etched PCB's. Sometimes the backplane was a simple bus in the computer sense but usually not. Looking at the chip logos and mix of analog/digital I'd suggest this is from the late 70's/early 80's and is some kind of DAQ front end or perhaps digital-math servo system. You can narrow the date range down from looking at the date codes on the chips.

Well, I suppose it depends on your usage. To me, an 80G drive is huge; I can't generate relevant content fast enough. To someone who stores movies on their hard drive, it's unbelievably small.

Installing OpenVMS Software

by cool1＠thecoolbears.org

I have a VAX that I like to play around with. I don't know VMS very well, and it's fun to learn new (well ok, maybe VMS is old now) things. There's an application that I would like to compile, but it depends on bison. I'm trying to compile bison, but that process seems to depend on MMS. I'm assuming that MMS works like "make makefile" and you do "mms whatever.mms" to make the app. MMS doesn't seem to be installed, so I registered and loaded the license. The SHOW LICENSE command says that the license is there. Now I need to install the application. I have the Montagar CD mounted and I can browse it's tree structure, but I can't find the kit that includes MMS. I thought maybe the C language kit and I tried: @SYS$UPDATE:VMSINSTAL CC064 DUA2:[CC064.KIT] ...which reinstalled C, but no joy on MMS. Any suggestions?

seeking ExperLisp by Expertelligence for Macintosh

I used this in the 1980s and would like to get a replacement copy for the one I lost - thanks. Last year on eBay someone purchased a large collection of Macintosh diskettes, one of which was an ExperLisp diskette, so if that person is a cctalk-er I would appreciate a reply. It was released for the Mac 512K and later Macintosh.

TTI 8510 Manual and/or switch settings...

by lbickley＠bickleywest.com

I recently acquired a clean TTI (Transitional Technology) 8510 8mm SCSI tape drive. I've searched Google extensively - but have found no manual or even a switch settings guide. It emulates an Exabyte EXB-8200/EXB-8500, a DEC TK50Z, an IBM 2.3 GB or the native TTI 8510 (from Google). It has twelve dip switches, three of which I've found to be the SCSI address - the others are a mystery. Does anyone have a manual or guide to the switch settings for this tape drive?

Interesting email addresses of old...

by mark＠wickensonline.co.uk

I was just trawling through some of my file archives and found my old email address when at University: mwickens at vax2.luton.ac.uk - from 1993 to 1996 At the time I wasn't really into VAXen, but subsequently have wondered about the VAX that handled my emails during that time. In the last year a new Alpha system came online, and new email accounts were set up on that box. Anyone had interested email addresses in the past, or an email address which represented a nostalgic time in their life. The fluidity of email addresses interests me academically and professionally - I work on systems which traditionally have involved postal communication, but are moving over to email based communication. This represents a challenge due to the fluidity of email addresses over the course of the years. Regards, Mark.

New rsync mirroring at trailing-edge.com

by shoppa＠trailing-edge.com

Last weekend I promised to enable rsync access to the archives (and mirrors) here. I've set up the following rsync (no password required) archive sets here: ftp : Public rsync access to ftp://ftp.trailing-edge.com/ area pdp-10-tape-images : public rsync access to the PDP-10 tape images, i.e. http://pdp-10.trailing-edge.com/ bitsavers-mirror : public rsync access to my local bitsavers mirror, i.e. http://bitsavers.trailing-edge.com/ Suggested rsync commands would be, for example: mkdir ./pdp-10-tape-images rsync -rlptu -v www.trailing-edge.com::pdp-10-tape-images ./pdp-10-tape-images mkdir ./ftp.trailing-edge.com rsync -rlptu -v www.trailing-edge.com::ftp ./ftp.trailing-edge.com mkdir ./bitsavers-mirror rsync -rlptu -v www.trailing-edge.com::bitsavers-mirror ./bitsavers-mirror Realistically the pdp-10-tape-images and ftp sites don't change often, butm my bitsavers mirror is kept up to date. I like to think my outgoing bandwidth (20 Mbit) is pretty much infinite, this looks like a good way to find out :-) ftp racks up to 3.5 Gbytes. PDP-10 tapes racks up to 2.2 Gbytes. And bitsavers-mirror racks up to 126 Gbytes. Tim.

Somebody I know had a Volvo V70 that just refused to start one morning. Nothing obviously wrong, it just would not start. It had to be towed to a Volvo dealer. IIRC the problem turned out to be that two of the car's computers decided they didn't want to talk to each other. A software upgrade fixed the problem. It may even have been the case that none of the computers had to do with engine management. The owner of the car is very clueful about hardware, software and cars, but it would still have been a major undertaking for him to even find the problem, let alone obtain the software upgrades. > And I realyl don't understnad why service information is not supplied > with (or at least available for) devices that are almost cetainly > goign > to be owned and used by people with eelectroncis knowledge -- > soldering > stations , mutlimeters, 'scopes, etc. I've still not bougth a new DMM > after my Fluke failed last year because I've yet to find a > manuafactuer > who will supply a service manual. > Because they want you to either buy a new unit, or send the unit to one of their own facilities to be repaired? In case of car manufacturers I believe a significant portion of their profits comes from spare parts and service. Do you have a mobile phone? Modern ones seem to be designed to break down slowly after about 18 months, they are full of custom parts, and the people who repair them do their best to drive you mad. My work phone is (hopefully) being repaired right now. It is 17 months old, the display went permanently blank around August 6th, and the repair people have most likely not started working on it yet. I shall probably have to wait another 2 weeks for it. /Jonas

More DEC Bad luck.

by bdwheele＠indiana.edu

I'm convinced that my house was built over an Indian burial ground. Or it was owned by someone heavily invested in everything but DEC... I powered up my AlphaServer 1000A last night and it looks like it has problems too. It powers up and the drives & fans spin up. The lcd showed 'ec.' only once, every other time it is blank. Nothing out of serial port 1 and the onboard VGA never initializes. I tried setting the 'failsafe boot' jumper and I put a blank floppy in the drive just to see if it would try to read the floppy and it didn't even try :( Any ideas at all? So now it looks like both of my alphas are shot (the PWS500au never initializes video, does anything with serial, and turns off all diag lights) and my DECStation 5000/120 has a bad power supply. On the plus side, all of my terminals still work and both of my vaxes (MicroVAX 3100/90 and VAXStation 4000/90) boot to VMS without problems. It brings me to a question: are the alpha systems inherently fragile? The dead DECStation is an obvious hardware issue due to (probably) a leaked capacitor which is understandable due to its age, but the Alphas are just hosed in a software kind of way. Brian

WTD: 0.156in 2x10 or 1x10 edge connector for Motorola/Displaytek M1000-355 CRT

by classiccmp＠philpem.me.uk

Hi guys, I just picked up a Motorola M1000-355 CRT monitor (5in diagonal open-frame industrial "thing", circa Jan 1987 so almost as old as I am!) at the hamfest today.. Problem is, I don't have a suitable mating connector for the card edge connector... It's a 10-pin single-row card edge connector, with a 0.156in pin pitch, although I suspect a dual-row (20 pins total, 10x2 layout) would work fine too. These are listed as "US stock only" or "Discontinued, obsolete" by every supplier I've tried... Does anyone have one squirrelled away in a box somewhere which I could buy or have (he says with a cheeky grin) ? Or possibly a lead on a source for one or two of these, ideally with keypins (but the latter isn't essential)? I'd also rather like a copy of the datasheet for the monitor module if anyone has it... I have a pinout (it's the standard 10pin pinout as posted by Tony Duell quite a while ago -- IIRC either the Kaypro or Osborne monitor uses the same pinout) and a sneaking suspicion that it's CGA-spec, but no hard proof. I do know that it pulls 12V DC at about an amp -- the first value is printed on the PCB, the second was provided by the meter on my bench supply!

Soldering stations - OKi-Metcal, Pace or something else?

by classiccmp＠philpem.me.uk

Hi guys, Well, we've got a thread on desoldering kit, so I'm going to start one on soldering stations... :) It seems my love-hate relationship with my Antex 660TC soldering station has finally become one of almost pure hate. I sat down to assemble a couple of DiscFerret boards tonight, and after about 40 minutes the handle of the iron was too hot to hold. Tried again with the other iron, same story. If I hold it any further back, then the whole thing is completely out of balance... So I figure it's time for a change. Hopefully to something which won't try and roast my fingers. I've narrowed my choices down to two manufacturers -- OKi-Metcal and Pace. This is basically because they're the only two "professional" brands Farnell carry (I did look at some of the Weller soldering stations but they don't look much better than the Antex). I'm looking for something that'll suit SMD work -- ideally one which has "mini-wave" soldering iron bits (aka "hoof" bits) easily available, and is designed for lead-free work. I do run an SnPb line as well, though I'm slowly phasing it out (once I run out of 60-40 solder, which might take a while...!) At the moment the front-runners are: - Pace WJS100 (with TD-100 and Instant Set-Back aka auto-standby). Not overly keen on this one, seems overpriced when compared to other Pace kit (especially when you consider that the WJS only works with certain soldering bits and one type of handpiece) - Pace ST50 + TD100. Seems about the same as the WJS100, but will run the tweezer handpiece and a wider variety of bits. Catch is, I'd have to special-order this from Pace UK if I wanted the ISB option (Farnell don't stock the ISB "cubby" / iron stand). - Metcal MFR-1110. Cheaper than the Pace (or so it would seem), cheaper tips. Also seems to have "auto standby" as standard. What concerns me is that it seems to run at a fixed temperature, though OKi/Metcal claim that SmartHeat makes this a non-issue... I'm not convinced... Has anyone used any of the above, or anything similar? Are there any other brands (or other soldering stations from the above manufacturers) that I should look at? Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
