I have 2 different loopback? plugs... both made by T-BAR 565-980-2 is DB25M with wiring (on the visible circuit side): 2-3 4-5 6-20 8-23 11-15 12-21 14-16 565-980-3 is DB25F with wiring (on the visible circuit side): 13-19-22 17-24 There are traces on the top of the PCB as well, but the DB25 connector is covering them, so they'd have to be discovered via a multimeter.... I haven't found any t-bar information by those #s on line.... And they don't match a few different RS232 loopback plug wiring diagrams I found online... Anyone have a clue what these are ? Thanks, -- Curt

However, the symptoms were different - there was activity on the display and there were beeps giving error codes. I have also had a problem with a failed Bcache on the CPU module (it seems this can be a weak point on the AS1000A) and I had memory failures. However, neither stopped the POST displaying on the LCD nor the graphics console from working. I would suggest reseating the CPU module and removing any PCI cards present. (I have an Alphaserver 800 which became a complete brick while a combination of PCI cards were present that it didn't like.) If there are any EISA cards present, I would leave them in place because there may be issues with the config utility that has to be run when the EISA bus configuration is modified. Other than that, I suggest trying the system with just the bare essentials present and seeing what happens. It would be useful to know if the fans start. Fan problems on some alphas cause the whole thing to shut down. Also, there is an interlock microswitch to prevent power up when the cover is open. This is probably not the problem here though as the symptoms are as if the front panel power switch is off. Regards, Peter Coghlan.

A huge chunk of Gopherspace up for download

AlphaServer 1000A not booting

Andrew Warkentin wrote: "I know that the motherboard is receiving power because the "link active" light on the Ethernet adapter comes on." I hate to tell you but the ethernet boards led's come on anytime a cable is plugged in that is connected to other related equipment - a hub, switch, or another computer via a "null-modem" cable. It does that even with the power cord unplugged. Do you have any of the manuals for the 1000A? I have manuals for the Alphaserver 1000A if they might help. Good luck!

Low level formatting an Apple Profile hard disk

by ian_primus＠yahoo.com

I'm looking for the requisite ROM image and software to low level format a Profile 5mb hard disk on an Apple III. From what I've read, I need a 2k ROM plugged into a Zilog Z8603 that replaces a chip on the controller board, and format utility booted from floppy. So... Does anyone have this software? Burning an eprom and writing a disk are not a problem - I just can't find the ROM image/software anywhere. -Ian

Dysan PAT-2+ Performance Alignment

by billdeg＠degnanco.com

I recently came upon a Dysan PAT-2+ Performance Alignment Tester and I already had an alignment disk for it - an 8" 48TPI 360 RPM 2 Sided drive - disk 360/2A. Does anyone have a source for additional format disks? Each drive type has its own disk. What's on these disks anyway? My PAT-2 does not power up at the moment, I have to open it up and take a look to see what's the problem. Hopefully it's just a voltage regulator. I checked the web, too many Dyson vaccum cleaner links and non-relevant stuff. Bill Degnan

i8355 from SDK-85 flakey

by chrise＠pobox.com

I obtained an Intel SDK-85 eval board some time ago and decided to try to bring it back to life today. It had been part of a Philips logic analyzer demo system apparently. They had cut off the prototyping area on the left side and put their own board there instead... which had a 2716 EPROM on it and some hardware to generate glitches as part of the logic analyzer demo I guess. In any case, I undid all of their mods (except of course, putting the sawed off prototype section back on!) and the unit sort of works. What I have discovered is that the 8355 ROM+IO chip is flakey. It won't work unless I freeze it with component cooler. Once I have done that, then it starts working and stays working for hours as long as power is not removed. If it gets powered down, then I have to freeze it again before the device will respond with valid fetches. I don't suppose anyone has a spare 8355 with SDK-85 monitor burned in it do they? I'm guessing that's probably unobtainium so, failing that, wondering if there's a .HEX of the ROM image floating around so that I don't have to type it all in. If I have the bits, I can burn a 8755 that drops into the same location. Any guesses as to what the failure mode might be of the 8355? It is sort of curious that once it gets started from frozen, it keeps working nicely. I already did my time at ETA, cooling chips in liquid nitrogen so that's kind of behind me now ;-) Chris -- Chris Elmquist

the beginning of the end for floppies

by c.murray.mccullough＠gmail.com

I think we are beyond the beginning. The end of floppies began several years ago when notebook manufacturers no longer built them in. Netbooks the same. Another technology has bitten the dust! It appears if I will have to transfer the data on 100s of floppies unto usb thumb drives. Hopefully they will be around for some time to come.<fingers crossed> Murray--

AlphaServer 1000A not booting

by andreww591＠gmail.com

I have an AlphaServer 1000A 4/266 that is not booting. When I power it up, nothing shows up on the control panel LCD and there are no beep codes. I know that the motherboard is receiving power because the "link active" light on the Ethernet adapter comes on. Is there anything that I can do to fix it, or should I just try to find another Alpha (I don't seem to have much luck with Alphas - I have a DEC 3000/300X with a bad RAM slot).

low cost prototype PCB vendor?

by dj.taylor4＠verizon.net

In the latest IEEE Spectrum magazine there is an article on page 24, 'Hands On - Why stop at breadboarding when custom PCBs are easy to design and cheap to get made?', by James Turner. Summary of this: He used Eagle to design/layout the board (which seemed to be free), you have to do the trace routing manually, and your pcb is 'batched' with others to keep the price way down.

Memorex 102 20MB Hard disk

by snhirsch＠gmail.com

Has anyone on the list seen or work with one of these? I received a Morrow M-20 8-inch hard disk along with my N* Horizon and found the Memorex 102 disk mechanism inside (what a beast!). At initial power-up, a 10-ohm 5W resistor near the power connector let out a puff of smoke (the drive was in the process of spinning up). I killed power and started checking components carefully. There were no ominous readings across the 5V logic power rails and I traced things out enough to determine that this resistor was between the +24V power input and whatever lies downstream (probably motor servo). The platters move freely, so the motor certainly wasn't bound up. When I checked power supply voltages (it's an analog supply), I discovered that the +24V rail was delivering +44V (!) and the -12V rail was -15V. The 5V rail was right on spec. For a quick reality check, I plugged the supply into my bench variac and adjusted input voltage to yield +24V at the motor supply. Both other rails were within spec at this point. When I tried again to spin the drive up at the correct voltage, the series resistor became extremely hot although, again, the drive was on its way to full rotational speed at the time. I measured 20V across the 10-ohm resistor, which calculates to 2A and a dissipation of 10W. The latter number explains the heat. Not wanting to tempt fate, I shut things down quickly. So, opinions and suggestions please? A two-amp draw does not seem excessive to me, although clearly it's outside the design parameters given the rating of the dropping resistor. The power supply is certainly reparable, and before anyone asks it is delivering clean DC - ripple is on the order of 10mv. Why it's doubling its output is yet to be determined, but I did find a diagram at bitsavers. One thought that occured to me is that the +24V rail is probably powering the voice-coil positioner in addition to the motor. I felt around extensively, and none of the power devices involved with head motion or servo is excessively warm. None of them appear shorted or open. Not sure where to go from here. Steve --

I didn't know that TI made small hard drives of that era, interesting. Thinking of old hard drive manufacturers... Was CMI actually making drives back in 1981? They were in Southern California like XCOMP. By the time I saw CMI drives (1983? 1984? PC-AT days) they were being made in the far East in large numbers, and the stepper was on the outside of the housing, but maybe CMI made some drives domestically before that. Tim.

I was hoping he could create and sell a case/interface kit without the modern motherboard, but since the case was part of an old function generator(?) he purchased on eBay, a similar case would have to be mass produced which I suspect would be prohibitively expensive in small quantities even if produced in China. If a case kit like this was in fact made available at something approaching a reasonable price, I'd buy one in a _heartbeat_. Typical "case mods" hold no attraction for me whatsoever. One like this definitely would.

Unsticking an RD53

by robert.jarratt＠ntlworld.com

A while ago I posted about an RD53 I have which had the problem with the sticking heads. I have now got to the point where the heads no longer stick on the bumper, but the disk still does not work correctly. I opened it up and watched what it did with the cover off. Once it gains speed it moves the heads out all the way and then they just stay there with the disk spinning. There is a whine coming from the drive, not sure of the source of this though. Is this the right head behaviour? Below is what I got when it was installed in a MicroVAX 2000: >>> test 50 KA410-A V1.2 ID 08-00-2B-07-98-90 ? CLK 0000.0005 NVR 0000.0001 ?

But the verifier just stuck on there and did not show any progress for a good 20 minutes or so, I believe an RD53 should verify in about 8 minutes. Any suggestions? Thanks Rob

PPC 601 and mftb/mftbu

Hi Cameron, > I'd sort of independently determined this, although I settled on mfrtcu > which is spr4-5, IIRC. I'm not sure if it's high enough resolution for this > task, but as you point out, rdtsc() in the PPC nanojit is a function, so > it may not be a significant problem. mfrtcu/mfrtcl *should* work on the 603 > and up, right? I'm not so sure. I had a look at the rtc. Although I think there's user-level access for both the 603 and 601 etc, the problem I see with using it is that rtcl counts MOD 10^9 and I'd guess that the use of rdtsc assumes MOD 2^64. -cheers from julz @P

PPC 601 and mftb/mftbu

by julianskidmore＠yahoo.com

Hi Cameron, > Anyone know of an equivalent for 601 that will still > work on 603+? Or am I as dead in the water as I suspect? The rdtsc function has its origin in the rdtsc instruction on an x86 CPU, it returns a 64-bit value, the number of cycles since power on. I can see from the rdtsc function for PowerPC that it is implemented using a routine, so it's exact performance isn't critical I would presume. The nearest instruction on a 601 is mfspr rd,6 which loads the decrementer. This is a user-level instruction on the 601 (not on the 603 or later). So, -DEC roughly the tb. According to the Ppc601 user manual, dec uses the 7.8125MHz RTC clock as its time base (pg H-3), but on page B-8 it says the power architecure decrements dec every nanosecond. So, we could do something like: static __inline__ unsigned long long rdtsc(void) { asm { mfspr regUpper,6 }; return (long long)-regUpper<<32; } In this case, the effective frequency of the clock is 7.8125MHz*2^32. For the PowerPc601. On initialisation I would probably read the processor version register (PVR) to determine the processor; and if it was a 601 I'd substitute the PowerPC 601 code and then flush the code and data caches. -cheers from julz @P

Hi folks, I'm currently dealing with some RK8E Omnibus RK05 controller board sets. I was unable to assemble even one stable RK8E from the stuff. I assume a high failure rate. But I also assume that I have board revision problems. I've been told that several revisions existed. And that there were compatibility issues and some kind of paper (which I do not have) telling what fits what. I don't even know if the revisions are PCB revisions like "M7104 B2" written in the etch or if there are also FCOs or alike that make boards with same etch incompatible to other boards. My personal RK8E passes all tests. It consists of: M7104 B2 M7105 B1 M7106 C But I have other boards flying around here as well. Do stamps like "310 D" on the backside of the boards have any meaning with respect to board revision or FCO level? Another question is how to get different board revisions associated with the right schematics. I strongly appreciate any piece of enlightenment since I'm currently getting depressed by that stuff. Even if I have bad boards - it won't make sense to try to repair something if the whole is inconsistent in itself. Many thanks, Philipp

PPC 601 and mftb/mftbu

by spectre＠floodgap.com

Okay, old PPC hands, here's today's challenge. I finished porting SpiderMonkey (the pure C JavaScript reference implementation) to Classilla, which is the web browser I maintain for classic Power Macintoshes in OS 8.6 and 9, and it works great. So, for an encore, I decided to see how feasible porting TraceMonkey would be, which precompiles selected portions into assembly using a "nanojit." I started working on translating the inline assembly into CodeWarrior, but CodeWarrior did not like my conversion of their "rdtsc" function, which uses the mftb/mftbu instructions. The reason is that I'm compiling for 601, and CodeWarrior will only assemble those instructions for 603 and higher. Anyone know of an equivalent for 601 that will still work on 603+? Or am I as dead in the water as I suspect? Mind you, I don't even know if the rest of this will work on 603s or 604s, so this might just be the first of a whole mess of problems. I wasn't sure if it would work in the first place, and SpiderMonkey already cut Classilla's JavaScript execution time in half, so it's not like this is a catastrophe. Still, I'd love to get JIT compilation working if I can. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- If the dictionary misspells a word, how would you know? -- Steven Wright ---

Rusty pdp8/e chassis anyone?

by hachti＠hachti.de

Hi folks, today I slaughtered a pdp8/e computer. The guts will go into further use and repair of other machines, but the chassis underside is still there. As I have no use for it I'm offering it as free for everyone. It's just the lower part of the chassis. There's no Omnibus, not PSU, no nothing with it. And it's really really rusty. That's the reason why I decided to dismantle the system. If anyone is interested, let me know. The chassis could be brought back to life via sanding and repainting. Local pickup (northern Germany) preferred, shipping possible (but seems to be quite useless). Regards, Philipp

low cost prototype PCB vendor?

by lynchaj＠yahoo.com

http://classiccmp.org/pipermail/cctalk/2010-April/285344.html [snip] >Can you relate your issues with Advanced Circuits, just so others who >might want to use them might be able to take it into account? > >Jim Hi Jim! Please don't get me wrong, I *like* Advanced Circuits and they've been great. I wish I was wealthy enough to do all my boards with them and surely would were I in business. Of course, the N8VEM project and the S-100 boards with John from S100Computers.com are basically self funded hobby projects and on "shoe string" budget. I really can't afford AC's premium quality boards though I wish I could. The trouble is with my ability to order boards from the AC website. Their special deals are internet only which is fair but when I try to upload my files to the AC website I get errors and cannot complete the order. The people at Advanced Circuits have been great and I have no complaints but for the last few orders I've had to call them and basically "finesse" my orders into the system using phone calls and email. I can see that is going to get old quickly and soon AC will run out of patience with me. Then I am screwed and need a new way to get prototype PCBs. I've worked with their IT people and the local sales rep to figure out the problem. They say the file upload connection is timing out someplace like there is a bad link between my network and theirs. The weird thing is that I can upload files to freeDFM.com which is also an AC free service as much as I want and it works reliably. Frankly, the whole problem makes no sense to me. Thanks and have a nice day! Andrew Lynch

MicroVAX 3100 Model 40 and 8MB memory modules

by robert.jarratt＠ntlworld.com

I have a set of 8MB memory modules. Installing any two of these the Model 40 will recognise 16MB. If I install a second set in the second set of slots it only recognises 24MB, but I am sure that one point it recognised them as 32MB. Is it possible that my memory is not serving me correctly, do the second and third pairs of slots only support 4MB modules? Thanks Rob

Anyone know anything about Infoton terminals?

by derschjo＠mail.msu.edu

Picked up an old terminal today (even though I'm *supposed* to be slimming down my collection... sigh). Just couldn't resist. Its only identifying marks either internally or externally are the name "Infoton". There does not appear to be a model designation. I've put up some pictures at http://yahozna.dyndns.org/scratch/infoton/ (warning: large images) Logic appears to be TTL, there is no CPU as far as I can tell. Date codes on ICs are from '72-'73, and one of the boards and the keyboard PCB have labels indicating "12/73" so I assume this particular model is >from late 1973. It appears to talk current loop and RS-232 but I have no idea what the wiring for the connector is (or even what *kind* of connector it is -- see the pictures above). I haven't had a chance to clean it up yet, but after a bit of contact cleaner on the power switch, it appears to work fine, at least in local mode. Seems to do 80x24 chars, uppercase only with underlining. Infoton shows up in termcap/terminfo entries, so that's a good start... Anyone know anything else about this beast (history, tech specs, etc?) I believe, from my research thus far, that Infoton later became General Terminal. (General Terminal is rather hard to search for on the 'net due to it being a fairly common phrase... so I'm not sure how helpful that's going to be...) Thanks as always, Josh

I'm running UCX 4.0 and my UCX experience is limited, but on my box "HELP TCPIPTRACE" is the place to start. For today's problem, however, it's unlikely to help as you'll see an attempted connection and a failure (SYN from PC, RST from VAX at a wild guess). It might be worth a shot as it might show that the initial connection works and something goes wrong later on. > If I try to run UCX FTP on the good VAX to connect to the bad > VAX this is what I get: > >> conn 192.168.0.106 > %TCPIP-E-FTP_NETERR, I/O error on network device > -SYSTEM-F-REJECT, connect to network object rejected That sounds like nothing is listening for FTP.

Can you FTP >from the same windows machine to any other FTP server? I vaguely remember a problem with the VMS TCPIP wanting to do a reverse dns lookup of the client making the connection and this holding things up for a while if it did not complete due to lack of access to dns servers etc. However, I don't recall it causing the connection to fail. > > ISTR, isn't there an option for command line FTP to disable/enable >local echo, or something to that effect?

Many of the GUI FTP clients for windows assume a unix or windows filesystem on the server and completely fail to cope with the syntax of VMS filenames. Even the ones that claim to understand VMS can still run into difficulties. I think part of the problem is that the RFC describing FTP says that filenames should be in the servers format rather than in a platform independant format and the GUI FTP client producers tend to do what they think should work rather than follow the RFCs to the letter.

More stuff to get rid of - Seattle, WA

by derschjo＠mail.msu.edu

Time for some early spring cleaning. I've got a pile of stuff I'm never going to use again (I've decided to give up on my SparcStation collection, for example :))... Here goes. This is all located in the Seattle area, the smaller stuff I can ship but I'd of course prefer local pickup. Make me an offer... Anything not claimed will be put on Craigslist at the end of the week and the remainder goes to RE-PC after that. - DEC RL02 : not working, but is complete (minus front panel bulbs). Very beat up looking, but clean inside. - Acorn A5000 : works, but faceplate is beat up (got mangled in the mail due to bad packing). Needs new battery (removed old leaky one before it could do any serious damage). No keyboard/mouse -- not PS/2 compatible. - IBM PS/2 Model 70 (386). 4mb ram, no hard drive but sled is present. Boots just fine. - Blue & White G3 Mac with 450Mhz G4 upgrade. Runs fine, no hard drive, somewhere around 256mb of RAM. - HP Apollo Series 700. Small pizzabox. Worked the last time I powered it up. - Amstrad PC1640 SD : just the main unit, no monitor (which supplies the power). Missing one of the drives. - Beehive "Super Bee" terminal : No keyboard, needs repair. In solid shape. Heavy. - 2x IBM PC Convertibles : One has a backlit screen, one without. Two carrying cases. One AC adapter. Serial and Printer expansions. - Sun Ultra Enterprise 2 : Dual UltraSparc IIi, 512mb ram. No drives, but I have sleds somewhere. - SparcStation 2 - 2x SparcStation IPX - SparcStation IPC - 2x Macintosh Portables - good for parts, no working hard drives between the two, alas. (None of the SparcStations have working NVRAM batteries.) - Piles of old IDE disks (500mb or less). Unknown condition, many were working at one point but time and stiction make fools of us all. Inquire if you want details, I'm too lazy to list them all here right now :). - IBM P260 21" CRT monitor. Nice flat trinitron CRT, works pretty well. Large, as these monitors tend to be. Does SOG.

FTP from Windows to VMS

by robert.jarratt＠ntlworld.com

I am trying to run the ftp command on Windows (7) against an FTP server on VMS 7.3 (the UCX version of TCP/IP). I am sure this has worked in the past, but now when I try it connects successfully but VMS never sends back the login prompt. I tried running FTP on the VMS system back to itself and the prompt came straight back. Sniffing the packets I see a SYN from Windows, SYN-ACK from VMS and then ACK back to VMS. 60 seconds later Windows resets the connection. Has anyone else seen this and know the solution? Thanks Rob

Stuff to dispense with pt 1.

by pat＠computer-refuge.org

This is what I'm attempting to get rid of from my warehouse. I would like to get something for the machines, but mostly want to make sure that the stuff doesn't get scrapped. Everything is assumed to work, but I have no guarantees that it does, and it hasn't been turned on in quite a while, but it has been stored in a climate-controlled warehouse. I'm open to some trades, and negotiable on prices for most stuff. I'm not willing to ship anything myself, but may be willing to drop it off somewhere to be shipped - I mostly don't have time to pack this stuff. Email me for more info on any of this stuff. For the most part, this stuff needs to be gone by May 14th- when I leave for Dayton Hamvention. I may be able to bring smaller (desktop box) stuff with me, but larger stuff I won't be able to transport to the show with everything else I'm bringing. Some of the stuff will start disappearing at the end of next week via scrap or eBay if I don't hear anything by then. + VAX 8700 w/ TU-81+ and SA482. Haven't had a chance to power up, and will keep this if I don't get a good offer. Want around $500 for it. + DG Nova 2 w/ PERTEC 9-track tape drive and dual 8" floppy. Asking $750, this will go to eBay if I don't get any takers. + DG Nova 4. Have 3 or 4, some missing the front-panel. 3rd party Disk/QIC tape rackmount box that goes with them. + BA-11 10.5" tall UNIBUS expansion boxes. $25 each + SGI Onyx prototype machine. The same size and chassis as a Challenge XL. $100 + PDP-11/23 w/RL02s in corporate cab. $200 + RM-02 drives. I have 4, want to keep at least one. Never had much luck getting them to work with my RH-11 on my 11/84, but I don't think there's anything wrong with the drives themselves. $200 each + VAX 4000/200. I have two or 3 of these. $100 each + DEC CMR53. 2 of these. A pdp-11/53 system with some special communications cards in them. $100 each + AlphaServer 4100. $20 + Various VAXstation 3100s for whatever I can get for them + 4 tape drives from IBM 3480-B22 tape units. I've considered saving this for spares, but I'm not sure I care enough. + IBM S/390 G5 coupling facility. I'd really like to find the replacement software for the SE to make it into a "standard" CPU, so that I can at least run Linux on it, but I'm not sure that's likely. $200. + Encore Mulitmax UNIX box. 32 x NS32332 processors and 128MB ram, and a 2nd rack with a 9-track tape drive and some 8" hard disks. $250. + General Automation SPC16/40 and 16/45. Missing the front panel for one of the two, have an I/O box, and PSUs. needs some repair work. One of the PSUs needs new capacitors. Will keep unless I can get $500 or so for the both of them. + HP 1000 E-series, I think. Two of these. $200 each? + IBM RS/6000 SP. I've got one frame with quad-375MHz POWER3-II thin nodes, and one high node (16GB ram, 16 x 375MHz). $200 + DEC VT240 terminals. Probably 10. $5 each + IBM 9343-C02 DASD box. I have someone interested, but haven't heard >from them in a while, and am not sure how interested they really are ... I'd like to get $100 for it. + Two Amiga 2000 Video Toaster boxes. I may end up keeping one. $100. + Various IBM UNIX desktop systems, desktop VAXes, etc. $5 each. + Altos 8000 and 8600 systems. $10 each. + Tektronix 4010 terminal. $100. + Tullamore/Victoreen SCIPP 1600 1600-channel pulse-height analyzer. Powers up, but not tested much more than that. Looks cool, and has CORE memory inside. $50. Some pics I took a while ago: http://www.flickr.com/photos/vax-o-matic/sets/72157622536984302/ That's all I can recall for now.

classic computers at notacon7

by keithvz＠verizon.net

So I got back from Notacon7 in Cleveland, OH, yesterday, and wanted to mention that there was a classic computer presence there. Robert & Jim from Fresno Commodore User Group were there and had setup a variety of old machines including 64's, VIC-20's, 1541's, and even an A500(Yay!) with a couple boxes of disks. There was also a demo in the BlockParty demo competition from a guy who used the Coleco as his platform of choice. His demo was mostly written in Z80 assembly with help from some FORTH tools. There was a preference for running these demos on the old hardware. Plenty of Amiga "trackers" used during the music-only portion of the competition. http://www.demoparty.us/ and http://www.notacon.org/ has more info if you are interested. Keith

It appears that there has been a lot of interest in the Tek 4010 terminal. As I don't want to pick anyone myself, I think that I'll end up putting it up for sale on eBay and let everyone settle who gets it that way. I'll see if I can get it listed early this week.

HP Integral questions

by ard＠p850ug1.demon.co.uk

I've been reading the HP Integral service manual that Al kindly put on Bitsavers [1], It's a strange manual in that it includes schematics of the main logic boards. Why, I don't know, other comtemporary HP computer service manuals didn't. Not that I'm complaining... Anyway, various thoughts occured to me as I remember some thignn about that machine 1) Did HP ever produce the CS/80, SS/80 or Amigo drive exerciser software to run on the Integral? It seems it would be the ideal machine for use as a drive tester since it's so easily portable. 2) The later version of the OS ROM module has a space for an option ROM PCB. It seems like this would be trivial to recreate (schematics of the ROM Mmodule, inclding the pinouts of the option board connectors are certainly in 'my' Integral schematics). If enough people are interesd, it might be worth laying out a PCB... 3) The manual mentions that the Integral expansion bus was an implementation of some other HP standard bus, but only rows A and C. What other machine(s) used a similar bus? I can't think of any. [1] I've also been reading the HP9000/200 Pascal 3.0 system docuementation. A wonderful mine of information, but oh so annoying to read on a screen... -tony

UCSD p-System hoard to disperse

by jfoust＠threedee.com

I've been contacted by a former software developer with extensive experience with the UCSD p-System on several platforms. He'd like to dispose of most of his equipment and documentation. I'd like to help him find a new home for it all. I'm not quite sure how to do that, but it might depend on who else is interested. Please contact me if you are. He is located in southern Illinois, USA. I am located in southern Wisconsin, about six hours away. I'd like his spare Terak 8510 system and a Cipher 9 track. There are two PDQ-3 systems. I am tempted to take one, as it is closely related to the Terak. These are LSI-11 with Western Digital microcode to run the p-System directly. They include 10 or 20 meg hard drives. They are circa 1982. I think they're rare. The only mention I find is on a UC-Irvine web page, although I've emailed with someone who worked at the company that made them (Advanced Computer Design?). One of the hard drives might contain some source code from ACD. He used these for software development. I've found references that say these systems were used to develop in Modula 2 and FORTRAN. They competed with the Sage. There's an Atari 1040 ST running the p-System. There are four or five 68000-based multitasking multiuser Pinnacle Systems (later Logic Process) systems. These drove 8 to 16 users on Wyse 50 terminals. They are circa 1983. One is the bigger unit with more horsepower and an internal tape drive. There's two Corvus Omninet drives, with various junction boxes, cabling and interface cards - perhaps for PC, Apple II and maybe Q-bus. There's a bunch of p-System books, newsletters, etc. as well as software. He was a USUS member. There's a VT 220 and several Wyse 50 terminals. I might want the 220. It sounds like there's lots of software going all the way back to a copy of Wirth's CDC compiler. - John

Use mini CDR for equipment info?

by cclist＠sydex.com

Dear List, Some bits of equpment that I have get hauled out only rarely and I often waste a lot of time identifying them then trying to remember where the heck I put the paper that describes their operation--and then locating the disk with the related driver information. I've been considering archiving the information on mini (200MB) CD-R and taping said CD-R somewhere nside the equipment. Mini, mostly because their physical size is convenient and I rarely have more than 200MB of information on any peripheral. Does anyone else do something like this? I have little experience with mini CDR--are they reliable? Best reagards, Chuck

I use KiCAD quite a bit and have designed several PCBs with it. It works fine and is completely unrestricted. I think it is a fine product and recommend it whole heartedly. It has improved dramatically over the last couple years. Also, all of the N8VEM PCBs are posted on the wiki in the KiCAD format. Thanks and have a nice day! Andrew Lynch

Long shot: Burroughs C3360 schematic?

by derschjo＠mail.msu.edu

Hey all - Picked up a Burroughs C3360 calculator this week. It's a programmable 4-function+square root and 10-register memory with a nice 16-nixie display. (See http://oldcalculatormuseum.com/bc3660.html) I cleaned it out, and it's working fine in calculator mode, but in programming mode the program step counter is usually (but not always) stuck at zero. Sometimes it increments properly for a few seconds after power-up. Seems like a fairly simple fault to trace down, if I had any idea where to begin... anyone have a schematic for this thing (or the Sharp Compet 363P, which this machine is a rebranded version of)? Hopefully the fault isn't in one of the LSI chips in this thing, I'm guessing those are going to be hard to find. Thanks as always, Josh

DEC RK05F videos and pictures - running it naked!

by hachti＠hachti.de

Hi folks, here are some videos and pictures I took when operating an RK05f completely open with the exposed. Hope you like it! http://pdp8.hachti.de/?gallery/rk05f And keep in mind: I did this for curiosity and the whole thing only lasted a few minutes. The disk is back in the plastic shroud and nothing has been ruined. In fact the drive was still not 100% perfectly adjusted while I shot the stuff on the page. In the clips the drive performs part of the DEC maindec drive control test. I had a lot of trouble finding out the servo system's weakest part.... Now I managed the drive to run reliable and to be able to retract the heads properly (seems to be not so uncommon problem!). Best wishes, Philipp -- http://www.hachti.de

Terak disk update

by cclist＠sydex.com

List, Just for the "FYI" file, Terak (UCSD Pascal) floppies appear to be either SSSD 3740 format (FM 77 tracks * 26 sectors * 128 bytes) or SSDD (Track 0, FM 26 sectors * 128 bytes, not used) 76 tracks * MFM 15 sectors * 512 bytes. The double-density format is definitely standard MFM, not DEC RX02 (FM headers, "tweaked MFM data). The MFM format is interleaved 2 to 1 with a one-sector skew per cylinder. The FM format is also interleaved 2 to 1 with a 6 sector skew per cylinder. For whatever it's worth, Chuck (P.S. I wouldn't mind owning a Terak, judging from some of the program code I've seen).

New old products :)

by geoffr＠zipcon.net

I?ve gotten back into my Atari systems again and since I had a couple Indus GT drives, I found a schematic for the RAM upgrade board for the drives, and had PCB?s made :) my first professionally produced PCB?s in 20+ years. I?m quite pleased since it was a first effort with new software when I hadn?t touched EDA software in 20 years or so. Lessons learned were: Increase PAD size :) these are solderable, but are just a touch too small by the software default. Validate that pin one indicators REALLY render out to the gerbers. I have to refer back to my PCB design for pin one since it didn?t render. Quadruple check that all wires and nets are present. I discovered that a trace between 2 pins on the connector(s) disappeared on me at some point during editing, it is entirely possible I deleted it like an ID10T. So for this run of boards, wire-wrap wire will be my friend to jumper the 2 pins at the PCB.

Searching Sage-IV ROM 2.0/2.1 dump

by holger.veit＠iais.fraunhofer.de

Hi, I already asked this in thesimh mailinglist, without replies, so maybe this list is more appropriate to get a response. I am working on a SIMH emulator for the Sage&Stride 68k machines (Sage-II/IV). There is a lot of docs available at sageandstride.org, which is the base for the development. One thing I haven't found yet is a more recent boot ROM than the available 1.2 version; docs mention 2.0 and 2.1. These versions have, besides presumably a number of bug fixes, support for the winchester disk card. Does anyone have a rom dump (any format) of such a BIOS (16k)? I already tried to contact David Erhart, the owner of the above site, but twice didn't get any response. Thanks in advance Holger P.S. The code is not yet ready to release (still some bugs in the FDC part, some missing instructions, and the HDC support), but I'll report in the simh developers list when it is.

Electric Dreams (UK'ers only)

by aliensrcooluk＠yahoo.co.uk

Hi, I happened to catch the last 20 minutes or so of the programme Electric Dreams, which appears to be on for the next few days on BBC2, starting at 7pm. A family have volunteered to see what life was like in the previous decades (70's, 80's, 90's). That is to say old modern tech in the house and home has been replaced by old tech - so no X360 or PS3 for the kids! Tonight's episode was about the 70's and included a short scene with Sir Clive Sinclair, a Sinclair calculator, an old Sinclair TV advert and a Commodore PET - the father was trying (and failing) to do his day-to-day work on the PET! Here's a link to the BBC site for those that can access it: http://www.bbc.co.uk/electricdreams/ Tomorrows episode is going to be about the 80's, and will include a BBC Micro among the 80's tech.

by ragooman＠comcast.net

Did someone have a hack for 8" or 5-1/4" drives using a Flash drive ? I like to build one to troubleshoot floppy controllers without risking damage to the original drive. There's one from Germany for about $300 but it's too big for my wallet. http://www.ipcas.com/products/usb-floppy-emulator-fdd-to-udd.html I'm trying to fiddle with my google search terms but nothing points to a homebrew version yet. =Dan

OT: Weller WTCPT owners

by cclist＠sydex.com

A little tidbit for you owners of Weller WTCPT irons with TC201 handsets that take the EC234 heaters. If your old heater was made before 2002, be sure to also buy a new BA60 sleeve and nut. The newer EC234 is slightly wider and won't fit the old BA60. Just something I discovered to file away for a rainy day. Cheers, Chuck

I don't see a Linux or Mac version, so it's a non-starter. I'm not going to dork around with Wine to use an EDA tool; I'll just stick with tools that work natively. >> I use Eagle because it works on any computer I'm likely to be sitting... I stand by that - Eagle works on Macs, Linux boxes and Windows boxes. I don't have to worry about the platform in front of me - there's an Eagle for each one. > I do believe in Diptrace.

Perhaps it's advanced enough for a second look. -ethan

A 10 ohm resistor would limit the inrush to 2.4 Amps with zero spindle motor resistance. Given the 112 has an inrush of 4.5 Amps, this further suggests this is not a 102. I have a disassembled 101 in my garage if that would help and I can find it Tom

worn edge fingers

by dgriffi＠cs.csubak.edu

I was examining some old Vectrex cartridges and I noticed on one that the gold on the edge fingers has worn down to the copper below. What's the proper way to rehab things like this? Wipe with some solder and blow off the excess with an air compressor? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Hmm... that would have killed my last project - a PLCC-44 89C52 (that we later swapped out for an ATmega8515 with no board changes required) and 5 ICs total ('541, 2x ULN2003, '14, MCU). Went fine with Eagle except for the holes for the power jack and my goof on the Port D bus. Autorouting worked for 75% of the project, and manual routing is not tricky. The first test program ever loaded into the board ran the first time (blink LEDs on two port bits). I'd call that a success. -ethan

pdp-11/35 on Ebay UK

by julianskidmore＠yahoo.com

Hi folks, Looks like cctech's missed this one, but there's still several hours to go! There's a pdp-11/35 being auctioned on Ebay uk: http://cgi.ebay.co.uk/DEC-PDP-11-35-with-EIS-and-Core-Memory-PDP-11-PDP11_W… It's in Halifax; a mere 50Km from where I live! Unfortunately, I can't afford it :-( But I thought you might like to see what's going down oop North ;-) -cheers from Julz @P

WTB: SGI Professional IRIS CPU / Help Needed

by mailinglists＠lenerz.org

Hi there, I'm owner of a Professional IRIS 4D/50G made by Silicon Graphics some time around 1987. The machine has apparently some kind of trouble related to the CPU board. I'll include some details further below, I'm open to any good idea. Because of that problem I'm in search for a suitable CPU board. The failing board is a IP4 CPU board (part nr. 030-0121-001 Rev A). I presume that any kind of CPU board from a Professional IRIS line machine would help (mainly IP4 and IP4.5). Please drop me a note if you have a spare or can point me in a promising direction. As promised some details. The machine used to work fine once I had set it up quite a while ago. Recently it refused to boot and upon inspection I got the following error: ---- snip ---- EXCEPTION: <vector=NORMAL> Exception pc: 0xbfc108a0 Cause register: 0x30001008<CE=3,IP5,EXC=RMISS> Status register: 0x80000<CM,IPL=8> Bad Vaddress: 0xc0000000 Error Addr register: 0x17b40 Local I/O interrupt register: 0xff <> Parity error register: 0x0 Registers (in hex): arg: c98cf600 ffffffff 15180 0 tmp: 0 0 0 0 0 0 0 0 sve: a0017b93 bfc268c8 bfc268ca 1 54 0 1 800 t8 ff00 t9 502e8000 at 1 v0 c0000000 v1 f65da k1 bfc04234 gp 0 fp bfc04bd0 sp a0017b64 ra bfc10744 exit(-1) called ---- snip ---- This happens just after POST (I think) when the machine is either about to start IRIX or to show the PROM menu. Of course nothing further happens except that the error is repeated without end. I did strip the machine down to a bare minimum of boards (IP4 and Ethernet) and I also swapped the memory sticks. The only things I could reasonably pull in a last attempt would be the VME Ethernet board and the system disk. Regards, Gerhard -- http://www,sgistuff.net/
