All: If anyone is looking for a very simple, temperature-dependent fan speed control, check this out: http://www.heatsink-guide.com/content.php?content=control.shtml It uses a 10k pot, NTC thermistor, MOSFET and 12v fan. I just built one using a 40mm Sunon fan for a small SBC enclosure and it works great. All parts (except the fan) are available from Radio Shack and cost about $7.

Microfilm scanning - film scanners?

by philpem＠philpem.me.uk

Hi, I've been skimming the recent threads on microfiche scanning with some interest. Just out of curiosity, has anyone tried scanning microfilm/microfiche with a film scanner? Just interested, because VueScan (free trial from www.hamrick.com, $50 for the basic licence, $90 for the 'professional' licence) seems to have a setting for microfilm scanning. Unfortunately I don't have any microfilm to try it out, but my film scanner (a Minolta DiMAGE Scan Dual IV) only takes mounted 35mm slides and 35mm strip film, so anything I put in would have to meet those size constraints... I could (in theory at least) bodge up a cardboard carrier for my flatbed scanner (an Epson Perfection 2400 Photo) and use that, but I don't rate its optical quality for transparency film very highly. I was just curious if anyone had considered trying it... I'd love to but like I said, I haven't got any film to test with. -- Phil. | Kitsune: Acorn RiscPC SA202 64M+6G ViewFinder philpem at philpem.me.uk | Cheetah: Athlon64 3200+ A8VDeluxeV2 512M+100G http://www.philpem.me.uk/ | Tiger: Toshiba SatPro4600 Celeron700 256M+40G

Stumper: What computers are these?

by sethm＠loomcom.com

Alright, I admit it. I'm stumped. BBC has a series, "Look Around You", a comedy program based on late 1970s and early 1980s educational programming. Season two included an episode called "Computers", and featured these two fake "home computers". The Bournemouth ("The most powerful computer in Britain"): http://www.bbc.co.uk/comedy/lookaroundyou/wallpaper/images/1600/ bournemouth.jpg The Petticoat 5 ("The first computer designed just for women"): http://www.bbc.co.uk/comedy/lookaroundyou/wallpaper/images/1600/ petticoat.jpg I assume that these are genuine British classic computers that the producers painted and re-badged for television. But what are they? -Seth

Compaq Portable III

by reevejd＠mchsi.com

Hello All. I have a Compaq Portable III (286) that is functioning fine, except that the clock loses time (it seems to basically stop) if the machine is off more than an hour. It does remember its setup information, however, and there are no error messages during boot-up. I imagine it needs a new battery - where would I find one for such an old machine? The battery does hold a charge for at least some time, according to my meter readings, so maybe it isn't the battery? Thanks for any help. John R.

Root password on solaris 5.7?

by compoobah＠valleyimplants.com

> Solaris 9 is the last version to run on all 64-bit Ultras; Solaris 10 is >very impressive from a networking and virtualization standpoint (plus >ZFS kicks some serious ass) and is what you should be running if at all >possible. So where's your line between 9 and 10? I just moved from a U1 200E to a U10 333, and I stuck with 5.9 because I was concerned about usability on the U10. >All other versions can hit the road for all I care (unless >you need BSD SunOS 4.x for 1980s hardware). 4.1.1_U1 is definitely the one to use for Sun3, but I like 4.1.4 on my IPX (Sun4c) as well. Never tried 2.5.1, but 2.6 was very slow.

looking for info on the NCR Datamate

by chrism3667＠yahoo.com

Not the Decision Mate, something that probably came out after it, yet before the PC4/i. They all basically have the same appearance. I was talking to a former employee of NCR and she told me that less then 3000 were made. It was intended (says she) to be networked with the Decision Mate or something, and share some of it's resources maybe. __________________________________________________ Do You Yahoo!?

Airflow in drive case

by rcini＠optonline.net

All: I'm replacing the fans in a dual 8" drive case. The case has two distinct sections - the drive side and the power supply side - each with a fan. On the power supply side, air is being pulled through the case and out the back through a filter. On the drive side, the fan is the blowing in, with no filter. The cover does not have any ventilation holes. It appears that the fan on the power supply side is original but the other one was installed later (based on the wiring and the model of fan). Should the orientation of the fan on the drive side be changed? I would think that cool air (although unfiltered) should be pulled through the front of the drives and out the back. Thoughts?

RS232 <=> RS422

by julesrichardsonuk＠yahoo.co.uk

I've got some equipment here that has RS422 serial on it - i.e. it uses differential signal pairs rather than RS232's reference against ground. Question is, can I wire up a cable so that I can use an RS232 terminal with this RS422 equipment? (running over a short distance) Looking at the schematics, I think it's possible, with signals mapping to: RS422 RS232 RXD- GND RXD+ RX TXD- no connection? TXD+ TX CTS- GND CTS+ CTS BSY- no connection BSY+ RTS ... but I don't know if I should ground TXD-, or indeed one web site I saw suggested that TXD- should be used as the signal and TXD+ is actually the reference. I suspect that one or other should be left floating and the other pin of the pair forms the 'real' TXD in RS232-speak. Obviously I need to swap signals for communications to work (RX -> TX, TX -> RX etc.) :-) CTS- and BUSY- aren't actually brought out to the comms port on the equipment at all; CTS- is currently jumpered to ground internally, and BUSY- is left floating and brought to a test point on the PCB. RXD- is also currently jumpered to ground, which suggests that I can indeed connect TX on the RS232 terminal to RXD+ on the equipment and expect that side of things to work - I'm just not sure what I need to do with the TXD+/TXD- signal pair (which one actually connects to RX on the terminal end) (the actual comms chip is a 6551A, then the receiver for RXD and CTS is a 26LS32 and the driver for TXD and BSY is 26LS30) cheers Jules

Next Users: Cmments on Trillium's Speech Synthesis?

by dgy＠DakotaCom.Net

Hi, Has anyone running NeXTSTEP any experience with the Trillium speech product? This is the basis for GNUspeech. I am curious as to the quality of the speech produced and if it is worth pursuing (and if I should hunt for a NeXT cube or just follow the port onto different hardware) In addition to the auditory quality, I am interested in just how much of a CPU-hog it is (was). I'd be interested in any realistic (i.e. un-tuned) sound samples. Thanks! --don

A note on using RUNENT on some CP/Ms...

by wh.sudbrink＠verizon.net

Some users have reported problems that have been traced to the following cause: 1) Some of the ".ent" file programs depend on the Solos/Cutter routines to perform keyboard input. 2) Some CP/M implementations being run on Sols either configure the hardware in a way that is incompatible with Solos/Cutter or use the Solos/Cutter 1K RAM area in such a way that the keyboard routines can not function correctly. Observed behavior is that the program seems to function correctly up to the point where some keyboard input is required. Workaround: RUNENT places no restrictions on the start address specified on its command line. Use this to transfer control back to the Solos/Cutter initialization code (usually C000H). This will result in the screen being cleared and a Solos prompt '>' presented, once the ".ent" file is loaded. Then, at the Solos prompt, use the execute command "EX <address>" to run the loaded program. Example: A>RUNENT CUBIC.ENT :C000 <program load output here...> 0700: 07 EB 22 10 07 7D 93 6F 7C 9A B5 32 12 07 E1 C9 0710: 56 E4/ <screen clears, Solos prompt appears> >EX 0 <cubic runs normally> It is also possible that some systems may disable the Solos ROM as CP/M boots. Enabling/disabling the Solos ROM is a custom hardware modification that can be accomplished in a number of ways, so you will need some understanding of your system and of assembly level programming. You will need to write a small program at some unoccupied address range that reenables the ROM and then jumps to the ROM init address. This program will need to be converted into an ".ent" file and loaded along with the desired application (RUNENT can load two ".ent" files) and jumped to using the start address command line parameter.

OT: Hex to BCD conversion for programs

by rcini＠optonline.net

All: I'm working on a real-time-clock emulation for the Altair32 and I need a push on something. Most RTC boards return a BCD value to the caller. When you call GetLocalTime in Windows, it returns an integer value. So, I have to somehow convert an integer to its BCD representation. I thought about using sprintf on the integer and then returning str[0] or str[1] depending on if I need the tens place or units place. However, this seems to me to be an inelegant way of doing it. Does anyone have any ready-made C code to do this that I can use? Thanks a lot!

ISO: Compaq Portable 3 "docking station" (?)

by dgy＠DakotaCom.Net

I'd like to find a docking station/expansion chassis for my Portable 3. It's my understanding that this will hold *two* (full size?) ISA cards. I'm hoping that this will be a good, *compact* home for my Opus PM (I'd hate to have to set up a regular PC for this -- the Portable 3 has the advantage of the built in display, etc.). Alternatively, can anyone suggest something that will hold two full size ISA cards in a similarly small footprint? Ideally, with a COLOR display instead of the Portable 3's orange plasma -- though I can live with the monochrome as the GNX code is early SysV without much frilly stuff (I think I have a beta version of X Windows 10 that might run on that hardware, though...) Thanks! --don

Can anyone program archaic PROMs?

by Chris＠ChrisPappas.com

Hi, I'm sort of stuck. The place I used to use for programming went out of business and I need to have four different programs put onto eight TTL 2K (256x8) 20 pin PROMs, two units of each program. The PROMs that will work for the application are: Definitely will work: NAT 74S471 SIG 82S135 Most likely will work, but I haven't tried these: Fujitsu 7118 MMI 6309 TI 28L22 Can anyone possibly help me out on short notice? What would this run cost? I've just subscribed to this list, so I'm not yet receiving posts, but I can be emailed at Chris at ChrisPappas.com. Thank you, Chris

Root password on solaris 5.7?

by compoobah＠valleyimplants.com

>I've been putting off picking up a couple from someone as the boat-anchor >alarm bells were ringing :-) Maybe it is worth my while to go get them even if >they only realistically sell for a fraction of that price. I suppose Sun fans >like to use them for their intended purpose (for which they'll do a capable >job) - and unlike the desktop workstations they just don't turn up that often. I wouldn't get more than one, but one could be a good addition to your museum. Sun4d was Sun's first large-scale SMP architecture (possibly the comparison to a SPARCstation came from the fact that in a 4d the XDbus was bridged to MBus-based processor boards that had SuperSPARC modules (2x per board) on them (and SBus slots). Oftentimes the SPARCservers were paired with a SPARCstorage array which used a nonstandard (prestandard) fiber link up and mix of hardware and software control/striping. This combined with the fact that they are very picky about cooling (30 drives fit in one chassis) was why I didn't get one when I had the chance. Support for Sun4d stopped with Solaris 8. They won't run SunOS 4. I think that you can drop in a SBus framebuffer and run it headed. Wouldn't spend $300 on one, but I'd consider one for free as long as it wasn't too far away. I don't know about the boat anchor, but they'd make a nice sturdy step or stool if nothing else.

HD formatting utils for DOS

by teoz＠neo.rr.com

I was wondering if there were any drivers or utils available that would allow a DOS or Win3.1 machine to have drive partitions over 2GB? I know old IDE controller had hardware limitations to the drive size they can read (BIOS issues also) but would there be a problem with raiding SCSI drives on say an old Adaptec card to give you 20GB of space that DOS could read and write to (non booting)? I am not worried about DOS being modified so that the individual file size can be extended, just the available partition size so I don't have a dozen 2GB partitions. There are drivers made for Mac systems that would allow system 7.x to use volumes up to a couple TB when Mac OS 7.x could not have greater then 2GB partitions so I figured there might be something like that for the DOS machines.

Solbourne 3000 SPARC clone luggable...

by julesrichardsonuk＠yahoo.co.uk

Just had offer of one. Anyone happen to have a picture so I know what I'm dealing with visually? Google turns up almost nothing, and no images. I'm suspecting that it's not of sufficient interest to justify the space it'd take up (we have enough real SPARC hardware as it is, plus a couple of misfits like an Axil clone and a Tadpole notebook) cheers J.

old Hughes video projector

This used small CRT's coupled to a liquid crystal light valve. The ILA was a sandwich of materials that included a photosensor and the liquid crystal material. The CRT wrote it's image onto the photosensor which converted the light into a varying voltage. This voltage was transferred to the liquid crystal material which could now reflect light from the Xenon source. This is not a pixel based system, the liquid crystal material was a continuos sheet so would be able to image the full resolution of the CRT. They can have an almost film like image because there is no pixel structure. I believe the CRT's were infrared and so you could not see an image on the CRT face directly. Bob

Root password on solaris 5.7?

by compoobah＠valleyimplants.com

> I think maybe one of the current >sparc versions >of solaris may drop support of the Ultra 2, so solaris 9 might be a >better bet. Solaris 10 drops Sun4m support (8? (maybe 9) dropped 4c and 4d support) Solaris 9 is (comparing apples to oranges, x86 to SPARC) noticably faster than 10 (10 on x86-633, 9 on U1 200E). I think that Sun only makes available the current release of Solaris :-(((( not very much use to the classic community (be nice if they had older SPARCcompilers, too) but I guess (a) they want to show off the latest and greatest technology and (b) it doesn't hurt if it stimulates hardware sales. xBSD is rumored to mount Solaris filesystems R/W, Linux is still experimental (I think- haven't poked around in there too much, just select "y" and buld from there.) although it is stable. Any Solaris 2.x or 7+ CD should mount enought to be able to read the disk. The Ultra2 is a nice machine- dual-processor capable etc. You can drop in a UPA framebuffer to get graphics easily (Creator class graphics are quite cheap and 24-bit).

Could this be a battery >problem? (the battery was completely dead and I have no handy >replacement, so the battery compartment is empty) >Do I need to have a keyboard and mouse plugged in to get a response? The Beige G3 (if you're looking at a Blue & White (Smurf) MB (the case was B&W, not the MB), then the following advice is inapplicable) motherboard can be used with either a standard ATX power supply or a special Apple power supply used in their Desktop version of the case (as opposed to Mini-Tower which used ATX). There is a jumper near the rear left corner of the motherboard with which to select the power supply being used. The jumper is probably set improperly, because this machine and the similar ones going back before 1996 (On-topic, <grin>) will power up even if there's no CPU on the motherboard. That is, pressing the power on button or the power button on the ADB keyboard will still power up the supply, even though the motherboard is brain dead. A Beige G3 could be missing any of three essential components if it was stripped. It needs a CPU, which comes on a 19X19 pin ZIF module. I doubt you overlooked that. It requires a voltage regulator. This voltage regulator delivers different voltages to the CPU module depending on the setting of sense pins in the 19X19 grid. This is less obvious, but I bet you have that. If not, it mounts in the ~2" vertical slot to the left of the ZIF socket. Finally, the ROM (firmware) in the Beige G3 is on a DIMM module. There were three common revisions of the ROM. Revision A lacks support for slave devices on the EIDE channels. So only one drive per EIDE channel. Revision B and C are essentially indistinguishable except that revision C doesn't play nice with some Skyline ethernet devices. Without a ROM module you won't be able to boot either, though it should power up. The two 32 bit wide ROM chips (weird ROM chips, noone makes 32 bit wide nonvolatile storage any more) on the Revision A have part numbers ending in 40x. IIRC they're something like 343S040x or some such, but I'm really hazy about the fifth character. The rev. C ROM chips' part numbers end in 49x. I'm not sure about the Rev. B; presumably something between 40x and 49x. :-) The battery, keyboard and mouse can all be dispensed with if all you wish to do is boot the machine. The battery is a 1/2AA available at Frys for about $6 or at Radio Shack for closer to $12. Jeff Walther

NCR Minis: Re: PeeCee clones; was:PCW's 25 worst tech products

by ken＠seefried.com

I spent some time with the NCR minis at AT&T and a soon to bankrupt major airline. The premier box was the 3600, which was probably the box that the original poster described as "2 refrigerators", or some such...it was about that big or bigger. As I recall, it had up to 32 i486 processors (I vaugly recall a Pentium upgrade, and maybe a PPro one) and used some Teradata interconnect IP. They were touted as "data warehouse" boxes, and were usually used for some big DB app. Million dollar boxes. Ran pretty bog standard SVR4. I never saw a place to plug a keyboard and mouse into one of these... Then there were the 3550, 3500 and 3450 (at least...I think there were more). Proprietary Pentium multiprocessor, Microchannel minis...well constructed and fast for the time. Kinda sorta like Sequents. They ran SVR4 or SVR3.2, and I've seen at least one of them run NT 3.1. Someone even thought about porting Linux to the thing: http://www.anime.net/~goemon/linux-3550/. I shall not hold my breath. All of this stuff was superceeded by the Worldmark line, which was pretty much standard multiproc Intel stuff with an NCR badge.

Disk idea for my 11/34

by ISC277＠CLCILLINOIS.EDU

Hi all, I got a UNIBUS ESDI controller and I'm currently shopping for a disk drive for it. What I was thinking of doing is mounting a bracket inside the BA11-K and powering the disk drive from the BA11-K power supply, just using a molex connector to one of the unused harness connectors on the power distribution board that supplies the correct voltages. Would doing this pose any sort of problem? i.e. violating amperage limits etc? It would probably be something like a Maxtor XT-4170.

Request for tape reading DC100a

I have a friend who has a DC100a tape with no way to read it. Just wondering if anyone here can and get data onto a pc. I do have a Colorado Jumbo 250 that I have used DC 2120 QIC-80 tapes with. But don't know if that would read DC100a tapes. Keven Miller kevenm at reeltapetransfer.com Orem UT 84097.

OT-ish - old Hughes video projector

by gordon＠gjcp.net

I've just got hold of an old (probably late-80s) Hughes 800 projector. It's a couple of feet long and very very heavy. Inside is a big xenon lamp, a CRT of some kind, and some optics. It appears to work by shining the lamp (through mirrors) onto the face of the CRT. The big problem is, it doesn't appear to produce any video. I can hear the CRT scan coils going. The scan pitch changes when I remove the video source. In fact, it does appear to do all the things I'd expect when I press buttons, but no picture comes out :-/ There is (getting vaguely on-topic) an RS-232 port and it appears to use a TMS9900 CPU inside. Anybody got any idea how it even works? Even better, has anyone got an idea how to make it work *properly*? Gordon.

EU

Tony Duell answered: > However, the operation of a scanner is not too complex to reverse > engineer. Rather you than me. The only scanner I looked inside had several unindentifyable ICs... > I guess that we still can't get you to accept one, even for free, without > open hardware source. Surely you all know me by now. I am not going to depend on something that I can't repair. Tony --------------------------------------- Billy: I'm still glassy eyed about this statement. So I thought I would tell you a little about some work I did in the past. In OKCity, I was responsible for all the customer support documentation on the MPI floppies, cartridge and fixed disk drives. In the early 80's I had to do a study and recommend ways to reduce costs - publications had become a huge cost empire within Engineering. And whole product families were being delayed while the elaborate manuals were written and prepared. Customers were complaining about the enormous cost of maintenance. So I sample polled the largest customers for our drives. It was a couple of hundred out of 2500+. At that time, the only ones who replied that they needed schematics were a couple of repair services. We asked on theory of operation, app notes, etc. Same thing. None of the customers paying the bills used any of the elaborate documentation except for the interface specs. The conclusion reached was that schematics were not required and they were dropped. If any customer complained, I was to supply him engineering drawings as schematics. No customer ever complained. (Note the word customer - the ones who spent the money. A few third party types weren't happy, but they were a real thorn in our side then.) Theory of Ops was dropped. So were wire lists. Parts lists stayed - always like to sell parts at slight markups. (Sarcasm implied.) At that time two other trends were starting. First, most products no longer needed card cages. ICs allowed all the logic of a drive to be on one PCB. And we certainly did not want end users mucking up those boards by trying to repair them. (Also, many of the circuits were tuned in PCB fab; swapping out an IC wouldn't always fix the problem. It had to be tuned to be optimum.) Second, the first ASICs were used; I believe the first ones for us were on the 8" products. Physical size and board space were suddenly critical. The shrink to the 5.25" Wren series was really tough for engineers who were used to designing individual boards bigger than the entire Wren. So - the MPI official policy was to no longer provide documentation. The customer did not demand it, wasn't willing to pay for it. With ASICs and single board drives, we didn't want them to repair the units. The customers were pleased with the change - they were able to reduce their maintenance staffs, their spare parts costs and their cost of ownership. I'm cutting out a long section out here about the reliability of replaceable components vs limiting connections, adjustments, power etc. It is the same argument used on anything electronic. The point to all this is that a series of conscious deliberate decisions were made to prevent what Tony wants to do: repair to a component level. Repair cost money, was unreliable and required massive support. The world would only pay for cheaper product. The ASPs for disk drives moved from $3000+ to sub $50 in 15 years while the capacity went from 16 MB for Wren I to a terabyte today. A repairable drive was a luxury that nobody would pay for. And as time has proved, was unnecessary. Since that time, more than 20 years, Tony Duell is the only person I've met who insists on repairing his personal work system to the component level. Everyone else, wants it to be cheap and reliable. And that includes the most fanatical military buyer. What's next? My last three employers all had long range programs to get the entire drive electronics and interface down to one piece of silicon. And they want to eliminate the connectors as much as possible. Hard drives will be soldered to PCBs before the end of the decade. Optical drives are a little harder because of the form factor. They will achieve one piece of silicon, but it will probably be mounted on the OPU and have a 4 wire serial interface. As everything moves to SOC (System On A Chip) designers become firmware engineers. And already, there are plans to make firmware easier and more modular. The goal here is to have the system design itself from a few high level instructions. I understand Tony's feelings - I've encountered similar viewpoints many times in other fields. But it makes me sad, because he can't share a lot of the fun with us. We can't send him scanned manuals and he can't send us some of the work he has done. And what about photos from our conventions, videos of the speakers, software that is on CDs not floppies? The exchange of knowledge that bonds the rest of us is lost with Tony. And he has lots of knowledge that we would enjoy seeing. Billy

MM5203Q (256x8) EPROM pinout?

by julesrichardsonuk＠yahoo.co.uk

Anyone happen to have this? It's what the IMP16 board uses, and I'd like to see if I can build an adapter for my programmer to read the data out of the ROMs before I get rid of the boards... (I suspect it's a 3-rail device, but the address and data lines are TTL, so hopefully I can make them appear as 2Kx8 devices* to my programmer) (* The smallest ROM my programmer knows about is a 2716 single-rail device) ta Jules

M7800 setup - need help

by ISC277＠CLCILLINOIS.EDU

Well, I got my 11/34 working, it comes up to a console and it all works great. I have a second M7800 card but I'm not real sure how to configure the address and interrupt vectors on the card. I did figure out that: A. I have the 4.608 mhz crystal, allowing me to do 9600 baud with it. B. I removed the two caps that were in place according to the manual "FOR 110 and 150 BAUD ONLY" C. How to set the 9600 baud rate for both send and receive D. How to set 1 stop bit, no parity, and 8 data bits. So I'm good to go with it except for two problems: 1. When it is put in to replace the DL11-W (which would be much easier to reconfigure later, what with its switches), it causes the machine to halt at 173524 on powerup (this also happened before I removed the two caps, so it's not that). I just want to set this thing up as the serial console, for 9600, N/8/1. Can someone help me out? Thanks Julian

Disk idea for my 11/34

by ISC277＠CLCILLINOIS.EDU

Hi all, I got a UNIBUS ESDI controller and I'm currently shopping for a disk drive for it. What I was thinking of doing is mounting a bracket inside the BA11-K and powering the disk drive from the BA11-K power supply, just using a molex connector to one of the unused harness connectors on the power distribution board that supplies the correct voltages. Would doing this pose any sort of problem? i.e. violating amperage limits etc? It would probably be something like a Maxtor XT-4170.

parts

by rtellason＠verizon.net

I did some minor updates to my parts pages (a few new items), to be found at: http://www.classiccmp.org/rtellason/parts-index.html and I hope that some find that info useful. Also, I've acquired several thousand additional NOS parts of all sorts, so I finally got into it and inventoried the whole mess, and a list of what I have a *lot* of (or in some cases don't think it's likely I'll ever use) and put that up on another page, see: http://mysite.verizon.net/rtellason/w4s.html Maybe some of those bits will be helpful to you guys wanting to keep some of that older stuff running...? -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

DTC-01 Drawings

by dgy＠DakotaCom.Net

Hi, My DEC DTC-01 seems to have an intermittent when the clamshell is closed. I suspect the (ahem) "ribbon cable" that brings power to the main PCB is just to d*mn heavy-duty and is flexing the board or one of the connectors. Too many conductors to check individually (since you cant access either end of the cable with the clamshell closed and would have to attach pigtails to all of them). Perhaps someone has a drawing set and could tell me what's *on* each conductor (so I can make educated guesses as to which to concentrate on)? But, somehow, I don't think DEC was in the publication mindset when it was released. :-( Thanks! --don

On this (semi) subject, I vividly remember for a while seeing a "solid state VTVM" that had the extremely high input impedance of a VTVM/DMM + the good low-range response with an analog output. Now, all I see are the "classic" passive VOMs. What happened to the VTVMS? were they "not necessary"? I'd possibly be worried about meter loading messing up some computer circuits with a passive VOM (10-20k vs 10M meter resistance). Scott

First bug fix on ENT file utility

A reference to the file error message, which is in the relocated block, was not in the fixup table.

Selling things with lots of gold in them... (natsemi)

by julesrichardsonuk＠yahoo.co.uk

I've got a Natsemi IMP-16C CPU + memory board [1] here (plus cardframe, circa 1974) that's packed with gold/ceramic chips - I'm considering off-loading it though as it's not relevant to the sorts of things I'm interested in. [2] Question is though, surely if I put it on ebay there's a fair chance that a gold scrapper will get it rather than a computer enthusiast? What do others normally do in such situations (or do they sell elsewhere?) [1] It's in remarkably good condition and likely stands a good chance of working, if someone wanted a fun project (manuals are on bitsavers). Some corrosion to the tops of some chips, but seemingly none to the legs, PCB tracks, IC sockets, other components etc. It's evidently been stored well throughout its life! [2] I *badly* need to thin the collection out a bit and free up some space! cheers, Jules

Macintosh question (G3, 7 years old, so OT)

Original Message: ----------------- From: Ethan Dicks ethan.dicks at gmail.com Date: Wed, 28 Jun 2006 08:26:41 +0000 To: cctalk at classiccmp.org Subject: Macintosh question (G3, 7 years old, so OT) A quick question about the Mac G3, if you'll forgive it being not yet on-topic. Feel free to reply off-list to avoid rampant topic drift... Does anyone here know about the internals of the G3 line? I have a motherboard in front of me that I'm attempting to see if it will work. It came from a machine that had already been stripped, so there's no guarantee the hardware is functional. With the Apple Reset/NMI board installed, and RAM, and the Apple-enhanced ATI Rage 128 video card, I've attempted to see if it works by plugging in a PC ATX power supply and pressing the "power on" button on the motherboard and on the Reset/NMI board. I get a brief green flash from several LEDs, but the PSU doesn't kick on the fan, and the machine does not appear to be starting. Do I need an Apple ATX supply to test this? Could this be a battery problem? (the battery was completely dead and I have no handy replacement, so the battery compartment is empty) Do I need to have a keyboard and mouse plugged in to get a response? Thanks for any tips. -ethan Hi Ethan, I had a same problam with a G3 MT then found out it requires a Mac keyboard, that has the power button on it.

OT: Treo 650 for sale

by evan＠snarc.net

Sorry about this gross OT-ness, but maybe someone here is interested. I ordered the new Treo 700p today, so my 650 is for sale. It's currently on the Sprint network. There is one very, very, very tiny scratch on the screen which doesn't interfere with its usage at all. The phone speaker is broken (callers can hear you, you can't hear them) which I'm told by Sprint will cost less than $50 to fix. I'm asking for $100 as-is (charger and original manual included) and whatever the shipping cost is from U.S. postal code 07081. Please reply off-list to avoid further ticking off the purists. :) - Evan evan at snarc.net

Looking for a paper tape reader/writer

---ard at p850ug1.demon.co.uk (Tony Duell) says: > For the punch, I'd recommend a Facit 4070. They're relatively common I > think, easy to maintain, and fairly simple. The basic interface is an 8 > bit parallel one which can be linked to a PC with a little logic, there > was also an internal RS232/current loop card [1] and I believe I read > about an IEEE-488 card, but I've never seen one. I got one of the Facit punches off of Ebay. It works quite well. I built up an interface "adapter" that fits in a wire jumper box that has a couple of DB-25's (make & female). The circuit needed a single 7400 NAND gate, and a couple of zener diodes, but now my printer port drives the punch with NO software modifications. The interface wasn't that complicated, and I had to mush the parts together inside the adapter box, but it is just fine. I connected it up to my Linux box and 'cat /dev/lp' does the trick. Be aware: The Facit 4070 comes in two versions the 'DTL' version and the 'TTL' version. The signal levels are a bit different. The TTL version is the later one, and has easier level signals. Mine was the DTL one and needs some clamping zener diodes to make it all work. If you do get one with a serial option, note that it will probably cost a bit more (I've seen $100). Without is much cheaper. The schematics are on bitsavers. You might want to print them out on large (11x17 inch) paper they look nicer that way. As for the reader, that is another story. I got some off of eBay as well, but I have yet to get them all interfaced up.

bitsavers crawling?

by julesrichardsonuk＠yahoo.co.uk

anyone else having trouble accessing bitsavers in the last couple of days? transfers seem to be prone to massive slowdowns ( < 2KB/s ) from here (but other sites are fine). (I don't have Al's address handy or I'd ask direct if he's got some monster update going on or something) thanks J.

M7800 setup - need help

by ISC277＠CLCILLINOIS.EDU

Well, I got my 11/34 working, it comes up to a console and it all works great. I have a second M7800 card but I'm not real sure how to configure the address and interrupt vectors on the card. I did figure out that: A. I have the 4.608 mhz crystal, allowing me to do 9600 baud with it. B. I removed the two caps that were in place according to the manual "FOR 110 and 150 BAUD ONLY" C. How to set the 9600 baud rate for both send and receive D. How to set 1 stop bit, no parity, and 8 data bits. So I'm good to go with it except for two problems: 1. When it is put in to replace the DL11-W (which would be much easier to reconfigure later, what with its switches), it causes the machine to halt at 173524 on powerup (this also happened before I removed the two caps, so it's not that). I just want to set this thing up as the serial console, for 9600, N/8/1. Can someone help me out? Thanks Julian

I think DEC423 was very close to RS422, and there are few conversion problems there (reduced max cable length, I think).

SBC6120 (a build-it-yourself PDP-8 clone) Kits Available!

by bob＠jfcl.com

I posted a couple of weeks ago that Spare Time Gizmos was planning a "last buy" order for the SBC6120, a PDP-8 clone that you build yourself. To make a long story short, we did find enough customers to go forward with the last buy, and the chips and PC boards are here now. We'll start shipping them as soon as the bus connectors arrive, which should be before the end of the week. Most of the last buy kits have already been sold, but there are enough parts left over for about a dozen units. If you want one, then this is your chance! You can order one here: http://www.sparetimegizmos.com/Hardware/SBC6120-2.htm#Ordering If you've never heard of it before, the SBC6120 is a PDP-8 clone, including an optional front panel, that you build yourself http://www.sparetimegizmos.com/Hardware/SBC6120-2.htm http://www.sparetimegizmos.com/Hardware/SBC6120_Front_Panel.htm Thanks, Bob Armstrong

Uncrunching files with invalid characters

by Richard.Cini＠wachovia.com

All: I'm working on re-archiving the CPMUG ARKives into ZIP files and I've encountered a few files with filenames containing invalid characters in DOS (primarily the "/" character). I can extract with wildcards but the de-archiver (arce40g) doesn't seem to allow renaming on extraction, so I can't extract and rename at the same time. Any idea on how do accomplish this? Rich

(running over a short distance) A lot of RS422 equipment uses TTL level to create the +/- signal lines - hooking it directly to RS232 may blow up your tranceivers, not work, or both. Or, it may work - I think old Macs were tolerant enough to do that. The only "proper" way is to use a RS232 tranceiver chip (like MAX232) and 422 tranceiver chips (such as 75176(? - it's been a while)) or a creative arrangement of transistors and resistors. I can send you a quick schematic if you need. Joe.

Uncrunching files with invalid characters

by rigdonj＠cfl.rr.com

I've done something similar and it worked fine. Back in the EARLY PC days I was helping set up a company in Canada (Orlikon Aerospace) and we had to post data from a Martin Marietta IBM system to a MicroVax. The company in Canada was using a PC linked to the MicroVax to load the data which had been send from MMC on a pile of 5 1/4" floppy disks. The company in Canada could not get the data to transfer and I was there as a tech rep and knew something about PCs so the job was dumped in my lap. Among other problems, I found that their file transfer program crashed when it encountered certain characters in the data from MMC. I ended up using WordStar in a non-document mode to search for those characters and replace them with Zs. I choose Zs since they were very uncommon in the data and would be easy to find and correct once the data was in the MicroVAX. The beauty of WordStar (besides being one of the FEW PC programs available in that time and location) was that it will open ANY size or type file. At that time the ONLY PC available was an early IBM XT with a 10 Mb hard drive. I erased EVERYTHING off the harddrive even the OS and I was barely able to sqeeze all the data onto it. I even ran WordStar from a floppy disk. I took about 30 hours for WS to replace all of the invalid characters but when it finished we were finally able to load everything into the MicroVAX after 8 months of failed attempts.

wire wrap boards

preservation: linux and ST506/412 - SCSI bridge boards

by julesrichardsonuk＠yahoo.co.uk

Out of interest, has anyone else ever managed to persuade linux to talk to any of the Xebec/Omti/Emulex/Adaptec ST506-SCSI bridge boards? Most of the boards are SASI, or at best semi-SCSI, so Linux refuses to talk to them. Just wondered if anyone on here had hacked any of the kernel drivers so that they'll work. As I understand it, the main problem's that the kernel drivers issue a SCSI identify command at boot time - which of course doesn't exist on any of these boards, and from that point on the kernel refuses to acknowledge that there's even a board there. I *think* a SASI board should work with a SCSI HBA, providing there's nothing else on the SCSI bus (at least that's what the Omti manuals suggest). Sure would be useful for backup purpose, but last time I looked at the kernel SCSI code (for an adaptec driver in that case) it was pure spaghetti :-( cheers Jules

preservation: linux and ST506/412 - SCSI bridge boards

by compoobah＠valleyimplants.com

> But why anyone would want to set up something with an ST-412 interface on >the far end at this late date is beyond me. If you didn't have to reformat the drive (not sure how the bridgeboards worked in this respect), it would allow you to pull data off of a ST412-interface drive onto a modern one for backup. I have an IRIS here that the PM2 is nonfunctional, yet I would still like to see if I can salvage the O/S off the drive. The other thing I could think of is perhaps SunOS would have a Data Systems Design driver and I could drop the IRIS controller in a VTM (VME to Multibus) adaptor and archive it that way . . . but a bridgeboard would be nice if it worked. > 2) How to set up the board in software; I expect the kernel will get upset >if it can't query drive geometry at boot time - but it's going to do that as >part of driver set up, before any vendor-specific commands can be sent to the >board in order to set *it* up. try scsiadd - Debian supports it, anyway.

backing up PAL chips

by julesrichardsonuk＠yahoo.co.uk

what's the most sensible format for backing up PAL chips such that they can be recreated on a different system to that which they were backed up on? My standalone EPROM/PAL unit seems to understand the following data formats: ASCII binary motorola s rec intel std & 8086 elan fuse map jedec mos tech texas tags tex hex ... some of which are presumably EPROM-only formats (I don't have a manual for the programmer) is there some sort of common format/size for PALs too when reading (akin to always being able to read a 27128 EPROM as a 16KB device regardless of who actually manufactured it)? I'm concerned that this programmer might be too old to have data on some of the PAL chips that I want to archive - but if I'm only interested in archiving them (and so can set the type to something of the right 'geometry' from a different manufacturer) that's not necessarily that big a deal. Advice appreicated :) I'm used to working with EPROMs, but PALs are a total unknown to me! cheers Jules

HP 264x terminal status

by gginben＠cebridge.net

Attn: Jay West & Others I just happen to notice the thread that was written. So I would like to clear things up a bit. I never said that I wouldn't do the terminal deal. When you asked me about it I simply said "My number one priority is making sure that all the guys that purchased one received all of them ok. My customers are always first, and would hate to get rid of all of them, and then somebody didn't get theirs. So honestly at this point Jay I haven't forgot about you." As far as your quote about having someone pick them up is not correct either. This is the email that I received >from you "I've read this, and empathize. I'm not sure I follow though, if you still want the bulk purchase deal or not. Please let me know so I can let the other folks know. Jay West" Where all the other came from I am unsure. I am not meaning this email to be in any way demeaning or anything close. Just simply wanted to make sure that I could explain what happened. As far as as this quote from John A. " The other thing was that I was looking for positive word from anyone that the shipments were getting through and Gessman 'lost it' before Anyone was able to respond, deal cancelled. John A." I didn't lose it. , but thanks. You simply lied to me at first by telling me that you had sent a money order. Just to find out later the truth was that you wanted to wait and make sure that someone received one before you made a payment. I don't blame you for wanting to be like this. I just didn't care to do business with someone that wanted to pull wool over my eyes. I even canceled the non paying dispute to keep you from getting a strike from ebay since you finally did tell me the truth. Just so you could tell everyone here that I "lost it" Should anyone have any questions at all please don't hesitate to email me Thanks, Greg (Gessman Business Services)
