My /37 has all five slots filled. The CPU, 2 HP-IB cards, memory, and the serial card with 6 ports. When I had the case open, I noticed a bus connector just behind the front panel. There is a cutout in the chassis above the connector where a ribbon cable could be passed to another backplane. I guess you could stack another chassis on top of this one.

A "WinChip 180" - kinda like a P-180 with extra stuff onboard to implement video on the CPU and use main memory as video memory (kinda like what the Amiga does, but not exactly). It's its own thing designed to reduce part count and manufacturing cost. > Tell me more about this, is the LCD part of it?? Yes. The idea is that you buy their box for cheap and give them $250+ per year in ISP fees, subsidizing the hardware. I'm going to go look at one at CC at lunch and see if you buy the unit over the counter and _then_ sign up when you bring the box home. I expect that they charge $199 at CC and you get $100 off your usage time. Even so, $200 for an integrated box that is reconfigurable isn't bad. I bought a proprietary flat-panel 486 with PCMCIA and one ISA slot for about that (16Mb RAM, 500Mb disk, no floppy but an external floppy connector). This is _much_ more powereful except for the lack of expandability and the lack of a built-in network jack. All I need right now is a source of used DE-620 pocket Ethernet adapters to charge on ahead. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

For the uninitiated, I think I must at this point issue a warning: THERE ARE TWO SERIAL PORTS ON THE COMMODORE 64. One is a (can't remember how many. 5+/-1)-pin DIN connector. This is Commodore's serial version of GPIB, and is where disk drives and things go. The other is the RS232. I can't remember whether that's a separate connector, or simply pins on the user port. I would guess the printer goes in the same port as the disk drive, if it is one of Commodore's own-badged Epson things. IIRC you daisy chain them - one cable 64 - Disk drive, next cable disk drive - printer, etc. Philip. ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Mixing high- and low-speed devices on the same HP-IB channel is not recommended. And adding I/O to the /37 is hard -- there are five slots, and between CPU, memory, ATP/M (serial I/O), and GIC (HP-IB) you're already using at least four. The fifth slot is often occupied by more memory or something else (e.g. an INP or LANIC). I think there's a way to add a second card cage to a /37 but I'm not sure I've ever seen that done. So if you really want a printer, you might want to think about a serial printer plugged into one of the ATP ports. I used to run a 2563A that way in the mid-1980s; 9600 bps did OK at keeping up with a 300 LPM printer that was used to print COBOL listings. > Anyway, I finally have a "Classic 3000" that doesn't double as a space > heater.

HP 3000/37

by steverob＠hotoffice.com

Hi gang, Went with Joe Rigdon last weekend and picked up a HP 3000/37 that he had spotted. The unit was mounted in a short cabinet with several 670H drives. It had been sitting partially covered in a scrap dealers yard in the Orlando area. Thankfully, it's not the rainy season so, it was still in pretty good shape. When I got it home and opened the computer up, it really wasn't that dirty inside. I just dusted the boards off, checked the connectors for corrosion, and reassembled it. The switch on the front panel was gummed-up and stuck in the off position. I broke it trying to work it loose and had to do some microsurgery to get it working again. I opened up each of the 670H drive cabinets, dusted them out, and reassembled. When plugged in, everyone of them gives a green light. A couple of them sounded a little funky during their first spin-up but, they all seem to be working now. Obviously, they had been sitting for a long time and were reluctant about going back to work. I can relate to that :-) All in all, I got (8) 670H, (6) 7963B, and a 7936 (I think that's correct) drive. The 7963B can support multiple drives in the same cabinet but, these only had one drive each. The 7936 is a big sucker. Similar to the 7937 "Eagle" drives. I've previously had trouble with Eagle drives so, I haven't even tried to power that one up, yet. These are 8" belt-driven monsters that are sensitive to shock and inactivity. The belts get all gooey and are a pain in the butt to clean. Last time I tackled one of these, I strained my back trying to put it back in the cabinet. That particular drive crashed within a week and really pissed me off. I mounted 3 of the 670H drives in the cabinet with the 3000, connected my tape drive, and powered everything up. After much dinking, I was finally able to install the OS from the MPE FOS tapes. I'm still a rooky at MPE but, after threee days of tinkering, I got it to work... YIPEE!!! Let me tell ya, over the last few days, I have learned a LOT about installing that OS. Still having trouble configuring the system with a line printer. Not sure if the problem is with the printer, the configuration, or me (naw couldn't be). When I connect my HPIB printer, the system has trouble finding other devices on that chain. That printer was working with my /42 but, it was on a port all by itsself. The /37 doesn't have as many I/O ports as the /42 so, my options are considerably more limited. Anyway, I finally have a "Classic 3000" that doesn't double as a space heater. Both me and my air-conditioner are happy. Many thanks to Joe for turning me on to this *great* find. See Ya, Steve Robertson <steverob(a)hotoffice.com>

IBM Channel attach (for DEC)

by cmcmanis＠mcmanis.com

Hello all, I picked up a nice DEC cabinet and nestled inside of it was a DEC Channel server which is apparently a MicroVAX II, 8MB of RAM, and a four or five board set that connects to an IBM "channel". Does anyone have any interest in the channel interface and the cab kit? (I've got designs on the BA23 and the rack which is what I wanted in the first place. --Chuck

Power supply for TS2068?

Well, okay, the KIM-1 doesn't. :-) What you need is a 15-24 VDC supply which can put out one amp, center negative. The 2068 is a very nice machine, but was abandoned when Timex ceased production. Very little software was produced for it, but with a Spectrum emulator cartridge you will have access to over 10,000 programs which are posted on the 'net. Disk drive interfaces are still available -- brand new -- as well as centronics i/fs and even EPROM burners, if you want to take it that far. I also have a speech synth and tape drives attached to mine. If you can get the machine for under $100, and it works, and you don't mind spending a little more time and $$ chasing down some extra hardware for it, you can put together a pretty cool 8 bit system with one of these. I use mine every day. If you need some more help let me know off list Glen Goodwin 0/0

HP computer stuff

by ip500＠roanoke.infi.net

A recent haul of HP computer stuff netted some HP3000 Series III racks, card cages and power supplies. Didn't I see someone on the list who is still supporting and/or using a 3000? There is also the cadaver of a HP3000 model 30 [actually looks complete but some one has pulled all the cards out]. If anyone is interested there are some pix posted at http://mh106.infi.net/~ip500/HPcomputers/ Not pictured but also available are a bunch of 2635B terminals, a couple of huge 2608 line printers, several of the 7920,20A or 25 disc drives and a wealth of tapes, manuals, etc... It's all [or mostly] for sale--I'm pretty reasonable--make that real reasonable--and price corelates inversely with weight! Pick up only in Roanoke, VA---only about 5 miles off of I-81. I'd be really interested in any trade proposals involving a HP2100---or earlier HP mini. Thanks, Craig

At the moment, I have no Xircom adapters (I'm casually looking for a bargain on a couple of PE-3s) and even if I had any, AFAIK, they only work under DOS and DOS derivatives, not any flavor of UNIX. There are pocket adapters that work, but I have never seen a working one for sale (there was this busted one at the hamfest...) As it turns out, one of the many pages on the iOpener that has sprung up claims that the modem interfaces to the motherboard with RS-232. I don't know if that means +/-12V or TTL, but it's a start. It appears to connect via a .1" spacing DIP header of 2x5 or perhaps 2x6 pins. Easy enough to squirt some data out the serial port and see what lights up with either an oscilloscope or even just a traffic light. > If linux supports USB there are all sorts of USB to whatever converters > including Eithernet, modems, printers... Depending on the USB chipset, yes.

I'm not worried about stuff not fitting at all - I have been playing with entire functional distributions that act as dedicated web cams or routers and the like that fit on a single 1.44Mb floppy.

TMS-7000 info needed

by kees.stravers＠iae.nl

I am looking for detailed information on the TMS-7000 microcontroller >from Texas Instruments. On the web information on this processor is very scarce. Among the many things I do is maintaining a web site for a Dutch Amateur Radio museum. This museum sometimes receives old rigs from the national PTT, so they can sell them to licenced radio amateurs. This way the PTT does not have to scrap them, and the homebrewers get quality rigs cheap, and the museum gets some well needed money. This time the rigs are somewhat modern, they are controlled by the TMS-7000. Rewriting the firmware of this rig should be enough to get it to work on amateur frequencies. The museum already has a pledge from someone willing to undertake this task, but he needs documentation on the processor. There is already documentation about the rig, but this only covers the radio part of the set, not the computer part. Does anyone have detailed info on the TMS-7000, like instruction set, appnotes, etc? This would be a great help. Thanks in advance.

Need RS6K help

by peter.pachla＠wintermute.org.uk

Hi, I've just gotten hold of an RS/6000 which appears to be a model 520 (7013?). Since the thing appears to be a server (POWERserver?), and thus has no display adapter, I need to get hold of at least one of the 10-pin to 25-pin serial port converter cables. Can anyone, preferably in the UK, help please? Also, does anyone know where I can track down a set of AIX 3.1.0 manuals - printed or electronic form? TTFN - Pete. -- Hardware & Software Engineer.

<One of the links I posted earlier mentions that there are two related Linu <distro's in the works. One will fit on a 500MB HD, the other will fit on <the SanDisk. Gee, I hate to tell you this but, I just installed RH5.2 on a 500mb drive no problem. So I put Openlinux2.3 on it to see the difference. It's very doable. I've got an old copy of FreeBSD 2.2.6 that would runs just fine on a st3660(500mb). Also I've been running NT4.0/sp4 worktstation on 486dx2/66 in 500mb (310mb free). NT for that box may be problematic due to drivers for video and all. Another OS that is a good candidate is MINIX2.02 as the whole can fits on 40mb with sources. I've run it on 10mb disk and 4mb ram. There is MinixVM also. I think there are plenty of possible OSs for that toy. Most all of them run some emulator we'd like to use. Allison

HP 2000 TSB question

by west＠tseinc.com

I finally finished testing out all the memory boards in my two HP2100's. I was getting misleading results for a long time due to my lack of understanding of the way the memory subsystem operates - it has to be tested in a very specific non-intuitive (and undocumented) way. Turns out I have four bad boards; three 8K SSA core stacks and one 16K ID board. These two systems ran HP2000 Access TSB, and had 32K each. My question is (before I spend time hunting down replacement boards) does anyone know what the memory requirements for the main and IOP cpu's in 2000Access is? If I can get by with less than 32K in each cpu I can forgo getting replacement boards for the time being and perhaps run with 24/16. Any ideas? Jay West

Can someone here telnet to my 11/35

by dylanb＠sympatico.ca

Thanks everyone for telnetting into the 11/35. It seems the 11/35 could handle the guests but not my PII-350 :-(. The terminal server is now repaired and it looks to be stable. .. though probably not as stable as the 11/35. I will be putting online many different PDP-11s/PDP-8s online throughout this week and the coming months. The 11/35 will have FORTRAN IV, MACRO and FOCAL added to it (with a lot more games) later on today. http://www.pdp8.com/telnet.htm Enjoy! PDP-8 and other rare mini computers http://www.pdp8.com

Alternately, it may be possible to remove the modem and add a MAX-232-based level converter and run a cable outside the case for "real" serial devices. I plan to inspect the innards and hang a scope off of whatever interconnects there are. Worst case, the UART is embedded in the modem and I'll have to be more creative by probably installing a 16550 on a daughter card in place of the modem.

I put down a $20 deposit on one and it is supposed to arrive in two weeks. The way the billing works is you pay $99 + tax for the unit and as soon as you connect it to a phone line and give it the go-ahead, the unit connects with the central office somewhere and you enter in credit card info and pick yout billing plan. If you never connect it to a phone line with the default QNX software, you never have to worry about signing up. I expect this policy to change when they see hundreds if not thousands of units sold with no service started on them. Until then, I've (almost) got mine.

What about the USB port? It seems like they are not using it in the iopener configuration but is it available to other OS's? If it is then eveything and more can be hooked up: scanner, CD Writer, floppy, mices, printers, joysticks etc... lokk pretty good for the bucks. I'm making a stop on the way home tonight.

Red Erasors

by edick＠idcomm.com

The eraser I always saw recommended was a "pink pearl" which was in commonly available supply at any office supply store. I never bought into the notion that the substance I was removing was "corrosion" for the simple reason that the backplane connectors and the PCB's were gold-plated. Since the eraser always left a clean gold plated edge connector, I quickly concluded it was dirt and not corrosion that was accumulating at the interface between PCB and backplane. I found much less of this occurring in clean environments where dust didn't accumulate in the equipment cabinets, so I did what I thought necessary to exclude dust from all the cabinetry, and, guess what! ... There was much less "corrosion" in the cleaner boxes than in the dirty ones. Dust doesn't cause corrosion, does it? It could cause abrasion, but I doubt that's at the root of these problems. My question would have to be, "How do you clean the backplane connectors?
