Atari help

by a2k＠one.net

Hello, I've been playing with my Atari 800 a bit, and the frustrating thing is I can't get the disk drive to work. When the drive is on and with a disk in it (is spins itself up alright) and turn on the computer, it doesn't try to read the disk (my last Atari, and 800XL I think.. did). In BASIC, any disk command (XIO, open, load, save, etc) give me an error that I looked up and means something to the effect of 'drive not present'. I've tried several utilities (myutil) on my PC to write the disks with mydos or ataridos, but I don't know if they're working as I can't write or read any disks. Any ideas, please?

Using 3/8" or maybe 1/2" plywood or OSB is good and 2x4s for uprights are adaquate but 1/2 or 1/3 pine straping is good for the rest and very cheap. If carefully done using screws appearance and disassembly should not be a problem. Allison

good excuse to run classic computers

by jim＠calico.litterbox.com

Here's a thought. If you've got classic computers you'd love to run but can't think of anything to DO with them, (and they speak unix) go to http://setiathome.ssi.berkeley.edu and make your computer's idle cycles part of the SETI search for extraterrestrial life. They download you a chunk of data from the Arecebo radio telescope and your computer spends its idle time running analysis on that chunk, then sends the results back. They keep track of what platforms people are using too. Wouldn't it be cool if the machine that finally found a real ET signal turned out to be a Vax 11/780 sitting in some collector's garage? They also have it as a screensaver for mac and windows, too. For reference, a "work unit" - about 300k of data all told - will take about 20 hours to process on my PII/300 machine assuming I let it run continuously. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

IBM available...

by jlwest＠tseinc.com

A company I do some work with just showed me their old system that they want someone to cart off. From what I saw (and I'm not familiar at all with somewhat recent IBM's), it appears to be a system/36. There is a floorstanding deskside size cpu enclosure, two or three smaller enclosures (same dimensions as cpu except about 8 inches tall), and a system console with a really huge base on it. IIRC, the system said IBM 5655 or something close to that on the front. They swear the system is in full working order. I have no interest in this period of IBM so.... It's in St. Louis, MO, USA if anyone is interested just let me know via email. Jay West

TK70 cartridges?

by cmcmanis＠freegate.com

Hi Everyone, I've got my TK70 up and running on my uVAX but haven't been able to find a lot of cartridges for it. Several TK50 carts, but no TK70. Imation stopped producing them! So if you know anyone who is decommissioning a large VAX installation that might have a few dozen of these let me know. I'm interested in keeping the media alive for a while at least! --Chuck

I prefer Gorilla racks. I've bought/installed some of the plastic units out there, and find two severe problems: 1) most have shelves that are NOT simple flat surfaces. Instead, they're often some kind of exposed honeycomb (or other grid). This has two drawbacks: (a) if you put small parts on the shelf, they can drop through; (b) you can't slide units that have legs or other protuberances. 2) the "heavy duty" plastic shelfs that I've used (Rubbermaid?) start to bow under the weight of some computers Stan

Breathing new life in laptop batteries

by fauradon＠mn.mediaone.net

Hi, Thanks for all the info. Apparently there are no reliable way to bring their youth back, I would like to have a reliable laptop with a battery that last more than 30 min. I found a Zenith z-star 433 VLp (500 Mb hd, 12 M RAM and color display and the Zenith J-Mouse!!!) that I'd like to use while away >from home. The batery I got seem to work for a while. Also it has four contacts does this means that it provide mutiple voltages or is there some kind of charge sense signal? I haven't brought the battery to the bench yet (no room on or near the bench:). Also the pack seems to be sealed pretty good, any elegant way to open it up and reclose it without too much damage? Thanks Francois PS: I actually got 3 of these laptops and built two from the set of parts and two of the batteries are totally shot: they get very hot when I try to charge them and of course no juice is coming out. I can practice on one of the dead ones. >> >This is the beast bet as cells fail with internal shorts and the cap will >> >dump enough energy to open them without cooking the cell. >> > >> Yes, but many times in my experience another short appears shortly.

Collecting PCs

by cmcmanis＠freegate.com

The general disdain with which PC collecting is met with on this list is understandable, however, I have been thinking there must be something here. I recall the folks who have collected PETs and C64s that are pretty common and "worthless" these days (I saw a new Vic20 in box at the Hamvention that they couldn't _give_ away.) So I've had some thoughts on what might be useful to "collect" when it came to the PC industry and this is what I've come up with: 1) All motherboard types - collecting one each of the "standard" sizes (AT, XT, Baby-AT, etc) 2) Collecting one each of all processor types. 3) Collecting one each of all media types. 4) Collecting all of the video standards. 5) "Famous brands", IBM, Compaq, etc. 6) "Famous peripherals", Bus mouse, XT keyboard, AT keyboard, etc This is something that anyone could start today since, like the computers of yore, this stuff is currently being tossed out. Comments? --Chuck

VAXStation/MicroVAX 2000 stuff

by donm＠cts.com

About a week ago I was exclaiming my good fortune in being able to have my VAXStation 2000 recognize a plain-vanilla Maxtor XT-2190 as an RD54 and proceed to format it. My concern being that if it did not recognize it, I did not know where to find the data required. I have since found it on www.vaxarchive.com. My intent in formating the 2190 was to install it in my MicroVAX 2000 and have a sort of 'matched set'. I am a bit sadder and wiser now that I have discovered that the MicroVAX is missing a rather large daughter board that resides beneath the motherboard in the VAXStation, and apparently carries the HDC and SCSI controller hardware. This seems to leave using the MicroVAX as a satellite unit to the VAXStation as the only alternative. Tried this, and MicroVAX tried to boot from ESA0 while cabled to the VAXStation, but no-joy. Is the problem that of not having things set up for cluster operation? If so, how do I do that? Keep it rather basic, please. I am pretty ignorant about all this. - don

I got my PDP-8E for free (PDP-8E cpu, box of spare cards, TU-56 tape drive, Paper tape reader, and a lowboy rack). Not only that, but the collector de-racked and loaded the system in his truck by himself, and offered to drive half way to meet me. I would suspect that this meets anyone's definition of free (ok, so I spent some gas money for me and him and bought him lunch). This system is one of the most treasured in my collection. I have spent many months painstakingly refurbishing the machine to factory new condition. So, I have to say that people *DO* value the things they get for free. Heck, the fact that I got it free makes me value the thing more than if I'd paid real cash for it, at the very least because if evokes fond memories of that day of pleasant historical computing conversation with the donor. And - that is not the only example. A truely kind soul on this list (to whom I am eternally gratefull) sent me an HP2108A cpu and PDP-8E 8K core board for simply shipping charges. There are many other examples. At the very least, since I have received this treatment from others there are times I have already sent out items for free, and there will likely be others in the future. That doesn't mean at ALL that I don't value them. Jay West

VAXStation/MicroVAX 2000 stuff

by allisonp＠world.std.com

<OK, the MicroVAX has the main board which is mounted solder side up. It <also has the extended memory card, a Network(?) card that connects via two Yes the LANCE chip (NI) is on a smaller paddle board. <40 conductor ribbon cables. What is missing is the large - almost main <board size - board that is situated component side up beneath the main <board, and connects to it via two 40 pin headers (that run parallel to <the 50-pin and 60-pin connectors for tape SCSI and hard and floppy drives <respectively) on the main board. Is that the Video Extension board? Yes. Without it you have mono video or you can run using a serial terminal via the printer port as console. The connector if pin 8 or 9 is grounded tells it to use serial port instead of the video console. I've hard jumpered mine so I can boot and run headless or use a more common cable if I want a serial terminal on the system. the 50 pin is the SCSI the 60 pins is HDC and floppy and the other larger board is the video extension. Without the video board they are the same beast. <Does the position of the Berg jumper about two inches from the rear of the <BNC connector affect the functioning of the storage devices? No. The storage devices are always available if the system probe finds them. It's possible to have a RX33 floppy(TEAC FD55GFV), MFM hard disk, A second RD5X MFM and TAPE(TK50) via a SCSI bridge. NOTE: the scsi is real SCSI hardware wise but the roms(and VMS drivers) do not implement compatable SCSI protocal so the only standard device is the oddball TK50. The SCSI oddity is from the mid 80s when SASI/SCSI was not a clear standard. For hard disks RD54 is the most desireable but v5.x can be trimmed to fit on a 71mb RD53 (DECwindows has to go,as I've got one here that way). Terminal support is via the DB9 printer port. If you can find one there is an adaptor P/N70-23766 that converts the video connector and the printer connector to three RS423 MMJ serial ports. I run all my VAXen to serial ports and a VT1200 DECterm, can't spare the space for the usual VR260/290/320 or larger tubes. Since DECnet does the equivelent telnet (and then some) one or two tubes are enough for support and talk to all of them. Hope this helps. I happen to have three of them, two running VMS and one with Ultrix4.2 on it. To that two MicrovaxIIs, 3 MV3100/M10Es, 1 MV3100/M76 sharing the eithernet with two MS PCs and a Linux PC box. Allison

Honeywell Bull + [OT] insert

This is true:I also know that Bull put the label "Honeywell/Bull" on many machines that were projected under Honeywell and still in the market when they step in (e.g. I've personally seen many CQ36 and CQ38 printers with both labels, according to theyr manufacturing period). >> The only system with the Honeywell brand that was called a BULL was >> actually an OEM'ed RS6000 that Honeywell put the BULL label on. >> Can someone confirm or deny? This is not true. After the DPS and before the RS6000 line, BULL presented a line of machines that should be a connecting ring between the DPS architecture and the UNIX. >Don't know about that but I have a box which I picked up from a >company I worked for a long time ago which was always called a >Honeywell Bull. It wasn't an RS6000 but used an M68020. The family name was DPX/2 and models no's went from 210 to 380 In the company where I work we are still running a DPX/2 380 under B.O.S.IX The machine was the last one that used the Motorola 68000 family. If I remember correctly, 2xx family was monoprocessors while 3xx where multi; DPX320 and DPX360 used 68020 and 68030. Ours (380) has one 68040 at 25 Mhz but could accept up to 4 CPU. ------------------------------------------------------------------------ Begin [OT] corner about price policy and machines sizing The funny (or sad) about that is that the expandibility offered by those machines are always not a good policy: After 3 years (1995) from the installation date, I decided to check the opportunity to upgrade the machine with another cpu. The official price was 21 million lira! (Abt 12 thousand USD) that was nearly the current price for a new system with a Pentium class processor: instead of adapting the price to the current market value price, they keep (or increase) the pricelist, probably to better convince them to change earlier the machine. I believe this policy is widely spread between constructors of propietary architectures machines. Now since the old DPX wouldn't see the lights of the new year in a sane condition, I'm quite indecided between the purchase of an entry level machine (you keep it 3-4 years then change without upgrades) or just a step further, with 2way processor capability. Do you have any personal experience on that?. End of [OT] corner ------------------------------------------------------------------------------ Coming back to DPX family...well before the IBM collaborations (and shares exchange) on the PowerPc architecture, Bull released a contemporary line machine based on a RISC processor that still used BOSIX. Again the name was DPX/2 (cannot remember models name). After this model Bull came out with Estrella and Escala PPC machines. Some machines where developed by Bull and manufactured by IBM for both labels, some were developed and made by Bull. Ciao Riccardo Romagnoli <chemif(a)mbox.queen.it> I-47100 Forl?

Apple Monitors ??

by owad＠caesarville.net

>One other question: What was the RGB port on the //c used for? Was this >for a high-resolution color monitor or what (other than the LCD panel)? Actually, I don't believe its an RGB port. According to the manual, the little icon above the port represents "Color TV". The port is used to connect an RF modulator. I recall reading that the only way to get RGB monitors to work with a IIc is via a composite-to-RGB adapter, which had not yet shipped by the time the book was published. While we're on the subject of video for the Apple IIc, does anybody know of any inexpensive composite LCDs that'll work the IIc? (Note that "inexpensive" rules out Apple's display.) Tom Owad

It's pretty easy. CLUSTER_CONFIG is a very friendly program, prompting you along the way. You'll need to know the Ethernet address of each satellite and establish some DECNET numbering scheme for your satellites. The hardest part is thinking up six-character node names for each node :-). Running a VMSCluster is very easy - it's only slightly more difficult to administrate a cluster of several hundred nodes than one node. Compare this with running a few hundred Linux or Windows boxes, a task that takes an army of administrators. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Any error messages on the consoles? You never say what OS you were trying to use, but I assume it's some version of VMS. You can login to the VAXstation as operator (or someone with equivelent bits) and run REPLY/ENABLE, that would, iirc, make the VAXstation log information to the console about clients requesting load images (and much more ofcourse).

SoCal TRW Swap 29th

by jpl15＠netcom.com

The monthly Southern California TRW Ham Radio and Electronics Swap Meet is being held this month (May) on Saturday the 29th, from 0730 hours to 1130 hours local time, at the TRW facility in El Segundo. Take the san Diego (405) freeway, exit Rosecrans, go West about 1 mile to Aviation (under the Metrolink bridge), turn left (south) on Aviation and proceed 1/2 mile south. The TRW facility will be on your right, and the Meet is held in the southernmost parking lots, bordering on Marine avenue to the south. Find a place to park and come join Marvin and myself, although I will certainly have gotten all the choice goodies first, (unless Marvin beats me to them). I am in spaces J21 and J23 and any classicmpers who will be in the area are cordially invited to join us. I have space available for anyone who might wish to unload some ju^H^H^H^H vintage items on the swapmeet attendees. There will be the usual after meet Brunch-n-Brag, at about 12:30 at a restaurant local to the swapmeet; all are invited. I am considering another collection Open House at my place, but that depends on feedback. E-mail me privately for further information/data/whatever. Cheers John

Regardless of the physical size, (maybe 13x15") if they are FT400 or FT300 models, then I may have useful information regarding their use. These models are FDC-only with a very easy programming interface. Back when I used a 1 MHz 6502 for much of the work, I used one of these and was probably the only one around with double-density capability as a result. The interface was dirt simple, yet could keep up with any processor of the time.

Amiga A1020 5.25" floppy drive (was Re: Atari modem)

It can be done, but I don't remember how.

How similar is plated-wire memory to core? Does it have the same wire-matrix organization, but is dunked into some magnetic gorp rather than having little torii strung on? Bill.
