FTGH for pickup in So Cal v2: Macs, Atari ST, various hardware

by spectre＠floodgap.com

The PDP-11, VT100, Flyer/Video Toaster and some of the Macs have found homes, but there are still some items left and a couple more I added. These will be going to the recycler soon unless they are spoken for (all free to good homes). I may be adding some others, too. As before items are at various locations in Riverside-San Bernardino, CA. Please contact me OFFLIST to arrange PICKUP. POSSIBLY WORKING: Mega ST4 with Megafile 60 and SC1224 and SM125 monitors. These are a bit yellowed and the keyboard is thrashed. Also, the TOS is on a separate card with two leads that got loose and I don't know where they go (probably to +Vcc and a select pin). Thus, can't test the monitors or the hard disk, but the system does power on, and the hard disk does power up and makes happy hard disk noises. No idea what's on it. The SM125 puts on a power light and does appear to try to make a picture, though its previous owner separated it from its stand for some reason. The SC1224 sounds like the flyback is bad but may be serviceable. Includes ST mouse and hard disk cable. No manuals or software. If you want this unit, you need to take everything including the monitors. PARTIALLY WORKING: 500MHz iBook G3 laptop (snow, not colour) M6497 with tray loader optical drive and power supply. Does boot OS X, but needs a new LCD backlight (mini VGA port works and you can see the display in bright light) and battery is of course toast. Otherwise physically intact except that ex-bro-in-law put grotty stickers on it. PARTIALLY WORKING: Quad G5 2.5GHz x2x2, 8GB RAM, Nvidia 6600. Got whacked in shipping and one side of the case is damaged. No hard disk. Does power on but you will need to service the processors and the liquid cooling system. Aftermarket optical drive needs "help" when you eject it. Add your own USB keyboard and mouse. PARTIALLY WORKING: Sawtooth Power Mac G4 450MHz. No RAM, no video card, no hard disk. Used to be my file server but had issues with one of the PCI slots. Has optical drive and ZIP with matching Apple bezels. Does power on, but obviously without RAM or a video card (AGP) will not pass POST. Add your own USB keyboard and mouse. NOT WORKING: Single G5 1.8GHz, 2GB RAM, GeForce 5200. The previous owner seemed to have had a disagreement with the front panel connector and the front panel connector lost. I received it stripped to the chassis except for the processor and the logic board, but it does have the fans, video card, wireless (with T-antenna), power supply and panel cable. Because the front panel connector is busted I can't test it. You get to replace the front panel assembly and put it back together. This unit is air-cooled, but probably could benefit from reapplying thermal compound while you're at it. Has optical drive (disconnected), no hard disk, add your own USB keyboard and mouse. Various other items: Apple II Super Serial card with DB-25 670-0020-? (uses 6551 ACIA) and Apple IIe 80 column 64K memory expansion 607-0103-K. Can't test them but both look intact. Kurta Penmouse. Serial and PS/2 connectors. Seems to have a power supply jack (9V) but I don't have the power supply and I don't know if it needs it. Can't test it, no drivers, physically intact. Sun model 411 SCSI CD-ROM. Requires caddy. Won't mount discs, might need a recap. Samsung 17" SyncMaster CRT. Works fine, great shape, just too big to keep around anymore. UMAX Astra 2100U flatbed USB scanner with power supply. Powers on. Works with classic Mac OS but probably most systems. No driver disc. Pair of Telular SX5 GSM terminals. These were the server room's backup communication system. They work, but no GSM network to connect to anymore. Might be fun if you set one up. Real serial ports! Real GSM modem! Full kits with power supply. Visual UpTime Select T1 CSU/DSU. Has a Cisco V.35 cable connected and jacks for Ethernet, serial, DSX-1 and T1. Powers on, obviously goes right into Red Alarm since there's no network. You telco nerds will love it. Adaptec AHA-1542CF ISA SCSI card. I don't have a system to put this in. Looks fine, might work. No software or drivers. ATI PCI Rage XL card, VGA DE-15 port. Likely for PC, doesn't seem to have a Mac ROM. Good condition. No drivers. Diamond ATI Radeon HD 6450 PCIe card with DVI, VGA, HDMI. Has manual, no drivers. Good condition. Various complete external modem packages ranging from 14.4 to 33.6K. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Man fears Time, yet Time fears the Pyramids. -- Arab proverb ---------------

Multi-Micro-Channel bus systems, and thoughts on the Computer Society Digital Library.

by cz＠alembic.crystel.com

Read that Personal Systems magazine from 1992 that was recently posted and enjoyed the article on the PS/2 295 system. I never heard about that one, the biggest PS/2's I worked on were the 95 systems with 486 processors back at Covington. One thing that popped out: The 295 was a multi-processor-ish system with two MCA busses. Granted they were decoupled with each processor having its own MCA bus but it got me to thinking: Were there other systems of that time that could use two MicroChannel busses? I know of one: Back when I first started working at the IEEE Computer Society in 1993 they had a donated NCR 3550 system. Big box, mainframe sized with 4 486/50 CPUs in it and an MCA backplane. As I recall AT&T donated it to the CS but no one had a clue what to do with it. It ran NCR Unix which wasn't interesting but when we started putting together the first E-Commerce systems in 1994 I decided to use it with Windows NT. Oddly enough it could run NT 3.51 (and later NT 4 with a HAL) and we put it online with Netscape Commerce server. Ran great and just like that we were doing E-Commerce for SuperComputing/95 registrations. :-) Later we started building the Digital E-Library on it. We needed a system that could do a lot of SGML-HTML conversions quickly as well as render TEK Math to .gif in real time. So we upgraded the 3550 with 8 (later a total of 16) Pentium Pro CPUs and a second Microchannel bus. We split the disks up with 2 4 port SCSI adapters on each bus along with a network port each and balanced RAID1 and RAID5 disks across the channels on both busses. Worked surprisingly well and allowed us to load all of the CS periodicals on the system along with a big Lotus Notes server implementation to run the commerce software and store the E-Accounts (still in use today!). The E-commerce system allowed people to renew their memberships with credit cards, and of course add subscriptions both in paper and on-line with instant access once the credit card was charged. For mid-1990's timeframes this was pretty advanced stuff. Later when we composted PDFs we put those on there as well with the Article shopping cart so people could buy articles individually. Boy, people liked that a LOT. We did experiment with a digital credit system so people could buy points and use those to buy articles but I could never figure out how to make it tamper proof. Satoshi figured that one out a decade later, I wish I had thought of the checksum chain idea.... Oh well. But the big point: Running two MCA busses on a SMP based multiprocessor system was quite possible and do-able at scale, however did any other company make a dual MCA bus system? I always found it impressive that Windows supported even that stretch of a configuration (seeing 16 Pentium Pro CPUs running together as people hit the digital library en masse was *neat*) but I don't recall any other systems that did it. Thoughts?

Sourcing Capacitors for my H7140 PSU

by robert.jarratt＠ntlworld.com

I gave up trying to repair this PSU myself and I have got someone to do it professionally. It seems they have it working well but think that two capacitors should still be replaced. I think these are the two big "Coke Can" sized filter capacitors. The trouble is they seem to be unable to find any. The spec for them is 4500uf 200v DxH 76mm x 145mm Qty. 2. Anyone know where to find such monsters? In the UK ideally. I have looked on Farnell, Digikey and Mouser. It all seems to be special order, minimum quantity, long lead time etc. Thanks Rob

Hi, I own a Pro-Log M980 Prom Programmer and want to program a 2732 EProm. I have everything needed, but how can I get the data in? There is a serial interface, did anybody have some program for a standard PC to handle that daa transfer? Cabling istn't an issue, can do it. Thanks for helping. With best regards Gerhard

What's left of the Houston Museum stuff

by lee.gleason＠comcast.net

"Nice selection of dirty and yellowed computers in unknown condition." I just took a run out to the warehouse in question, figuring the owner would be there today cleaning up. The quote above sums up the state of things. There were some miscellaneous DEC terminals, a few MicroVAXes, and some other assorted DEC stuff - but it was all a trifle ...funky. That alone might not have been a sales stopper for me (all of my collection is not pristine), but the prices were a bit higher than I was prepared to pay for that condition and these circumstances. EG $125.00 for a VT220 w/o keyboard, and $90.00 for VT240 base units. I left empty handed. -- Lee K. Gleason N5ZMR Control-G Consultants lee.gleason at comcast.net

VA Vista

by bill.gunshannon＠hotmail.com

Only semi Classic as the subject has been around for a long time. I saw recently that the VA is moving to a new EHR System (not very successfully, so far). Does this mean that VA Vista and MUMPS are finally going to be scrapped? Anybody else hear anything? bill

core matt repair

by pspan＠amerytel.net

I worked at a company called DMA located in Amery Wisconsin during the 80's and 90's that did do core mat repair. Yes, the gal that did the work used a scope. She replaced cores and wires. Good luck finding someone to do that work now. If I remember the process, first the mat was removed from the driver assembly, then the varnish was removed. Then the mat was repaired and revarnished and then reassembled and final test before returned to the customer.
