Getting stuff _back_ from standalone backup

by cmcmanis＠mcmanis.com

Argh, Ok, this is perhaps a dumb question, and I need to go find my VMS system managers manual, (no doubt it will be at the _bottom_ of my pile of VMS docs). When I have a tape that I created with SYS$UPDATE:STABACKIT.COM and I want to restore that tape on to a disk, what do I type to it? I tried this: BACKUP/IMAGE/VERIFY MIA2: DIA0: but it complained that it couldn't open [SYSEXE]. on DIA0 (which makes sense since DIA0 doesn't have anything on it yet!) --Chuck

uses for 386sx/NBI OASYS 8

by dasqua＠yahoo.com

I have a few 386sx boxes configured in various ways: - DOS/linux based test environment for developmental ISA cards - windows - print server for two printers serving around 10 computers of various kinds (win nt, 98, linux) - linux - data concentrator for a network of controllers (provides ethernet gateway for a large number of C64s used for controlling greenhouses) A large number of others perform other tasks, often in 1MB RAM with no real video or keyboard. most of them talk via ethernet or serial to ethernet (PPP). some are windows based, others DOS, others linux. As for booting win95 on 386sx it takes awhile, but 10mins is exaggerating. oddly, some tasks are the same speed as on pentium, but you can almost see it drawing the graphics. given I have crippled it with not even a 1MB card I'm not surprised. (256K I think). After patching the windows box it has now stayed online for approximately four years, with downtime for maintenance, upgrade of memory, and installation of printer drivers/redirectors. The patch is needed since the old version of 9x has a timer overflow which crashes it after a certain number of days of uptime. go figure. ..... Anyone have information on the NBI OASYS 8 system? It was a wordprocessing system made in the 80s (late 70s?). It all works fine, and has a 10MB harddisk (SCSI I think), system unit, and two terminals. My basic question is: how do I talk to the terminals? when they boot up they instantly contact the system unit. this is fine, except I want to use the terminals for something else... they are mostly motorola gear: 6809 cpu, sram, io, video etc. I think the networking used is ethernet... the terminals connect via a coax at least (but this is only a guess) I also have two daisy wheel printers. These have print server boxes on the back which put them on the network. the system uses basically 6809 CPUs in various flavours, although the harddisk has a relative of the 8086 onboard. any thoughts? Unlike the rest of my old computers this one is staying in the original number of pieces from the factory! Darrell _________________________________________________________ Do You Yahoo!?

These are like a meccano set, everything unbolts pretty well, but you will wind up with a mountain of screws and washers. They suffer from what we used to call in the domestic electronics servicing industry 'cousin effect' - the designer had a cousin who owned a screw factory. :^) Someone once mentioned that a friend was attempting to build up one of these minus the cabinet, ie just the cages and psu's, it would be a little tricky, but probably possible, and it would make it a lot more compact. LV and HV PSU's may fail occasionally, and the TK70's are painful at times, everything else in there is ultra reliable. > The two machines I will give away will have 2 CPUs each and 256 MB RAM.

That would be good, the SDI would probably be the easiest to find, though not necessarily the easiest to support, with the XMI-BI stuff in the middle. <SNIP> > Matthew Hudson offered to donate SDI disk drives and perhaps a DSSI > interface card. The SDI drives are heavy (64 kg, according to Geoff.) If they are RA8x's, yes, big, awkward, heavy suckers, I can barely carry one on my own. RA9x's are around 30kg, weighty but tolerable, quite reliable and 1/3 the power/noise of the RA8x's. The RA8x's are power hungry and unreliable (the spindle bearings tend to pack up - the platters are 1/2 metre across and are belt driven!) not to mention very noisy. I have several, but do not use them anymore. RA7x's are house brick size/weight, with usual 5v/12v power, but you need at least the SA70 and the right SDI cabling (The cabling is the same for any SDI drive.) Trickier than it sounds, since you can't connect the black SDI's leads directly to the SA70 RA9x, RA8x, you need the cable and socket affair that is on the rack cabinet. You should be able to find some without too much trouble, if the RA8x's are in cabinets, the same cable loom will work with the SA70 enclosures or RA9x drives. 81's are 480mb, 82's are 620mb. 90's are 1Gb 91's 1.2Gb. 70's are 250mb, 71's 750mb, 72's 1Gb, 73's 1.2Gb (I think). You would just about fit one Ra8x in the bottom of a 6k, maybe, 2 RA9x's fit comfortably, and an SA70 is virtually the same dimensions as a single RA9x drive, so in theory you could fit 8 x RA7x's in their SA70s' in the bottom of a 6K, but you would need 2 KDB50s to support them. > Brian, you're organizing the truck for shipment to Bloomington? I'd > be most grateful if that truck would also bring my machine home in > Indy. We may need about 3 to 4 more hands. Ideal number for manual handling of 6k's is about six, and if the truck bed isn't too high, you can stick a thin mattress under them, lay them on their side on it, and slide them off onto a hard surface, then wheel >from there, if the floor is smooth enough. A forklift is much easier though. ;^) Done it both ways. > If need be I'm willing to > accompany you to Bloomington to help with carrying the stuff you take. > Make sure you get a heavy cart and lots of strong and long straps.

The 318kg is bare machine weight, and does not include disks (which are not mounted internally in 6ks - my setup is nonstandard) or optional extras like the Battery backup pack, (do any of these have one??) which weighs about 40kg or so, (mostly the SLAC batteries). If you intend to do the 3phase-single phase conversion, you can save around 30kg by removing that bloody great autotransformer between the mains input box and the 300V supply. It's surplus to the conversion. Every little bit helps when you are moving something this heavy.

vaxstation 4000/vlb

by jim＠calico.litterbox.com

Anything I should know about my new vaxstation 4000/vlb that I picked up on ebay for 47 bucks plus shipping? My intent is to replace my somewhat dead 3100 with it. (I sort of got the replacement memory board installed *backwards * and things went downhill from there. It's probably not really dead, but 8 megs of RAM just isn't enough.) I intend to run the thing headless, btw. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- BeOS Powered! -----------------------------------------------------------------------

Just a dual J-K flip-flop made around Christmas 1977 (a 7476 is a standard 16-pin DIP TTL JK F/F, and date code 7751 would be week 51, 1977). -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

IBM 3380 drive pictures

by xds_sigma7＠hotmail.com

Hmm, maybe I should take pix of the assembled drive unit? They are no smaller than 1.26GB each, since the smallest 3380 model was a 2.52GB total unit.. I have no difficulty believing the age of the drives, they're fast as hell and store a huge amount of data, my 3380 is an AE4, which makes it a 5.04GB unit. Average seek time of 17ms or less, depending on the model, and data rate of at least 3MB/sec. Average latency of 8.3ms _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

Need help identifying HP part

by dan＠ekoan.com

Hello, At the Baltimore hamfest last weekend I picked up several 9825 HP-IB interface cables in a box. At the bottom of the box was a Hewlett-Packard IC labeled 1820-0076. It's a 16-pin DIP plastic package with the following stamps: 7476N 7751 SA 1820-0076 The chip looks to be in good shape and is in anti-static foam inside a plastic box. Any ideas what device and purpose this IC might be for? Another mystery device in the box was a 98028A "Resource Management Multiplexer" that has four DB-15 female connectors and what looks to be a 50-pin harmonica-style connector at the end of a short cable. Cheers, Dan PS At the 'fest I also picked up an HP 9915B (with option 002) along with a 98155A keyboard and three interface cables (two serial and one HP-IB) as well as an HP 82905B printer. I also bought three TI-99/4As and two expansion chassis for them (one new in box and the other populated with floppy disk drives and additional memory).
