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!)

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!

Typical Cluster setup. Pity you didn't get the HSC and other bits too.
I'd give you one, but it's a little far to ship it.

Which PSU is crook? The mains input box, the 300V supply or one of the
LV supplies?

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.

Nice.

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.

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.

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.

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.
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.

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).

Board has 3 notches. on back it says "DEC DMV11 Microprogram Control". It
also has the following numbers: M8053 on one of the top fingers. Also
CS*ABCDEFHJKLMNPRS also DDCMP ADDR BOOT enable. Can anyone tell me what this
is and what it does?

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

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).
