And it has IN and OUT for most signals, so you can do loopback and
daisy-chaining.

As Tony has pointed out, it's very easy to convert -- all the Astec and BSR
SMPSUs that were used have a link you can make for 110V operation.

It is interesting that 5150 is also the numerical code attached to the
process by which a person is involutarily committed to a mental ward.
The first personal computer I ever saw was an IBM, though the number
is not now known to me. However, it had a switch on the front which
allowed for either execution of a BASIC interpreter, or execution of an
APL interpreter. It was a little larger than an Osborne 1 but, its
structure
had a lot in common with the Osborne 1, or the Kaypro, etc.
That a person does not have knowledge of a source of a "BIG IRON"
machine, nor the ability to operate it has little to do with the definition
of personal computer.
In the early to mid 70's, I was an operator of 360 and 370 computers, and
believe me, it is perfectly possible for a single operator to keep such
machines in operation.

Just how many of the 600's were made/possibly are still in working order?
Just how rare are they, and how much would one be worth? I had people
trying to sell me non-working ones for $50 and over (I didn't buy them
because I have a working one).
Also on the topic of the 600, Does anyone have a modem cable and a printer
cable for one (or a BASIC chip)?
One last question...
Is there any way to run non-ROM programs on the 600?
ThAnX,

No idea but you sure don't run into them very often.

I have all of the above but I wouldn't be interested in parting with any of
it.

You could run programs from diskette. The machine has an 8086 chip in it I
believe and I think there was an assembler available for it but I've never
seen one.
I just pulled mine from storage over the weekend and discovered that I had
left the memory switch on several years ago when I put it up. Now it won't
boot even under AC. I guess I need to replace the backup battery - anyone
have any info on this?

For TV programmes, the flicker isn't really noticeable (though maybe it is if
you're used to 60Hz NTSC pictures). The higher PAL vertical resolution and no
3:2 pulldown is better suited to films than NTSC. No hue problems on PAL
either (no hue control at all).

I think VHF has long been out of use for TV in the UK. The old VHF transmitters
were turned off in 1979 (or thereabouts).
>UHF frequency bands: UHF frequency bands:
>channels 14-99? ?
>(not sure -- little-used, many

Don't know what channel numbers are used, though probably much the same as in
the USA -- I managed to get a picture using my old US portable TV the other
day (albeit in monochrome with no sound and slightly stretched picture).

SCART is super for things like computers and game consoles, since it allows RGB
input, something that apparently almost no US TVs do.

Use a step-up transformer (110 to 220-240V), frequency probably irrelevant,
though I'm no BBC expert. You should be able to find these in many places like
Tandy/Radio Shack.
You could hook the composite output up to a video monitor or TV. You might have
to adjust the vertical hold and vertical size to get a decent picture. And
this would be monochrome.
Connect the TTL RGB o/p to a suitable monitor for colour. As long as the
monitor has a v.hold control you should be able to get a stable picture.

SYSUAFALT from the docs (I think that's what it is) mostly works too, though
it might not
on some systems. The VMS faq mentions it, and suggests the other way as
being better.
YMMV.
I've used both at different times on VS 3100/4000 and Uvax II machines, and
on a 6000 (or two).

not sure about the 8533. there was a 9535 which of only a few were made which
had a 90 day warranty only, and then there is the 9533 a PS/2E. very cool and
although it's too new to discuss, WILL be a classic collectable. that's why
i'm keeping mine and hopefully can get the one back that i gave to my brother.
it was a 486slc and had one isa slot that usually had a pcmcia adaptor in it.

One of you thinks the 8530 (PS/2 model 30) was an 8088, the other thinks it
was an 80286. I claim you're both wrong. The model 30 was IBM's first
(and to my knowledge only) machine to be based on the 8086.
If I am wrong, and a 286 version did exist, no doubt flames will appear in
great numbers.
Philip.
The 30-286 did exist. I just sold one, and have one torn apart in my
basement. I *think* that they were the last ISA PS/2's. Not too sure
about that, though.
