Presumably if it has a UHF output it also has an internal modulator. Can't you
just tap off composite video from the input to that?
What chips _other than the 8048_ are in this device? Is the video side custom
or does it use one of the many Philips video chipsets? (Philips Prestel
terminals tend to be stuffed with their Teletext IC's, for example...)

I met someone who had worked on the Olivetti M20 many years ago and
could possibly still get a hold of some of these.
The M20 is a Z8001 based machine with bitmapped graphics and can run
PCOS (its own OS) or CP/M 8000
Is anyone else interested?

Keep in mind that Value <> importance/significance/etc. Value represents a
combination of many variables, including visibility, size, trendiness, etc.
There are plenty of relatively valueless items running around the world that
are incredibly significant, while a whole lot of insignificant things
command high prices on the open market.
If I wanted to invest in classic computers, it would be IMSAI's, Osbornes,
and Apple I's. But I want to collect them, so I've got an Epson, an NEC, a
m100, etc.

I think I've got a processor handbook for the -9 at home; it's
either that or the -15 (which was an up-rated successor to the -9).
I'll dig it out and post a few bits when I get home. (If I'm sober
enough. <insert grin as appropriate>) I seem to remember my first
impression was "bizarre machine"...

Despite have seen a few and being even an EX-digit I've never played with
the PDP-9. Is any there that can describe the archecture and instruction
set? Mostly curiosity here.

Yes thanks, I have four or five. I don't expect to use the thing until
I can find out how to get composite video or RGB out, since I don't
possess a television.
[For those of you not in the UK, here one requires a licence to operate
"Television Receiving Apparatus", which I think includes any TV with a
UHF tuner, but not a monitor. The licence fee is (without looking up
either the current fee or the exchange rate) about $120 a year, and I am
not prepared to pay this. So I don't have a TV - and seldom miss it.]
Philip.
Welp! I finally got one. Case got a little damaged in shipping,but it looks
like it will still work. Is there anyone out there that still uses the
8bit Atari's that can send me a copy of a Term program on an Atari 8bit
format disk so I can start downloading stuff to my 8bit atari's?

Dig the mixed metaphor!
Seriously though, there are two processes at work here. One is that
those who grew up with such machines have got the nostalgia bug. This
starts prices rising, which in turn attracts speculators. The latter
fuel the second process - articles get published about how fast the
market is growing, etc.
One hopes that in a few years time, they will become unfashionable once
again, and we will see a return to the situation when these machines
first became unfashionable - they crop up at car boot sales, etc., for
not much money.

Do keep us posted! There are plenty of us on this list who dream of
converting our private collections into musea when we retire - or
before! - who would welcome any info on the subject.

And however much we dislike the price spirals that occur, we must
remember that unless people know that collectors want these machines,
they'll put them in the dustbin.
That is one reason why, unlike Sam, I do not often haggle. If people
know that the Philips G7000 videopac computer that they priced at four
pounds at the car boot sale will get snapped up for that amount of
money, and tell people at work etc., others will think twice about
throwing out the PDP8 or whatever. If, however, they price it at L4 and
can't even get that for it, they will think that computers are not
collectible. (What is the G7000 anyway? Yes, I did buy it! It has an
8048 as the CPU, of all things!)
> > Are *you* prepared to pay $500US for an Osborne or a TI99-4a ???
No, but I'd rather pay $500 for an Osborne than see the last remaining
one disinegrate between the teeth of a rubbish crusher like that PDP9.

I had the same sort of reaction when I heard the news through
different channels. Needless to say I was less than pleased. However,
Mr. Donzelli believes there to be hope in this; he states that the
guy in question was willing to let him know about future systems
like that.

That's the proverbial $64,000 (65,536?) dollar question. I guess
we'll have to get to know the various scrap dealers (and especially
"recyclers") in our areas.

This is another hot-button issue with me, having seen what the
price of Altairs and the like is now. (No, the price is not
justifiable - other than the machines are very "trendy" right now
and speculators think they can make a killing on them.) However,
given the size of things like PDP-9s and mainframes, I doubt that
systems in that class are likely to fall victim to "speculative
collection". Some of the smaller machines in the PDP-8 class might,
but the PDP-8/I I just acquired filled half of the rear of my
minivan (the other half had an Interdata Model 4 in it) - a bit
too large for the average yuppie. You've got to be pretty sick to
collect things the size of refrigerators (yes, I know, I fit the bill).
Cheers.
