Hmm, possibly some type of RX50 maintenance stuff.. e.g. head alignment etc.
floppies? Only a guess...

Hello,
I picked up a Teletype model 43 terminal at a hamfest this
weekend. It needs a new plastic bar that separates the
incoming from the outgoing paper as well as a new ribbon.
I'd also like to get a manual for it, although it appears to
be a pretty straightforward piece of machinery.
Any recommendations on places to go for spare parts?
Dan

I'm not so sure - I've recently started selling off a lot of my
duplicate Commodore equipment & books - for example, I've got SAMS 128
Assembly Language Guide (that I paid $29.95 for back in '87) currently
sitting at $73. Most of my other C= stuff has been going high as well -
I sold 23 VIC20 cartridges (no boxes or instructions) for $103 recently
& 18 C64 carts for $81.
On the other hand, the HP85 I sold a month ago went for $20, whereas
the one I sold 12 months ago went for over $200.
What I am noticing is that the 8 bit Commodore era stuff & Amigas are
holding (or increasing their prices) whereas the earlier stuff (that
most people on this list generally collect) is not pulling the prices.
There are a couple of Digital VAX machines on eBay Oz (vintage) that
are not moving at all.
Tastes change & I find that many of my generation (late 30's) are
wanting to relive their "childhood" so to speak - & that means
Commodores etc. Avg price on eBay Oz for a C64 is around $40 at the
moment. More depending on what's added in with it.
I've got some odd Intellivision II bits & pieces that I'm gonna try
next :-)
cheers,
Lance

To assist you in finding Sharp's logic, if any, I have a PC-1421
(handheld) which
dates from 1984. I also have a PC-5000 (not NIB like Sellam's, but
with more
goodies :), which is apparently a year older (but somewhat larger;
maybe they
went by size? :)

Subject: Sharp LT numbering
I acquired a little while back a Sharp PC-3000. I am very enamored of
it and
it's possibilities. Similar to the HP95 and will use the same memory
card
only with a more-manageable KB.
In researching it I found it came out in 91/92 and was a follow-up to
the Atari
Portfolio. The UK company (DIP) that designed the Portfolio and this
follow-
up model, offered it to Atari, which had it's own problems at that
time, who
declined it and then Sharp snapped it up.
Sellam gave info on a Sharp PC-5000 he was selling and Joe R. on a
PC-7000. These model #'s make no sense at all as I believe both of
these
came out before the 3K. Anyone with any insight ? Or is it just that
computer
makers use no logical system for model #'s

Hi Sellam,

Most of the TRS-80's here have started suffering from bit rot, but out
of the 40 or so C= machines I have, only 1 has a problem (fried CIA).

I have two Apple II's - one works, one doesn't - 50% failure rate!
<grin>
In fairness though, I've had more failures with C64 power supplies than
I care to remember - but the 64's themselves have been pretty tough.
cheers,

I came across a BYTE review of the Docutel/Olivetti M20
on page 188 of the June 1983 issue. Four pages of
text would not take long for me to scan and OCR.
The pictures, while pretty, are not detailed enough
for any technical information although the motherboard
photograph is good enough to let you identify it.
Let me know if anyone wants this done.

Well, this PDP-11/24 I picked up yesterday doesn't appear to want to boot.
All boards appear to be present (at least, going by the table under the lid)
and in good shape physically.
When I turn the keyswitch to 'LOCAL', the 'DC ON' light comes on and the
'RUN' light comes on for about 1/2 second. When I push the 'control' switch
to 'BOOT', the Run light comes on or about 1/2 second, then goes out.
Looking inside, there are three lights on the M7133 cpu board, labeled '0',
'1', and 'CLK'. The '0' and '1' lights are on continuously, the 'CLK' light
only comes on for the 1/2 second after power on, and while the 'control'
switch is held in 'BOOT'.
As usual, I have absolutely zero docs on this system, so any help would be
appreciated.

Yes, it should run just fine. I suspect you still have some
hardware issues...
