a couple of questions:
does anyone have a spare 16MHz 68k CPU (or a source in the UK who may sell
them - Maplins don't). There must be lots somewhere gathering dust since
everyone moved to the later 68k family chips (all I have spare are the stock
8MHz versions). Lots of non-home-computer stuff seems to use them (phone
exchanges, network equipment, video processing boxes etc.).
also, does anyone know of anything that used 68450 chips? (they're 4-channel
DMA controllers for the 68k apparently). I found a couple of these amongst
the piles of junk I have and am curious as to where I might have got them -
I can't think of anything I've ever stripped for parts which may have used
them! :-)
cheers

Well, all, I'm happy to report a few additions to my small
collection.
(1) DEC LA120 (DECwriter III). I bought this on eBay for a steal a
few weeks back. It looks to be in decent condition. The shipper
packed it very well, but neglected to wrap the LA120 in something
before adding the paper-strip packing material. Thus, the thing is
filled with paper strips, and I've still not taken the time to
disassemble the LA120 to vaccuum/pick them all out.
(2) DEC VT102. There was (and maybe still is) a lady selling what
is probably a whole room of VT10xs on eBay, at the rate of one unit
every week or so. I contacted her directly and asked if she had
any units for which I could make a direct offer. She did, and I
bought one. It was handled very poorly by UPS, as the top part of
the case came off and now won't go completely back on and the case
had several pieces chip off. It's not as pretty as it could be,
but it *is* functional, so I'm satisfied with the purchase.
In other news, I found some LA36 ribbons, LA120 ribbons, a box of
teletype paper, 1981 PDP-11/04/24/34a/44/70 processor handbook, and
a 1973 PDP-8/e/m/f small computer handbook, all for great prices on
eBay.

<< My wife wants to sell this printer in a yard sale, but the
collector in me is telling me to hide the printer in a safe
place.
Does anybody have an owners manual for this thing? I'd like
to know what the 8 dip switches control. I'm willing to bet
that they have the same functions as whatever printer Nakajima
licensed the design from (Epson FX?)
I know that it emulates an Epson of some sort, because I used
it on a PCjr a long time ago. It has a Centronics parallel
interface, and some sort of weirdo serial interface (Commodore?).
According to Nakajima, it might work using Epson FX or IBM
Proprinter III drivers.
The printer is interesting to me because I've never seen another
one, and Nakajimi is not a household name for printers here in
the US. ;-)

I wouldnt call it collectible, really. I have the SR3000 and it's a epson
fx80 compatibile i think. It is good if you have an apple // and run GEOS.
There are no drivers for the SR3000 that I had but it did support the SR2000.
Since it's come up, I've re-added the scans of the Super Star Trek sourcecode
in Basic from David Ahl's "More BASIC Computer Games". There's no link from
my home page, but the inside link will work. It is:
http://www.litterbox.com/jim/trek/
Be advised the scans are quite large - 300dpi - to make OCR work better.

I recently got my hands on a Laser 128 Personal Computer, but no way of finding out if it works, as it's missing a power cable, or possibly an external power supply?
It has DC 15V marked on the case over where the power cord is supposed to go, and 7 pins arranged in a circular pattern.
I need to find either pinouts, an actual cord, or the external power supply for it. Anyone have an idea as to where I can find any of these?
Thanks,

Does anyone have a spare TRS-80 Model II keyboard, boot disk, or manuals? I
got one of these wonderful systems today, along with the disk expansion
cabinet, but no keyboard, disks, or manuals. It seems to work fine, but
without a keyboard or software, I can't do much with it. Any help is greatly
appreciated!
