Last month Tony Eros was asking about documentation for the
DCT11-FM T-11 evaluation board.
I don't have any documentation, but I do have one of the
boards and am in the process of creating an annontated
disassembly of the monitor program.
I would be happy to share this and/or compare notes with
Tony and anyone who is interested.

I got mine from a friend. He was moving and didn't plan to take it with
him. So he said I could come get it, but had to remove it from his
basement. It is about the size of a thin desk, and weighs maybe 200 lbs
(it is a table top like design, not the more stereotypical upright as
seen on Happy Days).
So I arranged to get a pickup, and a few large friends to help haul it
>from the basement. When I arrived, I found that my friend decided not to
wait for me, and had put it out on curbside. I last spoke with him a week
earlier, so I'm not sure how long it had been there. It had been raining
all week to boot!
The top had been opened by someone else, and any of the 45's that were
reachable had been removed, as well as much of the carousel had been
damaged from attempts to remove 45's that weren't reachable.
Needless to say, I was pissed!
But I took it, and spent the next two weeks on my back inside the thing,
taking it apart, cleaning the rust, and repairing damaged parts. (I
lucked out, the service manual was still inside, and remained mostly dry,
so it was readable).
It runs 99% fine now, and sounds pretty nice (very nice for an early 50's
sound system, but obviously not quite as good as my surround sound
system). The only problem it still has is one of the carousel selector
sensors doesn't always make good contact, and if you try to play the 45
in that slot, it sometimes get stuck and just keeps spinning, never
selecting the record. My guess is a spot of rust (much of it was rusted
when I worked on it), but it is a pain to remove the unit, so I have
ignored it for now.
I still of course have to refinish the outside, as it was just totally
damaged in the rain (the chrome plate rusted and bubbled off, the
woodgrain siding peeled, and some decorative trim came unglued). When I
buy a house, and have more room to work on it, I'll refinish the
outside... but for now it lives at my parents house, and they just can't
have nice things, so no sense fixing it up just for them to trash it
again.

pay postage.

Since I only have the one acoustic player, I can't say for all designs.
But my Victrola has a weight already attached, and a pretty heavy one at
that, so I wouldn't dream of doing such a thing. As is you have to tilt
the needle down into place gently or it will tip and slam the needle into
the record pretty hard (hard enough to put a nice puncture wound into a
finger as I learned from experiece).
Although, I know of people doing that with arms for newer analog
turntables. But then in every case it was either because the person had a
REALLY cheap one, or they didn't realize that there was a counterweight
on the back of the arm already (I've seen a few where the weight is under
the plastic cover to the arm, so it isn't obvious its there... my Rockola
jukebox is like that)

I have approximately 100 issues of MacUser from 1991 - 1997. Anybody collect
these? Free for pickup in Austin, or will ship at your expense (book rate).
Will put in dumpster if nobody wants.
Thanks,
Terry

I was just viewing your site. I was wondering if you or anyone else would be
interested in a Xerox 6085 System and a Xerox 4045 Laser CP Printer. Items
included are: the Xerox 6085 CPU, 19" monitor, keyboard, infrared mouse,
external 5 ?" floppy disk drive, Xerox ViewPoint Series Software (on 5 ?"
floppy disks), additional 5 ?" floppy disks, Xerox 4045 Laser CP Printer,
printer cable, and user manual for printer. Both are in working order. We
have some photos available that I can e-mail to you if you are interested.
We were thinking about putting the items on eBay, but haven't done so yet.
If you would like to make an offer, please do so. I look forward to hearing
>from you in the near future :-)
