Don't know in this case, but its still money to earn.
Every cent is at least 1/100 of a dollar.

So, what's the deal with copyright on schematics? If someone can sell
them and make money out of them, is there any reason why they can't be
scanned and put on the 'net for free? Or do companies that sell such
information pay royalties for every schematic sold or something??

As a retired moneychanger turned storyteller, fighting against government

I need to dispose of 'assets' to pay Sancho Pansa's wages.
'Assets'? available:-

I have recently dug out the above items which were purchased new in 1975/6
(whilst working as a moneychanger) and were working when put into storage
in 1980. There is also a quantity of advertising literature and
instruction manuals relating to all but the Mesonix Tape unit
(a U.K. company that no longer exists?)
Still in store there are also three complete Cromemco systems one System 1
(or 2?) and two System 3's with four or five terminals, a stand alone
double 8" disk drive, a Cromemco Spinwriter and Quime daisywheel printer
plus a mass of Cromemco software, manuals and disks.
S100 - a bit like tilting at windmills.
I'm thinking of eBay for disposal of anything of any real value but would
appreciate the helpful comments of any classic computer cognoscenti
/collectors/dealers out there, willing and able to assist.

Immediately following my success with the Mac yesterday, I got to work on
'fixing' my portable '286 box with LCD display (which I think is _barely_
classic).
The cable leading to the display had had three of its wires pulled out,
and I figured that this was the reason for the very weak and grungy
display.
I managed to solder little bits of wire into the holes and solder the
stray wires from the cable onto those, but then I realized that I couldn't
plug the thing in anymore as the holes (from the underside) had filled
with solder. :/
And I also realized that my solution was a bad one because the protruding
wires would short against the metal frame that holds the LCD panel in
place.
So I used the connector from the C64 keyboard instead.
Anyway, I got the cable rebuilt. I've tested it with the multimeter and
all the wires make contact and go to the right places.
But now I can't get any kind of display from the LCD panel. It doesn't
light up at all. It looks like it's totally dead.
I put a monochrome display adapter card in the machine, and it will boot
up with that and display fine on a monochrome monitor. So the machine is
_mostly_ OK.
I'm not sure the power supply is OK, though. It squeals now.
So basically, I've turned an ill-looking display into a dead display, and
for some reason a healthy power supply is now sounding sick.
Bleah!
Anyway, the machine has a special card in it for driving the LCD panel.
It is labeled "LCD & HGC CARD". What is "HGC"? It has an external 9-pin
port on it and I tried plugging the monochrome display into it, but the
picture was all distorted so I figured it was using a different frequency
or something. The cursor comes out about an inch wide, and none of the
craracters are recognizable, possibly just from overwritten numerous times
in the same scanline.
I don't know where I'll go from here. I'm just taking a breather
before continuing. I wanted to be rebuilding the TS1016 RAM pack by now
instead of still messing with this damn PC. <s>
Oh, and BTW, I electrocuted myself last night when I touched some exposed
wiring going to the LCD panel. It surprised me that there was that much
juice going through there. My thumb and forefinger are still tender. But
the display was still working at that point, and looking much sharper than
it had been. But the machine wouldn't close up properly because the
connector was too thick and that's why I went back in today, just to
reverse the cable so that the big fat Commodore connector was on the
inside instead of on the LCD panel end. (Which meant pulling the connector
apart and rebuilding it the other way, just so it would fit in.)
I haven't crossed any wires, I haven't plugged anything in backwards, and
I haven't dropped anything into the machine, so I don't know what I've
done wrong.

Just got a PDP-11/84 into the basement, and after the Series/1 experience I
was ready... Go grab some 2x4 lumber if you ever need to get a rack system
up or down stairs... Now that it's down, I need to get it running. When I
plug it in and turn it on, it turns on the "DC on" light and the boot test
display says "77". And what is the easiest way to hook up a
terminal(probably use a WY-99GT or VT-220, maybe the WY-60)? It's a nice
system with 4MB RAM and a 9-track Cipher tape drive(I noticed that the tape
drive I have with my Series/1 appears to be a Cipher, or based on it as it
needs a Cipher tool to prepare the tape for the autoload feature). Any
ideas on how to hook the tape drive up?

Try American Ink (<http://www.americanink.com/> I believe); they carry
ribbons for a lot of older printers. (Ran across them while researching
one of the computers in my collection on the web, but have known of them
for years; very highly recommended in local Atari circles.)

Hey, my Mac 512K is now working!
In fact, I'm using it to type this message.
Instead of going out hunting for more expensive connectors, I decided to
use a dead C64 for parts. I pulled a male 9-pin D connector out of there,
and while I was doing so, I also noticed that the C64 cartridge connector
might be useful for repairing my TS1016 memory cartridge for my Sinclair.
I don't think I'll go to hell for cannibalizing a C64. Besides, C64s are
cheaper than the useful salvageable parts inside.
Anyhow... I made a Macintosh to Amiga mouse adapter. I got the two
X-direction wires switched around the first time, but it's all working
now. I decided to use the lessons from the Laser 3000 and I poured hot
glue onto the wires after they were all soldered into place, so that the
thing is rigid, and then I wrapped it in electrical tape. :)
So my Macintosh is presently using a two-button 'Pregnant' Amiga mouse. I
should try the three-button optical mouse, but what would be the use of
having TWO useless buttons? :)
This is also giving me a chance to try out that old 1200bps Apple modem I
pulled out of the Goodwill a couple of months back. Obviously it works
pretty well! But I'm not used to this level of slowness anymore.
I'm also not used to using Pico without arrow keys. Who's idea was it to
use ^B, ^F, ^P, and ^N anyway? Couldn't they have at least arranged the
keys in some sensible manner?
It took me a couple of minutes to figure out how to configure the Option
key to work as Control, too.
I don't know what I'll do if I have to use ESC for anything.
Did Apple think they were doing someone a favour with this keyboard? :/
Anyhow, I'm glad to see this thing works. Eventually I'll get around to
fixing the real Macintosh mouse.
Now... my display appears to be squished slightly on the left hand side.
Can I fix that easily, without risk of electrocution?
And what about that MacSnap SCSI board? Do I need special drivers for it
or something? I can't get it to see my Zip drive.

The video cable you have is probably for a Commodore 64, Atari 8-bit, or Sega
Genesis. There are two video outputs on the VIC video connector.
You should be able to locate a cable that has a 5-pin din to 4 RCA type plugs
- Radio shack used to sell them - I think they are (were) used in automobile
audio systems... With that you will find both video and audio output (but
watch out, there is also the +5v output in one plug too.) :/
BTW you're not missing much with the VIC-20 sound, the programmer's trick to
get better sound output is to keep the computer controlled sound volume low
(like 2 or 3) then the voices don't mess up each other as much.
