O.K. :-) Well, I guess your museum will be that much more appealing. I have
seen ads for many other computer kits, most have no name so I cannot
describe them. The Digicomp I and Geniac seem to be more known.
And yes, I would eliminate "logic trainers" too. I even saw a 74181 wired
with input switches and output lamps. The time to assemble it would vastly
exceed the time to exercise the 16 or so demo's!
Others are very simple, such as the 3 potentiometer "3 dialer" analog
"computers". I still have one I built in Jr. high school. (About age 14).

A lot of other interesting systems, too.

This info is interesting. He made a card reader to input "Monopoly" data. So
it appears to be 6 rotary switches made on the panel. Up to 6 poles, 16
position each. Amazing what could be "programmed"! Changing the "hard wired"
connections may be a chore if its wires under the screw terminals, did not
notice any place for a sort of a breadboard or "patch panel" to do this, or
that one would fit the scope of it anyway.
Thanks for all the information.

And this is bad? In the world of classic Land Rovers (mine turns 40 next
year), I and all the other enthusiasts would be up the proverbial creek
were it not for people out to make a buck -- the parts dealers, mechanics,
magazines, show producers, rally arrangers, etc.
Where would classic computers be without thrift shops, surplus dealers,
jameco, digi-key(?), heck, even eBay?

There was some discussion a while back on the [TRS-80 Model 100] m100 list
about that -- some one (a college kid iirc) had taken his apart and used
purple(?) spray paint to add a cool design to the case.
I always thought that was cool, but I haven't come across a computer I feel
comfortable doing that to. Yet.

I think I might have a large version of this. I considered it a logic trainer,
not a computer. The description of one of the blocks is the same. "There are 3
input sockets (A,B,C), one output socket (F) with a lamp next to it. Mine are
white, about 2" square. The leads are black with gold tips of three varying
lengths. I also have 6 different logic modules. I have a total of 30 to 50
modules and a couple of hundred leads. The large plug board is about 2' X 3'
and powered by 120V AC. I haven't checked the power supply but I think the
voltage on the logic units is about 2 or 3 volts. The whole assembly fits in
its own wood travel case with handles.
I have never found any info about this. There is no manufacturer's label
anywhere on the units.
I will try to get pictures of this in the next few days. Thurs. & Fri. I am
out of town, it may wait till I return.

generally in OS design there are only a few significant extensions
(filetypes). the most common are:
.EXE (executable, generally fixed address)
nearly always a binary loaded at a nominal standard address.
.COM also executeable but vary in composition
Can be a binary, often in DEC systems it's a command file (SCRIPT).
.SYS commonly drivers or system specific and usually loads differently
(unique address or relocated).
Most others are application specific and the OS treats them as "files"
and it's up to the apps to do the right thing. Clearly Windows has
carried that to the opposing extreme such that the extension determines
the action but that is not at the file level it's at the command
processor (GUI) level. Likely the extreme at the other end of the
spectrum is CP/M-80 where .com is significant to the command processor
and all others are only significant to apps. It allows for TYPE FOO.COM
where FOO.COM is a binary that would load at 100H and looks like Greek
on a vt100.
In most OSs at the basic file level (FILE SYSTEM) one type is the same
as another. the differentiation often occured at a higher level where
the user command are interpreted and acted on. Exceptions abound but,
they often do not add any value and are system specific. One that comes
to mind is NS* DOS and the OS/FileSystem and command processor are so
tightly bound that they live as only monolithic 2.5K(or so) block of
code. It has some economies but ofthen its simplicity is a trade off.
An alternate to this is having file information inside the file as a
header block that binds the file to it's respective application. Correct
me someone but I think the Apple MAC OS does this. It removes the need
for the extension driving the application.

Someone i know came across this machine and asked if i could restore it.It is a Laser 128 I know it is an Apple II clone but what else can anyone tell me about it.I have cleaned this thing out(it was filthy)But cant start it up because i have no power cord to do so any info will be of great help

Way better? I would say simpler, the 64 was more complex in design but was
par woith the machines of the time (Atari and Apple) where the VIC-20 was
lagging at that point. And you guys mention graphics which were good, but it
took YEARS for anyone to match the 64 in the sound depertment (first the Amiga
then later the Soundblaster - was about to say IBM, but the big computer co.s
had nothing to do with quality sound development on that platform.)
Though it is sure easy to read that 22x23 character screen! I did with a
VIC-20 and a datasette for a year, it sure teaches one to code tight.
In reference to the memory question some VIC/VC REUs went to 24k (like the MSD
one I have here), but there was also the Aprotek RAM expander/cartridge
expander which filled every gap, all the contiguous memory (including the 3k
portion in lower RAM) as well as the upper 8K Game ROM space. 32k? I think
they gave it a bigger number, maybe by adding the 5k and the ROMS to the
'total memory', regardless, the Aprotek one was the ultimate in VIC-20 expanders...

I hear of more of the P/B500 in europe then here, actually in the U.S. I think
there are maybe three or so around, since they never were oficially released
past the late prototype stage (due to one of Commodore's run-ins with the
FCC). Dunno how many (if any) they sold in europe.

Before that the 'color computer' Commodore was developing was referred to as
the TOI. I have read in one place that the TOI unit used a different video
chip (recommended by Peddle?), but it could just be a rumor. I recall my
first seeing the TOI article in a Cursor tape newsletter (paper portion),
anyone got that issue?
