It appears my last post may have contained at least one ambiguity.
In each case where the number of available items is more than one,
the price is for EACH. For example, for the 2 boxed sets of original
software, the price is $30 for each box. I apologize for any
confusion.

OSBORNE 1 AND EXECUTIVE COLLECTIBLES
Hi,
I've decided to focus my collecting on Apple items. Therefore, I have some
Osborne collectibles I'd like to sell. I thought I'd give this group the
first shot, before going public.
All items are AS IS, subject to the descriptions given. Nothing is warranted,
except that the items are as represented. Prices do not include shipping

upgrade. Startup screen displays with extra characters (zeros), and
attempts to boot a disk result in boot errors..........$75
1 Osborne-103 "internal" modem with manual and software. Blue plastic, fits
in pocket below left-hand disk drive. Missing ribbon jumper cable

I was just given a Sony SMC-70 last weekend by a friend of my son's that is
moving. The machine has 3.5" single-sided floppy disks, both black & white
and RGB video outputs, an RS-232 interface, parallel interface, and a DB-25
connector labeled "external drives". It also has a "supercharger" unit with
it that contains an 8086 processor. This "brick" plugs into the back of the
SMC-70 using a centronics-type 50 pin cable. According ot the
documentation, when this "supercharger" is plugged in, the Z-80 processor
in the main unit handles all of the I/O functions and the 8086 becomes the
default CPU. The system uses either CP/M (in Z-80 mode) or CM/M-86 (in 8086
mode). I have manuals and documentation for the machine, the Sony
applications, and the CP/M and CP/M-86 operating systems, but the original
system and applications diskettes were not passed along to the person I got
the machine from by its original owner. Anybody have any idea where I could
get at least the OS for this thing? It looks like a neat little machine.

That's what I did (in most cases).
The modulator typically has 3-5 connections. They are :
Ground (connected to the 0v line of the computer)
Power (typically +9V - +12V)
Video Input (Composite - jsut what you want)
Channel Select (in the US - connected to the Channel 3/Channel 4 switch)
Audio Input
Most modulators are standard parts, and you can get data on them (or at least
a pinout. I'm unlikely to be much help here, since I'm in the UK, and our TV
system is different).
Anyway, you need to identify the video input. Either look at the modulator
data sheet, the schematics of the computer or trace it out by hand (eliminate
the ground and power pins, and look at what's left).
I've just found the (USA) CoCo Technical manual. The modulator has 5
connections, including the case. It's a UM1285-8 (I suspect that this is used
in other computers as well). Anyway, the connections are :
Case - ground
1 (Nearest the RCA socket on the modulator) - Video Input
2 +12V power
3 Audio Input
4 Channel Select
Now connect a piece of 75 Ohm video cable with the centre wire to the video
input pin on the modulator and the braid to the 0V line. Connect the other end
of that cable to the monitor.

Got a simple question. God I hope it's simple and does not turn out to be
an advocacy question. Im planning my "museum" setup. I have alot of
machines that were simply designed only to work on Color TV's. Is it
possible to just tap the input's before they get to the RF modulator {built
in} and use a composite monitor, of which I have dozens? Otherwise I've
got to buy, scrounge, find, about 9 color tv's.
Once I try it myself, sure. All I planned on doing was desoldering, or
patching onto the input of the RF modulator, {the 1.5x2in box that you plug
your tv into) to a composite RCA style connector. Hoping this will work.

I have a pretty good inventory of these types of things, let me know
exactly what you need, and I'll see if I have one. I may not have original
IBM, but I can get you up.

'Coconut' was certainly the code-name for the HP41
I also like the HP71B. They're very easy to find in the UK at the moment, and
tend to sell for about \pounds 20.00. Forth/assembler ROMs are a lot rarer,
though, but the built-in Basic is quite nice.
I was very lucky - I managed to obtain all the technical docs on the HP71B,
including a commented source of the ROMs. It's a very interesting machine
internally. The Saturn (which is used in a lot of later HP handhelds,
including the HP48 family) is a strange chip. I'd not call it 20 bit, though.
Addresses (nybble addresses!) are 20 bits, most registers are 64 bits, and the
ALU is (I think) 4 bits. Call it whatever size you like.

This I consider a big item. Some of the classic machines are significant
in their simplicity or usful in that you can point to identifiable
elements (ram, ALU, CONTROL). I frequently use the PDP-8 design for this
as it's very simple and the instruction set is about as minimal as can
be and still be useful. The same can be asid for some of the 8bitters as
well.

Does the floppy drive LED light up during startup? It should, whether or
not the HDD works, and you should be able to boot from a floppy, even with
a dead HDD. Therefore if a boot disk doesn't work, either your floppy
system is defunct or it's in the motherboard.
An easy fix -- which doesn't always work -- is to disconnect and replace
all cables. It's fairly easy -- pull cables one end at a time *only*, so
you don't forget where they went.
Each device has 2 things going into it...a flat (usually, grey, sometimes
blue) ribbon cable, for the data; and a power cable. Both are keyed, so you
can't put them in backwards.
Trace the data cable from the floppy(ies) back to the controller card, and
pull & replace. Those are usually pins, and *can* be replaced backwards, so
take care. You can swap the controller card into another slot -- any slot
should work. If all slots are filled, exchange two cards.
Chips work their way out of their sockets ("chip creep"); push every
socketed chip back in.
I have boxes of cables, controller cards and drives if you need any; e-mail
me.
If the floppy disk does its thing, are you sure the floppy itself is OK? It
must be low density (you can tell by the hub ring) and have the proper
files; try booting another machine with it. Not all DOS's will work on all
machines -- I've even seen some older machines that won 't boot under DOS
6.x
