the (more common) Commodore 64 or 128. <<

>I'd like the Pinout!!<
First, the Commodore 8-pin DIN connector is the unusual one; the "Hershman"
or something. This means that pins 7 and 8 are not in the same positions
as on the common 8-pin DIN connector. (Look at the port to confirm pin
placement; I'm not sure the chart below is correct.) One easy solution
here is to cut pins 7 and 8 off a common 8-pin connector; they aren't
needed for anything. Or as explained below, you can use a common 5-pin DIN
connector; but, if you're hooking to a separated color composite monitor,
your picture won't be QUITE as sharp.
Looking at the port on the back of the computer, OR at the BACK of the DIN
plug (the side you'll attach the wires to), the pinout is:
8 7
3 6 1
5 4
2
Connections are:
1 Luminance
2 GRND
3 Audio
4 Color Composite
5 Audio In (not used)
6 Chroma
7 NC
8 NC
Hook up pin 3 for audio in all cases. As to video, if you're using a
separated color composite monitor, do separate RCA plugs for 1 and 6. If
you're using a color composite monitor with the single input, use 4. If
you have monochrome, use 1. If you want to use a 5-pin DIN connector with
a separated color composite monitor, do separate RCA plugs for pins 1 and
4.

>> (the early models had a 5-pin port) will also work on a Plus/4. In
fact, I think most home computer manufacturers (Atari, TI) used 5-pin
cables with
the composite, sound and ground on the same pins, so you could try one of<<
>I have a TI/994a converter box...will this work?<
The TI 99/4a doesn't have an internal RF modulator; that's what the box
does. So even on a TI, you only need the box (and can only use the box) if
you're hooking to a TV. The Plus/4 has an internal RF modulator, so if you
want to hook to a TV all you need is an RCA-RCA cable and an ordinary
game/TV switch. I *assumed* (and we all know what happens when we "ass u
me") that when you said "video cable", you meant a monitor cable. As I
said, it's the same as the C64 and some other computers use, so it
shouldn't be all that rare. I'm sure anybody could sell you one (including
me) for $5 and postage.

Well, Gil, I used it as a learning project. When I first got my VIC-20 in
1981/2, I was in junior high school. I programmed mostly in BASIC, and did a
little ML. After I graduated, I got involved in too many other things: my
fraternity, my wife, a job, the Mac, and then Windows hacking. When I bought
my house two years ago, I moved all of my old machines and started playing
with them again.
So...I wanted to re-learn 6502 ML and the VIC/CBM architecture. I thought
that documenting the VIC Kernel (some thing that I had never seen in print)
would be a nice project. Also, I thought that it sould be good to have
recompilable Kernel code, if I ever needed to recompile it. Documenting the
Kernel enables the programmer to understand what's in the "black box." This is
why AndrewShulman and Matt Pietrek have made a fortune in books detailing the
internals of Windows.

Incidentally, I built a PSU for my PC-jr last week.
I used a simple 15V AC transformer, no centre tap or anything like that. The
only one I could find was 50VA, which is marginal, but not too bad.
The ends of the secondary go to the outside 2 pins of the PC-jr power
connector. The central pin goes to mains earth and to nothing on the secondary
side at all.
Oh, I put a 3.15A fuse in series with the secondary to protect the transformer.
It works fine. My PC-jr boots, and all PSU outputs (including the -ve one) are
present and correct.

You pay UPS for 7 lbs from 93405. Printer only, no interface cable. Was
used with C-64. Untested but looks good.
Check the <a href=http://www.ups.com/using/services/rave/rate.html> UPS
Rate Calculator </a> to figure shipping. And be sure to add about $1
because those quotes are commercial pick-up rates.
Was there some bloke on this discussion who was asking for the Hayes
micro-coupler the other day? I have an extra one if you still need it.
E-mail me.

I have the following Commodore stuff for sale. Discount for more than

VIC-1541 Drive (2 ea) $5 ea
1541 Drive (2 ea) $5 ea
C-64 in orig box w/ps(1 ea) $5
Commodore joysticks (1 pr) $5
Untested C-64 Power Supplies (6 ea) $3 ea
Remember to add shipping to what its worth to you. Use the UPS site:
<a href=http://www.ups.com/using/services/rave/rate.html> UPS Rate
Calculator </a> to figure shipping. And be sure to add $1 because those
quotes are commercial pick-up rates. Drives and C-64s are about 11 lbs
ea. My ZIP is 93405.
I also have a pile of cables and stuff that I haven't look through yet.
Will throw in whatever cables and manuals I can find that go with each
item, no guarantees though. Also, Im pretty sure I ran all these but not
positive. I don't have time to test all this stuff. Sold AS-IS.
Make me an offer on all or some of it! It's going to go one way or
another so if it doesn't sell, I'll give it away for shipping cost. If
that doesn't work it shall return to the thrift store from whence it
came!
A while ago I promised two people that I would fetch them some IBM PCjr
power supplies if I ever found them. Well, I found some today. I've got
two up for grabs. Please e-mail me if you were one of the two people who
inquired about one. If you weren't, e-mail me anyway and I will send
them to you if the other two guys don't respond. To the two guys whose
names I forgot: sorry for forgetting your names!

Slot 13 bottom is not the HD controller, it's the distribution card. There
should be a 50pin cable bettween the m9058 and the m7555(rqdx3) card.
Pull the m3106 and bump the rest up one with the last one being the m7555.
It shouldn't make a difference but at this point you don't need it to boot.
This will give you a minimal config for the bus. Also make sure the overt
the top cable for the memory is good!
