Actually there's quite a lot of really good Commodore 64/128 stuff there...

the 128D is a nice computer when you find one that works reliably. $30
> 1- Super CPU 128 with 8 Megs installed. Will put the 128-D at 20 mhz.
This is a 20 Mghz accellerator for the 128, it was just put on the market this
year. Probably good for $150 alone.
> 1- CMD RamLink with 12 Megs, includes the HDD Cable and battery backup.
Nice REU unit, does a RAM disk with it's memory and allows for fast parallel
access to CMD Hard Drives. Another $100.
> 1- 1581 Disk Drive... with Jiffy Dos
Somewhat hard to get maybe $40 at best.
> 1- CMD FD-2000 Disk Drive. 1.6 meg floppies yeah!
Improvement over the 1581, lets you also use 1.44 md disks and with right
software access IBM disks too. $75.
> 1- CMD 2 GIGAbyte Hard Drive that looks CHERRY New!
A CMD Hard Drive for your Commodore 64/128 is a must for the commodore fan,
Probably about $200 at most.
> 1- Commodore 2002 40/80 Color Monitor
Nice Monitor, can be used on Amigas too... $40.
> 1-1541 Disk Drive... Yes, WITH Jiffy Dos
> 1- 1571 Disk Drive with.... Jiffy DOS!
> 1- C64c Computer
Ok, I guess... Not too terribly exciting there... Maybe $50
> 1- Action Replay Cartridge (believe its v4 or 5)
Get $15 probably from me, I prefer Super Snapshot myself.
> At least 30+ Origional Programs
'Paid for Software' A buck a piece without knowing what it is... $30
> A whole GEOS COLLECTION, Origional in boxes.
I'm not much of a GEOS Fan. I could resell it for probably $20... Though
with an original GEOS 64 2.0 disk I coulde upgrade to the recent GEOS upgrade
- Wheels, which sounds pretty hot.
> Over 300+ 5.25 floppies, all kinds o stuff.
Read Pirated I'd go up to $30 hoping there would be a few gems of 64 software
lore hidden away.

Lifetime, no, Heck I could collect that all in a year at a fraction, just try
to find docs for a PET MTU graphics board (like I am), I have a collection of
a lifetime.

Total about $765 dollars, not to say I would bid on it, but, it is a nice list
of equipment, and the current price is not all that out there. You can tell
by the list the guy was either a Commodore BBS sysop or heavily into GEOS,
only those two groups buy heavily into RAMLinks and mass storage units. I
Don't recognize the name Ice BBS though.

I also have a neat XT. It's not a Phillips, but a Tandy 1000. It has 768K
RAM, and a 12MHz 286 processor. Only, I still have the problem of not
being able to access the upper memory. Being a Tandy, it's even harder to
find a driver. Another setback is it's HD. It's a 20MB Western digital -
and slow as a turtle. Does anyone, by any chance, have a spare
XT-compatible IDE HD without a stepper motor driving the heads??

Amen to that. Heat is a bad thing for computers or their peripherals.
Most suffer from to much heat, and too much heat around the disk stack.
< Those ST251's have rapidly died out around here,
Actually I'm still running one, in a Leading Edge model D Xt box that
does cool exceptionally well. The power supply (and the fan in it) is
behind the disk stack and exceptionally well cooled. I put a second fan
in the 486/66 for that reason... to hot.
The altair taught me well about heat... and lousy air flow.

A minor success story compared with some I read here, but I wanted to
share it with you...
This weekend I finally got my Tektronix 4052 graphics computer loading
and saving on a Commodore 8050 disk drive. The problems:
Commodore's weird handling of IEEE-488 protocol, especially with OPEN
and CLOSE. This requires bit 7 (the 128s bit) to be set when sending a
secondary address; bit 4 - usually the 16s bit of the address - tells
the drive whether it's an open or a close.
This was easily solved - the Tektronix WBYTE statement gives full
control over such things.
But the Tek is designed as a tape based machine. You FIND a file on the
tape and type OLD to load it. The machine then resets and loads the
program.
On a disk, you WBYTE @40,240: some bytes to specify the file name. But
if you type OLD @8,0: it asserts IFC during the reset, thus causing the
drive to have forgotten all about your program by the time it comes to
load it...
So I toyed with the idea of cutting the IFC line in a suitable cable.
But then I came across the APPEND statement. "APPEND @I/O address:line
number" loads a program without resetting, renumbering it to start at
the specified line. Neat.
So I now have a program to display the directory of the disk, prompt you
for a filename and APPEND the file on the end of itself. It then
performs an INIT (initialise variables, IFC and things) and drops into
the program.
Saving is easier, so less automated. You type something like
WBYTE @40,241:48,58,80,82,79,71,82,65,77,32,78,65,77,69,-13
WBYTE @63:
SAVE @8,1
WBYTE @40,225,63:
Not perfect, but it works. If anyone has an 8050 at the VCF, I'll
happily demonstrate!
Now, has anyone got a PET hard drive? And, for that matter, has anyone
got a MUPET system for sale?
Philip.
OK, I've read through the entry on the DLV11-F in the "Microcomputer
Interfaces Handbook" (I love finally having some documentation). According
to it this card supports either a 20ma current loop interface or
EIA-standard lines, but doesn't include modem control.
My first question is, am I correct in assuming that I can attach a VT100 to
it with the proper serial cable? I know I could use the 20ma current loop,
IF I had a VT100 with that interface.
Anyway does anyone have the pinout for a BC01V-X or BC05C-X modem cable?
My guess is that it's a 40-pin ribbon connector on one end and a DB25
connector on the other. Unfortunatly I don't seem to have the pinout for
the 40-pin connector or I'd see about putting this together.

I acquired a PDP-8/L not too long ago, and in discussion with the
original owner he advised I have a fire extinguisher on hand when I power
it up.
That concerns me, as I'd rather not burn up a PDP-8/L (or the house).
What can I do to ensure the -8/L wont catch fire (or do anything else
equally bad) when I turn it on? I don't have a very good knowledge of
electronics, but I can certainly open it up and examine boards.

What?!? Took me a couple of minutes to work out what you're even
talking about, there.
These (mostly non-electronic) analogue computers were quite popular in
larger cars (in the UK, anything with more than 2.5 litres - 150 cu. in.
- of engine) in the early 'seventies, but they were inefficient and
unreliable and I never use them if I can avoid it...
I refer of course to automatic gearboxes. If you want control over the
transmission shift points, get a manual gearbox with electric overdrive.
Every time!
(Hmmm. Thinks... I don't think I've seen an electric overdrive on a
car made later than 1980. But automatic gearboxes are still alive and
kicking. It's a strange world...)
