Homebrew PCBs

I am not 100% sure, but I believe I am recalling correctly!

If you have watched that TV show LOST, then you are familiar with the 
bunker they found. Inside was a computer used to control the "power 
source" for the island.  Well, correct me if I am wrong, but isn't 
that the same computer Jan is using with his PCB mill?

Just made me smile when I thought about it.

Chris and others:  That is a Commodore "PET" the first  
commercially-available "home computer" with the keyboard, motherboard (ONLY  board!), and monitor 
all built into ONE unit.  The EARLIER model had a  "chicklet" keyboard, making 
room for the cassette drive next to the keys, TRULY  "all in one"!  
 
The first PET I had lasted until about '92.  Then CBM  went bust, and I had 
an opportunity to buy FIVE replacements for $100 plus  shipping.  Old age took 
those out one by one, over the years, and the last  one to operate this drill 
finally just quit functioning.  I have a nice,  working, old '386 "minitower" 
and a monocolor monitor with a Parallel Printer  Port ("LPT-1") I will use for 
that, now, but I have to re-write the CBM BASIC to  GWBASIC which the '386 
can understand.  ONE old person, NOT enough  time!   (This machine would drill 
about 1 hole per second.  As  you can see, totally home-brew!  Quill is 400 Hz 
"aircraft instrument  motor."    The little blue motor on top drives the "Z" 
(0.250"  down/up)  ramp.)            Jan  Rowland

Ah yes, the Commodore PET/CBM. I spent many great hours on it. I still have
mine in storage. A great machine of the Apple / TRS-80 personal computer
era.

The Commodore was a 1 mHz 6502 CPU with 32K RAM and the OS in the 32K ROM, a
640 x 400  12" green  CRT with an IEEE port. All of this for only $1295!

Of course, you had to add the dual 1 meg Floppy Drive for only $1295 and the
dot matrix printer for an additonal $995. Word processing software was only
$495.

Not bad, a complete home computer / test based word processing system for
only $4K, and those were the 1980's dollars.

The Commodore has been seen in a number of TV shows and movies. In fact a
chrome platred model was on Capt Kirk's desk in one of the early Star Trek
movies.
