Geez, I'll bet that that one smoked! Sounds like just what you need to
run Windozes '95 effectively.

How about the iMac it has networking built in and AFAIK doen't run MS stuff.
I think that todays machines are so versatile that it is pretty hard to
differenciate them out of the box, The way they are used makes them a
workstation, a server, a personal computer or what not, not the hardware
itself.
I'll give a LIFETIME PASS TO THE VINTAGE COMPUTER FESTIVAL to the first
person who successfully gets me in touch with CHUCK PEDDLE of
6502/Commodore PET fame.

Hi Group:
Thanks to Rick Murphy, I have the answer to my query. Turns out that the
info was also on my own website, in the RX01/02 maintenance manual. I
should've looked there first!
See http://highgate.comm.sfu.ca/pdp8 for pdp-8 docs, software, and other info.

him about these mags. I have no connection with them or with him.

Don't know if I'd actually classify this as a 'rescue', since probably the
worst that would happen would be that the gear would end up buried in my
warehouse, but...
A couple of items that could use a new home. (just cause I don't have
time to get to them at present) I won't attach a specific price to either
but would like to see either a little $$ or something interesting in trade
for them. (see the 'wish list' on my web pages for ideas)
Both items are considered to be in 'as-is' condition. I've not had time
to try to fire them up or do any check out since they came to me.
Either would need to be picked up as they are too large (&/or) heavy to be
practical to ship economically.
1) Cypher 9 track tape drive. 800/1600 bpi, 125IPS transport. Just the
drive, no cabinet.
1) DEC PDP11/84. CPU only in 4ft. cabinet suitable for mounting drive in
top bay.
Drop me a note if interested. Note: my ISP is having problems with their
dial up lines (darn US West anyway!) so my access to email is a bit
sporadic at present... So don't panic if I don't get right back to you...

BIG TRAK
grrr, i always wanted one of those things! it had a keypad where you punched
in coordinates and then it would carry them out. it also had lazer guns which
you could also program to flash i think. there was an optional dump trailer
too. im sure you could probably find one on epay.com for serveral hundred $.
came out in the early 80's i believe.

Similarly, does anyone remember a truck-like thing (big trax?) that you
could program sorta like LOGO? I remember the commercials showed it
bringing a soda (or beer?) to one lucky owner. Unfortunately, my family's
gift budgets never would have covered such a nifty gadget... 8^( >>

If you're after schematics for Commodore micros, check out
http://www.funet.fi/pub/cbm/schematics/index.html
There are schematics for the C128, C64, VIC-20, Plus-4, PET2001, PET8032,
KIM-1 and various peripherals such as floppy disk drives, printers,
datasettes, etc.

I must comment that the real distinction is how they are marketed.
Earlier, the size of the machine denoted its power and utility. Now,
it's not possible to classify as easily. Plus, hardware gets outmoded
so quickly, it's not likely for anyone to buy a 'mainframe' these
days. PCs are pretty disposable now. Tony's rules are adequate, as
these distinctions closely mirror the target market of the machine.

Maybe, or it can be a single board computer installed into a dedicated
application. Generally term embedded means dedicated to a task(or set of
tasks). One possible embedded machine is a national Nibble Basic or
intel 8052ah (basic or forth) chip with a keyboard, LCD and EEPROM.
