<Wow! A high schooler who's into old computers? Unless there is a
<pre-pubescent teenager on this list, I think Daniel has the record as the
<youngest collector of old computers.
Frightening. ;-)
here are some numbers
If you are in highschool now:
-0 PCs are known as current
if highschool was x years ago:
1990 PCs and macs
1985 Apples, macs, Rainbows, PRO350s maybe some PCs
1980 s100, apple][, swtp, LSI11, micronova Microprocessor chips
1977 PDP-11, vax, nova Some LSI and bit slice
1971 PDP-8, PDP-10 TTL mostly, some utilogic and transistors
FYI the main computers in the shuttle are this era technology.
1965 PDP-5 Transistors.
1960 First generation transistors, vacuum tubes
1952 first commercial machines, tubes
1947 prototypes, tubes and relays
If you were like me and did electronics as a kid following on to a career
then everything made from '64-65ish on was current at one time or another
to me. Then again I went to the NY worlds fair 1964/5!

Does anyone know what software is required for the Apple II SCSI card??
I got the card last week from a friend of mine, but without SW.
Apple's ftp site has only a "SCSI Utilities Disk", but the description
says nothing about "drivers". Alltech Electronics carries a new CMS card
with SW, but for $40. Seems that I should be able to get the Apple SW for
less than that...
Any clues appreciated!

I can verify that *some* floating point functioncs (basic ones ususally
ie +, -, etc) can be emulated faster than the stock 80387 or 80387sx
co-processor can do them. The majority of functions can not be emulated
faster though.

You don't need it. There isn't much to see.
Probe the board for +5 and -5 power if either is missing track it backwards.
the keyboard is powered off +12v from the system and there is a +5v
regulator on the board (7805, TO220) if that's ok then check for -5v(or so)
on the RS423 driver chip(9636). If that's there then probe the 8051 for
valid reset and crystal osc running. There isn't much to them and the key
is the 8051 microprocessor, if it's fried then look for a keyboard that's
mechanically trashed. Coffee, mechanical damage and ESD are the common
failure mode.

In 83-85 (high school), we had mostly Apple IIs, and a DEC dot-matrix
terminal to access a time-shared computer somewhere. In Jr. High (81-83), we
used mostly Commodore PETs (mostly the 4016 and 4032). AFAIR, there were no
Tandys or Ataris

Ok, time for those write-ups to start pouring in. I understand if you
didn't have time to do it but could you let me know if you were supposed
to do one but didn't so that I can plan appropriately? Thanks!

hey,
sorry but my english is very bad.
I found the address
http://staff.motiv.co.uk/~kevan/classiccmp/1997-08/msg00233.html
I have a Olivetti M20D (with
- processor Z8001,
- floppy disk 5'1/4,
- hard disk
- 160 Ko (i think 128 + 32)
- a printer
I haven't undertood if you have an identic machine or if
you found this.
I know some commands to use it, like :
- vf (volume format) with 0: or 10: (floppy or hard disk)
- vl (volume list),
- etc...
If you have some information about this computer, ...
you can say these ...
You can consult my home'page at :
http://taln.univ-avignon.fr:8080/personnel/bigi.html
Bye...
and sorry if i haven't undertand what you wanted.

Thanks for the info! Do you know if it's positive on the inside or outside?
(either + -O)- - or - -O)- + ?)
I found a web page that says you can bypass the battery by replacing the 9v
with a battery eliminator and removing both the lead acid batt and its
cover. If I can find a power supply, I'll give it a try (since I think my
battery is hosed.)
