O.K. I think I'll try Minix, but where can I get it?? I can't seem to find
it on the web anywhere (using WebCrawler). Does anyone have a copy that
they could email, or a website to go to to download it?

my june94 ref guide suggests this is a 30meg hard drive for an IBM AT. FRU
8286216. not worth much, but fascinating to take apart!

I don't know if this fits the 10-year-old rule (I doubt it), but
my brother has an Epson ActionNote 4SLC2/50 and for Christmas I'd
like to upgrade the measly 100+ Mb system disk he has with something
a little larger (approx 300 Mb). I'm sure it probably has the
528 Mb limit, but that's okay, I don't have a disk that large
(in 2.5" form factor) to give him.
Anyway, I wanted to know if anyone has information on this notebook
and can tell me if it can accept larger disks. Does it have the
capability of SETUP and setting disk parameters (if the disk itself
doesn't match one of the type 1-47 disks)?
Rather than clutter the list with off-topic PC stuff, please
respond to me directly.
Thanks in advance for all the help...

How about minix 2.0. It run on 8088 and fits in small disks.
Likely the caldara openlinux can be trimmed of you eliminate the source
files. The problem is not fitting it on the disk but will you have useable
disk left? Finding a 40mb disk for that laptop would be a good idea.

Ok, I may be a little slow and everyone else on the list has been to these
pages...
The first is about retro-computing on digital.com's main site:
http://www.digital.com/info/DTJN02/DTJN02HM.HTM
The second isn't so nicely packaged, it's just a loose set of documents
that are (I assume) intended just for this facility. I personally found
some interesting stuff by hunting through the trees, but then I am like an
empty vessel when it comes to these systems. But neat documents, like the
RSX-11M System Generation Guide...
http://www-ols.fnal.gov/ols/documents/docpn.html
If anyone hunting through the latter site finds anything of real interest,
I'd love to hear about it...

Somewhere in my collection is a set of ASR-33 technical

start searching to see if I can find them...
On another note, I came across my pdp-8/i maintenance
manuals (vol.1 and Vol.2) the other day...

If I remember correctly, this is exactly how the hackers at Stanford
got the DECsystem-10 to play music, but toggling the low-order bits
of the AC (Bits 30-35) and driving a speaker. This gave them 6
'voices'. Someone developed a music compiler and there was a lot
of music entered by various people...
My favorite was 'Bumble Boogie'.
About 15 or so years ago, a friend of mine wrote a compiler for the
same music files in -11 macro, and I (knowing a little more music
than he) entered a number of pieces. I entered some like Beethoven's
Moonlight Sonata and Joplin's Crush Collision Rag.
I wish I could find that compiler again... I still have LOTS of
the music files.

A screwdriver (insulated handle!) blade touched to the top cap of the
1S2 would produce a healthy arc when held somewhere near chassis
if the line/eht stage was running. This practice did not survive the
transition
to solid state devices that disliked the spikes etc it could cause!

Several non-electrically minded customers of mine now have 1st hand
knowledge
of the effects of this. 1 particular Guy had no less than 8 speakers wired
in a series/parallel MESS
(whether a speaker was series or parallel was determined by it's physical
location in relation
to the audio leads he had running all over the house) Actual impedance was
around 1 ohm on
the left channel and about 2 on the right. Result: 1 very dead STK chip
output amp.
Amazingly, it actually worked for about an hour before expiring.
Seems he had done something similar in the past (old fella) with valve based
stuff, and aside
>from a little(?) distortion it worked. I guess that proves that valves
have their advantages.
I suspect the Speaker Transformer on the valve amp could have been used to
boil water though.

Power is divided to the speakers, as a function of power formula's for
series/parallel circuits. The amplifier also has a resultant load. These
considerations can be important for the amp ratings, as well as the speaker
ratings and sound level matching.
