I have that one. Not similar enough. What I'm chasing is a huge asymetry
in the amp and so far no bad transistors. Back when I had the cousin to
this
one and had a similar problem. I also need to see the layout so I can find
why one half the amp is not reacting to it's mirror.

I'm looking for schematic on a heath 10D-203-31, 5mhz trigged sweep scope.
I'm chasing a vertical amp problem and schematics would help identify the
heath house numbered transistors.

Hello, all:
I'm looking to transfer some files from my PC to my //gs. I could do it wit
h a null-modem cable (for which I need the 8-pin DIN to DE9 pinout). I could
also do it with a Superdrive connected to the //gs. Anyone have any experien
ce with an external Superdrive? What do I need on the gs side? I have a ROM0
3 gs with System 6.0.8.

And I can see from the second picture that you have (very sensibly)
assigned it to guard your most precious possession: the wine cellar.
Cheers,

Yep, I was lucky enough to be able to use the disk drives (I thnk there
were total of three units) in our school iun 1981/2, back then the
drives (Commodore 4040s), cost about $1200 ea. Most everyone else were
at the mercy of sometimes flakey tape decks.

The school did that for a while after the Apples came in.
Ever see the movie Sixteen Candles, the nerds in the movie make a bet
for a box of disks and quote a $50 price, that was for 5.25" disks...
Now things are going back up for 5.25" (DS/DD) disks as the sources are
starting to dry up, I load up on boxes of them when the dollarish stores
get shipments of them.
Hint, you can spot a 5.25" diskette because it usually has a hub ring,
this was partly so apple Disk ][ drives can grip it, there was at time
hub ring kits for that purpose as well as the keep the old drives from
bending the diskette's hole. HD disks generally do not.

Nope, SCSI to the rescue. I use MCS 700 future domain in my 70
bought used from C.R. when I was in US visiting my friend.
Actually a cheaper way... Parallel port adaptor. It's how I run Win3.1 on
that
one without loading the disk that on it (currently only dos on it).
Should work in your 50z but needs 386 level to work according
to DB Young and shove in more ram while you are at it.
True. The problem with that machine is common to most 286s, there's
enough perfomance to make use of it but, not enough ram, disk and it's
not 386.
So in the end I can easily run dos/lanman/IP with windows 3.1 but, only
dos apps will fit in the available ram.
I have an INboard386 PC in a leading edge. Same problem more or
less. I do have a 386/16 with that and 1meg of ram but 4-5mb is needed
to run windows apps of any value. I plan to try minix in that beast as it
would leave enough uesful ram for a IP stack.

There's mine... I haven't had the time to do anything with it
recently, but I have a fair number of instructions working. PI
doesn't work yet, and the only devices which sortof work are
the CTY, CLK, PTR and PTP. I've got some -10 code which it
executes built into the program so I can test instruction
speed... about 500k eips (emulated instructions per second) on
a 6x86...
I'm basing mine on Bob Supnik's simulation control package, which is
really nice in itself.
