I take it that I can notify the owner that these systems are of no interest
to anyone here. I cant take them, too much and too big.

I need someone to make a hi-res scan of a single sheet of 8.5x11 fanfold
paper with the perforated side holes still attached. I'm making a graphic
image for a web page background, but without having a sheet handy, it's hard
to gauge the proportions of where the holes should be. Oh, and I need it
five minutes ago. :)
Thanks!

Can't you sleve it as is done with the power switch on an AT power
supply?

Or an abandoned biscuit factory :)
Norm Aleks and my 4331 system is at the Sunshine Biscuit Factory in
Oakland, CA, in a room that used to be used to store Cheeze-Its
dough.

Hi Chuck
I'm not sure, not being an expert, but your problem
sounds like an issue of the flux not holding up to the
temperature.
You should check with the manufacture of the solder
to find what they recommend. Also, sometimes welding
supplies will have some info as well.
If the flux burns off too soon, it won't do any
good. The instant the surface oxides, the solder stops
flowing.

Hi
For these things, it really depends on the flux used. You need
to be using a higher temperature flux.

I think this listing may be of interest to collectors of old IBM stuff.
I don't think
the seller has the slightest idea what the fiche document, and they
copied the
term "System 3" into the listing like they were clueless. Any system 3
people
may want to pounce.

Yes, working your way through the schematics, actually measuring the
signals, makes you "learn" how something works - in detail!
I know a little more about the M7859 11/34 console than I did, say
2 months ago ...

Hello all,
Regarding the recent talk about using hard drive carriers (in order to
reduce the number of machines in your environment, etc.), has me wanting to
invest in a few.
Is there a specific brand anyone uses?
I have one drive carrier I purchased years ago (at a local mom & pop
computer store for something like $15) -- a cheap, no-name brand (can't
even find a brand name on it). The drive connector in the tray is flimsy,
it is a pain in the a** to get the drive in and out of the tray, and it
just generally doesn't give me a real cozy feeling of sturdiness when using it.
So I ask, are there specific brands of these carriers people use? Where do
y'all purchase them?
Regards,
-Eric
I was playing blackjack (BASIC program) on SIMH with my OS/8 RL02 image. I noticed that every time I played the game the cards drawn were identical, both by the dealer and myself! A loop to print RND(0) ten times always shows the same ten numbers... doesn't sound very random to me :)
Is this an artifact of SIMH, or BASIC? (Will it go away when I run the program on the real 8/A)?
thanks
Charles
