Just ran across an interesting oddity --
I ordered a few 7475s to replace the ones with corroded legs on my
Imlac's memory control boards; upon replacement I note a dead short
between 5V and GND (as evidenced by the 5V supply being drawn down to
1.5V or so on powerup). After pulling the chip out, it's pretty clear
that pin 5 (VCC) is shorted to pin 12 (GND), as are pins 4 and 13.
Verrry odd. I grab the other replacements I ordered and they test the
same way.
My curiosity getting the better of me, I break the top off the chip (not
entirely successfully). You can see the results here:

The picture's not great, but you can see that pins 4,5,12, and 13 are
connected to asolid piece of metal! There does appear to be adie in the
chip, interestingly enough(not pictured). Defective chip? Other chip
relabeled to be a 7475? Who knows...
Unfortunately, I can't find the invoice for these items (I ordered these
a couple of months back), so I don't know where it came from; it was
probably either Jameco or Digi-Key...
Ugh, I wonder how many others of these chips I ordered are fakes...

I rescued most of a Kaypro PC a couple of days ago - a somewhat interesting
beast, being a backplane-based XT compatible. It was actually a stray ST225
drive which I saw first (and which I expect belongs with the system) before
I spotted the machine itself, although of course it wouldn't surprise me if
the drive is snafu.
I have the CPU card, along with FDC/mem/RS232/parallel card and ST506/412
controller card (plus case, PSU, backplane). What I don't have is a
keyboard, display adapter, floppy drive, or monitor.
Questions:
1) Does the machine need a specific keyboard, or will any old XT keyboard
work? (I say that like it's easy to find XT keyboards these days!)
2) I'm assuming the bus is 8-bit ISA; will an 8-bit VGA card likely work
(as I have VGA CRTs laying around)? (And does anyone know what display
adapter the machine would originally have had?)
3) Will it run plain ol' MS-DOS, or does it need something a little more
uncommon due to hardware quirks?
It's very much early days right now; I've not tested the PSU yet, who knows
what faults the boards may have (but at least they're mostly obtainable and
socketed ICs) and all of my spare floppy drives are in overseas storage, so
I'm seeing this as a long-term project, but it would be nice to eventually
return it to operational state, even if only as a floppy-only system.

Just clearing out more stuff
This is a Digi PortServer TS-16, From what I can tell its a terminal
server and itll allow you to connect your Terminals and other serial
based stuff to the internet. It has 16 ports and itll allow you to run
serial over ethernet. It has 2 Serial Dongles with it

It wouldn't be a good item on ebay unless the seller was enough of a dick to
break the system up to ensure maximum profit.
Capitalism called. Now if someone wants the system they have to fight god
who knows for the software to actually use it.
I need to rid myself of an IBM S/34, (4) 5250 terminals and a printer that
I have. I sold the house that it is stored at and closing is in 30 days.
One way or another it must go.

The documentation is spoken for, but the hardware is available to anyone
that wants to come and get it (Ohio, USA 45865). The thought of breaking it
for scrap does not appeal to me all.

Heres the unboxing photos, the original owner used it for one project
and then boxed it up and put it away, he even went as far as removing
the winchester hard drive and put it in its original box. I had to
install the drive, give it a good firm wack because of stiction and
reinit the drive, but its fully functional, The only thing I can
think of using it for right now is a VT100 terminal to my Mac like I was
doing with the Apple IIc

I think we can all agree by now that once we put something on the internet,
regardless of obligations or contracts or licensing someone else will use it
without permission and shame on you for complaining over a photograph that
he did not even hotlink. What do you want? The auction to have the infamous
"IMAGE NOT AVAILABLE" placecard so we can all at least wonder what exactly
is for sale? Generally when I see another site using my photographs (and
normally from my photobucket but that's the reason I pay for uncapped
premium four times a year) I'm proud of it because it means my photos were
decent enough to appeal to someone else. Makes no sense to photograph your
systems if you don't want people oogling over it.
Regardless, he has updated the listing with a proper photograph of HIS
system.
