Thanks. I'm in Ohio, 44857
As I understand it, you have a complete system, with a (fuzzy?) monitor? Is
there a HDD, or is that the bernoulli? Is there software?
Thanks,

Can anyone point me to an on-line reference showing the necessary
voltages for programming various EPROMs? I'm especially interested
in the oldies-but-goodies: 2708, 2716, 2732, and 2764's. In
particular, it seems some of them want 25v while others want only
21v, and I suspect that even the same chip number from different
manufacturers may want different voltages.
Thanks,
Bill.

One problem with that is that the average centronics connector is wider
(thicker?) than the standard PC slot allows for. I believe this may be
true of Mac slots as well.

Those of you who have been dreaming of your own Kennedy 9400, take a

I have a Kennedy 9400 drive here (Gloucester, MA) for the taking. This
is a tri-density upright unit with formatted Pertec interface. It worked
the last time I used it, but, as I look at it now, it appears that the
backup
battery on the CPU board has failed. It would likely be necessary to run
through the calibration procedure after replacing the battery. (I recall
doing the calibration before, so it must be in the manual. These drives
have an RS232 port to control the diagnostics.) I also have an extra
drive
(with mechanical problems) for spare parts; they should probably go
together.

25 and 30 are ISA, anyway.

K&E made a bamboo one, too. (At least mine looks like bamboo -- it
certainly isn't mahogany).
I was told that bamboo has a low coefficient of linear expansion, which is
why they used it.

It is -- vary well done! There are still people interested in them...I
didn't know there were so many slipsticks around!
(btw, I bought about 10 at an auction awhile back...still have a few left,
sans cursors. Anyone want one?)

First of all, did MS Xenix run on PC hardware?
Secondly, was there ever a Windows NT 1.0 and 2.0? How did they compare
to a cheap version of UNIX?

It is interesting that many of the error messages in the pre V3.1 beta releases
referred to OS/2. Maybe it was an almost clean room.
