I'll try the other addresses. When I tried <G=C800:5>, the light on the HD
(Seagate ST-506 5 MB) came on for about 10 seconds, the screen went blank,
and the computer rebooted. I'll see if the other addresses will work.

Adaptec is of no help that I could find. They only have stuff on the new
boards.

Option swap really used to fry me.

Severely underrated. A 50V cap running at 70! The diode was a victim.
A remember a box of returned cards the size of a large chest refrigerator
at WJO01 in '84. I happen to look at it and after the third or forth card
surmized the failure... annoyed a few people that I could see that without
a full field study. Oh, the cause was a transmission error, the person
that drew up the BOM copied the wrong values. It would go years that way
before someone becuse of the problem would pull the original DD, CS, KPL
and see they didn't match. Classic case of why CADD was a desireable
thing.

Hi! I have an old Adaptec Hd controller that I'm trying to use in an IBM
PC (5150). Here's what it says on it:
adaptec, inc.
ASSY401406-00
REV K
I'm trying to find out how to get into the controller's BIOS so that I can
set up the HD (using DEBUG). There's two jumper blocks, and one single
jumper. I'm going to post a picture at:
<http://members.tripod.com/general_1/adaptec.jpg>
I'll try to get it posted in about 20 minutes.
ThAnX,

If anyone might have the PC support PC install disk for an
IBM System 36, I can't find the one that we should have.
Should have link36.bat startrtr endrtr files on it.
I have the book, I have the install files for the 36 but not
for the pc's. Have to convert 5 or 6 years of data!
Thanks for any help!

Same with me (but I laught a lot about the PII vs. PPC spot :).
Especialy this Think Different is a horror thing. And they
eventualy couldn't hold up their own arrogat idea of presenting
wordlewide unifying 'good' people, so, where is the idea ?

Yeah, but it taught you to think microcode, block diagram and
real troubleshooting instead of pul and swap.
I was a board swapper in the Field, but it made me an informed and
logical board swapper.

Sure. Tell the customer he/she will be down an extra hour while
you extend the board to find the fault, desolder the chip
and replace the 10 cent bus driver. Nope. Swapping was reality in the field
when I was there. Board level (early 80's DEC) was (unfortunately)
replaced with shotgunning and option swap out by many in the late 80's.

They were used in the 11/70 class, the RK05 maint class and a couple of
others. The 11 new hire used the 11/34's built in programmer panel
for much the same stuff.

Sure. Had one of those guys at Naval Air Propultion in Trenton, NJ.
Customer: "The te16 won't go on line. U134 should go low, but it's floating.
Can you bring us a driver chip."
Field Service: "We don't have it in stock, but I'll get one in the next
three weeks if I P1 it... Or I could come down and change the LAW board
on the drive (LAW -- TE16 Logic and Write board) in about 15 minutes."
And then there was the site that complained about failing RK07 Dual port
diags on 11/70's when the drives ran flawlessly unde RSX11 and IAS.
The problem was race conditions in the diag. The diag was no longer being
updated. The only fix that got the field service folk off the site
was noop'ing the error calls on the tests with the race condition.

Absolutely. That's a very common failure along with the diode and cap
on the VT100 video cards that's underrated.
