The V1.0 ROM's have 2 single row connectors on the
longside of the print
one up one under.
Checked today, and the floppymotor keeps on running...
Pictures are made and on it's way to you.

I'll make some pictures one of the next days, and mail them to you.
How big is your mailbox ;-)
No, please don't sent them here. I am on a slow dial-up connection, and I
have a text-only display anyway...
If you want to send me pictures, please send them to

I have quite a bit of space there.
But as I recall, there are two rows of
My V5.0 modules have a 2-row connector mounted vertically at each end
(narrow side) of the PCB.
I'm not sure but ypu 'll see when I made
I've another Integral on its way (seapost) from downunder, bought it
it has the basic rom and serialcard.
Nice. I bought a second Integral earlier in the year to get a serial
board... It camew with a couple of HPIB drives, including a version of
the 9123 I'd never seen before (using the half-helght 34 pin drives, like
the one in a 9114B), etc.
I've been looking at my Itegral today, and noticed something rather odd.
After booting, it turns on the floppy drive motor and keeps it running.
At first I thought it was a hardware problem with the drive, but a quick
check showed that the MotorOn line on the disk interface connector was
being asserted. My ohter Integral (also V5.0 ROMs) does the same thing,
so I'd be suprised if it was a hardware fault in both machines
There's a litte switch on the disk drive PCB at the front edge (not the
drive select switch at the back near the interface connector). As
supplied it was in position 'A', which means the motor runs all the time
if MotorOn is asserted. Flipping it to 'B' means the motor onl;y runs if
there's a disk in (and MotorOn is asserted). It seesm to work correctly
when set like that, but it's not how HP supplied it.
Other Integral owners : Do you floppy drives run all the time? How is
that swithc set?. What version ROMs do you have?
