Hello all,
Another item I keep forgetting about is a digital MINC-11. This appears
to be a data acquisition system of some sort. The MINC chassis contains
only a clock card and an AD card. The chassis is on a cart that also
contains a digital RX02 dual 8" floppy drive enclosure.
The most curious thing is that there is a label stuck to the front
warning that the unit "220VAC/50Hz only". I don't know if this is the
only voltage it will run at, or if it is simply set for this voltage. I
don't believe we ever used this equipment. I think we acquired it when
we purchased some other surplus equipment back in the 1980s.
Can anyone use this thing?
Later,
Jon

I'd be interested...esp, in the AD card, and the RX02 as well. Do you
know what the AD card is, and whether or not its Q-bus?

Jerome Fine replies:
The MINC-11 was a box used to provide easy access to a Qbus backplane.
Normally, data acquisition was done with the system, as you suspect. It was
an 18 bit backplane with a number of Qbus slots at one side which held
an 11/23 CPU (usually the dual version M8186), memory, DLV11-J,
and a controller or two. The RX02 controller was normally standard
and the RL01/RL02 controller was also popular. An RXDX1 or RQDX2
could be added as well, but there hardware needed to be adapted to either
the RX50 or the hard drive.
In between the boards mentioned and the BDV11 on the other side was a
number of Qbus slots to hold data acquisition boards. This was a 1979 to
1980 item - I think that would be the time frame. Since the BDV11 boot
roms could not handle an 11/73 (odd address trap), that CPU could not
easily be substituted.
The most curious thing is that there is a label stuck
to the front
warning that the unit "220VAC/50Hz only". I don't know if this is the
only voltage it will run at, or if it is simply set for this voltage. I

Probably JUST the setting in the power supply.
Can anyone use this thing?
If you were closer, I would take the RX02 drive.

Nice box...

The floppies (IIRC) had different pulleys based on the power frequency.
I don't believe conversion was difficult.
Anyone else sure on the above.

Hello again,
> Another item I keep forgetting about is a digital
MINC-11.
I actually had time to go check this box out and here is what I found.
It is set up like Tony and Jerome said. Here are the cards in the MINC:
M8012-YA Q-BUS TERMINATOR
MNCAD A/D converter
MNCKW Clock
M8043 DEC DLV11-J Four-Line Asynchronous Serial Interface
M8659 VT71 BUS GRANT BRD
M8659 VT71 BUS GRANT BRD
M7954 INTERFACE LSI11 BUS TO INST.
M8029 RXV21, Q-BUS RX02 INTERFACE
M8044DB MSV11-Dx (M8044-Dx) 4KW-32KW w/o parity
M7270 DEC KD11-HA LSI-11/2 CPU
I checked the voltage stuff. The MINC has a switch with a flip plate for
120V. No problem there. The RX02 does not have any provision for
switching voltages/frequency as Tony points out. This makes me wonder
even more about how this thing made it to Madison WI. We may never know.
:)
Anybody want to pay shipping to a country where the RX02 drives could be
used? :O
Thanks for the info.
Later,
Jon
