Pontus.
The Corestore has two PDP-12's as well.

LCM has 2.
That bumps the number up to 15, by my count (with the RI correction by
Will).

New subject: Was: eBay PDP-12 is: DEC MINC-11
Hello all,
I'm considering to sell a DEC MINC-11, the last type of laboratory DEC-system within
the evolution from MINC -> LINC-8 -> PDP-12 -> MINC-11.
An appropriate dual RX02 within a separare housing is available also.
Before putting this item on ebay I'd like to offer the system to members of this
list.
If interested, please contact me off-list.
Please be aware, that I'm located in Germany! As an example shipment of the MINC is
estimated to approx EUR 100.

There is also the MINC-23, which I think is essentially the same as
MINC-11 but with an M8186 KDF11 11/23 CPU instead. I have one of
those. Has anyone done anything interesting with one of these? I
haven't really done anything with the one I have. Could you do
something interesting such as driving an X-Y scope with the D/A

It is. It may also have had more RAM as standard, I forget. A MINC-11
could be field-upgraded to a MINC-23 AFAIK.
The MICN-11 is essentally a Qbus machine. The MINC I/O modules use the CD
interconnect to carriy thingsl ike the analogue signal from the
multiplexer to the ADC, or the triger from the clock to the ADC. The
backplane is mechanically odd, wit ht slots further apart than you'd
expect, but electirclaly normal.
I have a couple of MINC-11s (the twin RL01 version) and a MINC-23 (RX02
version). I think the only MINC module I don't have is the analogue mux.
I have the thermocouple input, preamp, ADC, DAC, Digital in, Digital out,
and clock.
those. Has anyone done anything interesting with one
of these? I
Not too much yet. I did pull the CPU board and RAM from one of mine and
plugged in a DW11-B so I could hang it off a Unibus machine. That works
well. I must play with it all again.
haven't really done anything with the one I have.
Could you do
something interesting such as driving an X-Y scope with the D/A
channels?
Yes. The only problem woudl be that the DACs are driven by software,
unless you keep writing valuse ot them the outputs will not change. So to
get a pattern on the XY display you'd have ot keep on writing vlaues ot
hte DACs. Of course if you have a storage display you could just write
once nad let the display store the image.
From what I recall there were (at least) two software
ssytems for the
MINC-11 hardware. One was a livrary of subroutines for RT11 that
you
could link in to your Fortran progrmas. The other wa a stnad-alone BASIC
with a lot of extra routines ot handle the mINIC-11 hardware. There were
routines ot produce a pulse-height histogram of the signal on an ADC
channel, thingsl ike that. There may well ahve been an XY display
routine.

In college, we had a PDP-11/20 with DACs and an RC11 disk. So I did an X/Y display that
uses the disk as refresh memory. This uses the ?inhibit address increment? feature in the
older disk drive DMA controllers, so you can set up a DMA for the whole refresh buffer,
with all words transferred to the same address, i.e., the DAC data buffer address.
