There are two versions of XXDP+ V2 monitors.   The XXDPSM.SYS is needed for cpu's w/o MMU's or don't have more than 28KW.  This and XXDPXM.SYS are both on the AK6DN diagnostic image. However, only a few other programs exist on the image. In SIMH the AK6DN image does the same thing.  The halt l

in the late 1960s and up thru 1979 UTexas at Arlington Computer Science initially only offered a Masters, and was housed in Industrial Engineering. If you wanted an undergrad degree in "computing" you went thru the math department and got a BA or BS in mathematics with an emphasis in computing. I t

Convergent Technologies NGEN and Datapoint monitor

Good evening, folks... Does anybody know if Datapoint made monitors for Convergent Technologies? In my "near junk" section I have some modules that someone stored in a warehouse next to a carpenter shop and under bombardment from bats and birds.  The modules were made by Convergent Technologie

XXDP on PDP-11/03

Recently, I assembled one of the RX02 emulator boards developed by AK6DN.  I am using it presently in a BA11-M box with PDP-11/2 cpu (really basic 16 bit system).  I put the disk images from github on the SD card (RT11 V5.07 and XXDP not sure what version). The box has a BDV11 bootstrap / term

I can attest to that. ;-) Where I went (CMU) the CS department grew out of the Math department…while I was there the only degree that the CS department granted was PhD. So everyone else majored in something else (EE in my case…which had a bunch of digital stuff but still focused on a lot of t

In my school in Canada, the computing science program started about 1974 and grew out of the math department, but when it was formalized as a department in 1976-77 the university wisely placed it in a new “Interdisciplinary Studies” faculty and staffed the school with people from mathematics, ch
