Interested in UNIVAC 9000 Series (and IBM 360)

Some may recall the Nova 3 front panel discussion some months back. I bought a Nova 3 front panel just for the heck of it, and we discussed replacing lamp, and have the correct lamp info now. Nova 3 CPU, 2 16K boards, Basic I/O and Anyway the Nova 3 karma system was watching and guess what. http://jimsoldtoys.blogspot.com/2016/11/data-general-nova-3.html So now I may really be doing work on the lamps on both my system and on the spare front panel. Maybe the Star Trek gods are doing this, since we have a DG copy of Star Trek too. Getting scary. thanks Jim

Archiving Fortune 32:16 bits

by aek＠bitsavers.org

spent way too much time on this the past few days I dug up everything I had on the system, took pictures and dumped firmware and floppies Maybe someone will figure out how to remove the serialization some day bitsavers.org/pdf/fortuneSystems floppy images under bits/ I also started reverse-engineering the board, mostly to see how the mmu worked. Pretty basic, four base/bound sets made up of two 12 bit registers in three bytes the 12 bit adder is applied to A10-21 This all looked familiar, esp the bus pinouts. I think I had docs at one point for expansion board developers. Have no idea what happened to that.

Rogue: Mctesq was here

by rlloken＠telus.net

So I am 35 days from retirement and I have been cleaning up the office and my Redhat Linux workstation and in /usr/local/src I found: linuxrogue-0.3.7-roguecentral.tar So I exploded the tar ball and compiled it and it crashed so I carted it over to one of our Tru64 Unix Alpha boxes, took the 'g' off "gcc" in the makefile, used sed to change ncurses to curses where ever it could be found and compiled it. AND IT WORKS SWELL! Rogue is as addictive today as it was in 1982 on the VAX-11/780 running 4.2bsd. I think I will port it to OpenVMS and run it on my AS4100. -- Richard Loken VE6BSV, Systems Programmer - VMS : "...underneath those Athabasca University : tuques we wear, our Athabasca, Alberta Canada : heads are naked!" ** rlloken at telus.net ** : - Arthur Black

When I was working at IBM Bermuda (as sort of an intern), they used a 360/20 as their main service bureau machine. (I'm pretty sure it was a /20, and not a /30.) It had a card reader/punch, 4 (IIRC) tape drives, and a 1403 printer. They had just gotten in a System/3, to replace it, but only one client had transitioned to using it. Noel

Double Buffer RK11-C

I've added a module chart for the double-buffered variant here: http://gunkies.org/wiki/RK11-C_disk_controller I'm working on the prints now. (Any idea what I should call this thing? There's already an "RK11-C_Engineering_Drawings".) Noel
