System Source has a bunch of old Macs that belonged to me. Back in late 2008, I was dissolving my household in Baltimore in preparation to move abroad. I couldn’t take my collection of vintage Macs (which, at that time, had not skyrocketed in value as they have in the past few years), and so put up a Craigslist ad listing them all as “free to good home”. Nary a day later, Bob Roswell himself emailed me, asking if he could have them for his “small computer museum”, offering to come pick it all up the same day. And he did, taking not only around a dozen Macs, but also a LaserWriter II, various other accessories, and nearly a whole decade of various Mac magazines. I could not have been more delighted at the outcome. It would have broken my heart to see those things end up in a dumpster, and instead it went to someone who loves old tech even more than I do, with the possibility of it being on display for others to enjoy, too. So if you see a Mac IIci or Quadra 950 at the museum, there’s a good chance it used to be mine! (Also, in talking to Bob, it turned out I already knew his wife, who had worked at a college I had attended! They don’t call it “Smalltimore” for nothing! :) ) I really need to pay the museum a visit the next time I’m back in the area, I’ve actually never been!

Back at the Uni I was lucky enough to have seen a, non functioning, "Univac 120". The 490 you are showing looks just like the same machine, with the tubes replaced by transistors. In the 120, the tube sockets had very long legs, almost like 2 sockets connected by piano wires. It formed something like a cage were they soldered the resistors and capacitors needed for the polarization of the tubes. Then the whole assembly pluged in a backplane in almost the same fashion of those transistor cards in the 490. BTW the front panel of the 490 is way more modern than the one of the 120, that still had a rotary phone dialer as an input device.

I think that you shot with the space bar. You walked right by an Apple Lisa, sitting next to the Alto. The Lisa OS borrowed much, both visually and conceptually from the "Desktop Metaphor" designed into the Xerox Alto when running its Window Manager. Notice the Portrait-sized video terminal that is taller than wide, designed to look like a sheet of paper. We all went mad for the Desktop Metaphor in the 1970's and 1980's. Unfortunately, Lisa had fundamental flaws, and buyers thought she cost too much. Lisa didn't sell. Apple's management bet the farm on Lisa's successor, the Macintosh, and came up with a legend. Some people are just born lucky.

In the IMSAI system, the memory you are dumping is not the boot ROM. It is the video RAM that contains the ASCII codes for what is actually on the screen. So when you first issue a dump command it shows you the startup message that is still on the screen, but also the command that you entered. When you press enter to scroll it you see that it starts displaying the earlier output of the dump command.

I could not believe my eyes as this video started. That Bendix G15........O M G that partially answered a question I've had for over 40 years.. Those modules with their anodised colour coded handles and the board wired up to the tubes. As a young child interested in electronics I got a box of those modules to tinker around with probably about 45 years ago. I never knew their origin and like so much what we would now call E-waste, I slowly cannibalised them over the years for components. But I never knew their origins and always was impressed by the logical design process. Now I'll have to go dig into the deepest recesses of my archives to see if any have survived all these years. Fantastic to see that something like that was here in Australia so many years ago.

The lack of FCC certification is however not why the HP sings. Technically all computers do produce noise on all their ports, but usually there is effort to filter it away. In the world of prototypes however, reducing electrical noise isn't always a big priority in computing systems. And to be honest, a lot of these old computers are quite noisy from an electrical standpoint. That Univac system's mess of wires is though quite impressive. I wonder if they had any form of "standard" for their backplane connectors at all. I at least would have power and ground be consistent for all cards, perhaps also make dedicated pins for in and out, such that accidental card swaps don't lead to card failures. (totem pole outputs don't like to be in parallel. However, transistors were expensive back then, so perhaps they just used pull up resistors instead.) Also surprised how tiny those Univac boards are. screen printing weren't a new invention back then, same for detailed etching. So it does feel like they could have made the boards larger and slightly more feature rich. However, even the part density on those boards is quite unimpressive. But I guess that they somewhat standardized the types of board into a selection of simple functions that they could then build from.
