Cool! My first real world program was an assembler for the 8080/Z80 instruction set. I had to write the OS first, of course, in order to load the assembler from a paper tape reader and punch the tape in the first place. That was all done with toggle switches until I got the punched tape unit working. ASR33, alack, I knew you well! What fun days of discovery we have lived, Mike. I wonder what today's kids will see? Doubtless, you and I won't understand much of it, even if we try.

How many transistors in the same area? Density?

I was reading about the history of the DEC Alpha chip yesterday. Most of the transistors are for the cache, not directly related to processing.

All the years I worked with DEC computers never got to work with an Alpha, mostly PDP and uVAX.

HP killed the OpenVMS Hobbyist program again, so I don't have licenses for my systems now. And the power supply for one of my AlphaServers has gone flooey.
There is now an X86 version of OpenVMS, but apparently it only works as a VM.

Yeah that's a bummer.
I see a lot of uVAX's on ebay, not real cheap but wouldn't be able to afford the licensing anyway.
Sides don't know what I'd do with it, it's been MANY moons since I last worked on one!

Yeah, I last worked with OpenVMS in 2002. I bought my systems as a way to keep from getting rusty. The hobbyist program was a real boon. I don't think there's much probability that I'll work with it again at this point. I don't know COBOL  .
Getting viable disks for the MicroVAX 3100 was a challenge.

Aside to aside:
My book on GPUs and parallell programming mentions that one reason why these GPUs manage to fit so many processing units on one die is that they process so huge amounts of data, often in streaming fashion, that you see far less locality than in standard run-off-the-mill applications. You keep the values in registers while you still use them actively - that is not for very long. When you throw them out of of the registers, you never see them again. So a cache wouldn't be of that much help. Possibly for a few control variables (and GPUs frequently have a small cache, often common to all the processing units), but not for the heavy data flow.
With (almost) no cache, you have lost of real estate for building arrays of processing units.
Aside to aside to Aside:
I am not going to identify that GPU book. It it so bad, in some areas grotesquely bad, that I don't want to point anyone else to it.

Correction: On this day, 52 years ago.
Of course I realize it was implied.
So I asked ChatGPT:
"if I say "on this day", do you assume I mean "today", or on this day, but a different year?"
Its response:
"If you say “on this day”, I would assume that you are referring to the same day, but a different year. If you want to refer to today, you can use the phrase “today” instead."
...to which I say: Damn. You win.

Greetings from a long-time lurker.
A few months ago I tried posting a link to a video I thought this community would enjoy. It's a short interview with Steve Wozniak recorded 40 years ago when the Apple II was near its peak of popularity. I wrote a brief description and history, and included a link to the clip in my personal Vimeo account.
My message was immediately "flagged as potential spam." Although it was "awaiting moderation" it never surfaced. I tried twice.
IAC, I'd like to try again to send the link. I was told that Woz himself saw the clip a couple of days ago and that it cheered him up following his stroke in Mexico last week.
Can anyone tell me if I somehow violated some CP code of conduct? Should I give it another shot?
Thanks-
-David
