Amazingly detailed 1hr talk about the Apollo Guidance Computer. It's
stunning how much they got into mid-1960s technology: 1 MHz hand-made
processor, 1 k of RAM, 4 k of ROM, and bank-switching, with a
fault-tolerant multitasking OS with an interpreted metalanguage.
Absolutely stunning.

Yes. But it's actually 12 k of ROM if I remember right, and that was expanded further
later on.
Another nice example of a large program on a small computer is the original ALGOL
compiler, written by Dijkstra and Zonneveld in 1961, in about 6 months. It implements the
full language -- not a subset -- on a 4k machine.
Gauthier van den Hove wrote a Ph.D. thesis about it, I believe that will be published
soon. Very nice work.

Well, yes. I was oversimplifying things a little by talking about the
base, un-bank-switched space. (I copied-and-pasted a FB "Vintage
Computer Club post I made.)
And it's kW not kB of course.

Well, this was one of the VERY first computers built with
monolithic integrated circuits.
NASA sure assigned a TOUGH task to the designers!
Another one was the Honeywell Alert, designed for the X-15
project.

Liam, thanks for posting this. What a wonderful way to waste an hour. ; )
I can also highly recommend the book 'Digital Apollo', which goes into some detail
about the man-machine interface of the AGC and the internal debate at the time of the role
of man as "spacecraft pilot". -C

Haven't watched this video yet but am keen to do so as "ultimate" is a bold
claim to make.
For my birthday recently I received 'SUNBURST AND LUMINARY: an Apollo Memoir' by
Don Eyles.
http://www.sunburstandluminary.com/SLhome.html
I've only read a few chapters so far but it is a fascinating new (2018) account of how
the AGC
software came about, and his part in it such as writing the P63 and P64 programs for the
powered
descent to the lunar surface.
I've not got the Digital Apollo nor any other books on the AGC but if I had my
druthers I would
wish to get the one by Eldon Hall, however it is a rather unusually expensive paperback so
that
will have to wait.
Steve.

This an outstanding presentation. The bold claim is actually somewhat justified...

I am very glad to hear that.
The comparison that sprang to mind, actually, was your wonderful
series of Alto restoration videos, which I have been evangelising to
people just recently.

I worked with Michael when we were both at Apple (a really good/smart guy). At the time
he was focused on 6502 related stuff and we had many discussions about old hardware.

I watched the whole thing but skipped the more typical instruction
explanations. Absolutely mind-blowing, hats off to you!

All of my knowledge of the 6502 comes from my time with the Commodore
64, where I learned about the 6510. As far as I understand, the 6502 is
still used regularly.
Have you got any interesting examples of where the 6502 is used in
contemporary work or new projects? Thanks!!
Kind regards,
Andrew

Western Design Center, who designed and manufacture the WDC65C02S and

I think they are focusing their units for IoT products in design wins.
