Ah, for some reason I'd misremembered that it was Tim. It would be interesting to hear his perspective, too.

and he'll be happy to support it in the future if there's some interest ...

That MIST board really does look rather interesting too .... 8)

Yes indeed !
I hope TeribleFire will introduce himself and start a thread, although from what he told me I don't think he'll spend a lot of time on the forum for matters not directly related to his Archie core : he seems not to be very fond of spending a lot of time browsing forums (well, I can understand that : it's not always time spent the most efficient or the most productive way).

To make a long story short, from what I understood, he'll answer questions from people interested by what he did and interested by the project, and stick to that (again it's what I understood, and I can be wrong).

Another one from the same channel, which I really loved :
https://www.youtube.com/watch?v=n9z9eDMZqCk

1st it's connected to my past job for about 15 years.
2nd to me it's an example of the great quality the BBC broadcasts are praised for versus garbage TV where journalists are the stars and ask stupid questions all the time (with despise for people who actually do something technical).

Inspired by this video ...

https://www.youtube.com/watch?v=KrTmvqwpZF8

... where Chris Curry explains his feelings (the look in his eye specifically ... I'm sure we've all had these moments in our lives) the first time he saw the IC from TI (at about 11 minutes in, but I'd recommend watching it all :wink:) calculating the approximation of Pi (22/7), I thought I'd try to re-create it today (this morning actually).

The only "Sinclair Executive Calculator" I could find on EBay was the "Memory" version. It does still look pretty cool considering it's from 1973 and I can do the calculation in one hand whilst holding my iPhone 6s in my other hand videoing it.

Here are a few pictures of the calculator and the video.

Sinclair Executive Memory 1.jpg


Sinclair Executive Memory 2.jpg


I must admit up until hearing it mentioned in the interview by Chris and subsequently Google Maps'ing the location I didn't realise there was another St Ives in the UK (apart from Cornwall).

Sinclair Executive Memory 3.jpg


https://www.youtube.com/watch?v=M8zV45k3BYQ&feature=youtu.be

It contains one of the first Microcontrollers (basically a computer on a chip) from what I can work out, which is doubly pertinent as I use Microcontrollers most days in my work and it arguably spawned both the Sinclair range of computers as well as the Acorn ones ... =D> 8)

Nice find! I posted a not-entirely-dissimilar video featuring a later calculator, the Sinclair Scientific. It uses a successor chip from TI, but while the chip was intended for a four-function calculator, Nigel Searle at Sinclair crammed a scientific calculator's firmware into the 320 words of ROM. There's a good write-up of the whole thing and a simulator too, at http://righto.com/sinclair

(You might notice I use 355/113 as my test, so much more sophisticated than 22/7... I have also been known to use 1/0.81)

Thank you, I watched the Steve Furber video earlier in this post and after it had finished up popped the link to the Chris Curry video.

As he mentioned the calculator in the interview it piqued my interest and I immediately went to EBay and found it there, a car boot find according to the seller 8)

Interesting you did a similar video :shock: although I've just heard Sophie Wilson say in one of her interviews (in this post) where she gives everybody the finger (showing the similarity between nail growth and the size of transistors these days I have now found out :lol: ) that when they produced the first ARM IC that's what they did then too, so it must be a "thing" from back in the day, calculating an approximation of Pi :idea:

One thing I liked about the calculator and wanted to show in the video is the 7 segment LEDs go "bonkers" for a split second before the result is shown :lol:

I don't suppose you have any more information on the processors in these things as there doesn't seem to be too much on t'internet about them. I had seen the Nigel Searle write up which is very interesting.

It never occurred to me that these calculators really paved the way for a lot of old computers and stuff we use these days of course 8)

These first microcontrollers are indeed remarkable! Ken writes some more about the internal architecture in his previous article at http://righto.com/ti - his initial sources were the patents, which are probably a very good primary reference, but also he indulged in some deconstruction of the actual chips, in the style of visual6502 and with the help of some people who'd gathered around that project.

I remember seeing Sophie saying that she did "PRINT PI" and thinking - that's what I do too!

Oh yeah, what about the guy who built Hitler's computers?

https://www.youtube.com/watch?v=2a6HMqsYnxk


Well I'd say that was remarkable. We could have had WIndows 10 in German and all kinds of funny alternate culture.

Don't like thinking about it!

Not interesting for the failed painter, some nice fellows from the USA already had some powerful tools to sell to make profits.

I've been collecting interesting* computer related videos for a while in a playlist. Try it for size:
Matters Computational (YouTube playlist)
Long and short, old and new, computer science, computer history, retrocomputing, some computer security, homebuilt computers and homebrew CPUs. Some of these are good for the text in the descriptions or comments and many of them will prompt some good suggestions for related videos.


Image
I still add to it from time to time. It's not in any specific order - probably new videos go on the end.

* well, interesting to me, of course.

Not really remarkable, but seems like a nice little summary of the home computer industry in the UK in the 80s.

This is what it looks like when someone plugs their synthesiser into the CUB: https://www.youtube.com/watch?v=QVmp9uUTREo


Surely that will break it. Though for an idea, can I simulate that in BASIC, somehow?

We're very lucky that people like Steve Furber and Sophie Wilson are capable, and willing, to give these sorts of interviews to interested parties. The Sophie Wilson interview is also very entertaining, but I do wish the interviewer would use a tripod and skim a few Wiki pages to prepare first ...

Did anyone post the MAKING OF ELITE, with Peter Snow?

Why Snow? I know they gave him the best computers on election night, though.
