Several things Sinclair was made fun of back in the day are now "the work of geniuses". Among them is wafer scale electronics. Sinclair's: http://www.computinghistory.org.uk/det/3043/Anamartic-Wafer-

It is interesting to watch the video of the actual interview that they recreate in the movie. The movie Sinclair seems a bit upset while the real life one was smiling a lot and being very friendly.

Many theories were developed after the practical implementations. It is really hard to separate the two. Relational databases, for example, is a case where the theory came first. But would have that been created without the experience of us

Any computer (with enough resources) can simulate any other computer. So if you have Lisp by running such a simulation (interpreter) on your PC it is not the same thing as a direct implementation of lambda calculus. The famous Lisp Machines

I think Wilkes got his award for his software contributions despite being well known for his hardware efforts. The 2009 award to Chuck Thacker, on the other hand, was clearly based on his contributions to hardware. I have the impression tha

I always mention the Rekursiv in my talk about Smalltalk computers. Its problem was being a CISC in the era of RISC. The Manchester Mushroom from just a little later had initially the same problem but went through a major redesign when they

The 6502 will be 50 in 2025, so unless they stop making them between now and then we will have at least one example of a processor lasting that long commercially. If not, then the Z80 will be 50 in the following year.

Some people are very picky and only accept Smalltalk-80 as "Smalltalk". Of course, that would make Smalltalk-72, -74, -76 and even -78 not Smalltalk, which would be very odd. I, on the other hand, consider Self and Slate to be goo

The first Actor languages were inspired by Smalltalk-72 and make a lot more sense if you are familiar with -72 and less for those who only know Smalltalk-80.

There have been FPGAs in the past which used the logic blocks for routing, including the Xilinx 6200. I think that was also the case for the Atmel AT40K FPGAs, but could be remembering wrong. In fact, our project for the previous Google shu
