An Atari 800 - 1.7mhz 6502 computer infering a neuronet.

[BrianHG]

Yes, someone wrote in basic for an Atari 800 (he says 800XL, but in 1979, it was a regular Atari 800).  Though the neural net was trained on a modern 64bit computer, it is the Atari 800 running in Atari Basic doing the inferring, meaning running or playing back, the neural net.

It appears to be a simple OCR (optical character recognition) net which looks at a low res single character B&W image, then reports back the 'number' which it has decoded from the bitmap.

It is slow, but functional.  If it were written in 6502 assembly, it probably would have run at least 25x to 100x faster as Atari Basic was not a compiled language, but an interpreted language which ran from the source code listing.
