Not for the 6502, but possibly interesting to the other Forthwrights here: Foud a link on Reddit (where there is a forum for Forth) to a "Forth on a DIP" project (
http://jeelabs.org/2015/07/22/forth-on-a-dip/). This uses the LPC1114 chip, a 28-pin DIP ARM (
http://www.nxp.com/products/microcontro ... 4FN28.html), with Mecrisp Forth (
http://mecrisp.sourceforge.net/). The author has a moment of insight:
Quote:
Forth code runs surprisingly fast. Here is a delay loop which does nothing:
: delay 0 do loop ; ok.
And this code:
10000000 delay ok.
… takes about 3.5 seconds before printing out the final “ok.” prompt. That’s some 3 million iterations per second. Not too shabby, if you consider that the LPC1114 runs at 12 MHz!
Well, duh.
