Default Re: Recreating the Bywood Scrumpi

The Digirule is indeed a PIC but, and it does use its own made up instruction set for an imaginary 8 bit uP that is implemented on it - but, as it has a programming interface I was thinking of knocking up some firmware to convert it to an SC/MP! If you look at the picture of the back of the rule on the site they are listed there on the site https://bradsprojects.com/digirule2/

Did you know that the System 1 used 8154 and 571 chips because they were on the MK14 and "around" you can see the interview with Sophie Wilson here:

This also has the snippet in the table that the MK14 was the architect of its own doom as it was used with its programmer to blow the first PROM's!
