Ah! The LVDC had no ROM at all! Good lord. The entire program sat in RAM. Aaaaaaaaaaaa

Huh, and if you have ROM and RAM I guess it literally is a Harvard Architecture

I never thought of that before!

@natecull Not necessarily, or even typically. It is quite common to have both code and read-only data in ROM while using RAM for read/write data. RAM can also be used to hold code loaded from some type of storage that doesn't permit direct execution.

@natecull I’m going to use “bugger word” instead of checksum from now on 😁
