1802 uno v22 === starting with oscar’s kim-uno code, i changed out the 6502 for an 1802. see: for more details. what’s new === v22: * faster execution due to oscar’s patch (set nice_value in 1802config.h) * you can create multiple non-overlapping roms (see 1802rom.h for details) * all 3 demos now in rom (idiot at 8000, etops at 9000, and hi lo at c000). configuration === you have 1k of ram at 0000 and no interrupts. there is a small rom at 8000 to set the rom you must reflash the arduino the various commands to save and read memory only operate on ram you can "load" through the rom but it won’t change the contents. there are three demo roms: * idiot/4 at location 8000 (see below) * etops monitor (see and below) at location 9000 (see below) * a hilo game is at c000 (see below). to run it put c0 xx 00 at location 0 to jump to it (where xx is 80 for for idiot/4, 90 for etops, and c0 for hi lo). on power up (but not reset) the first 3 bytes of ram initialize to c0 80 00. the file 1802rom.h only includes other files
