22 years ago, I made my first board, this NES cartridge. With features like an 8-bit MCU used a coprocessor (a new model at the time), writable flash memory, RS232 interface, mod-free audio expansion (using audio IRQ to write $4011) with my own lo-fi audio synth in software.
ALT printed circuit board, through-hole socketed components

This PIC18F4620 runs >5 instructions for every NES CPU cycle. It has an 8x8 multiplier, which the synth uses. It's not as fast as an SNES Pilotwings DSP, or an RP2350. But it can Do Some Stuff anyways. This is matrix multiplication for 64 objects. NES vs PIC18 accelerated.
Z80 to 6502 JIT compiler seen in operation, emulating Pacman on NES at the mind-boggling rate of 3 seconds per frame.

I've implemented autosaving for certain game data in CrossPaint, and I felt compelled to talk about UNROM512 / GTROM flash saving in general. [And some methods for detecting errors.]

Homebrew devs: if you have a game that you want me to add to my Powerpak so that people can donate toward it being played at the Spectrum Marathon this weekend, send the ROM to the email address in my profile. <3

Tomorrow may be a difficult day for me. I'm questioning the wisdom of leaving a job I greatly enjoy and is quite relaxing, a tiny company with some great people (incl. kevtris), where I've achieved a good level of expertise after 14 years. Onward into the unknown.. wish me luck.
Update, if anyone is curious. My job as an ET for the USPS is going great. Reactive maintenance is interesting, it gets pretty busy.. sometimes.
