Figured out my next angle of attack for reverse-engineering Time Machine's ROM in the shower this morning. I need to find the code that converts ASCII characters into 7-segment and alphanumeric display segment patterns. I'm assuming I'll find a lookup table, and that references to that area will point me toward other text and score handling code.

Printed myself a 68xx #reference guide and put it in a binder. It'll be nice having a paper reference while I'm working on the Time Machine #Pinball #disassembly effort.
I've really been enjoying having a color #printer of my very own, and I'm especially happy about the fact that I haven't even put a visible dent in the ink tank fill indicators from the first fillup. The #EcoTank was pricey, but not having to be skimpy on ink usage is worth it.
This year's special theme of the "Vintage Computer Festival Europa" (#vcfe) is "50 years of #Intel8080 and #Motorola6800" with presentations and talks about these #8bit #microprocessor and its implementations.
Nevertheless, I will exhibit a scientific poster (and a #BreakOut-clone for my #Mega65) about my #BASIC researches and give a talk about #PaperWare #Preservation there.
So, join the #vcfe from Sa, 27.04. to Su, 28.04. and visit my exhibition and talk! :)
