Topic: Load accumulator

This is episode 169, known to hex enthusiasts as 0xA9, known to
6502 opcode enthusiasts as LoaD Accumulator (immediate mode).
So, naturally, we
will riff on the topic of accumulation.

Topic: Retrocomputing Replicators

Part of the fun of retrocomputing in the modern age is seeing what we can do with new technology to help our old hardware do things that were never before possible, or difficult, etc. With relatively easy availability of PCB design tools and fabrication shops, people set off to make their own projects, and share them. And maybe make a few and sell them. And people want them, and then they run out of time, interest, materials. Could things be better?

Topic: Computers and advertising

In honor of the Big Sports Game in the US, we attempt to talk about computers and advertisements. What advertisements made an impression on you, caused you to buy something? Were advertisements really mostly aimed at kids? Or were those just the ones we saw because we were kids? How have things changed? Did Carrington appear in a Quark ad campaign?
