Wow! And those TV's were made out of very sturdy glass as opposed to the weak plastic lcd tv's today. Imagine how angry you had to get in order to throw a snes controller trough your CRT. I have gargoyles quest for the gameboy (which is a spinoff of the franchise starring the red demon as the main protagonist) and it's hard as nails. You have to remember the levels and attack patterns. You will inevitably die the first couple of times and progress slowly trough the levels. Enemy placement is sometimes incredibly cheap and on the original gameboy they are very hard to dodge too.

I got all of my calc files backed up on my pc and I never throw away any backups. Yay for 1TB hdd. Never worry about file size!

Barely 1MHz? Can you do anything useful with that thing?

About 1 hour to write the code and about 10 hours to find that one annoying bug.

Yep. I got about 26GB of dropbox space for free because our university participated in the great space race I use db a lot.

Of course that will work. If you have a 12 bit analog to digital converter with an I2C bus you could interface it with the 84+. You'd need to implement the I2C protocol in software though.

I made a 4 bit one for use with calcs once. I tested that one with different waveforms as well. I even tried converting sound samples to calc format, but it did not quite work.
