Here's an interesting use for the built-in memo pad:
I acquired my first Atari 8-bit system (an Atari 400, a couple power supplies, basic cartridge, some disks, but no disk drive) a few weeks ago on the local freecycle list. I was clueless how to get the video from the device to show on a modern TV, and hadn't done proper research. Then I had to put it aside for a bit.
A fellow in my town hosts an annual
Atari Party. At the show there were several stations set up with lots of adults and kids playing and experimenting with the machines. It sounded like an arcade from the early '80s. Fantastic! So I brought my newly acquired Atari 400 to the show to see if anyone could help me evaluate whether it works or not. I happened upon one station where a fellow had his 400, 800, and 1200xl set up. I asked him if we could diagnose my 400, power supplies, etc, and he immediately indicated to me that he was completely deaf. We communicated quite effectively by taking turns typing on the keyboard into memo pad. I learned that my 400 is completely functional, the basic cartridge works, both power supplies work, and the floppies are all readable. He also showed me the proper connections to connect it to the TV using the game/tv switch in my kit.
Then later on there were several raffles. Each attendee was given two raffle tickets and allowed to submit them any of the raffles. I submitted both my tickets to the Atari 800 raffle, and I won it! It's a very nice Atari 800 kit (incl disk drive, basic cartridge, USB downloading cartridge and flash cartridge, several books, power supplies.)
I'm set for a while on Atari stuff. I don't have a whole lot of cartridges, but I'm more interested in the hacking and programming aspects anyway.
