@nixCraft Ah, yesterday's turbo is today's snail. So much has changed and yet so much stays the same.
Now I've got literal microcontrollers that run faster and have more RAM: an ESP32-S3 Feather. I used two to make an RC car and wifi remote.
And such big cases those old beasts came in.
I still remember the first computer I used (age 3): an IBM XT in a flatbed case big enough to set the monitor on it. It booted games from 5 1/4 inch floppies, even though it had a hard drive.
