    Mini-Review: Liligo ESP32 VGA+FAB-GL Library/PC Emulator Demo

    I'm not sure how people on this board feel about emulators, but... I have been spending the evening playing with the LILYGO TTGO VGA ESP32 Module V1.4 and FAB-GL, a very nice Arduino library and it's "demo" IBM-PC emulator.

    Retro-Retro Computing Repairs

    i built a few boards about 20 years ago that demo'ed the 8008 and the 8080 with scrolling descriptions of the chips. I pulled these out of storage to look at while I was building new 4004 and 4040 hardware. They didn't seem to want to reset anymore. It turned out that although my wire-wrapping...

    ESP8266 Based 8008 Emuilator with PS/2, NTSC Out, Paper Tape

    VT320 CRT Replacement -(Mostly) Successful

    So, I was playing with my VT320 terminals that I painted and cleaned a few years ago. One worked very well, but one was dim even when turned up to max brightness. Both had burned amber CRT's. I thought that it was now or never on the CRT's, so I searched around for replacements. I ordered a few...

    Tiny, Wireless 8008 Emulator

    I just finished this up well enough to show: https://hackaday.io/project/28227-esp8266-based-i8008-emulator This is an ESP8266-based Intel 8008 emulator, running SCELBAL and the Shooting Stars game from flash. It's only about 1" x 2" x 1.5" in size, and housed in a dollhouse-sized walnut case...
