ANN: Project VIP : Elf/Cosmac VIP/Studio 2 Emulator in Hardware.
- I have been working on my hardware-based Cosmac VIP / Elf / Studio 2 emulator and have got most of it working :) I want to revamp the keypad code and find a better way of uploading files into RAM memory.
It is an Arduino Uno or Mega2560 (the main difference is the amount of RAM available - 1.5k on an Uno, 6.5k on a Mega2560 due to internal SRAM limitations) with a couple of resistors, a piezo buzzer and a keypad.
The video shows the Cosmac VIP version running "Brix" on Chip-8 then the VIP Monitor running. The sound is not recorded (though it works fine) and the display is solid - on the video some bits flash which is the video recording/processing, not the system itself).

I have a number of magstripe card readers if anyone wants one to play with, I'll be happy to send one for just the price of postage.
