Teensy 3.5 Arduino sketch to program 29EE010 Page-Write EEPROM devices
Bling code for Burning Man bike with 31+36 DotStar LEDs
Developed as a by-product of the IBM 1620 Jr. project, the Cadetwriter is a general-purpose ASCII terminal. It can be connected via RS-232 or USB to any mini, micro, mainframe, or replica computer as a terminal device. A commercial quality IBM/Lexmark Wheelwriter 1000 was adapted by interposing a circuit board containing a Teensy 3.5 microcontroller between the typewriter's keyboard and motherboard. Custom firmware controls the typewriter and communicates with the host computer. To support the full ASCII character set, characters not on the printwheel are synthesized using overprinted characters and "period graphics". The Cadetwriter can print up to 16cps and is a reliable, low-maintenance, low-cost substitute for Teletype, DECwriter, Diablo, Spinwriter, Imagewriter, etc. teleprinters.

Julie's Race, a C64 BASIC game recovered from 1983(?) floppy disk. I wrote this one afternoon on holiday in Orange, TX for the amusement of my niece Julie. If she could type a single letter correctly, four character-graphic "boats" would race across the screen accompanied by "music". She cheered for the green one.

Failed attempt at a Teensy 3.5 Arduino sketch for dumping the memory of a small-scale NEC V20-based system, such as the IBM Wheelwriter 1000 typewriter upon which the Cadetwriter is based. The attempt failed because it turns out the glue logic chip on the Wheelwriter 1000 logic board interferes with this method of accessing the ROM.
