I have a few sets of upgrade parts for the original Tapr Trakbox to convert it to a Trakbox Turbo at 4 times the processing speed. This allows faster tracking of higher frequency doppler shift and generally improved communication with computers.

The kit includes new 2X processor (80c320), faster eeprom, faster address latch, double speed Xtal. The new prom is already loaded and all chips are tested in one of my Trakboxes before I send them. The price is right and I will include all documentation. I will offer support to assist with questions. Email me if there is any interest.
