TRS-80 Model 4 Gate Array FreHD Autoboot ROM (2764)

This EPROM is required if you're interested in being able to boot your FreHD automatically when starting the machine. It is supplied on a 2764 EPROM which requires soldering wires to various points on your TRS-80 motherboard.  There are no trace cuts, only soldering. If you need to reverse it out, just remove the chip and clip the wires.

Only one chip with wires and instructions is included with each order.

(We are charging only for the EPROM (nationally sourced) and the programming, not the code. The code and instructions are freely available from "The Right Stuff" and used as such)
