Cockroach Turbo-ROM

Cockroach Turbo-ROM is actually just Turbo-ROM but since Datel has the Turbo ROM II and most internet downloads go by adding the company name we stick to it here. Just like Speed DOS this ROM provides a nice deal of functionality and is definately worth a second look. It does not require a parallel cable to operate and comes as a C64 kernal replacement only. The tape and RS-232 routines were removed to make up the required space for:

Functionality

fast serial I/O on load, save and verify (excluding USR and SEQ)
fast format
OLD function
ZAP function
DOS wedge
works with several drives
text mode printer screen dump
save-@:replace bug fixed
MON function runs a monitor at $8000 or $C000 (one may argue about this "feature")
