I used the 1581 to develope assembly routines on the Vic20 and to run
programs from on the autobooting Plus/4 but I have not used the 1581
with a c16 - do recall that the 1571 boots into its 2Mhz mode at
startup (+/4 supports 2Mhz but not the burstmode so it talks at the
regular 1mhz AFAIR) but when the non-burst mode commodore boots it
resets the drive chain and that puts the 1571 into 1541 mode (as does
opening a channel and printing to that [Open 15,8,15,"u0 > m0"}
