I have a 1581 fast loader that was from a magazine back in the day and
it is very effective. You can load a 200 block program in a few
seconds (like 5-7) but you have to have in memory obviously.
Michael Miller (the Big Blue Reader guy) published a loading system
for both the 1571 and 1581 drives in the December issue of RUN
magazine. It worked on stock C64s and in C64 mode on a C128.
RUN disk images are available here:
ftp://arnold.c64.org/pub/magazines/
There was a COMPUTE GAZETTE program
around the same time for the 1581 only.
The users of the RUN program selected programs to be loaded from a
directory listing. I rewrote the program so that the C64 system would
revert to the RUN program when a LOAD command was issued. I went
through the bother because my disks had HUGE directories, the 1571
code had a virus, and the drive code resided in USR files rather than
in computer memory. After the program as published was used, 1571s
overwrote BAMs on disks when a specific series of disk commands were
issued. I added a drive initializing command to the program to fix
the problem.
I use the program infrequetly since I now have everything on a CMD
hard drive.
