The key to the RRD (recoverable ram disk) was that the Amiga OS memory allocation call allowed you to specify where the newly allocated memory should come from. The basic call always allocated memory from low memory upwards. But there was this other call (or maybe it was the same call) that would allocate memory from the top down.
MEMF_REVERSE ;AllocMem: allocate from the top down
There is some new AllocMem() flags that would have made your life much easier back then...
MEMF_LOCAL ;Memory that does not go away at RESET
MEMF_24BITDMA ;DMAable memory within 24 bits of address
MEMF_KICK ;Memory that can be used for KickTag stuff
Some of us are still programming you know. The Amiga is too good to let disappear
. A lot of people have come back and are having fun with it. There are lots of good forums and enough new hardware being worked on that it can't all be vapor ware. I love 68k assembler programming as well. You should check out

What format is the ASDG software tape backups in? Maybe someone here has the right tape drive. You should release the code and programs to Aminet. ADPRO at the least, had some features like a large variety of dithering types that would be very handy in other projects.
