There is the Heath User Group, who distributes a fair amount of
stuff in hard-sector format.  The _only_ other option is to 
hook up a serial link (preferably at 9600+).  My tertiary 
system is a Micropolis-based machine, 16-sector, 77 tracks,
SSQD, 315K per disk.  It doesn't have a whole lot, since I
have never managed to get a serial port to cuntion with the 
odd system clock I have on the CPU (1.8432MHz - most S100
systems demand a 2 MHz clock for a serial port).

Actually, as late as three years ago, you could have gone to a
Heathkit store for conversion.  A lot of them had -89's with 
two controllers in them.  One of his options is to add a second
disk controller (soft-sectored, of course), which will give him
a bit more storage to boot.  So I misspoke.  There are some options.
