One of the things we didn't have back in the day was an alternative FS to FastFileSystem. In a sense, it was all about using FFS instead of OFS (the native floppy FS) from the get-go back then. I think it was even Gerard Bucas (President/Fmr C= VP prior) that hashed out the pre-1.3 RDB+FFS that GVP used in 1987, and C= ended up tweaking the idea for the HDToolBox/A2091/A590 boot block (the A2090a used a boot block, but OFS in the ROM, until 2.0 and the discontinued the A2090/a.)
One of the things we never had in FastPrep/ExpertPrep is picking alternative file systems. Having a Buddah now, I have a better feel for what is involved. I have the source for Fast/ExpertPrep, but have had no time to add the things that it needs. Maybe one day.
I wish I recall more of what I tried and failed to do with the Buddah when I first tried to prep a disk/media on it. I'd pass it along. I didn't think to seek out support then as I knew I would figure it out eventually - and did.
