Sorry, I should've clarified the SE & SE-FDHD situation. I have both- I'm keeping the FDHD and repurposing the SE. The FDHD will help me get files onto an 800k floppy since the iMac's USB floppy drive can't.

I'll edit my original post to reflect this.

Pyro is 76k, leaving plenty of room for System 6. The modules are between 8k and 32k. Obviously I only need one or two.

Fitting this stuff onto a floppy with System 6 is not my major concern right now- finding a program or control panel that does what I want is where I'm having problems.
