This folder has some pre-made blanks in it of various sizes:

I have seen and perused this file depot in the past:
Pro:
-there's a nifty 1 Gb HDA volume formatted for Mac Plus that avoids HD drivers such as LIDO, AFAIK, it uses SilverLining.
Cons:
-When a 1 Gb volume crashes, it can go into a "corrupted" state and never be able to boot from it again on my RaSCSI.
-Reuploading a 1 Gb every time I get a hard crash gets old. Not so with a 40 Mb file.
-I don't seem to be able to retrace the steps needed to take a blank HDA file and force-shove it Silverlining myself. I've tried with a 5.x version of Silverlining, but I guess the parameters I chose did not clinch it. I'm missing crucial step(s) needed to make it 100% Mac Plus friendly.
Needs:
-I'd like a lean and mean *pre-installed* 40-60 Mb Silverlining Mac Plus HDA volume with System 6 and another with System 7
-Failing that, a nicely curated Install folder of 6.0.8 and another for 7.1 that doesn't trip on needing to insert a physical disk (ie- not depend on mounted virtual disk images).
-I can't use Disk Jockey myself, which allows an arbitrary size and specific HD driver of your choice. Just, nobody has made lean images for Mac Plus yet, there are only these jumbo 1+ Gb things.
