Snagged a bunch of System 7 software for $2 each:

Now Utilities 3.0.2

Aladdin Spring Cleaning

Shanghai II Dragon's Eye

SuperMac Super Laser Spool

And perhaps the coolest of the lot:

PrintLink Collection from GDT Software

It's a collection of 8 printer drivers that work with about 30+ different brands of printers (I suspect the majority of them are all just rebranded printers of those specific 8 printers), some special screen fonts that work with a few specific printers, and a special serial-to-parallel cable. This enables you to print to print to a crap ton of different PC dot matrix and thermal printers.

How I wish I had this back in the day as I longed over the the much cheaper priced parallel PC-only printers.
