Yes! It is a good idea to see if this concepts also works on an unmodified 512K. First

on 512K with 128K ROM (512Ke) and if that works on a pure 512K.

I'm thinking on three ways of doing this:

- Try to setup an old boot disk with a System version prior to System 6 with

MacTCP. The oldest MacTCP I have is version 1.1.1. I have to find out or

hear from other users what System can be used with this version of MacTCP.

- Try to reduce memory with a tool like RamDisk. Or RAM cache...

- Replace the current motherboard with an other one I have. This is a

Macintosh 512K board with the DOVE SCSI snapboard. If you ony install the small board the motherboard has only 512K

I hope I get some spare time around Christmas to do this. Anyone with a pure 512K is invited to test also!

I'm now shutting down the 512K (1024K.... :b&w: ). It is been online for 4 days in a row whitout any problems.
