Actually Dennis, it's probably a lot easier and cheaper to buy a Mac Plus off eBay. They are plentiful and cheap. It will also give one a place to safely store those removed parts from the 128K. Besides, I always recommend anyone with a 128K to also own a Plus since it is so similar to the 128K and has a SCSI port for use with Zip drives and such for transferring files back and forth between OS X and other Macs, and very helpful for troubleshooting and creating 400K disks. Easy to swap out and return the parts as needed.
