If it is an early ROM version, it would be neat to use that with the 128k minivMac and see if there are any differences. .If the hand-written labels are correct, then it isn't an early ROM version. ROM 7.0 is the shipping version of the original 64K ROM.

Dog Cow - thanks for the info. Now to really get together some old Mac's and 400K floppies! Have to get MacsBugs installed on one with a system. Maybe too, I can boot from the internal floppy with the system I have, then run an external floppy with MacsBugs, and CopyROM (thanks @LaPorta) for that link.
Below are photos of each of the 512K adapter board that is on the logic board of these units. Any clues here without running MacsBugs? It is a shame that so many of these early Macintosh units end up in the hands of people who are not equipped to adequately evaluate or document them, and then say things like, "Before I unleash it on eBay.... $10K US"
Before I unleash it on eBay, which might cause a frenzy, anyone here interested, have the money, and is interested? This unit would be next-in-line to that Twiggy version that is all over the web. Thought that I would do the respect of asking here first. $10K US - am I nuts?
When the Twiggy Mac prototype surfaced a few years back, it was almost exactly the same scenario as this. :-(

Dog Cow - thanks for the expert confirmation of the ROM - helps round out the history and description of these machines. Not sure how to take your other comments about "end up in the hands of people who are not equipped", etc. This is why I have come to this forum, and why the other contributors assisted in understanding what these computers are.
