I have (goes and counts them...) 12 complete Profiles and 6 Profile
"motherboards" (part number 820-0055B or D suffix) of which
10 have piggyback Z8s (apologies for the Z80 typographical error). The rest are
one time programmed Z8s (part number 341-0171A)
.
	I have low level formatted one 5 meg drive.... and I haven't gone through all
8 formatter ROMs that I have.
	So far as I know (the ROMs were given to me by someone who had run an Apple
Authorised Repair Centre until he emigrated
to Australia) these ROMs were obtained straight from Apple on a visit to their
head office. These were used to format the
drives prior to shipment thereby obviating the necessity to have wads of Apple
///s doing that. The ROMs were programmed and 
burned specifically for this purpose.
