This wasn't getting the attention it deserved in another forum so I felt it appropriate to move it here.
I am most interested in knowing about the MacSnap 5.0 "RAM upgrade" (without SCSI, compatible with the stock 64k ROMs) that was made for the Mac 512k. I believe it came in two flavors: 1MB & 2MB. However, I've spotted 3 model numbers on the web: 548, 548E and 548S. How other than examining the markings on the RAM ICs can one tell the difference between the 1MB and 2MB boards? And what are the specific differences between the 3 model numbers? (Equill apparently owns the 548E board.)
And would anyone happen to have documentation for the MacSnap boards? There is a DIP switch on top and without the documentation it's impossible to know what the correct settings should be.
Here is an original Dove ad talking about the MacSnap products.
Thanks.
