View Full Version : Apple ][ motherboard questions

October 28th, 2013, 03:43 PM
I just acquired 3 Apple ][ motherboards in various conditions. I am not too up to date with revisions, but I am trying to figure it out. I believe this first one I am posting about is an original Rev 0. The person I bought it from repaired and tinkered a lot, so I am trying to make sure it is authentic and has proper ROMs and other chips. Info is plentiful, but some sources are varied. I have a power supply from a ][e, but have not tried it out yet.15731157321573315734

Looks like it has the Applesoft / Apple ][+ ROMs on it, not the Integer BASIC ROMs that would be correct for a Rev. 0 Apple ][. Otherwise a great find, not too many of the Rev. 0 boards out there.

I think this might be an early II board upgraded to a II+. date stamps on other TTL parts indicates they were manufactured in 1977. the serial number is a real serial number and not a year/week number.
