I have been reading the forum and gained some knowledge from the discussions about the finer details of Apple II motherboards (thank you for that) - but thought I would offer up my own for some opinion and my further education. As you can see this is labelled as an Apple II (not plus or Euro), has a serial number of 14,909 yet has an odd Apple Silver PSU that has a switch for Euro current as well as USA. It certainly works in the UK. Was this an Apple innovation prior to the EuroPlus - or has someone been meddling over the years?
Would like specially to gain your views on :
- Is it really an Apple II, rather than Apple II Plus - or is this the wrong lid ? (I think Ive seen some Apple II Plus's with lower serial numbers?)
- What revision of motherboard is this - there are no explicit markings that I can seeNOT FOUND: attached_image_#, do I assume a revision 3 ?
- What revision is the keyboard - its the shiney key type so I assume quite an early one? (also has the raised power light)
- What is the ROM card for - I thought Integer basic was on the motherboard. There is a switch on the card , I havent been brave enough to switch it over yet.
- The motherboard stickers says Feb 79 (7902) yet the main motherboard says Apple 1978.
Would be great to know a little more about a much valued and admired piece of history. Thanks in advance for your views.
Probably a non-plus, simply because the plus ROMs are on the external card. But this was a completely customziable thing at the time from the factory and by the user. There is no definitive "plus vs. non-plus" test.
Lift up the CPU and see what's written underneath. Looks 3ish from what you've pictured so far.
It lets you choose between Applesoft and Integer BASIC. Flip the switch and hit reset.
7902 is the second week of 1979, the manufacturing date. 1978 is the copyright date.
the ability to switch between 110 and 220 Volt was allready offered with the II models... it was offered to business / traveling men from Apple and could be ordered from factory or from Apple dealers shop ....
It would be nice to have a picture
of the computer with the lid off showing
the entire motherboard.
This one looks about like my Apple ][, Date of Manufacture: 7916, SN:25422...
It has the 110/220 VAC Power Supply too..
