Odd LC II Motherboard
Posted by: belgaonkar on 2017-05-28 17:47:13
Piggy backing on the other "odd" motherboard posts, Ive found an LCII board at the flea that is missing some of regular LCII markings. 

Firstly, the 4 main ICs have hand written tags on them. I haven't seen an LCII with these type of stickers.

Secondly, the motherboard's serial number sticker doesn't say the normal "LCII 4MB" it has the part number 630-0079-B

Finally, some of the other chips are of a different brand. The board in question has Motorola chips for DRAM whilst the production board does not.

This board does work (although It needs a recap) and the system recognizes it as an LCII.

Any Ideas?

Actually someone what common. The early boards had EPROMs like that and Apple sourced chips from multiple sources, so nothing unusual there either.

Interesting. A google image search of LCII motherboard doesn't yield any pictures of a board with the stickers and the lack "LCII 4MB"

I have one of those also (mine being the LC, not the LC II)

Not unusual.
