6501 photo and datasheet

Posted on 27/09/2018 by hanso

The MCS6501, a first and very rare member of the MOS Technology 65xx CPU family.
Introduced in 1975 with the MCS6502 to MCS6505, pin compatible with the Motorola 6800 and, after legal issues, not produced afterwards.
The (preliminary) datasheet of August 1975 is the only document where the 6501 is documented
