Hi,

But was the 6507 cheaper than the full 6502?

I ask because I got into electronics, as a hobby, in 1977 and a few years
later a magazine (either Practical Electronics, ETI or Elektor - I forget
which) published a design for a small "trainer" system based around the
6507.

At the time the 6507 was priced at two or three times that of the 6502, in
Europe, to hobbyists, at least. Not to mention that it was INCREDIBLY
difficult to obtain - so much so that said magazine ended up publishing a
design for a piggyback board to enable a 6502 to be used in place of the
'07!

I didn't get into commercial design work until the late 80's so I don't know
what volume pricing of these chips was like.

My gut feeling is that the 6507 was a cheaper chip (well it SHOULD have
been) but does anyone know for sure?
