re. what's a MAC-10A?

Ken,

I opened up the MAC-10 and compared to a MAC-11C.  You could observe some
minor engineering changes - few variances in components( resistor, caps),
but otherwise functionally equivalent.

I installed a QLCC chip in place of the MAC-10 chip.  Works great!  So if
that is what you had in mind, no problem.

My recollection is this came out of an '87 5000 turbo quattro.  Don't know
why they had this version with an earlier number.

[I got one of these MAC-10's which came out of an '86 or '87 Turbo Quattro
too.

I'd be interested to know if there is any difference between the MAC-11
series, other than the code on the PROM.

[Hey list,

But my real question is, while I was pulling the programmer out of my donor
'87 5kt, I saw the ECU and it
is a "MAC-10A".  I had only heard of like MAC11's and 14's and the single
digit MAC's that I can't
remember right now that go in the ur-q's.  I found one post of one for sale
in the archives, and one lister's
drama trying to get an umodded one back from TAP, but not much info on what
it is.

This car is supposed to be an MC-1, and I thought therefore it was a
MAC-11A or MAC-11B, but surprise.

What's a MAC-10A?

Thanks,

Ken]]
