The D-jetronic system on my old 2.0L 914's had an analog computer,
actually. I still have a spare somewhere. I opened one up one time
and it was pretty much all discrete components- transistors in op-amp
circuits, etc. The biggest problem with these systems were various sensors
(the manifold pressure sensor mainly), trigger contacts in the distributor,
etc. failing. None of these parts were cheap from Bosch or the Porsche dealer,
either. A lot of people just ripped all that out and installed dual 48IDA's,
but when it was running right, the multiport injection made just as much if
not more power, and you could get close to 40 mpg. cruising at 90-100 on the

Automobile Atlanta in Marietta GA stills sells this stuff. They have whole
cars even. I always squeal like a stuck pig at George's prices, but
they're actually pretty reasonable, considering the amount of storage
he's got in them by now.

To take this back off topic, when are we likely to see a niche market for
restoring old computers, "hot-rodding" them, etc. on a commercial
level? Or will we ever? I know nobody here wants to have anything to do
with dealers, forking out the loot, etc. but if you're looking for old car
parts, they are usually pretty easy to find if they exist. And if not,
someone will make them if there's enough interest. That *could* be a problem
with IC's and PCB's, but most of the rest of the components of old
machines could be easily reproduced in a modest shop.
