[Ludis Langens]

Gee, now I know what car(s) some of you are interested in!

Bruce, your "GN87.BIN" and "89TA.BIN" dumps contain garbage.  The other two
sumchecked fine, although the "TURBO42.BIN" had eight extra bytes at the end.
Interesting that your "stock" PROM differs from Mike's by one byte (plus the
sumcheck.)

For future reference, what ECM number do these PROMs go with?  And does
someone have a dump (to post) of the 8K of soldered in ROM from this ECM?
