Finaly got back in. Wow love putting out fires and bored clients!
The site I was thing of that did have the H configuration of a Bit Char-G H bridge and was a Japnaes site! Also it the guy that has the Japanes semi with the umpteen lights on it.
This is it under dual and tripple speed section on his site.

Its basically the same but missing R18 & R17, direct connection to RX2 and the two cross resistor. A lot cleaner.
Could it be the spects on the transistors are different? Be fun to take a "set" from a bit pc board and replace the ones on a ZZ.
Since I am taking the next couple of days off, will get to "have fun" also!
PS: Wondering how close to ground the NPN are really getting down to?
