To get into the interburst space i poll the clock line and start a time delay (about 1 ms)

I didn't want to poll, I w0ant0 this to be entirely interrput driven. looking for that clock pulse is too easy to miss.
To recombine serial data my above int0 routine writeszeroes or ones to bytes (inc R0). After that i assign values writing to the bit area (from 20h up)

No, clock them into a byte with MOV C,Px.x, then RRC
But now I fear that these LOW COST toys may have some problems on their serial data output....as they are sold with the advice: interface not available.
Could it be second or third choice?

No, the main problem to me is the difficulty of getting the damned connectors.

Really I should have put together a serial to parallel converter system, then the 8052 but I didn't have time.
You only need to get data three times/second anyway.
