Re: Tweaking a 9010 z80 pod to be a z80b pod?

Hmmm...Intereresting.....

I've not got my hands on a Z80 pod yet.... ( will be borrowing one once I
can go and sort a deal out), so can't comment on the cable fitted as
standard.....but I do know my 6502 pod has a twisted pair cable though.

Thanks for the insight...

Regards, Colin
