Hello,
I have bought the harness only package from an ebay seller named "cespok_64" from Spain.
He seems professional with a very good range of products for testing the TED family.
The status byte is 7 (I have read from the site about a possible issue on sensing or powering the cassette deck... but I have no idea on where to "put my hands").
I have been able to change the CPU to:
WRITE: 00 => ----....
READ: D0 => XX.X....
BUT I read on the 6529:
WRITE: FF => XXXXXXXX
READ: BB => X.XXX.XX
And if I press 2 nothing changes on READ...
I have written that I have problems also with the user port. I get 44 as status byte... perhaps the two problems are interconnected...
Thank you, Flavio
