 |  TSS3 DiskTurbo doesn't load with Datassette attached
I used TSS3 DiskTurbo, my prefer one, with and without Datassette attached: it worked when there was no Datassette attached, but it didn't work with the Datassette attached, giving back the ?LOAD ERROR message during the loading phase.
Can someone confirm this?

Hi Luca,
I can confirm it sort of - you know, one measurement is no measurement. I made one attempt to load one and the same file with and without the 1531 connected. When connected LOAD ERROR, when not READY and the program ran as it should.
It is very interesting that the other day I read in a forum topic on CSDb that the very same loader that runs fine on a C128+1571 combo breaks when run on a C128DCR. The guys were talking about some electronics issues. Maybe the same applies to this case too.

It could be a very simple error of not setting the CPU data direction register ($00) properly. When the datasette is attached the tape sense line is high (AFAIR) otherwise it's low. So setting the data direction accordingly (tapse sense line bit to output - which input by default - in the DDR) might fix the issue entirely.
EDIT: Try POKE0,31 before LOAD-ing...
