    Edit: Correction. No, 1.10 is too old. Flash support was added to the core in 1.14 (10M08) and 1.15 (10M04). Do you have a USB blaster?

     

    Yes, I have. STANDARD 10pin.

    Then match the two letter version code. NB this is the one you have a licence from Retronics for. You can downgrade for free, but to upgrade you will need to pay the difference to @Duddie

    The versions are:

    • stereo_covox_sample_auto: SC *
      • EXT1:A4, EXT2: A7, EXT3: GTIA AUDIO

    **developers only. Users should get v3 to use all chips, which is now available for pre-order here 

     

    I'm interested in change core to SC* then - I'll contact Duddie for payment.

    I already preordered v3 :)


  2. The earlier tape drives would be very unlikely to operate from SIO power. As it is some of the decode circuitry of the 410 and 1010 actually uses that power already.

    The XC tape drives benefit from better motor technology. Consider size and power consumption of early 5.25" floppy drive types vs the 3.5" ones once they'd been around for a while.

     

    In case of 1010 when you look at schematic:

    looks like reason for 9V is only motor. And looks like it doesn't make difference if its DC or AC (because of Graetz bridge at power input).

    Maybe there is a chance for changing motor to 5V and then it should be operable from SIO only - just a question?
