OK - this just kicks ass! Using CopyR 2000 and a POKEY divisor of 1, I can read a full 180K/sec in 24 seconds. That is a full 7.5KBytes/second.

I hope there is a way to make more programs run at this new xfer rate.

Thanks a ton Steve.

:shock: -> :)

I'm happy its working. There probably is very little if any difference between 0x01 and 0x00, so thats top speed.

Just curious: What pokey divisor does APE 3X and Happy modes run at? Also, what baud rate do these divisor's equate to?

3X sio is 0x08, which is 59659 bps on a NTSC machine.

The Happy 1050 high speed mode is 0x0A, 52640 bps.

Is the APE Warp OS automatically using the ultra high speed of the USB interface?

If so, how does the OS know what the supported transfer rates are? Do "enhanced" drives have a command that returns the pokey divider or baudrate?

The Warp+OS rom will only go up to 0x08, though I'll fix this in a later revision.

If you use one of the OSes with Hias's SIO patches, you can get up to 0x03 or 0x04.

I'm not sure if there are any general purpose OS patches that go higher than that, though some software can, like the COPY2000 program seen in the video.
