I thought this would be of interest, especially to those who might already know the software.

i.e. The Latest Alpha version of 4.3.2.01 contains support for the following:

Toshiba RD-XS32, 50, 52, 34, 54, 35, 55, 34SB, 34SJ extractions are working.
Philips 3575 and 3576 extractions are working.
Magnavox 2160 and 513 extractions are working.
RCA DRC8030 extractions are working.

The Alpha 4.3.2.01 is available for download from (here)

I've posted a video of the process with the 3575 (here)

Commentary and bug reports are being invited to improve the software prior to official release.
