Foto review of the Serial cable and Transfer program:

ADTPro may be used to transfer Apple diskette/disk images in DOS or ProDOS/SOS format.

The Apple client side happens to run under ProDOS or SOS, but it is perfectly capable of reading or writing Apple DOS (or Pascal, or CP/M, or…) diskettes.

I’m the creator of the SID 6581<>8580 Switcher (here the original project).

I’m Very happy to see my project on the net. Arkanoid (a user of Lemon64 Forum) has done a very nice PCB with some fixes. Very nice job.

This is not a SId2Sid Clone.

The PLA chip (906114-01) used in the Commodore C64 is a generic 82S100 gate array with custom programming.

Its logic functions were dumped and reverse engineered by the community and are available from a variety of sources. This PLA uses the Xilinx CPLD XC9536 to emulate perfectly the PLA of the Commodore 64.

Sound fix diagram here. (pdf)

from Cristian Secară Homepage:

The first release (the +3) has a fatal hardware mistake: the 128K sound output is completely distorted.

• Tech explanation: the analog output of the AY-3-8912 sound chip was intended to be amplified by a one stage common-emitter transistor. In practice, they have forgot to put a resistor to the transistor’s emitter. The result: the transistor works in switch-mode – the sound is converted from analog multi-level amplitude to digitized two-level amplitude, same as the old 48K sound system.
