I have a version of this I designed with some upgrades:

• headphone jack

• switch for enabling certain one-bit game sounds

• full 8-bit audio resolution for supported software

• smaller size

• modern components

I had a handful of boards made so I have some spares if anyone wants one.

Hi Abzman,

Welcome to the Exidy Sorcerer Forums.

Could we get some Gerber PCB files and a parts list together ? I would be keen to make one !

Regards,
John Halk

They're linked on my github and the pcbway project from the blog post, but I have 3 spare boards and parts, I can just make you one and mail it to you

Hi Abzman,

If you can put one together for me - I will reimburse you for the costs including air mail postage to Australia via PayPal family and friends direct payment.

Thanks,
John Halk

Yep, I'm also interested in a PCB!.

In fact, it comes in the right time as I'm finishing a port of the MPAGD engine for the Sorcerer and for now, there's no sound implemented. With this sound module, I can at least program some 1-bit routines or maybe some with more resolution if I can find the device's programming info.

Well, in 'music' mode the voltage on the audio pin is proportional to the 8-bit binary value on the parallel output port. That's it, count up linearly and once you hit 255 you count down until 0 and repeat and that's a triangle wave. The 1 bit mode just uses bit 0, but you can get the same effect by leaving it in music mode and playing with bit 7 (if I recall correctly). I'll build up the rest and get with folks on shipping stuff once they're done and tested.

While assembling the last of the boards I originally designed I wanted some revisions to aid machine assembly and subtle-ly add features. Version 2 has:

• Wider footprint for fitting two sizes of SOIC part

• All parts on one side to aid machine assembly

• using the switched function in the headphone jack to disconnect the RCA when headphones are plugged in

• a bypass jumper for the above feature

• properly labeled bit0 and bit1 resistors

You may notice that almost all the functionality is exactly the same, so I can't really think of much reason to want v2, I just did it because if I was going to do a second run maybe I'd fix some things.

I have updated the git repo, but nothing else yet because I haven't built and validated it yet, but here's a render of v2
