SN76489 Card for HBC-56

[allanfherrera]

As I delved into the project, I entertained the idea of exploring an alternative approach before proceeding with the creation of a Z-80 card for the HBC-56. Specifically, I am considering the development of a sound card featuring the Texas Instruments SN76489 chip(Also used on the SEGA Master System and the BBC Micro).

I have come across the Baffa-2 Sound Card, designed for another Card-based homebrew computer, incorporating the same SN76489 chip. I believe this could be an interesting starting point for our endeavor. For your convenience, I have attached the relevant documentation: BaffaVision_Soundboard_SN76489_rev1_PCBWay Community.pdf.

I would appreciate your insights and feedback on this proposal, as well as any guidance on how we might proceed with the development of a similar sound card for the HBC-56.

Thank you in advance for your time and consideration. I look forward to your response.
