Please I need help with my E-Jam project

[tundesafe]

Hi Everyone! Please I'm doing a project on an Electronic Jam and I need any theoretical resources that can aid me in my project. For details on an existing circuit check https://www.electro-tech-online.com/custompdfs/2009/10/june99_EJam.pdf. Can anybody please forward any links that can be helpful to me or email any resources to this email address: tundesafe@yahoo.com. Thank you all for your help.

Projects from that site frequently do not work and use very old parts. TTL logic is very old and needs a high current regulated 5V supply.
