Rockwell AIM-65 6502 Vintage Computer: Display Board, Speech Synthesizer, Basic, and Forth

I explore the Rockwell AIM-65 vintage computer. This is a 6502-based computer from the late 1970s. This computer came with 4KB of RAM and 20KB of ROM, and had some kind of calculation program installed for what I think is a manufacturing company. It came in a nice all-metal industrial case. I build a display board that uses the 6545 CRTC chip to render composite video. I also build a speech synthesizer using the SP0256A-AL2 speech synthesis IC. I also demonstrate using BASIC and Forth languages, and establish a serial connection to the vintage computer. For more vintage computer videos, see https://www.smbaker.com/
