It&#8217;s one thing to see photos of the MOnSter6502, but the video really brings out just how awesome this thing is in person!

The computer I&#8217;ve designed for it uses another microcontroller to simulate hardware peripherals, inspired by capabilities of various &#8217;80s computers and gaming consoles. The idea is to offload CPU-intensive video and sound tasks to the microcontroller, freeing up the 6502 so that it can be used in real time despite the slow clock.<\/p>\n<p>\nRight now, I&#8217;ve implemented several software-defined peripherals<\/p>\n<ul>\n<li>VGA video output with 256 color graphics, tiles, and sprites<\/li>\n<li>Multichannel stereo sound synthesizer<\/li>\n<li>PS\/2 keyboard interface<\/li>\n<li>KIM-1 style front-panel debugging keypad and LED display<\/li>\n<li>USB-CDC interface with a 6502-accessible UART for communications with a host PC<\/li>\n<\/ul>\n<p>The computer can also run a full validation suite on the connected 6502, which has been quite useful troubleshooting the highly complex MOnSter6502 boards.<\/p>\n<p>The computer is still a prototype, but you can see some shots of it in the video above.<\/p>\n<p>You can find more updates and information at the <a href=\"http:\/\/monster6502.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">project site<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It&#8217;s been a while since we&#8217;ve had an update to the MOnSter6502 project&#8211;we&#8217;ve been very busy getting the second revision ready.
