Pony80: Clock Circuits

Pony80 ROM/RAM Memory Module Video

In this video I build the ROM/RAM memory module for the Pony80.

I also go into detail about the logic chips used for selecting which chip should be active. 

The Pony80 has 8K of ROM, with the ability to page it out to RAM via an I/O call.

It has 128K of RAM; however, we are only using 64K at this point. I do want to add the ability to page different RAM zones in and out so we can effectively use all 128K.

Watch the video and then come back here for schematics, datasheets, and a few links.
