Making a homemade 6802 computer for fun.

I have been reading about the 6800 series microprocessor. So far I have learned a lot. I would like to learn more but lately been running out of time for my projects. I have a side project not posted that has took some of my time. The rest of my time has been going to my recent marriage. :)

This picture is from Amazon where I got the book even though this isn't what the book I got looks like. I will upload a picture of my book sometime later. :)

I need more stuff if I am going to use the MOS 6560 chip for video. The 6502 isn't far off from the 6800 series chips if what I am remembering is correct. I believe there was a whole court case from Motorola to MOS because they were selling the 6502 CPU that is compatible with 6800 series for $25 instead of Motorola's $100+ and Intel's $100+ CPU.

The 6502 is on the top left and the 6560 is on the middle right.

I am assuming I need the 3 Octal Bus Transmitter/Receivers at this time.

I am going to try and use the Commodore VIC-20 chip for video on the 6802 Build. Mostly because I have no other chip that can do what this can do.

My latest update is that I am making a new schematic on Eagle Cad. My only problem was I had to learn how to use Eagle Cad. I didn't find that being a problem for long as I watch a lot of Ben Heck YouTube shows. His show on Eagle Cad was right to the point.

Next step will be ordering a custom PCB after I finish with Eagle Cad.

In other news I found out from a lot of reading of datasheets that the 64k EPROM (27C64A) I have can work. That is also the max the 6802 can use. I will save the 32k for another day. Maybe on a Z80 build if this works out alright.
