This is Conway's Game of Life, Gosper Glider Gun, running on Chad Burrow's V2 board. The Life's Universe residesin the VGA's 64x48 text memory, so it is small and run quickly. The CPU clock is 14.7MHz, so I added delay between each iteration of life. The program resided in EPROM is quite small, lesser than 600 bytes.

You are getting more use out of it than I am, haha! That would be perfect for Math Appreciation Day 2022. Great, thank you for the program Bill, I will be putting it to good use!

I have not used VIA (65C22) before so V2 allows me to explore VIA's functions. I was under the impression that VIA's shift register can be used as an UART, but that doesn't appear to be the case. (Please enlighten me if I'm mistaken about VIA shift register's capability.) In order to have a serial port so I can load and execute software, I added a W65C51 to the expansion port. I ported a simple 4-function monitor so I can load, examine, modify, execute files.

There are room on the expansion board to add PS2 keyboard and LCD interface. However, I have a batch of pc board coming in today or tomorrow, so this is all I can do for a while.

You can sort of use it for transmission. See viewtopic.php?p=2308#p2308 in my "Tip of the Day" column.

What's an additional VIA among friends, anyhow?

This is the wiring diagram for Chad's V2 expansion with W65C51. It will be misplaced soon so I better document it and post it here along with the software.

Update the monitor to V0.2 to fix a file load bug.

Now that file load is fixed, here are three programs that can be loaded into RAM and run:
memtest is loaded at $200 that tests RAM from $300 to $7FFF
matrix is a matrix-like screen saver that loads at $1000 that drives VGA display (need VGAxRAM)
life6448 is Conway's Game of Life, Gosper glide gun, that loads at $1000 and drive VGA display (VGAxRAM needed)

Hey everyone!

So Bill sent me his working board for me to use during Math Appreciation Day on April 21st. After a bit of tinkering it is now working!

Thank you Bill, you have been very patient with me during all of this. I am happy that there is something to show for Math Day now.

And now hopefully I can add to the list of displayable units.

Just an update!

Chad

EDIT:

Since I'm on a roll it seems, I converted the old assembly code into my new stuff for V1, the mess o' wires. Yay! They are like a little family now :)
