I uploaded two new Simon ROMs, version D1 and D1b. I found these files while I was preparing a new Simon. I'm just posting them so if anybody finds anything useful. (I'm shipping Simon6809 with D1b version).
Last few weeks, I have been learning vhdl to port Simon6809 and Simon6809Turbo to altera fpga board, de1.
Here is the first run of the 6809 processor and simon6809 monitor code.
I borrowed the cpu from John Kent's website.
I'm not going to release the code yet because it is my first real vhdl coding. so i don't want to embarrass myself.
One thing I realized is regular uart is WAAY slower than ftdi.
I had to kill my original website anynewgizmos.com that was hosting Simon6809.
It was interesting to see a few people mention it and actually link to it. So, here I bringing them back to life.
Well, I also have a surprise for you. I have been working on its big brother, Simon6809_Turbo for a while. I came to the point where it boots FLEX operating system from ramdisk, console over uart (ftdi). the next step is to implement a FAT16 FS and boot from the sdio card directly. the problem is I have too many projects going on right now. any takers?
I grew up in 1980’s Where computers took the whole world suddenly. we were worried about artifical intelligence taking over, and then 1990’s and y2k problems. good ol’ days.
I love 8-bit microprocessors. this page is dedicated to 8-bit everything, including computers, music, art, lifestyle, anything you can think of.
I have been thinking about creating a website like this for a long time.
So, this is my very first posting. It should give you an idea of what I like:
