[Coco] Are MC68B09E's and HM63C09E's as well as various support chips still available?

John,

Look forward to see your work on the 6309. We have discussed this before. Glad to see that you are working on it.

Don't see the FaceBook function but....

Mark Marlette LIKES this post! :)

Regards,

Mark

Hi James & Computer Doc,

I am working on updating the FPGA 6809 design to include 6309 instructions.
I have bursts of enthusiasm from time to time and then I'm distracted by 
other things.
As I mentioned on the list before, I have a 6809 SoC on the XESS XuLA 
board, which is a 200K gate FPGA.
It includes the CPU, PS/2 keyboard interface, serial port & text VDU as 
well as a monitor ROM.
It has 1MB of RAM with Dynamic Address Translation.
It's a very tight fit in the FPGA. I'm not sure the 6309 design would fit.

I might write later. I have had a friend call in.

John.
