- I love 6809 as well as 68008. We cannot compare which one is better,
- the 6809 has some addressing mode you cannot find in 68000. The 6809 is
- definitely nice. Programming 68008 is not changing the 6809's code
- somewhat, it shall be a different thing. But if you really need a
- surface mount CPU, I think you do not have much choice -- use 68008
- instead of 6809.
-
- What is your new design? I had designed and routed a 6"X4"(Europe card
- profile) 68008 CPU board 2 years ago. It has 2 serial ports, battery
- backed static RAM and a 8bit address + 8bit data bus + 7 interrupt lines
- to outside world. With 8 sockets for 256K/1M bits SRAM/EPROM. It is
- intended for use on a 10 slots (8bit A & D bus) backplane.
-
- Currently, I am soldering the second card (also designed and routed by
- me) -- a graphics card used with the 68008 CPU. It employs the TMS34010
- as graphics processor, 512KB VRAM, 2MB DRAM, a 16/4096 palette and a
- keyboard interface to IBM PC keyboard.
