There is a (UK-based) listing on eBay selling what it claims to be MC68B29 MMUs (for use with the 6809) in tubes of 9. [link] I have already bought some but not used them yet. According to the datasheet you can use up to 8 in one system.... more »

6809 IO board -- need information
|
| |
Hi All! I would like to design an IO mezzanine board for the N8VEM 6809 host processor board. The intent is to add enough IO so that the 6809 host processor can be used as a stand alone system. It would still have its ECB interface to access the rest of the N8VEM system but could operate on its own more independently.... more »

|
| |
Hi! I have several N8VEM 6809 host processor board PCBs available. Recently one of the N8VEM builders built one of the units and got it working. It requires a simple cut and jumper modification to fix an error on the PCB layout but otherwise seems to work fine. The board currently runs a modified version of the Motorola minibug software for... more »

M6809E and Multiprocessing
|
| |
My memory is quite foggy on this but I remember an article, maybe in Byte magazine, about designing a multiprocessing using the MC6809E. I think the hook of the article was that it made available the necessary external timing signals to build a system with four processors and a suggested application was for matrices. Does anybody else remember the... more »
