I recently acquired a Synertek MBC020 EXORbus single board computer, notably sporting a 6512 microprocessor. The 6512 is software compatibl...

It did not take long for me to realize that the virtual address jumper board for my MIKUL 6218 was not a great long-term soloution. It was ...

In my previous post on the MIKUL 6218 board, I mentioned that was using the lower 32K of address space on the CMS 9619 to swap in 16 banks o...

With the virtual address jumper for the MIKUL 6218 sorted , I still needed to simplify the address decoding and memory chip selects so that ...

A18 Addition I really want to use my two 512KiB SRAM chips on this board to maximize the usable RAM. Fortunately, the MIKUL 6218 has 32 pin...

I was recently able to trade one of my extra CMS 9619 SBCs for a CMS 9600A MPU (Thanks Joel!). This EXORbus processor card has very sim...

I haven't spent much time working on my CMS 9639 SBC because, unlike the CMS 9619 , it does not have any usable on-board RAM and does n...

After finding out that my CMS 9619 Advanced Single Board MicroComputer was having problems accessing the EXORbus , I tried some trouble shoo...

Update : Since this post I have figured out how to change the address map using a GAL IC. I recently posted some minor hardware modificati...

The EXORbus MULTI-PLANE backplane is now available on my Tindie Store !

Excited to see these EXORbus backplane cards arrive:

I just put in my first order for PCB fabrication today. After making some final modifications my ATX Powered EXORbus Backplane "MULTI-P...
