Well I've spent a lot of time finishing off the PCB layout for the FLASH SIMM.
I've attached the schematic in PDF format if anyone is interested and able to look at it. Before I send away to make it there are a couple of things to do:
1. Check the schematic and footprints
2. Write some CPLD code to check that the design can be made (this should not be a problem)
3. Write some FPGA code to check that the design can be made (this will easily fit)
4. I already have a design for a SIMM reader. I need to make some of these to explore the format of existing SIMMs.�
Then I can make some of the FLASH SIMMs and start working on them.
