Hi Multicomp09 Enthusiasts,

I have a version of NitrOS9 6809 L2 v03.00.00 for the Coco 3 that Gary Becker adapted to boot from an SDHC Card on his Coco3 FPGA design for the Altera
Terasic DE1 FPGA Board. Many features of the Coco 3 are implemented on this platform. However the one thing I have done inspired by a fellow Coco
Community member that I think you may be interested in is I adapted the device descriptors to make it possible to create 4 - 1GB partitions on an 8GB
SDHC card. If you are interested in how I did this, I had created a setup guide for other Coco3FPGA users for adapting a freshly compiled NitrOS9 boot
image file to run on the Coco3FPGA platform with 4 - 1GB partitions that you could adapt for the Multicomp09 that I would be most happy to share with you.

Hmmm, that reminds me, I need to check the online storage situation on my Multicomp09 boards. I don't remember if they can even use the larger SDHC
cards that 4 - 1GB partitions would require. The Multicomp09 was originally designed to use 2GB SD cards. I'll need to see if the Multicomp09 was ever
upgraded to use the larger SDHC cards. If the Multicomp09 can use larger SDHC cards, I think I just might have to upgrade the NitrOS9 running
on my Multicomp09s to utilize this enlarged online storage system.

Neal, do you remember if the compiled VHDL source code for the Multicomp09 can read SDHC cards?
