Searle Grant's SBC and SD - current status

I have good news. I've implemented read sector, write sector and looks like things work. I haven't implemented reload CCP yet, but this is just a question of time and work - everything is clear for me, currently I have to reload CCP by full reload. Not so good news. TPA will be as low as 48K for the first public version. Only SD (up to 2GB) and MMC will be supported (MMC is unclear; I do not have one, but it should) - I mean no SDHC and SDXC support, bit I think at least SDHC will be added soon. The initial loader will be distributed in .HEX file to be load from terminal from $5000; ROM image - in the nearest future (but after SDHC code)
