Is everything needed in the KUAL extension (second post)?

I wonder how hard to port this to the K1...

I found a 16GB class 10 microSD card (actual tested speed 16MB/s write, 19MB/s read), that works in my K1. Really hit or miss finding (non-antique) SDHC cards that fit the hard-coded assumptions in that decade-old mmc driver in the K1.

I will do a "time dd" speed test on this freshly formatted card (using the official "SD Association" formatter) in my K1 now. Then shrink the vfat and add ext3 and swap partitions to it (like I used on OpenWRT aeons ago). I wonder how long to fsck a 10GB jffs2 partition over that (apparently) SLOW K1 SDIO channel?

Anyway, first a terminal app, then Hercules360...

BTW, I had my own personal IBM 360/30 all to myself an entire summer (running in a hotter-than-Hades warehouse). There are cool stories to tell there -- it was a mish-mash of parts, but it got the job done. Can you belief an air-compressor and a punch-ball were integral components of that machine? The large inflated rubber "punch-ball" pressed the mylar punchcards (containing the microcode) against a large array of microswitches). I know because the official IBM service guy swapped in his own personal microcode punchcards whenever he showed up, to run his "proprietary" diagnostics, and he showed me how it all worked inside.

Anyway, "hand-toggled" 360 assembler in a K1 would be cool... ...if only for bragging rights.
