Hey List, I've got a really nifty device, a Siemens SIMpad SL4. It can do serial, PCMCIA, sound, has an 8.4 screen that does 800x600x16 and reads smart cards too. I want to put Plan 9 on this thing. Issues I have: I'm not familiar with the SA1110 architecture nor the Bitsy code, and I have a

I'm not familiar with the SA1110 architecture nor the Bitsy code, and I have a few questions about it. The Bitsy is an SA1100, if I'm not mistaken. There's not a great deal of difference between ARM processors. The bitsy has no floating point, but there is a floating poiunt emulator in Plan
