I've got the mobo from the iMac 400 running in the 350 shell. It runs fine, it's got 256MB RAM and a 10GB drive. I partitioned it to have OS X sitting on the last 4.5GB (SL iMacs don't care about the 8.4GB thing like TLs and Beige G3s) and left the space between it and the Driver and Patch partitions marked as "Free Space". Then I installed OS X and ran all the updates. Deleted IE too. Then I loaded the Ubuntu 5.04 CD and tried to start from it. The iMac flat refused. No 'C" working here. Tried OF. boot cdrom gave me issues with XCOFF crap and stopped. Then I remembered a trick: boot OF, type mac-boot as if you wanted to boot OS X and hold down 'C' right after you press Return. Bingo! Booted right up from the CD. It seems sometimes OS X plays with the system and things don't want to boot as they should. This iMac would boot from the Ubuntu CD fine w/o OS X on the HDD. Odd.

PROBLEM:
I was hoping to be able to run the system at 16.67 MHz just like the OSI system. But just like the original Apple ][, the video has to read the memory interleaved with the processor. The 16.67 MHz, is 50 MHz / 3, with two 50 MHz cycles for the processor and one cycle for the memory. Preliminary testing of the APPLE ][ text video is not stable at 16.67 MHz. Even at 12.5 MHz (50 /4), the pixel clock and the CPU clock have to be syncronized.

Just a post - from my wifi Palm M500. I picked up a xircom wireless adapter and it.s pretty cool.
