I recently picked up an early original Macintosh II which among other things came equipped with a SiClone Si3033 accelerator board. It's a two-part system with what looks to be a mostly passive board that houses the original 68020 and FPU and a second board that contains the 68030 and FPU. The first night I had the Mac II running beautifully; the next night - I went to power it up and I got no boot bong, but the system still booted normally until about 30 minutes later when it had hard locked. I did a quick power cycle and tried bringing it back up but this time I got no boot bong and no display. I could feel the 030 getting warm, but it wasn't actually booting the machine. Pulling the 030 half off the board and just leaving it with the 020 also resulted in the same issue; only when I pulled the 68020 and FPU off the SiClone and stuck them back directly into the II's motherboard could I get it to boot again.
Anyone got any clues as to what could be going on here?
