And another one...

This thing is truly awesome. SE accelerator that's supposed to go up to 50MHz (33MHz on the one I got) with onboard RAM (up to 16MB) as well as a video interface.
The accelerator part seems to be pretty standard, you can however set the speed multiplier via the DIP switches you see on there. Haven't seen that on any other accelerator yet. This is also the first accelerator I have seen that changes its clock speed once the control panel is loaded.
It will run at 8MHz or 16MHz at boot time (depending on switch settings) and shift up to 33MHz (or 16MHz if you want that) once the init has loaded.
The video portion consist of that one big FPGA and some video RAM. It does nothing until the video INIT loads and feeds the configuration bitstream into the FPGA.
It supports resolutions up to 1152*870 and a heckload of different displays from multiple vendors. Depending on how you connect the breakout board it supports TTL, ECL and analog (VGA style signaling) monitors.
Only the blue pin was fed with a signal on the 15 pin connector so I bridged that to the red and green pins to get a nice black and white image on my multisync TFT:

The whole setup feels super snappy. The external graphics are unbelievable fast as well - probably because they are directly hanging off the 32bit 030 bus on the accelerator.
Only drawback is that it is producing the same crackling audio issues that all of those SE/Plus accelerators seem to have. (and that I can't use an additional internal network interface card)
