5000E
IIRC there are 3 CPU-controlled boost supplies and a set of shift register rings split across multiple boards
the shift reg rings are used to assign a pin to GND/Vdd1/2/3
I/O is done direct from the FPGA I/O pin with a resistor/diode clamp
for internal stuff, it was an Atmel ARM of some kind, a discrete USB device controller, an Xeltek "ASIC" and a Spartan 2 (IIRC)
I'm pretty sure the Xeltek ASIC was actually an OTP FPGA
(didn't do anything but basic LED control, bus multiplexing, and related stufs)
