The PDP-10/X is a reimplementation of the PDP-10, with 512KW of memory, a line-frequency clock, an interface to an RS-232 terminal, and an interface to an ATA-2 disk, that I designed and built just for fun.

The FPGA PCB is a general-purpose FPGA board that I designed some time ago (but I tweaked it a little for use in the PDP-10/X). It is little more than a carrier for a XILINX SPARTAN-3E FPGA (XC3S500E-4) in a PQFP-208 package, along with the bypass capacitors, and the LDOs that generate the 2.5V (VDDAUX) and 1.2V (VDDINT) supplies. All of the I/O pins are powered by 3.3V.
