EP2C5-DB-TH FPGA card

P1743-720PX.jpg

I love Grant Searle's Multicomp project. It lets you easily create 6502, Z80, 6809 Retrocomputers of the late 1970s era. This card provides all of the connections needed.

Grant's original design used an EP2 and that's exactly what this cards USES. Note that's not compatible with the latest version of Altera/Intel Quartus but you can download older Quartus II versions like 13.1 SP1. Just make sure it supports the Cyclone II family of FPGAs.

Other (Newer, Bigger) Versions of this card

We also have two EP4 versions of this card for sale on Tindie (bare boards, you populate).
