 This page lists the know errors on the gm5x5x5 PCBs.
+There are no known issues with the bulk order run (white pcbs), the following information is valid **only** for the prototype run (green pcbs).
+==== Bulk Order #1 (white PCBs, rev 1.0) ====
-==== Prototype Run ====
+=== #1 Silkscreen error (reported by dioioib) ===
+**Problem**: The silkscreen has the EEPROM the wrong way around - Pin 1 should be facing IC5.
+**Solution**: Stick the EEPROM in the other way around, with the "notch" facing IC5.
+==== Prototype Run (green PCBs) ====
 === #1 MIDI IO pins  ===

 **Problem**: The MIDI IO pins of the midi sockets (Pin 4 + 5) are switched.
-**Solution**: Either (1) sse the pin-headers if you use sockets that are not mounted on the pcb or (2) break the traces to pins 4 + 5 of the sockets and solder wires to them.
+**Solution**: Either (1) use the pin-headers if you use sockets that are not mounted on the pcb or (2) break the traces to pins 4 + 5 of the sockets and solder wires to them or (3) solder the midi sockets on the other side of the pcb.
+=== #2 MISSING TRACK  ===
+**Problem**: A track between D2 and R3 is missing.
