257RB

The 257RB is a bug-fixed copy of Roman’s 257R board.

These PCBs were fixed as a project, by a developer who wishes to remain anonymous, and the board files supplied here.  

Since that time, the following has happened –  

• • • A batch of pcbs ordered from the revised files
    • Pcbs sent out to beta testers to 100% confirm the absence of bugs
    • EMS given the revised / fixed board files as a matter of courtesy

This is nothing greater than Roman / EMS’s board.   These boards are not currently for retail.
