VIC20 SERIAL# ASSY OTHER MARKINGS V002115 USA 324003 1981 R-4SB brown & gold label, PET keyboard V174631 USA 324003 1981 TP-508HB brown & gold label P1236655 USA 324003 1981 KU-14194HB P1654845 USA 324003 1981 W-18 94HB-TN The first two had the original keyboard which was a PET keyboard with VIC20 keytops, however there were only enough good parts to get one keyboard working. They all have the two prong power connector. If there is a real difference in the two kinds of two prong power connector, the assembly number of the boards should be different. You did not give the assembly number of your VIC20 boards. It is on the right front of the board, just under the edge of the large heat sink.

They do not appear to be date codes. They are part of the original markings on the boards and so all boards from the same production batch must have the same markings. - This message was sent through the cbm-hackers mailing list.
