Very very early 42s?

My 42s has the serial number 2839A*****. I've read here in MoHPC, that the lowest known number is 2832, so the mine has only seven weeks more, hasn't it? This unit has not the COMB bug described here

Hi, Raul --

I own an older-design 42S (S/N 2939Snnnn) and have a newer-design 42S with recessed display made about a year later. The COMB/PERM bug appeared on all the earlier-"new" (1990-91) designs I tested, but not on my older one. I think a firmware revision coincided with the face changes.
