I see the IC9 Rev 1.00 sticker there, but one is a Mark 2 empeg player. It is also happening on a Mark 2a player as well. Same pattern of behavior.

My original player (SN 080000404) QA Inspected 15/8/00 is a Mark 2 empeg player with a mainboard version stamped Issue 7 Rev. 1 (c) 2000 with that "IC9 Rev 1.00" sticker.

The second player (SN 010101705) QA Inspected 21/3/01 is a Mark2a RD100-20 RioCar player with a mainboard version identified as Issue 9 Rev. 2 (2000) with the IC9 chip sporting a sticker of "1.02".

Both were previously on a version of Hijack from 2002-2003 era.
