Key Tronic foam and foil tactile (two-dot unbranded w/cutouts) A079357 mousefan.telcontar.net Terribly confusing. The case is marked “10 6 87”, while the rear label is marked “33-08-89” (week 33 of 1989 was mid-August). The PCB is labelled “3091” followed by a sticker reading “201”, but I am discounting that as being a date for now. Unfortunately there is no picture of the ICs to help determine the most likely date.
