; Change History (most recent first):
;
; <K3> 9/8/93 ag a new set of values for the backlight table. this should
; increase the range on both the top and bottom ends.
; <K2> 8/13/93 ag changed hardwareequ.a to hardwareprivateequ.a.
; <1> 7/27/93 ag first checked in
; <H12> 3/11/93 RLE another pass at the Escher backlighting table
; <H11> 2/26/93 RLE split a new backlight table off for Escher since the displays
; are just a wee bit different
; <H10> 1/21/93 RLE add support for Escher
; <H9> 7/13/92 SWC Yet another pass at the DBLite table. Deja vu, eh?
; <H8> 6/30/92 ag Added cpu info tables for cpu dependent information.
; <H7> 5/7/92 ag Changed the structure of the backlight tables. Included in the
; tables are a header which indicates the minimun and maximum
; values.
; <H6> 4/10/92 SWC Yet another pass at the DBLite table.
; <H5> 3/4/92 SWC Next pass at the DBLite table.
; <H4> 2/12/92 SWC Changed the DB-Lite table limits to have a narrower range of
; values.
; <H3> 9/10/91 SWC Changed the DB-Lite table to have a span of 0..127 instead of
; 0..255 since the backlight values don't go that high.
; <H2> 8/26/91 SWC Added a PWM lookup table for DB-Lite.
; ———————————————————————————————————————————————————————————————————————————————————————
; Pre-HORROR ROM comments begin here.
; ———————————————————————————————————————————————————————————————————————————————————————
; <5> 7/8/91 ag added lookup table for ashai added name constant for gestalt
; lookup
; <4> 6/24/91 ag added new lookup table for PWM low voltage operation.
; <3> 6/11/91 ag added new table for low power scaling.
; <2> 4/2/91 ag added table lookup for PWM
; <1> 1/23/91 ag first checked in
