Elliot Nunn 5b0f0cc134 Bring in CubeE sources
Resource forks are included only for .rsrc files. These are DeRezzed into their data fork. 'ckid' resources, from the Projector VCS, are not included.

The Tools directory, containing mostly junk, is also excluded.

;
; 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.
; ÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑ

; <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
