; Change History (most recent first):
;
; <SM2> 6/14/93 kc Roll in Ludwig.
; <LW2> 3/24/93 mal Removed block xfer equ's that are now in ROMEqu.a.
; <1> 1/7/92 RB first checked in
; =============== Terror History ========================
;
; <4> 4/4/91 jmp Cleaned up conditional assembly stuff (i.e., started using
; ForRom instead of PadForOverPatch).
; <3> 2/25/91 jmp Rolled in Casey’s latest version, and extracted out the
; TERROR-ROM only stuff (to be INCLUDE’d from ComVideoEqu.a).
; <2> 1/7/91 jmp Prior to my last full build and checking this file in, I somehow
; deleted the word “Version” from “RAMVersion” in this file
; causing the TERROR build to break. Oops. I guess I’ll do builds
; AFTER I check things back in next time. Sorry BG.
; <1> 1/6/91 jmp Checked into TERROR ROM for first time.
; <0> 11/19/90 jmp Formatted for use with TERROR ROM (as opposed to a
; declaration ROM), removed duplicate equates, etc….
