;
|

|
; <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<65>s latest version, and extracted out the
|
|||
|
; TERROR-ROM only stuff (to be INCLUDE<44>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 <20>Version<6F> from <20>RAMVersion<6F> 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<74>.
