|
|
; Change History (most recent first):
|
|
;
|
|
; <SM13> 11/22/93 pdw Rolling in from <MCxx>.
|
|
; <MC5> 11/10/93 pdw Moved the event break stuff down to the bottom of RecordEvent.
|
|
; <MC4> 11/8/93 pdw Added better build-time control over tape_length and
|
|
; noncachability.
|
|
; <MC3> 11/5/93 pdw Series of attempts and re-attempts to fix various VM/FileShare
|
|
; problems.
|
|
; <SM12> 10/29/93 DCB <MC> roll-in.
|
|
; <MC2> 10/28/93 pdw Completely change how Record_Event stuff is done. Now it's back
|
|
; to front, among other things.
|
|
; <SM11> 10/14/93 pdw <MC> roll-in.
|
|
; <SM10> 9/9/93 pdw Lots of little changes. Name changes, temporary cache_bug
|
|
; stuff.
|
|
; <SM9> 7/17/93 pdw Minor change to StopRecordOnFull.
|
|
; <SM8> 7/8/93 pdw Adding RecordError stuff and StopRecordAtFull ability.
|
|
; <SM7> 6/29/93 pdw Changed where I get the event-debug trigger values. Used to be 0
|
|
; and 4, now it's $90 and $94 off SCSIGlobals.
|
|
; <SM6> 5/5/93 PW Converted names to meanies-friendly names. Updated with latest
|
|
; from Ludwig stuff.
|
|
; <LW5> 5/1/93 PW Changed mechanism for removing this routine when RECORD_ON==0.
|
|
; <LW4> 4/30/93 DCB Adding an RTS to the front of RecordEvent to prevent a crash in
|
|
; the unlikely event that someone calls it.
|
|
; <LW2> 3/3/93 PW Get rid of drop to int level 6.
|
|
; <SM3> 12/5/92 PW Added Break-at-event-match stuff.
|
|
; <SM2> 10/30/92 DCB Name Change for SCSI.a
