Narrative:
I was working sector 6 which overlies a portion of san juan approach airspace. Approach handed off a B727 to sector 8. The B727 was below my airspace. The sector 8 controller climbed the B727 into my airspace without issuing a pointout using 'look and go.' the sector 8 controller was relieved and the relieving controller believed that I was working the B727 and dropped the quick look of my sector. When I observed the 'I tag' of the B727 getting close to a C130 I forced the B727 data block to my scope and alerted the R8 controller to the conflict. The aircraft passed within about 1 1/2 mi and 500 ft vertically. In addition to the obvious factor of failing to follow procedure and issue a pointout, the mickey mouse earts equipment we have here at the cerap is a significant factor in general. The lack of a mode C intruder function and inability to force a pointout onto the receiving controller's pvd (instead a handoff is initiated then withdrawn, which results in a full data block appearing then disappearing) being specific factors.

Title: RPTED LOSS OF SEPARATION INVOLVING A CLBING ACR B727 AND A MIL C130 AT 15000 FT.
Narrative: I WAS WORKING SECTOR 6 WHICH OVERLIES A PORTION OF SAN JUAN APCH AIRSPACE. APCH HANDED OFF A B727 TO SECTOR 8. THE B727 WAS BELOW MY AIRSPACE. THE SECTOR 8 CTLR CLBED THE B727 INTO MY AIRSPACE WITHOUT ISSUING A POINTOUT USING 'LOOK AND GO.' THE SECTOR 8 CTLR WAS RELIEVED AND THE RELIEVING CTLR BELIEVED THAT I WAS WORKING THE B727 AND DROPPED THE QUICK LOOK OF MY SECTOR. WHEN I OBSERVED THE 'I TAG' OF THE B727 GETTING CLOSE TO A C130 I FORCED THE B727 DATA BLOCK TO MY SCOPE AND ALERTED THE R8 CTLR TO THE CONFLICT. THE ACFT PASSED WITHIN ABOUT 1 1/2 MI AND 500 FT VERTLY. IN ADDITION TO THE OBVIOUS FACTOR OF FAILING TO FOLLOW PROC AND ISSUE A POINTOUT, THE MICKEY MOUSE EARTS EQUIP WE HAVE HERE AT THE CERAP IS A SIGNIFICANT FACTOR IN GENERAL. THE LACK OF A MODE C INTRUDER FUNCTION AND INABILITY TO FORCE A POINTOUT ONTO THE RECEIVING CTLR'S PVD (INSTEAD A HDOF IS INITIATED THEN WITHDRAWN, WHICH RESULTS IN A FULL DATA BLOCK APPEARING THEN DISAPPEARING) BEING SPECIFIC FACTORS.
