This resulted in having the same pin on more than one run!! Fortunately, the vendor pc program ignored one of the runs, thus failing to hook both runs inextricably together. the following pins may be affected: h9.5 one unnamed run to I13.15, ok pal output for map-write* h9.6 one unnamed run to I13.16, ok pal output for gc-we* h9.7 one unnamed run to i13.18, ok pal output for transp-we* h9.10 no connect transp-we* in fact comes out here. h9.11 no connect gc-we* in fact comes out here. h9.12 no connect map-write* in fact comes out here. h9.13 wirelist indicates both on BLM-A9 and MAP-WRITE* Is on BLM-A9. is not on MAP-WRITE* run. h9.14 wirelist indicates both on BLM-A8 and GC-WE* h9.15 wirelist indicates both on ALM-A9 and TRANSP-WE* ------------------------------------------------------------------------------- ECO#7 GROUND PD_MEMCTL AT SIP (TOO MUCH LOAD) GROUND C17B PIN 2. 6/1/88 ------------------------------------------------------------------------------- ECO#8 PARALLEL ENTRY COUNTER FOR HISTORY RAM SHOULD GO TO PULLUP CUT PIN 12 ON BOTH J23 AND J24, SHORT PIN TO PIN 14. ------------------------------------------------------------------------------- 6/22/88 MEM prevent traps attempting to happen when spy single stepping machine.
