Manuals / jumper map for NEC FD1165 with G9NYB PCB

Secondly, the jumpers are scattered all over, and not in the places shown in the manual. I've got these jumpers on the board: RX -- 2x3 block labelled "0", "1", "2", "3" (set to 0) DX -- 2x3 block labelled "0", "1", "2", "3" (set to 0) VF -- wire link across "0" and centre pad VO -- wire link across "M" and centre pad RD -- 1x3 block labelled "1", "2" (set to 2) HD -- two pads, linked with wire RGT -- 1x3 block labelled "1", "2" (set to 1) AUT -- 1x3 block labelled "T", "S" (no jumper cap) DL -- 1x3 block labelled "1", "2" (set to 1) DR -- 1x3 block labelled "1", "2" (set to 1) DH -- 1x3 block labelled "1", "2" (set to 1) SC -- 1x3 block labelled "1", "2" (set to 1) SR -- three pads labelled "1", "2", open-circuit RG -- 1x3 block labelled "1", "2" (set to 1) The manual lists: DX -- Drive Select HL -- Head Load. 1=use Head Load input, 2=use Select input RX -- Radial Ready, 1=gated by drvsel, 2=always available SS -- Side Select. 1=use SIDESEL pin, 2=use DIRECTION pin PR -- Write Protect. PR1=inhibit recording when WP active, PR2=don't enforce WP FR -- FR1 = disable File Unsafe. FR2 = enable File Unsafe. DH/DL/DR -- Door Lock: DR -- DR1 = READY from controller enables Door Lock DL -- DL1 = (INUSE & DRVSEL) enables Door Lock DH -- DH1 = Lock Hold (generated by drive) enables Door Lock US -- In Use. Solder pads. US1=enable INUSE signal RD -- Read Data. RD1=source from read amp, RD2=source from VFO pulse shaper BU, BS -- Busy Lamp mode On during head load -- BU2,BS2 On during drive select -- BU2, BS1 On during In Use -- BU1, no BS jumper Which leaves: RX -- different implementation VF -- not listed in the manual VO HD RGT AUT SC SR RG And these jumpers which are in the manual but not on my drive: HL SS PR FR US BU, BS "Something isn't quite right..." -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
