They might be out of stock, I suppose. If so, you can also get them from Electrospeed (www.electrospeed.com): 169.23.1415.421 50 ohm straight plug 252-38733D ?4.08 23.2415.421 50 ohm straight socket 252-38734A ?6.17 FMX 003 P102 75 ohm straight socket 252-3104J ?3.05 FMX 003 S102 75 ohm straight plug 252-3106A ?2.36 (I'd check those part numbers; S102 sounds like it should be a socket and P102 sounds like it should be a plug!) Electrospeed also sell Siemens inserts for DIN 41612 mixed-body connectors, which AFAIK are interchangable -- but the Siemens ones are (even) more expensive. You can also get them from RS (rswww.com) or Electromail: 485-164 RG178B/U straight plug ?4.16 485-170 RG174A/U straight plug ?4.57 485-186 RG178B/U straight socket ?4.84 485-192 RG174A/U straight socket ?3.89 You can get the cheap version from CPC (www.cpc.co.uk): CN04661 RG179B/U 75 ohm plug ?1.43 CN04662 RG178B/U 50 ohm plug ?1.43 CN04663 RG179B/U 75 ohm socket ?1.52 CN04664 RG178B/U 50 ohm socket ?1.52 You can get Sun-to-VGA adaptors (both genders), half-pitch 50 D plug (SCSI-2) to 50-pin 3-row D (which is probably what you called "weird oversized-D"), and 50-pin D to 50-pin D from Videk (www.videk.co.uk). -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York
