New pcb design for S-100 prototype board available

Hi Thanks for the positive feed back. Needless to say like all standards S100 had different versions. For example the Northstar Horizion had some active components on the mother board. However if we look at a basic passive (other than power) back plane. What are the potential problems? Firstly the connectors are they available? They had two rows of fifty connections. Spacing pin to pin .125in. Mother board was thicker than the usual 1/16 in for rigidity possibily 3/32 in. Card guides pretty standard but how high? Then the metalwork supporting the card guides. Possible Parts List 1. Double sided S100 motherboard (Say twelve slots) 2. Aluminium base plate drilled for backplane and card guide supports. 3. Twelve double sided 2x50 edge connectors. 4. Card guide support frame. 5. Twenty four card guides. 6. Nuts, bolts and screws etc. Rod Smallwood -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Dan Sent: 03 June 2007 12:59 To: On-Topic and Off-Topic Posts Subject: Re: New pcb design for S-100 prototype board available Rod, I see what you mean. I'm just starting off small right now since it's mainly a hobby. It's mostly to support the existing vintage computers out there. I really don't know what the demand there is for a new S-100 chassis. I suppose that might be a good kit to build with the right parts. I can look into this. =Dan [ My Corner of Cyberspace http://ragooman.home.comcast.net/ ] Rod Smallwood wrote: with back plane and PSU.
