Pardon me for asking; I know little about the specifics of the S-100 standard but out of curiosity I have begun building a system using Monahan-design boards. I have the backplane finished except for an op-amp (which the USPS is sheltering in an undisclosed location) and have acquired a nice big case to house everything. Soon it will be time to provide power and that brings me to my question:
On the advice of the Google S100 group I will try to use switching power supplies instead of a linear supply, as was the custom back in the day. One Meanwell 7.5VDC 10A will provide 8 Volts (they assure me it can be "tweaked" up to 8V) and two Meanwell 15.5VDCs to provide plus and minus 16VDC. If I understand correctly they are yoked - + : - + to provide the 32V differential. (It's always possible I don't understand correctly, however.)
Is this a good idea? Are there any caveats about this plan? Is there a better solution?
Thanks for your suggestions.
