John,
What a very nice collection of S-100 boards! It's impressive to see so many boards together. Now you just need a 100 slot motherboard to plug them in all that the same time (and a transformer the size of a car). :)Josh From: mon...@vitasoft.org To: n8vem...@googlegroups.com Subject: RE: [N8VEM-S100:5355] Re: A New S100 Video MSX compatible board. Date: Fri, 10 Oct 2014 10:16:06 -0700 I will see when I do the step by step build write-up of this board Steven if I can include a BOM. Since I now have gotten KiCAD working I think it has a BOM list capability. As to vendors and part numbers on boards, unfortunately I simply don’t have the time to do this, perhaps somebody else could chip in. These days I’m doing typically 3-4 new boards a month here, mostly prototypes, I simply stock up on batches of common components and IC’s and draw from that. Attached is a picture of my main “work in progress” table! The boxes (there are others), contain the most commonly used IC’s.
I actually find Jameco to be the best for most parts, they are local here, failing them I usually go with Mouser. I can never seem to find anything on the Digikey web site. The only overseas vendor I trust is UTSource. I avoid eBay except for components (connectors etc.). John

Very interesting board but my concern was difficult to obtain components. It will be much nice to provide BOM. This will help to locate the components available for sale. Don Caprio created excellent BOM that make easier to find the components quickly.
I discouraged some vendors such as Newark, Allied, Mouser and Digi-key tend overcharge for shipping. Sometimes they impose with handling fee and sometime they refuse to sell just one component (i.e. resistors). It was not friendly for hobbyist but okay for large corporation. I checked other vendors and most of them did not have in stock that drive hobbyist into frustration included varies of prices. eBay tend to create overcharge for components. I searched some components for my Ithaca Intersystems cloned project. Some sellers want to sell over 55 dollars for just one chip while I found other vendor sell for 79 cents if purchase 10 pieces. I strongly believe eBay components are closer 80 percent were not function or relabeled.
I wonder if there are some other way to purchase large volume of components for S-100 hobbyist as Mr. Caprio posted on eBay with "kit". I assume this will help to build the board much quicker like old days with Heathkit.
Any better ideas???
