Something to look at. Some vendors of 2n3906/04 and other small single transistors have different pin orientation for their parts in TO92 case. C and E are swaped. Look at the vendors data sheet for your part, not a generic one.

A peek with a magnifine glass shows the squareRich,I'm not even sure what version of the board I have. However I'm pretty
I don't know if version 2 of the backplane suffers from the same error.

Subject: Re: [N8VEM-S100:4159] Re: S-100 Bus Extender and S-100 Bus Terminator Boards Have Arrived<8slotQ1Q2.png>I was looking at the S-100 18 slot backplane and saw notes on the incorrect
footprint on transistor Q1.
I have the 8 slot version and have no such notes on Q1. When I pull up the docs from
the wiki I see that Q1 suffers from the same error.
Can those of you that have the 8 slot board running confirm this board suffers from the same error?
Are any 18 slots boards available?
Thank you.

Please let me know if you'd like any. The usual price of $20 each plus $5.95 shipping in the US. If you're outside the US then I'lllet you know the actual postage once I have the package set up and weighed.
If you ordered other boards and want them to ship together that's no problem either.
Thank you!
