Thanks 😀 If you could hack up your vector symbol you did in eagle that would once again be largely appreciated - the logo shown above is just a 5 minute photoshop hack with the G build from the letters O and U 😉 In case it helps, I identified the font used for the GUS part as "Univers Exp" or "Nimbus Sans Extended Regular" (prefer the first because it has a simpler G).

Have a look at this wonderful thread by jwt27: Short on ISA slots? Try this.
Maybe you could split up the header in blocks just like he did for his ISA-header PCB? This way we could later use ARGUS as a universal ISA riser.
That's basically what I did yesterday 😀 That way one could either design a daughterboard for the ARGUS (i.e. with SoundBlaster compatible hardware) or use it instead of the $25 riser card. The 64 pin connector will have to be cut short of 2 pins tho (ISA8 is 62 pins) - not a big issue tho, just leave 2 pins unconnected.

If incorporated, it would make up for the -5V line that is absent in all modern power supplies, but still needed if a LAPC-I or CT1920 is installed. Of course, if you decide to implement it on the PCB, then a jumper should be put there as well (for people that still use PSUs with -5V). All this could be made just as an option for those who need it - just leaving it all unsoldered in the final product.
Personally I would be very grateful if you decide to implement this 😀 I hope I'm not alone.
Works for me 😀 Especially since that area of the ARGUS PCB is quite blank since I moved parts around a bit for implementing the headers. Actually considered making a -5V supply a small side project of it's own, but yeah - totally makes sense to include it as an option. Even when the card actually derives it's own -5V supply from the -12V rail.
Thanks for the suggestions 😀
