Ok, so the power adapter has arrived and after a bit of wailing and gnashing of teeth I have the driver installed.
1. The power adapter I ordered from Mouser is wired correctly for the usb2isa adapter.
2. The documentation is wrong on one of the power selection jumpers. Says it is supposed to be 2-3 (default) to use the external power adapter but it is supposed to be on 1-2. Bleh
3. You have to disable driver signing and to do this you also have to disable secure boot in the BIOS. No mention of having to do this in the manual but it does mention that the driver isn't signed... or rather the installer isn't signed. The driver it uses is a Microsoft one... winusb
After that the driver will install just fine.
Then you have to load the enumerator application by running it as admin. Once it comes up it freezes for a bit while it initializes.
I haven't actually tried it with an ISA card yet but it looks like it will auto detect resources... at least on non-pnp cards. I think you may have to manually add the needed resources for pnp cards from the looks of it but not 100% sure.
There are a couple of options once it initializes... for the type of software that will be controlling it... DOS/Win3.1 or Application based. If you choose application based it launches DOSBOX 0.74 (their included version).
For resources you can manually add I/O ports, memory addresses, IRQs (3,4,5,6,7,9,10,11,12,14,15) and DMA (0,1,2,3,5,6,7)
It says to add resources only if they are not detected by the enumerator.
You can change the Rd/Wr time. Default is 250ns. Options range from 41ns to 2333ns.
You can enable Direct app. I/O access if running Windows 2000/xp/Vista.
So it looks like pretty much anything should work with it. I will try to do actual testing tomorrow.
