That's what I thought. One more question. Since you used the Lo-Tech card, which way does it go in? I'm un-sure with regards to front and back of a standard PC, which is PIN 1. Hope the question makes sense. I don't want to insert it backwards.
So I deliberately use the Red Stripe at the end which will be closest to the back of the case and with the ISA-CF-IDE card the IDE header end of the card is the back - meaning it is closest to the rear of the case also. I made sure the red stripe of ribbon cable was installed at the end of the connector also. This will be Pin 1 for both connectors. See pic below:
This should work as shown but I havent been able to test it myself as my 1000 EX hasnt arrived yet. The EEPROM chips used in these are quite "fragile" and will die if the board is in the wrong way (the other chips wont care). So the easy test is to remove the EEPROM chip and see if the machine boots ok without it. if the board is in the wrong way you'll likely get some weirdness or errors - otherwise the Tandy should work just fine as tho the board isnt there.
btw, use a bench vice or large clamp to "install" the ribbon cables into the IDC termination block as they need a fair bit of pressure to install properly. Just dont go all in, ease on the force until it's really well terminated and the clamp part of the termination block sits nice and flat by itself.
Make sure you orient the cable as shown below - ie coming out of the PLUS Female header towards the ISA Slot, looping back over away from the ISA Slot and then coming top down into the ISA slot with the back 2 pins (end furthest away from red stripe) not connected. I'm 99% sure this will work as i've mapped it out in my head - it's copied from a couple of video's I've seen of similar adaptors so im fairly confident in the implementation.
