Edge connector...

I made one or two of these myself. I recomend using something like an x-acto razor saw to do the slicing. Leave the cut end a little long and sand it down to keep the pin spacing correct at the joint.
 If you're salvaging the ISA connectors off an old motherboard, one way to do it is to use a heat gun or torch on the solder side. Use vicegrips on connector, and put an old isa card in the slot to keep from crushing it. Ideally do it outside with the motherboard in a vice. :-)

You could also call up www.digikey.com and ask for a S1504-ND
:-) 10 bucks.

I had one of the commerial ZorroII expansion boxes on my 1000. It worked well, even with a loaded 2058 Ram card and a SCSI card. I did the grounding mods in the 1000, and ran a ground out into the into the box. No bus noise problems

As for bus noise on the a1000, would a high speed cmos buffer, maybe a schmitt help with that?

It probably would help to use those better chips. My 1000 did autoboot. I put the Kwikstart board in there. Handy, since the internal floppy died and I couldn't load the kickstart disk anymore. :-)

Do you have any details on the commercially made Zorro2 Expansion?

Remember, this was for the 1000, not the 500. There were more available for the 500. The one I owned had 2 Zorro slots, and a passthru. There was room inside for a 3.5" hard drive and an optional power supply. It was made by some outfit called "Phoenix".  On second thought, I believe the box was made by Micro R&D, the folks who made the Bigfoot power supply. The box was called "Phoenix"
