Does anyone know where you can get a schematic for one of these

http://www.reactivemicro.com/product_info.php?cPath=1_29&products_id=110

I would like to make one. They have the .bin image for download, but I haven't found the schematic anywhere. I can burn my own eproms, so that is not a problem. I really enjoy making simple things like this, and it looks like it would be useful for me since I have the CFFA3000. It isn't that I don't want to support vendors of Apple products, I would just like to try it. If I can't find the schematics, I might buy one. Is Reactive Micro still selling products? I seem to remember something about them shutting down for awhile.

Thanks

Last time I contacted Reactive Micro they were not selling, but I hope they open again, they have great products!
Good Luck

Drop Henry an e-mail anyway. Sometimes he'll get something out of storage and ship it. Besides, it's good for him to hear from people that miss ReactiveMicro.

Re: Dual CF Slot Scan Boot Adapter

I would really like to buy or make one of these, so i could put my CFFA3000 in slot 1, and floppy controller in slot 6 or 7, and boot to either with just the flick of a switch. Right now, when I boot up, from floppy, it is normal. If I want to boot from the CFFA, I turn the machine on, hit CTRL-RESET, then type PR#6 to hit the CFFA. It works, but would be nice to just flip a switch. Besides, I get enjoyment out of doing the mods, and that is what it is all about. Thanks.

Re: Dual CF Slot Scan Boot Adapter

LittleJohn Systems made a neat little card. It fits into Slot 6 or 7 Vertically and has two Horizontal Slots for cards with a switch.
The switch has a hole in it.
I placed on into a IIe and using a large paperclip, bent to fit, run through the hole and out the back of the IIe. All I have to do is reach behind the IIe and Push or Pull the paper clip.

Works like a champ.

The only thing is that he was selling them through Reactive.

Works well running two CFFA Cards, or a CFFA Card and a Disk Drive Card.

Its in one of my computers around here. Hmmm. I need to find that.

Re: Dual CF Slot Scan Boot Adapter

What Schematics?
The original CF is a 27128 Eprom and the replacement a 27256 Eprom
And this is the "secret" switching between the 2 images:

Thanks for the link. It looks like all I need is a 28 pin socket, a switch, and a 10K resistor. I appreciate it.

Re: Dual CF Slot Scan Boot Adapter

Thanks again for the link. I rummaged through my parts drawers, found the parts, burned the eprom, and it works fine. I ran two wires outside the case through the side vent slots, and will hook it up to a switch. Right now, I am just using an alligator clip lead to short the wires. It doesn't have the nice PC board, but it doesn't even look half bad. Works like a charm. Thanks again!
