Following advice of those on comp.sys.apple2, I made the 256 byte code 
non-relocatable and just made 8 slightly different copies in the ROM. A 
quick addition of three wires and this part works. I also wrote 
preliminary code for ProDOS support and it now shows up as a single 
drive in the slot that the card is in. Writing to it gives a write 
protect error, but unfortunately reading from it gives an I/O error. 
Also, since my prototype only has 64K I wrote this code to only support 
that one bank for now. Sorry, no photos or schematics yet, check back 
soon. Also, the e-mail address at the bottom of this page was incorrect 
until now.

I am currently working on a bootable ROM drive that is ProDOS 
compatible. So far I have a prototype built on a solderless breadboard 
that can have data sucessfully read off it into RAM. The boot ROM and 
ProDOS compatiblity are not implemented yet but I have a good idea how 
to make it work. I know there's not much info here, but check back in a 
couple weeks and I'll have pictures, schematics and such up. E-mail for 
more info if you'd like.
My Apple IIe setup
Here is my development hardware. Ok, so the 3.5" drive and mouse aren't 
connected but it looks good in the picture. I flew from Toronto to San 
Francisco in Feb. 1998 and then drove down to Los Gatos in a rental car 
to get Woz to sign my Apple IIe. Unfortunately I didn't get to meet 
'god' himself, but his accountant let me put the lid of the IIe on Woz's 
desk. I picked it up on my way back from San Diego a few days later. If 
you notice in the picture, the power light cover is missing. If anyone 
has a spare they can send me, please let me know. Thanks. Um... Click
