Wow! How did you do that? Just from the schematics, or are you the
chap that bought the kit of parts from me at Wakefield? I'm
impressed you managed to build it 12 hours before I uploaded the
assembly instructions! (I note from the headers that this message
appears to have been posted late last night, just as I managed to
stagger home and into bed :))

Have you ensured:
 
Drive set as:
  Master (not slave)
  C (not D)
  0 (not 1)
  A (not B)
*UNPLUG 13 to disable onboard ADFS, replacement ADFS ROM inserted
*CONFIGURE HARD to enable hard drive access

I've some test programs. I'll ensure they're findable on the
website. If you continue to have problems, email me.
