I am looking for any info on A1000 hard drive controllers that people
are currently using with the Lucas board. If you have a setup that
works could you please e-mail me, let me know the controller you are
using and any "tricks" you used to get it to work. Thanks

Thanks > Scott Thompson (IH 6W-207), AT&T Bell Labs, Naperville, Il. 60566 Surprisingly enough, I have a Stardrive/Starboard controller working with my Lucas. Surprising since the Starboard was one of the first units found to have major problems with the Lucas board. I got mine to work only after TONS of hacks including: 1) Building the bus terminator. I used 2.2k pullups instead of 4.7k. 2) Splitting the two gates of U9 into two separate chips, allowing more combinations 3) Doing the DTACK latching fix posted by George Buce a few months back 4) Changing U8 to an LS? chip 5) Putting an F chip in half of U9 and an LS part in the other. Note that this was a LOT of work. A slower clock might help. I've heard that one of the faults of the Lucas board is that it doesn't keep the Address Strobe up as long as the 68000, which causes problems with some memory boards. (Alegra, for instance) A friend had to go down to 12MHz to get his to work. Hope this helps -vince

I have a friend who has yet to get his Lucas up and running. Thanks Monty

I also have a friend who is having fits with a LUCAS board. If documentation on any fixes is available any help or pointers would be very much appreciated. Thanks - Larry Stone (aren't student account names great ?)
