[comp.sys.amiga] A1000 daughterboard

Bruce_Eric_Bowers@cup.portal.com (03/06/89)

In an attempt to get my A1000 working with a CLTD hard drive, I ordered
new PAL chips from CLTD. I removed the J+K PALs, soldered in the new
sockets, and installed the new chips.

Now my A1000 will not power on even to the point of asking for Kickstart.
It gives me a light blue screen and the power light flashes.

I have a couple questions:

  1) Are there some common mistakes that I might check for, to alleviate
     this problem? The original PAL chips are probably no good, so putting
     them back in is not really an option. However, I was very careful
     not to overly heat the daughterboard or any other chips when I 
     installed the sockets. I also remelted all the new solder points
     to make sure I didn't have a cold solder joint. What else can I do?

  2) The service place near where I live is not exactly helpful. Over
     the phone, they said they probably couldn't diagnose the problem
     and would just replace the whole daughterboard (charging plenty,
     of course). Isn't there some way to fix the problem? If not, is a
     new daughterboard any more likely to allow my hard drive to work
     than my original board?

  3) They want to charge an outrageous price for a daughterboard. Is there
     anywhere I can get a new one myself, assuming my attempts to make 
     mine work fail? If not, is there anyone out there who wants to sell
     an A1000 cheap? (Especially if you have one with a bad internal
     drive, bad CPU, bad custom chips, etc that you couldn't sell as
     working). If so, please E-mail me info or give me a call at
     (301)-240-4179 days.

Thanks for any help or advice you can offer.

After Kwikstarts, Insiders, grounding Pals, munching traces
and other abusive activities, my A1000 daughterboard looks
like a war zone.  It's still chugging along, but does anyone
know of a source for a replacement?
