#Strange things do happen
2 messages in this thread
A few weeks ago I left a message describing some bizzare problems I was
having after I installed a new hard disk in my 2500. After much diagnostic
work and a few hints from here, I found out that I had an apparantly bad
ram chip on my A2620 board.
(Dealer complaint coming up…)
I took in it to the dealer, with instructions to find and replace the bad
chip. I left the damn thing there for 10 days while I went on holidays.
When I came back I called to see if it was ready. Not only was it not
ready, but they hadn't even started to look at it! He said they might start
that day. I called the next day, and he then told me they might get to it
by the end of the week. By then I had enough, I told him I would just take
it back, and fix it myself. When I picked it up, a different service techie
sympathized with my problems, and suggested the problem might be just a bad
solder job (that was the most common problem they found on customer
installed zips). I thanked him and decided to take a look when I got home.
Imagine my suprise when I checked the board and found that I had completely
missed one pin on one chip! The amazing thing is that the memory worked
fine for months! In retrospect, tho', it all made sense. My previous drive
was a ST506 type, and the drive cables went over the A2620 card. The SCSI
drive cable was right behind the area on the 2620 where the ram was. In
installing the cable, I must have just brushed the end of the chip,
breaking the contact. A little dab of solder, and everything works fine
now.
I just can't believe the chip for so long with the unsoldered pin. Weird.

Gene;
Surely you jest! Something like that should not surprise you at all. The
only surprise is that you found it (Murphy must be slipping) 🙂
I once new of a building contractor that was building a tract of homes.
The plumber that did the actual soldering of the copper tubing was sick one
day. The upshot is that one house was missed, however that house did pass
the leak test. After living in the house for over six months, a
significant "water hammer" occurred on the system and the flux that was
hold everything together "let go." The house was nearly destroyed. The
amazing thing was that the plumbing system actually held together
(appearently without weeping) for six months!
