Well, I recently got a hold of a handyboard from a
|friend of mine who swore it was "junk and didnt' work"
| After cleaning up some ugly looking solder joints on
|the board, it powered right up and began to work
|great. Well, when I went to screw it back down to the
|base, I think I shocked the bejesus out of it, because
|all the lights lit up. Now the board will power on, I
|get the standard bars, and it will RECIEVE the P-Code,
|but when I reset it, no IC.... Now I tested the power
|circuit for the Memory as per the assembly manual, and
|everythign checks out OK. I was wondering if there is
|anythign else I shoudl test before I drop a new Memory
|chip in, and also if that's my only resort, where do I
|get one from? Jameco, or Mouser, or another dealer?
|
|Thanks-

| Rmoving every chips except 62256 RAM and 74HC132, and try it again if it works. Besides the memory chip (62256), please also check the 74HC373 (under-neath the 62256 RAM).
