| subject: | Flakey ZipChip 8000 |
I have an 8Mhz. ZipChip that's been out of service for a while due to general silliness and I decided to give it another shot today. This is one of the units with cheap, thin tin-plate pins that bend if you look at them too hard. After a heart-stopping experience bending two of them on the way into the motherboard, I decided to put it more or less permanently into a socket of its own for protection. About 15 minutes of aggravation, I realized that no amount of care in the world was going to get all 40 leads into a machine-pin socket :-(. I finally was able to seat it into a conventional tin-contact socket and plug that into the motherboard. The problem is that this thing won't start unless I press lightly with my thumb on the front right corner. At that point, it comes up and runs more or less reliably (although it does not reset from OA-Ctrl-Reset, I have to power cycle with my thumb on the chip). This thing may not even have one more round of insertion left before pins start breaking off, so I'm looking for advice on solving the intermittant problem and mounting it permanently in... something. What have folks done with these things to get around contact problems? Is there life after broken pins? I can almost imagine a circuit board with a pair of 20-pin headers and 40 holes offset a bit so I can solder the ZipChip on permanently. --- SBBSecho 2.12-Win32* Origin: Derby City Gateway (1:2320/0) SEEN-BY: 10/1 3 34/999 120/228 123/500 128/2 140/1 222/2 226/0 236/150 249/303 SEEN-BY: 250/306 261/20 38 100 1404 1406 1410 1418 266/1413 280/1027 320/119 SEEN-BY: 393/11 396/45 633/260 267 712/848 800/432 801/161 189 2222/700 SEEN-BY: 2320/100 105 200 2905/0 @PATH: 2320/0 100 261/38 633/260 267 |
