yes normally plcc to dip but not the other way around. (cause who would ever need that) That said the plcc and dip pin out is not a straight 1 for 1 and that makes things a bit messy. That would not stop me from doing it though. That is making a frankenstein adapter. Regards Paul On Wed, May 7, 2

I've been looking for some kind of converter but, so far, I've come up empty. A converter to allow a PLCC44 to be used in place of a DIP is easy to find, but a converter to allow a DIP to be used in place of a PLCC44 is rare, at best. It also occurred to me that signal fidelity (crosstalk, r

The PLCC "plug" portion for an adapter can be had from at least one manufacturer for $36 US: http://www.ironwoodelectronics.com/catalog/Content/Drawings/PL-PLCC044-S-01FDwg.pdf Bob LaJeunesse > > From: Jason Rabel >To: time-nuts@febo.com >Sent: Wednesday, May

Wow at $155 or $125 + $65 for a stel replacement chip. Like the concept they have of allowing you to rewire the pins and frankly it would appear the $125 is a cleaner fit if it can be offset in the CS ref. But hey its not my project so will watch from the side lines. Paul WB8TSL On Wed, May 7,

Now that looks promising! The show-stopper problem with adapters like Jason found is size. There's only about 20 mm between the circuit board and the top of the case. I can imagine soldering this plug to a board that had either the DIP chip or a ribbon cable to connect it to an FPGA board.

It's starting to add up, isn't it? The only reason I'm considering it is because I was able to confirm that the Cs tube is alive. If I can get it working for a couple of hundred dollars and some time I think it's a worthwhile project and as Bert Kehren mentioned, I'm not the only one with a d

For interest, the prefix refers to the chemistry and the numbers describe the nominal dimensions in mm. So: ML = Manganese Lithium (rechargeable) (3V) MT = Manganese titanium lithium (rechargeable) (1.5V) and 621 = 6.8mm diam x 2.1mm thick. This system is reasonably consistent for coin cells f
