From: the.glenn0r on 12 Nov 2007 10:36 Thanks for the help. :) I'm going to bid on that ebay auction first. Hope I get it. If not I'll try some soldering .. The CMD Ramlink user manual I have is a 4th edition dated February 1993. And it clearly states that you must have a jumper cable on a C64 or C128D. Glenn

All I want it $5.00 + S&H for a TOTAL of $7 in the Continental US. Charles

Maurice purchased the right to manufacture and existings stocks from CMD in 2001. My Ramlink manual which is dated 1993 has instructions for attaching the timing clip. So the Rev.2 Ramlink obviously pre-dates Maurices purchasing of CMD. For the original poster, making a clip is easy. Go to almost any electronics store and buy a two pin header socket, a small length of thin guage hookup wire about 150mm long and an IC Clip. The two pin header only needs one pin to have the wire connected to it and on my Ramlink, it doesn't matter which one as they are connected together internally. So strip a bit of plastic off the hookup wire and expose the copper, slide inside one of the two metal header socket connectors and crimp with your favourite pair of pliers! The IC socket will likely have a similar crimping arrangement so do that for the other end of the wire. Simple as that, should cost you all of about $1.50 and five minutes of your time :) Mike |
