Need contact information for dkdkk

I tend to confuse Bletchley Park with the CCS, so I might be moaning about the wrong lot. But (IIRC) the CCS's method of using its members' knowedge leaves a lot to be desired. IIRC, the membership form asks for up to 4 computers that you have experience of. I had a serious problem with filling in that section. Should I list 4 machines that were relatively common, on the grounds that I'd then get to do something. Or should I list 4 rare machines, which I knew somewhat less about, on the grounds that I might well be the only person to have any knowledge of them at all? There is another problem, best illustrated by an example... Suppose you have a non-working HP9810 calculator (well, it's almost a computer :-)). You have a choice of 2 repairers. A) Worked ofr HP as a service engineer for many years. He's got the official service manual (which is a boardswapper guide), and can follow the instructions which are basically to replace all the plug-in PCBs until it starts working again. The fact that you can't get replacement boards any more is another matter... B) Has never worked for HP or any other computer company. But he was given a broken 9810 a few years back and spent a couple of months working out how to repair it. This guy can connect a logic analyser to an undocumented internal connector and trace the CPU microcode. He's got his own microcode listings and can thus tell just what the darn thing is doing. Now, who do you pick? There's also the problem that somebody having no experience of <foo>, but who is generally clueful about similar stuff might well be more use than somebody who's had a few months user-level experience of <foo>, but who has never gone further on any machine. -tony
