"Market" for old macs?

True.... If my car [1] broke down somewhere, then yes, I would probably misuse tools to get home. Things like using a flat-blade screwdriver to fit an open-ended spanenr that's too large for the nut, using a Mole Wrench (Vise Grips to you, I think) in place of a spanner, using a hammer ratehr than a puller,using a credit card as a feeler gauge for the spark plug gaps (it's about right for most engines) and so on. But I certainly don't do that sort of thing if I can get the right tools easily. [1] OK, I don't have a car (or even know how to drive), but you get the point. You can drive a pozidrive screw with a phillips driver and vice versa. But if you try that on anything I own, or with my tools, you will regret it. It does damage to both the tool and the screw. I basically consider there are 4 cases : 1) The right tool is in the toolbox. Get up and use it!. There is then no excuse for using the wrong tool.. 2) The right tool is easily available and at an affordable price. Unless the job is an emergency (which few hobby repairs to classic computers are), then it is nearly always best to wait until you've got the tool 3) The right tool is unvailable or unaffordable, but there is a kludge that will work with minimal damage. In which case it may be worth trying that kludge. Sometimes the workaround is as good as the original, it just takes longer (e.g. using a measuring device to set the position of something, rather than an accurate lenght 'spacer' from the special toolkit. 4) The right tool is unavailable or unaffordable, and it is essential. Then you have to make a substitute tool. Often 'special tools' can be made in a good home workshop. IMHO, a true craftsman, given the need for a long TX15 driver, and being unable to get one, would make the right form cutter, make a dividing head (heck, it's division by 6, one of the easiests ones to lay out by simple geometery if you had to do it that way), and would mill the darn thing -tony
