MHO of what is reversible and what is non-reversible in this context goes something along the lines of: if you want to install a switch and you have to go even an extra mile to install it in the existing hole/opening that's reversible. If you cut or drill a new hole to install the switch that's non-reversible. Even if we all know that the hole can be plumbed. Similar applies to PCBs. When I design for example my ROM adapters, I make them so that one removes the ROM chips and plugs the adapter into the very same sockets. No trace-cutting, no fly-wires, etc. Changes are reversible [*]. Whenever you want to return to original state, you just pull the adapter out and put the chips back in. Obviously cut traces can be solder-connected back to function but in the context I'd call the modification/damage irreversible - it won't be the same as before when you solder it back together. And I don't even talk about things like drilling/cutting the boards, breaking it into pieces in order to fit into another casings, etc. Those are obviously irreversible in the context, even if one can theoretically try to reassemble things in the original case later on. -- SD! * - provided sockets were originally there. If not, installing sockets in a clean way, although "irreversible" in the context is still acceptable ;-) Message was sent through the cbm-hackers mailing listReceived on 2016-10-07 09:00:02
