Hi, I've got an Apple-I that I'm going to take out of a box in the attic and try to set back up for showing/playing. I've seen several postings about what components "should" or "shouldn't" be in a vintage system. What's the feeling on replacing TTL chips, voltage regulators, etc? Should I scour the land to find "vintage" parts or can I buy stuff from regular electronics stores? (I don't actually KNOW that I need to replace anything yet, just asking) On a similar note: The Apple-I was a kit. Mine's just a bare board mounted inside a plain aluminum box. Was there ever a case made for these? Or did everyone just do what the guy who put mine together did? One last question: The Apple-I has on-board voltage regulators, diodes etc. to be used with a Do-it-yourself transformer setup. Can I just bypass all that and use a power supply from a PC with leads connected to the regulated side of things? The board uses the ususal +/-5V and +/-12V if I remember correctly... Thanks for any tips, Bjorn Eng
