Hello All. I'm new to this list and would like some advice on learning the inner
workings of vintage computers. I have some basic experience with electronics and some
simple measurement tools (multimeter, logic probe). So far, I've repaired a couple of
older machines (Kaypro's, Compaq portables) but this has amounted to swapping dead
hard or floppy drives, replacing dead batteries, etc. So here are my questions: (1) Is
there a "trainer" system good for learning about microcomputer design and
operation, and (2) would an oscilloscope be useful for this purpose, and if so, what Mhz
rating is needed to work on older machines? I've noticed the price is directly
proportional to this number! Thanks, John R.
