I grew up in the 80s with 8 bit computers and started collecting them in the 90s-2000s (when you could pick them up for free as long as you picked them up); I started repairing and extending them picking up video cards and old mobo's from dumps and 2nd hand markets. You can still buy boxes with mobo's from < 2000 which have usable things like memory for much older systems for next to nothing. Using a cheap digi scope, some bread boards, wire and analog electronics can get you quite far in playing around with slow (70-80s) digital components and hooking them up to others. On ebay they sell kits with old processors as I wouldn't recommend soldering apart 80s computers anymore => they are collectible and much appreciated in others or my museum. That said, it is a good start... If you can find a cheap one, find the schematic online and start checking out the components and measuring the signals. I am lucky to have many systems that have 74series logic + memory + cpu in them which is really easy to follow for any programmer. Most machines from that era won't have that unfortunately. If you cannot or will not risk that then simply buy a power supply, some packs of analog electronics, digi scope (few $100 one is enough), a box (2nd hand you can get them cheap) of different 74series, breadboard and a computer kit like [0] or [1] or [2] and start experimenting.
