I think it would be SUPER helpful for lots of guys like me if we could get a list going so we can at least get started...
Be a GREAT resource for new folks.

This is a good list of SRAM part numbers from many manufacturers:
https://arcarc.xmission.com/Web%20Archi ... /sram.html

286-386 typically have the same kinds of caps. 10Uf tantalum 25-50v, 0.1uf ceramic.

Keyboard fuses are often similar. 3A 125v axial.

Resistors would be totally up to the board design, although many are similar.

The most high wear/swappable components are the ones to keep.

I'm fairly new to the world of fixing old computers. Been upgrading, building, and around them since the 8080s. Now I'm trying to
learn how to learn how to work on these old machines and find that I'm drowning in an ocean of components. I diligently watch these great
Youtubers but they don't have lists published - they just say "let's see how many of those I have in stock, or I've gone a bunch around here, or
I have to remember to add that to my next order before I run out..."
I'd LOVE to have that "order" list these guys speak of. Especially for novices like me where buying one at a time is very tedious.

Does anyone know of a "basic" materials list I can order from Digikey or somewhere that can give me an assortment of
"typical" caps, resistors, etc.. for working on these old boards? Trying to figure out a list ahead of time for me is like developing
the parts for a Warp Drive... no idea what I need!
If I wait and order just what I see I need its a sloooow slog of ordering and waiting for parts.
Just basic essentials would be great.
I see Amazon has this "kits" that has cap and resistor assortments- but they are all 50v on the caps?

Thanks for ANY help you can suggest!

There are sellers on sites like ebay that sell them in sets.
Get one of them and then build up from there.
What you have to remember is most of us have been doing this for many years, which is where all the parts come from.

I recently repaired a spectrum analyser for a friend, the 3.5mm SMD audio connector got pulled off under the weight of the plug... In the mean time while it was on the shelf gathering dust he managed to knock some of the 2TY transisters.

A bag of 5 is like £2-£3.
Or you can buy an SMD practice kit and get 5 of them and a load of other little bits n bobs for £5.

Practice board sets are good in ways other than the intended SMDs.

When I recap I generally buy a couple more than I need, over the years it builds up.

Apart from that I cant give you a list because I dont have one. I just happened to have some spare 2TY transistors on my last little job.

What key words to use for searching these sets?

My experience is that you'll always end up having to get stuff for pretty much anything you want to fix. I've been doing this for quite a while now and always have been over-ordering (these components tend to be cheap compared to shipping) to build up a stock, but aside from caps for cap plague era (1000uF 10V, 1000uF 16V, 1500uF 10V, 1500uF 16C, 2200uF 16V in a few different sizes covers a lot) every single time there was at least something that I didn't have.

You can get kits for specific motherboards, but even very similar boards will have a different BOM, and as soon as you're doing different eras differences pile up - different voltage/speed, 74 logic chips, tantalum caps vs aluminium, different MOSFETs, different size & voltage (E)EPROMs etc etc.

Youtubers who always seem to have something lying around tend to be people who do a LOT of repair and have been hoarding for years (that's certainly the impression I get when I watch say Necroware). I doubt there's a shortcut to that.

dionb is right. You can't just pile-up a bunch of different electronic components. It just doesn't make sense, unless you're running an electronics repair shop.

There are some ready-made kits with components for sale on different i-net shops (including fleabay) - for example kits for complete electrolytic capacitors replacement on a certain model of valuable motherboards or PSUs, but so far I haven't had to look to buy anything like that.

To save on the shipping costs for orders from i-net electronic components shops, the best strategy for rare repairs, which I also use, is to assemble a bigger list of components for several motherboards, PSUs, videocards, etc.

If you're repairing electronic devices for a long time, even just as a hobby, you will accumulate some stock of components - from devices that can't be repaired at all, from leftover spare components when ordering more pieces than needed.

It depends on what it is youre looking for buddy.

"Capacitor set" or "resistor set" on ebay, once youre in the auction there are links to other similar items then follow the rabbit hole down?

I dont know what you do so its hard to help in any specific way.

I'll echo the above comments that trying to collect a bunch of random components before hand doesn't make a lot of sense. Same thing with generic component kits. I've bought a few of those in the past. I end up using one or two components from said kits while the rest collect dust.

I currently track specific components I need for different repair projects, then when I have enough to do a bulk order and save on shipping costs. I also always order extras of certain components. So if I'm ordering 40 of a specific type of capacitor, I might round it up to 50 or something especially if there are price breaks at different quantities.

Another source of components is to save old scrap parts (e.g. stuff that is non-repairable) that components can be salvaged from.

If you do this, over time you'll naturally build up a supply of useful components, especially if you find yourself working on similar hardware.
