For some purposes, scavenging PALs and GALs might be useful. I have to say, I have difficulty throwing anything out.
If you're getting into desoldering, there are some connectors which might be worth keeping. I have a board with some SIMM sockets on which I thought might be useful one day.
Before I got into all this madness I was making circuits with copper tape and SMT. I have a SMT rework heatgun and mild to modest experience using it to remove and transplant IC's. My background is decidedly hodgepodge. I guess I just look at something like this winTV capture card and see SDRAM, audio ADC, crystals in just about every frequency thats useful for audio and video, some super crazy video I/O chip that manages to make it sound like a spaceship that can travel to 4th dimensions in the datasheet (a bit of oversell) etc and my heatgun finger gets itchy. But, at the end of the day, even though this board is from 2005, its still sporting some really hefty tech compared to what would normally be bumping uglies with a 6502... I guess I need to control my excitement.
More specifically to the topic however, would be more modern IC's that are commonly found in discarded tech in thriftshops. I guess I'm not really getting my intent of this across the best, but one feeling I get wading into this Olympic sized pool as a newbie is 'but there has to be a whole bunch of chips out there I can pull and use to streamline aspects of these builds'. Like, 'these soundcards had x IC on them so look out for this type of soundcard or toy' or 'check boards for this IC that is commonly used for decoding or whatever'. It just feels like there is a big blindspot in translation from newbies to the wisened masters in regards to widely applicable chips that are taken for granted perhaps but newbies overlook or don't know about? Hopefully this makes sense.
