Computers have become vastly more complex than 8- and 16-bit machines of yesteryear, which had the advantage of being much simpler to program than their modern descendants. That's what led Konstantin Dimitrov to design the Ello 2M, a DIY retro computer that you can build yourself and use to design programs in BASIC and test out electronics.

Dimitrov is currently running a fundraising campaign for the Ello on CrowdSupply, where a $65 pledge will get you a basic, unassembled version of the computer. If you're willing to dish out $180, you can get a fully assembled Ello without a prototyping board when it ships this summer. And $240 gets you a complete system signed by Dimitrov himself. The entire project is also open-sourced on Github, so you can take a shot at ordering the various components and soldering the whole thing together yourself.
