Intel 8052 (and friends) minimum set up
Since these microcontrollers already have most everything baked into them (BASIC, RAM, ROM, Serial Ports)


What makes you think that these microcontrollers have BASIC built in?

There was one somewhat rare version of the 8052 that had a BASIC interpreter built in. If you have one of these, it will be clearly marked as a "P8052AH-BASIC", like this one:



These parts were neither standard nor common. The ROM in most other 8052s will contain an application-specific program that's unlikely to be useful to you.
