Perhaps an easier approach would be simply to download the Basic52 firmware and program it into the 8052-compatible microcontroller of your choice, handwired to a bit of perfboard about the size of a business card, together with a couple of 64KByte SRAMs. Together with a 64KB EPROM, which you download into the SRAM, then disable, it will allow lots of experimentation. When you get done, you may actually have a better feel for what to expect of this BASIC micro. The construction project could hardly take longer than an afternoon, and when you're done you'll have the baseline firmware at your disposal, though it might be a different verison. That will teach you a lot about firmware BASIC, even if it is a different version. I understand Intel's removed the BASIC52 stuff from their website, which means it won't be "out there" for too much longer. I'd recommend you find and download what you want, before it's gone.
