I wrote a simple BASIC interpreter based on happy memories of the speccy, but to be honest I have more fun these days writing toy projects in z80 assembly.
I guess it's all about nostalgia either way though. The early experience in hacking games for infinite lives lead me to assembly, and z80 became x86. There was a lot in common removing anti-copying protection to getting infinite lives! Though modern games don't really appeal to me as much as Dizzy did, or the old-school fighting games.

I've had a lot of fun with Turbo Pascal over recent years. Simple single-board computers are easily available from tindie, etc, and even without that there are a lot of CP/M emulators out there.
I hacked up a simple emulator in golang for mac/linux/bsd - https://github.com/skx/cpmulator/ and there's a link to a set of binaries for turbo pascal, and instructions for using it available here:
https://github.com/skx/cpm-dist/tree/master/P
There's a highly related post on the front-page right now is about building your own Z80 computer, which would be ideal for running CP/M and thus Turbo Pascal!
