Of course after finding that #BBCMaster video again, YouTube thinks that I should see someone who was not even yet born in the 20th century going on about the woes of typing in PETSCII copied from computer magazine listings. (-:

It's not in fact an experience that I can relate to. I loaded/saved PET programs from/to tape, and never had a C64.

Come to think of it; you don't see many of the #retrocomputing crowd using #cassettes, do you?

Retrocomputers! You haven't had the complete experience until you've accidentally unplugged the headphone jack and listened to the code. No, it doesn't sound like modem handshaking.

Aha! Found it! I'd been looking for this. Recommended once by YouTube, and then lost.

… on GEM
… on DR-DOS
… on an 8086 PC emulator
… on a Raspberry Pi
… running as a second processor using a BBC Master 128 for I/O.

There's a follow-up re-hash video by @WiFiSheep that explains the tokenization problem with the CIRCLE statement.

Of the many people who have run #Elite on a Pi second processor, none seem to have thought about switching to the PDP-11 emulation and trying to run some early Unix. But seeing DR-DOS on a BBC Master is pretty wild.

Pretty amazing that the #NES, #AppleII, #BBCMaster, and #BBCMasterCompact versions of the seminal 3-D space trading and combat video game #Elite all fundamentally base their source code from the #Commodore64 port. (All pre-dated by the #BBCMicro and #AcornElectron versions, of course.)

A BBC Master video from me, telling the story of how I got a 6502 second processor working, all for one particular reason.

You’ll need to watch the video to find out what that reason was.
