moar 10PRINT nonsense

10 Print CHR$(205.5+RND(1)): Goto 10

but this still owns it:

10 PRINT CHR$(199+2*RND);: GOTO 10

I found I can get this to preload in an emulator, but you still have to type RUN and hit return. See, look: http://scruss.com/cpc/6128s.html?stardoj.dsk/10%20PRINT%20CHR$(199+2*RND);:%20GOTO%2010

Rob Manuel’s British Council Tile / Bus Fabric Sim

Rob’s British Council Tile / Bus Fabric Sim — described here: Amstrad BASIC that approximates the tiling schemes that a local council might have used for a municipal building in the 1970s — is a joy. So few colours!

No, really: this *was* the seat pattern on Western SMT buses circa 1979

Because I care (and don’t if you don’t), here’s the Locomotive BASIC source, lovingly typed into the Caprice32 emulator then extracted as text using iDsk:

And if you really care, here’s an emulator snapshot — BritishCouncilTileSim.zip

Update: I modified the code slightly (essentially, all INT(RND*n) to RND MOD n) so it would compile with Hisoft Turbo Basic. It works! It’s faster!
