!!!Mounting Tension: [BBC]
The next model was the Acorn [BBC]. Because they were British, schools in the UK used the [BBC] computers. Some schools in NewZealand followed suit. The [BBC] Model B also had a 6502 processor. This was probably mid-to-late 80's to early 90's.
-The BBC's graphics and sound hardware were well accessible under [BBC] [BASIC] with the powerful plot and envelope command, respectively. They were both far ahead of anything any other computer in this class had to offer. What really set the [BBC] apart was the modularity of its operating system and its use of interrupts. There was a MOS for all the basic functions like video graphics, buffered keyboard input, vectored interrupts, buffered sound. 16k ROMs were available to accomodate networking routines and many different programming languages ([BASIC], LOGO, [Pascal], [Forth], you name it).

+[1] Actually, the electron had the envelope command as well (it also ran BBC BASIC). The envelope command took 14 parameters, and I must have spent many hundreds of hours playing with the parameters to see what effect it had on the resulting sound, without ever figuring out what each parameter did :) Obviously it wasn't just a single pitch; one command could rise and fall multiple times with varying loudness...
