  • With a relatively small disk and without drastic measures the software Acorn wished to provide would not all fit. So, Acorn introduced a data compression scheme for its executable files. This squeezes program files to half size. When a compressed program is to be run, its compressed form is copied from the disk into memory, expanded to normal size and then run. (en)
dbp:quote
  • At that time people were beginning to adopt fairly complex memory controllers. These were things that did memory address translation through two layers of tables and they produced quite complex hardware. And I thought about this and decided I could find a much – a much simpler way of doing this. (en)
  • No doubt your UNIX will have the standard Bourne and C shells but will it have the latest Korn or Warwick shells? No to the last two. However, one of the reasons why people want those is because they can edit the command line if they make an error when keying in a command. The workstation will have the much loved BBC copy key facility. You can detach the text cursor from the graphics cursor and use it to copy a previous command, modifying it as you go. (en)
  • Two memory sizes are supported: 4 Mbyte , or 8 Mbyte . (en)
  • And unbeknown to me, I’d effectively just reinvented the very first memory management hardware that was developed for the Manchester Atlas machine, which again was based on associative memories. (en)
  • All the Archimedes podules are electrically compatible but need a Unix software driver to work with the R140. (en)
