L/+UTILIT

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

SORRY for the radio silence - busy doing my final year project in York.
Any readers with web sites, please ensure that, if you're linked to my
York address, you change to http://www.sprow.co.uk/bbc
   On this EUG disk, you will find two utilities from me: LISTO and an
update to the RAM filing system which was published in EUG #50. Inspired
by Chris Warburton's generic sideways ROM header generator, I created
the first as a new list option for BASIC and bit 3 in LISTO allows
multi-line statements to be split up. Full documentation is included but
basically lines such as:
      100AND#127:STXj2%:TSX:CMP&105,X:PHP
      110LDXj2%:PLP:BNEstarcmp:LDXj1%

become:
      100AND#127:
         STXj2%:
         TSX:
         CMP&105,X:
         PHP
      110LDXj2%:
         etc...

This can be used in conjunction with other list options. See the BBC 
User Guide for LISTO options in bits 0..1..2.
   I haven't bothered to submit all the documentation for RAMFS again as
I assume most readers will have the EUG #50 disk articles to refer to.
However, the new version on the U directory on this disk has bug one
fixed and is up to 50% faster for sequential ops, allowing 21.7kb per
second.
   Onto other things. In EUG #51, John Crane commented on LS120 drives
which, for those who missed it, are drives that read/write their own
120Mb format and also Double Density and High Density floppies too.
   Indeed, Acorn disks do start at track 0 (both DFS and ADFS formats)
and PC disks have their boot sectors starting at track 1. I'm not sure
what's inside these drives but if there's an off the shelf floppy con-
troller chip, it would seem foolish for the manufacturer to not allow
access to track 0...but when has foolishness ever stopped anyone?
   The main stumbling block I see with LS120 drives is the EIDE inter-
face. I challenge anyone out there to build a working EIDE interface for
the BBC and write a filing system to steer it.
   I think we should stick to SCSI where all the work is done by the 
hardware and the host computer just coughs a few commands down the 1MHz
bus to do the work! Or pop it onto my RAM filing system (with up to 8Mb
storage) with battery backup. That should be enough.
   Iomega ZIP drives also look quite funky.
   Finally, I recommend, as John did last month, buying a RISC OS-based
machine to run alongside your BBC (switches channels on his TV card to 
the AV input to check the BBC's still working OK then switches back to
the 9 o'clock news).
