Some additions to VBS 3.0 Manual, Sep 7, 1994

  Thank you for supporting our Amiga product development by buying a legal

- VBS version 3.0 works on AGA systems (Amiga 1200 and Amiga 4000), all
  ECS and original chipset Amigas (Amiga 500, 600, 1000, 2000, 2500 & 3000),
  with at least 1MB RAM and with or without accelerator board. The 
  software works on any AmigaOS version 2.x/3.x (or higher). If you have
  OS version 1.3 or lower, you can use VBS1.5, also on the disk.

- If you have trouble running VBS on a PCMCIA memory expansion (A600/A1200),
  please remove the memory or run NoFastMem before starting VBS.

- On an IDE Amiga (A1200/A4000) make sure that the hard disk's MaxTransfer
  is set right!!  If you have problems restoring, you might have to set it
  to 0x1ffff (128 kilobytes)!
  
- On an AGA machine, try turning off Mode Promotion/VGA Only when
  experiencing problems. When using a high resolution pointer AND
  mode promotion, ghost sprites can appear while backing up, which reduce
  backup quality. Make sure to either use a lo-res pointer in this
  situation or to turn off Mode Promotion.

- On a very small minority of Amiga 2000s, one of the legs of the capacitor
  inside the computer at the serial port (from the receive pin 3 to Ground)
  might need to be cut if VBS won't work reliably! If you have problems on
  an Amiga 2000 (the Video Connection Check fails all the time despite
  correct connections) first test the VBS on an A500 to make sure it isn't
  faulty before doing this modification! This mod is easy to reverse and
  will not affect the operation of computer or serial port at all: the
  capacitor really is superfluous.

  The intended capacitor is one of a row of about 10 capacitors, about
  2" away from the serial port (near the internal serial port).
  On the A2000s I have seen the cap was marked 'C313', however as this may
  vary with motherboard revisions, please double-check using a meter to
  ensure the capacitor is connected to pin 3 of the serial port.
  
  This mod will probably also restore picture quality on the red control
  monitor output.

- Lyppens Software Productions now offers an add-on for A3000 owners that
  gives a black-and-white composite video signal, as required for VBS. It
  plugs in the extended video slot, and it adds a composite video RCA jack
  to your A3000.

- A version of VBS for IBM compatible PC's is now available! Contact LSP
  or your local supplier for more details.

- Even though VBS 3.0 is so reliable it even works on a cheap tape
  I would like to stress the importance of using High Grade tapes
  again, as they are measurably more reliable than standard tapes. I 
  especially recommend the SONY Ultra High Grade tape. They are extremely
  reliable and not very expensive.
