Well,ADFS can be fitted to any BBC machine,including BBC B,Electron,and of course the Master series.The BBC will however need to have had the normal 8271 disk controller swapped for a 1770 board.See my forsale list for details of how to get one.The ADFS ROM will sit happily in any of the board's ROM sockets,though lower socket numbers are better. RAM can be added to ATPL boards,they sit in the two sockets nearest to the keyboard connector.They too are available as spares from me for £4.40 each. As regards fitting your BBC with 3.5" drives then this is no problem.As far as the computer is concerned it doesn't know what shape the drive is which it is connected to.Hence no special formatter is needed.3.5" drive fitting info is given on the reference section of my webpages: www.york.ac.uk/~rps102/bbc/bbc.htm or can be obtained by sending two stamps and your name to my postal address.

Without seeing the unit,if the lines are vertical and happen no matter what the video source is then it sounds like one of the lines is stuck on the user port. This could be caused by several things: 1.User port has dry solder joint 2.User VIA (6522) has died 3.Broken lead in the cable 4.Dry solder joint in the digitiser 5.Fault with a logic chip in the digitiser (though it is unlikely that just one line would go) If,however,the lines are horizontal then I haven't got a clue.
