====== QL-Bus ====== QL Bus was a 5 slot expansion bus card from German company ABC Elektronic and designed by [[qlwiki:Jürgen Falkenberg]]. This allowed you to plug up to 5 QL-compliant cards such as memory cards and disk interfaces to a QL, although some of the older QL ROM versions were only able to detect one expansion card ROM at a time. We believe the picture below is of the QL Bus, although it is badged JFC ([[qlwiki:Jürgen Falkenberg]] Computer Technik). One of the slots are marked 'Hi' and another 'Low' and it comes with 5 resistors, presumably to help with compatability. More information is required. {{qlwiki:ql-bus.jpg?direct&240x180 |QL-Bus from JFC}}
