My Q-disc PCB is labelled CST-QD3 with ROM 1.13 (c)1985, bought in '87.dilwyn wrote: Interesting: the QL Wiki only refers to three versions of the interface, with pictures of two versions - the later one shows an EPROM with a "v1.19 (1987)" label on the EPROM. https://qlwiki.qlforum.co.uk/doku.php?i ... _interface
The layout is - almost - as the Wiki image model '84.
The Utilities disc is V3.0 with Convert, Backup, Filed, Disced & RamDrive.
There is no mention of any version in the manual.
The question is, does a later v1.1x work in any PCB version?
