Maybe some were made buffered to allow for longer connections, or to cater for more types of card. I do remember the late Dennis Briggs (Adman Services) telling me that it could be hit and miss whether unbuffered expanders worked with some combinations of cards.RalfR wrote: ↑Tue Feb 04, 2025 2:15 pm I always found it interesting that certain connections in the BUS have to be buffered.
When I built my QL in a small PC case, I built a standing bus extension behind the mainboard, and also a slot for the QEP-III on the left side of the case, which you could plug in optionally. An Expanderam and a SuperQBoard were in the bus behind the mainboard and everything worked perfectly, without any buffering.
Perhaps it also depends on the QL itself whether this can work.
CST Expander?
