Disk interface

Trying to get my old QL set-up rebuilt.
The BBQL will be going off for total refurb soon, and I've got a 2x3.5" disk drive unit to plug into it.
It has 512L internal RAM so a simple Disk interface w/out extra memory is what I'm looking for.
I keep an eye on eBay but not much turns up that's suitable.

I'm open to whatever is available that works ;)
A manual would be useful.

I'll take some pics of what I have, and test them too :)

Ok, I have the following with photos attached. I'm not sure if the PCML one has ram chips under the cover but there are empty sockets. The other is a Cumana and a Kempston. All a bit rare and a leftfield selection :lol:

Sorry for the delay, in the end I had to order a new QL scart cable. Couldn't find my gbs8220 anywhere :( Well two cards work as shown, and the poor little kempston seemed dead.

Looks like it is something wrong with the scart cable - red is shown as yellow
Maybe there is a short between R and B
