Memory Expansion Etc.

Hi All,
I was wondering what options I have for memory expansion on my QL please? (other than waiting and hoping something like a GC or SGC comes up for sale on eBay)
Some form of memory expansion is the main thing on my wanted list (preferably without needing to break out the soldering iron) but a floppy disk controller would also be good
Any thoughts/advise please?
Many thanks
Tony

User Chr$ tends to build
RAM expansion boards every now and then, if I remember right - better ask him directly. These would keep the CPU at the 68008, just expand the RAM to the original anticipated maximum.
If I were you, I would really re-think the floppy approach: Floppies are, in my opinion, the least comfortable and most expensive replacement for microdrives. Have a look at the
Qimsi thread here that gives you an SD card storage solution which is easy to install and operate (and allows uncomplicated data exchange with modern hardware). Until you have collected second-hand drives, an interface, and some sort of power supply, you will be well over the cost of a Qimsi.

As for technical infos on QIMSI, you can get an overview here:
viewtopic.php?p=52683#p52683
Likely you'd have to wait for the next production batch though.
The availability of QL RAM expansions is precarious. The best is to follow Tobias' advice. If that fails, I also don't know better than watching the "for sale" section and the usual second hand platforms.

Thanks for the info/advise Tobias. Have DM'd Chr$ re the QuintupLer as I'm not really bothered about keeping the 68008
I already have powered floppy drives I could use (I'm a bit old school) but will look into the Qimsi as a more flexible alternative thanks

Taking onboard the advise I've asked to be put on the lists/queues for a QuintupLer & QIMSI, thanks

Got your message, thanks Tony.
I have one available for you right now, but tend to always make sure I have a couple here and will always make on demand for anyone that wants one. Same for the VGA adapters and felt pads. I try to make sure I have the required parts available at all times

Have ordered a QuintupLer from Chr$, my new QL adventure begins!
Many thanks Chris

I have a 3.5" Floppy drive which I'm going to try and use (along with a GoTek) with the QL when my Trump card arrives
It's one that only needs 5v and I'll be powering them both from a 5v 2amp PSU for now (hopefully)
But I'm unclear as to whether I need to cable just the 5v & a ground, 5v and both grounds or provide 5v to both the 5v & 12v lines
Any ideas please?
Many thanks
Tony

You won't need the 5v on the 12v line. And one ground should be enough (use the one next to the 5v).
