Hi Derek,

I guess it's been quite a number of cups of coffee indeed with 1GB

No, just drink slowly.

The best way is to make a small partition on WIN1_ and then use Partition_exe to expand WIN1 and add other WIN drives.

If there is a next batch of Qubide, please count me in with one. I'm really interested. Regards, Martin.

And me too, please, please, please.

Hmm. I'm using my second qubide in an aurora setup with a super gold card, qplane with super hermes and I keep getting lock ups after a few minutes. Keyboard goes unresponsive. I get no lock ups if I remove the qubide. I have the jumpers set to the default with no jumpers fitted fc000.

Any ideas?

Two little question

- Has you test your second qubide alone ? (only QL+qubide)
-This one is interesting for me. How your system gives power to those interfaces? Use original +9v power supply? has qplane its own power supply? 9 or +5v?

I've not tried the other one yet The system uses a pc at psu which powers the qplane and the super gold.

Oh I also removed the ram chip and gal as in the online manual.

I think I know what it's the problem.

Before give you an explanation, please make this test .
Put the QL+qplane+qubde clone.
Take a tester and check that there aren't +5v in any chips of qubide (for example within pin 10 and 20 of the gals)

That's a bit advanced for me I noticed in the original qubide manual it mentions jumpers to be enabled when it's being used in a +5 volt environment.

That it. If you will see a photo of original qubide, there are two jumpers near 7805. It allows do a bypass between +9v and +5v.

When I studied the scheme I didn't understand this possibility (indeed, I thought it's a bit dangerous possibility) until a read the qubide manual:

Running the board from +5V

There are two connectors (J6 & J7) which when left open (default
setting) allows QUBIDE to convert the 9V unregulated supply given out
by the QL into +5V via the 7805 Voltage Regulator on board QUBIDE.
If you have a powered backplane, where the 9V rail is being supplied
with +5V, QUBIDE will cease to function. To get QUBIDE functioning
again you must place a jumper on both J6 & J7. This will by-pass the on
board 7805 Voltage Regulator and supply the interface directly with
+5V.


WARNING !!!!!!

If these jumpers are not removed when plugged into a standard QL
arrangement there will be FATAL consequences to QUBIDE and possibly any
Hard Drive connected to QUBIDE.

And this is your problem, your qubide doesn't have vcc and it doesn't work ( and your QL see an unplug device and has problems).

The bad new is I thought I'll never find a person like you ...and I quit those jumpers in my clone. The solution is easy : solder a wire between pin 1 (left pin) and pin 3 (right pin) in 7805. I expect you have a friend that can make this little modification (and remember that you can't use this qubide in a standard QL if you don't quit this wire).
