I don't think that this wire was the new problem.

You told before but I think you need check some voltage in some points of the system to know if we are doing the right things. If you don't have a tester I expect you a friend that can help you.

I probably do these tests:

- Quit the wire and test the qubide with a standard QL. We need know if the qubide works and if it works with your QL.

if it works well
- Put qubide+qplane+QL (the qubide without the wire) and check that voltage it has in pin 1 of 7805. Like it didn't work, we thought that we have +5v instead +9v but now we must be sure.
- If you see +5v then the wire is necessary. In pin3 you will see lower vcc.
- I think you told us but your qubide should not have the 512k expansion . I'm sure that other board has its own ram expansion and you can't have 2 expansion together.

if it works well
- Then we can think there is an incompatibility within the qubide and one extra board.

Well I've refitted the Qubide into my white QL with the wire removed and the memory chip plus gal fitted and everything seems ok. No freezes or lock ups :)

Ok with a meter it was around 5.4v on the input and just over 3v on the output. I'll redo the solder with some better wire I found!

Woohoo I think it's working. Not crashed once yet touch wood. Reading 5v on pin 1 and pin 3 now. I did get one read 0 error when the qubide was initialising. But it's ran fine other than that. Just got psion chess on running.

Spoke too soon, freezing again and now wont detect the qubide on restart :( I'll just have to stick with using the clone on the black box ql :)

Please let me know if I should do something else other than post a request here.
Thank you!

Hello

Habi has passed me a new version of "Image Editor" PC software . It has some little improves and now there is a English version.

The new software is available in :

http://hardware.speccy.org/temp/qubide-i.html

Documentation section

I will update the tutorials soon.

By the way. Some Spanish guys asked me about make more Qubide and may be there are some people interested here. I'll open a new post in For sale to know it and make me an idea.

Bye

Hi

Ranma_Simon make me some interesting questions and one of them was if there are QL emulators that support qubide raw image.

My answer was no, there aren't. Most ql emulator I know support qlx.win hard disc image that have different format ( I think).

I know that there is a emulator that support sinclair QL and the qubide interface. It is mess emulator. The problem was that 1.56 mess version support sinclair ql + 640k ram + rom cartridge but not qubide and 1.59 mess version support qubide but not work very well and only emulate 128K ram.

Any other emulator? is possible contact with q-emulator , uqlx, qlay, etc authors to see if they can support this interface?

Bye

Qemulator techincally does as there is a plugin to use QL-SD images. They are the same as Qubide images but big endian instead of little.

Its a simple few lines of code to convert back and forth!
