Re: QubATA 3.10 I/O area address

I think in the Qubide assembly source, the I/O area is defined as a manifest constant - so changing it once and reassemble does the trick. QubATA driver and ROM image is in compiled form. But then this was just a question. If the image is loadable anywhere - why is there a reference in the REXT file...

Re: QubATA 3.10 I/O area address

The project in question is to integrate a qubide into a black box QL 'clone'. It's a one off experiment, but I plan to use some part of the largely undecoded QL expansion area between 18000- and 1c000, as 'technically' the I/O is internal, and let's face it - Sinclair are not going to be using any o...

QubATA 3.10 I/O area address

A question on the QubATA driver: Is it possible to have the ROM loaded at one address range, and the hardware address as described by the GAL's at another address? I see in the driver it looks like it's coded for 0C000, but I am guessing the driver code itself is relocatable. Does the address repres...

Re: Minerva v1.66 original rom and carrier

Hi Martyn,

I am in the UK too, I would put this in a Jiffy bag, so owing to thickness this would be large letter postage.

I would estimate about £1.22 for 2nd Class, and £1.30 for 1st class

Thanks,

Dave.

Flip over backplane - DIY

This is my flip over backplane that was used to house a gold card and sawn off QL into a slim case

It worked remarkably well, despite the basic nature and no ground plane.

Yours for £5 plus postage.

Incomplete Rebel backplane unit

This is half of the RB500e backplane kit - not sure what happened to the other half - I think it was consumed into another project and is long gone.

This piece is the 4 slot backplane - and might suit some one experimenting...

Bargain at £10 plus postage...

Mplane for QL - ideal for homing in a slim PC case

Unused Mplane - was going to be the base of a Z180 unit along with the trump card I was also selling - I went down the P112 route in the end.

£45 plus postage - I imagine these are quite rare now - so grab a bargain...
