The Sinclair QL Forum

Hi,

A silly question, why not write the basic programs in the QL emulator as Toolkit 2 ED is a really good screen editor?

Hi,

I have been wrestling with awlful OSX operating, not impressed by Apple's interptretation of UNIX.

So the Mac Mini made see MorphOS loaded on, or sold eBay

Hi Martyn, The Altera EP1810LC-25T fitted to the QXL cards is rated to run at a maxiumum speed of 50Mhz. I think overclocking the QXL by putting an Oscillator of a greater clock speed of 50Mhz will cause the EP1810 to shut down or become too hot to run. I thought about fitting a 68RC060RC50 CPU with...

Hi, There was a M212 Transputer Hard Disc intrface for the QL featured in Quanta Volume 6 Issue 1, 2 The circuit diagram was printed in the Volume 6 Issue 2 magazine. I wrote to the designer, asking to support his development or possibily sell me one. But he never wrote back, I bought a Miracle hard...

Hi,

Just downloaded the Git Hub zio file, quite big program.

Writing in assembler was just wild idea... maybe C is better.

Can this be compiled with C68 instead of GCC?

Hi,

Can this program not be written in assembler saving a lot of space and increasd in speed.

I want to do more programming, so will have a look at this...

Hi Peter,

Sounds like this has already been done in the Gold Card, so I will stick to that.

Hi,

If there was an interface to fit a 68000 CPU in to 68008 socket, what problems would occur?

This is what the Gold Caerd does, with its own CPU and RAM.

HI Martyn, The QXL II+ cards, I have are using a 68RC040RC40M CPU from a Q40. Which has MMU and FPU, runs at 40Mhz. The QXL II+ clock oscillator, is 50Mhz, which runs the QLX board at 50Mhz, but the design of the 68040 reduces the clock speed by 50% to 25Mhz. The programmed Altera PLD Glue Chip is r...

HI Martyn, Thank you for the the timming software I will give it a go on my QXLII which I running at 20Mhz. The Altera chips, I fitted on the latest QXL boards are capable of running at 50Mhz clock speed, which in the 68040 is 25Mhz or half the QXL board clock speed. Interestingly enough, if a 68060...
