Re: PSU alternative?

I found the following sentence in another forum: "The 15.6V AC can be replaced with anything 14 - 17V AC at about 2A. The 9V DC can be anything from about 7.5V to 12V DC, 1.5A on an unexpanded QL and 2A on an expanded QL." Is it true? Or will this overheat the 7805 regulator or other parts?

Yes, it is probable. Tipically, also the cartridge felt pad is damaged. Fortunately it can be replaced and sometimes the data can be recovered.

Re: Expanding the QL + other questions

Hi, According to the Minerva documentation, Minerva accelerates 98% speed of Lightning. But the text scrolling and displaying speed remain slow, apparently the same speed you get with previous ROMs. In any case, I also recommend Minerva for its completeness, reliability and high level of compatibil...

Re: Expanding the QL + other questions

Minerva ROM does not accelerate text mode; on the other hand, Speedscreen (and also Lightning I suppose) does accelerate the text display very much.

Re: Fire

So sorry for the fire, but happy you and your house are safe.
I well know the smoke smell: it's so terrible and difficult to neutralize. Many years ago a piece of wood of my kitchen burnt partially; it had been repaired, but still today it has some little smoke odour!

Re: Dual FDD problems

Which kind of dual HD drives set are you using? Is it a vintage device (designed for old machines like Spectrum, QL etc)? Or are you using a "new" one, containing "modern" floppy drives (the same used for PC)?
