Re: 68060 based QL system?

I favour a new design - with perhaps a blitter and or interleaved access to video frame buffer.

As resolutions get higher, and colour depth increases - the amount of data that has to be moved about is much larger - and this is what slows down the Q68 when chosing the higher video modes. In this ...

Re: New Q60 Boards

I am hoping this would only be a short pause - I've always found Derek to be a good fellow QL'er and have benefitted from some of his expertise and parts.

I hope you just take a short "QL Holiday" Derek, you have a lot to offer.

Re: TF Services I2C Interfaces

In terms of the I2C interfaces - would it make sense to make them QWIIC compatible (from a connector point of view), as there is a growing library of these boards becoming available for experiments.

Re: Win 11 networking


...

I would never trust all my stuff to any cloud only; I always keep one copy at home and another at a friend's who lives some miles away. Its worth (IMO) to have a few extra USB HDDs for that purpose. Yes, it can be hard to keep everything up to date, but at least all will not be lost while I ...

Re: Win 11 networking

Microsoft have been known to put out updates with issues ;-)

I think rolling back and then having it reapply a few days later will potentially load in a fixed version - but if your machine already thinks it has the update - it won't check for the same update again - so you'd miss a sureptitious fix ...

Re: Retrofest UK 2025. May 31st / June 1st

There was a project to provide a computer controlled Zero 1 interface - I think it was a US based project using 6502 - in Model Railway Electronics 1984 edition - can't find the magazine online, but I have a scanned copy in pdf format of the main circuit. You can PM me if interested.

I have been ...
