Re: Q68 Order Process

Hi, The only incompatibilities that eventually kept a few old games from working on the Q68 are the lack of the coprocessor and microdrives. Both were in my opinion design mistakes in the original QL, and I was not motivated to implement them just for compatibility. But screen and most QL registers ...

Re: Problem booting Super Gold Card

I don't have a SuperHermes (*), so I don't know whether the paper manual had full schematic, the PDF on Dilwyn's site only shows PCB layout. IIRC I had a PDF of the full schematic. Here is the link to the Suprrhermes manual: http://www.dilwyn.me.uk/docs/manuals/shmanual.zip There 2 manuals, the sch...

Re: Q68 Order Process

Hi guys, I hope you don't mind some newbie questions: What is the Q68 - is it a modern QL compatible board? Can it function as an original QL, i.e. can I run Minerva and my original QL software? Is it still possible for me to order one? Would it be possible to post some pictures of it and of the op...

Re: Backplane and other problems

Another issue with the Backplane maybe line noise in the connections.

The Qplane was issues with this and Mplane was produced to try and remove any noise generated from the interconnection of the backplane to the QL.

Maybe an area worth looking at.

Can you tell me where I can get the Gold Card schematics?

Re: QLUB Adapter - Initial Release...

Just ordered a Teensy++ 2.0, they look as if the are getting rare now, the one I got was last from vendor, PJRC.com is now out of stock for good? (https://www.pjrc.com/store/teensypp.html), Nice to see the AT90USB1286 is still plentiful though, I don't suppose it would be difficult to make a QL spe...
