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 optional case for it?

Thanking you,
Mark

Hi,

The Q68 is QL compatible computer board that implements 68000 based CPU running at 40Mhz.

See https://qlforum.co.uk/viewtopic.php?f=2&t=2181#p19837 for description of Q68.

The main operating system is SMSQ/E, but Minerva is available.

The Q68 will run most QL software.

Any software that uses the QL hardware may have problems, but I have found any yet.

I will add you yo the waiting list.

Here are some pictures:

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 are directly hardware compatible, including mode 8 flash and second screen.

Much better pictures of the Q68 can be found here: https://qlwiki.qlforum.co.uk/doku.php?id=qlwiki:q68

I do not think these are a disadvantages, the Microdrive and Floppy Disc access can be implemented by using MDI and FDI by Martin Head, which gives a access to Micrdrives and Floppy Disk images located in the QWA, FAT, partions.

There is a speed reduction in High Resolution and High Colour modes, but since the majority of QL software runs in 512x256 4 Colour Mode or 256x256 8 Colour mode, or Classic QL Mode, I do not think theis a problem.

All of the Digital Precision Software package runs on the Q68 and the majority can run in 1024x768 4 Colour mode. This screen mode looks very similiar to the QVME on the Atari TT030/Mega STE.

Looks a nice WIKI page, but the Q68 photographs.

Hi Keith,

I am in the process of trying to get PCBs manfuctuered, just a little cash flow problem at present.

I will keep you updated with the progress.
