Re: Breaking news: The QIMSI Interface

Assembler most likely. Would use it as computing accelerator for chess algorithm. Oh that sounds cool - and still realistic under the given memory contraints. I really should document the bidirectional fast data link between the QL and the MiniQ68 coprocessor. By the way, it makes sense to have a S...

Yeah, or stuff like Mandelbrot calculation. I could imagine stuff like that 30..50 times faster than a QL.

Re: Breaking news: The QIMSI Interface

First this that comes to mind is SSL handling and creation of an SSH client, SFTP client and such. I’d like to tinker with this if I can get the gcc chain. Prefereably a Docker container :) My binaries are relatively old Windows version of m68k-coff-gcc that I compiled long ago. Of course one could...

Re: Breaking news: The QIMSI Interface

I have 3 QLs and all of them are maxed out with either super gold card with mechanical hard drives, QL-SD on another and a V-Drive on the last one… When I read this, I wonder if there should be a QIMSI variant which can co-exist with QL-SD. It could indeed make some sense to keep an existing QL-SD ...

Re: Breaking news: The QIMSI Interface

What a journey Peter, from the beginning with the first attempts to attach your Qzero to the QL Rom Port about one year ago and the uncountable ups and downs we have been faced? Oh yeah, but just for historical completeness: This didn't start with the Qzero ROM port adaptor, but an actual QIMSI pro...

Why not simply use an USB OTG cable with passive PS/2 adaptor as depicted in the manual?

Re: Breaking news: The QIMSI Interface

I have two QLs. One has a QIMI inside. Obviously, I would not deliberately try a QIMSI on that QL. But if I accidentally plugged a QIMSI into that QL (which already has QIMI) by mistake, would it cause damage? No damage at all. And if you don't load the QIMSI mouse driver, your QIMI will continue t...

Re: Breaking news: The QIMSI Interface

Great idea Peter, very useful! Thanks Leon! As you work on ZX8301 replacements, you remind me of a fun episode, abusing QIMSI as video interface, too. ;) I found that with a GoldCard or SuperGoldCard, it is possible to identify access to the QL video memory area with just one additional signal, whi...

Re: Breaking news: The QIMSI Interface

My understanding is that Peter has managed to build a "68k/SMSQ/E-based Arduino", and QIMSI is just one example application for it. Hehe yes, sort of... I just lack the time to write good docs and implement more I/O options. And Stephan probably does not want to build tens of thousands of...

Re: Breaking news: The QIMSI Interface

There are a number of very interesting and useful uses to put to a co-processor and, with the QIMSI's direct FIFO link back to the QL itself, we now have a viable solution (the FIFO link was always a bottleneck in my own designs for adding a co-processor to the QL...) Many thanks Martyn. If you lik...
