Do you have also added the clamp diode option to all the pins ? Yes, that is mandatory of course. I guess there 'll be no problem using resistors for the reliability in the long run because they are quite big and the longer rise time doesn't affect the speed, for the speed to the QL bus is not high...

I have a question: could some way be implemented to get the video output of the QL through the video port of the QIMSI Gold? I did in fact implement this for Gold Card and Super Gold Card as a fun project. Requiring one extra wire. Probably I could also do it for 68008 QLs with two extra wires. But...

Peter you make me crazy. :shock: I 'm still enjoying the QIMSI base board and you already are peparing an astonishing new super upgrade. Well done. Keep me in mind for a future list of buyers. Interested for sure. Hi Marco, many thanks! I'm glad you are not angry with me, bringing the next interfac...

Ok I understand better how everything works. Not the answer I would have hope but I will find another QL to use with my QIMSI Gold when it arrives eventually. I was hoping the support code to drive the keyboard and such was provided at address 0, so the 68008 would boot using the special code. Tech...

Hi, I rarely use QLiberated software, because it does not allow copyback cache on 68040 and 68060, totally crippling those CPUs. Or even worse, some even require serialized cache mode, which makes high end machines like the Q60 insanely slow. But some QLiberated pieces are really nice, so I'd like t...

Looks a bit like a 68000 (FPGA) based Raspberry Pi Zero accelerator from the ZX Spectrum next, degrading the QL electronics to a servant, sort of, right? Indeed the QL electronics would usually become servant to the accelerated CPU. For the most part, that was already true for the Miracle Gold Card...

I manged to get a flight sorted to Koln, no rooms available at the venue hotel, [...] That is very surprising. From what Detlef told me, they should have plenty of rooms free that weekend. If you can still cancel the other hotel, better contact Detlef and let him check back. Fantastic that you can ...

Wow! Well done, the Spec looks great, what could be a better for the QL’s 40th Anniversary. Many thanks! Question: Be interesting to plug into one of my QL’s. Will you be able to include a case and when wired up for Sound can the Output be driven by both S/SuperBASIC BEEP and QSound commands. There...

Can other QL expansions be used with the QIMSI Gold? If you use QIMSI Gold as standard QIMSI, yes of couse, if they do not access $C000...$CFFF. If you mean from the accelerated CPU? Not directly of course, because a) there can be no external bus master on the ROM port b) they are at locations wher...

Yes it will - but from the accellerated QIMSI Gold CPU, you will not be able to access the (S)GC floppy. For that purpose, you can still use QIMSI Gold as standard QIMSI.
