A backplane - like the one tetroid sells will get around your used expansion port. In theory you could put your eproms at either location. To be linked into the system, they would need ROM header and some code to activate the contents. Ideal for things like toolkits. Not sure if there is a 'ROM' Dri...

The ROM space would need to be accessed by the expansion connector - and the memory map is a bit misleading too Minerva ROM will scan the various places that ROM can exist - so that will find any ROM's you have there, older ROM versions tend to only scan for the first peripheral rom at 0c0000, and n...

C compilers - certainly in the microcontroller world - can produce assembler as output, so that any critical timing loops can be tweaked. Optimising compilers usually produce quite efficient code, so there is no outright reason why c could not be used. The hard task would be rewriting all the routin...

I've looked through several conectors and can't find a match It seems also impossible to find any connector with the correct distance between holes :( The famous CPU fan connector is very similar, but its holes don't match perfectly the QL pins. True - but it's close enough that a printed shell tha...

That looks brilliant!

When will this board be available?

I will be spending a bit more time on a couple of hardware projects with all this isolation going on. A keyboard adaptor for PS/2 to work with existing IPC - using a single pic micro and a handful of resistors, and build someone elses ps/2 mouse to quadrature signals board - again using a single PIC...

Try a post in the wanted section - someone on here often has spare parts or could point you in the right direction hopefully

Other countries can manage, why the hell can't the British STFU and listen to advice? Well, since you've come up with the topic, I find it a bit irresponsible that the UK is not taking action, nor is France doing it. Leaving the population at the expense of possible immunization is going to be defi...
