Re: USB Keyboard IF
Nice project - does it deal with CRTL, ALT and SHIFT keys and combinations of those with other keys - the IPC code has some special cases - particularly with the HERMES IPC replacement - that you may want to handle.

Re: I hate snipers
I hate the auto bid bots. My usual trick if I really want something is to look around to see if anyone is selling the same item - and if so whether there is a buy it now for a sensible price - quite often I'll watch the same thing on several ebay items - and if one goes silly on bidding - I will tak...

Re: 720K floppy and trump card
Or do you mean fool the trump card into thinking the drive is 780K (QL uses a slightly different format so more space is given)? Biggest issue with using the 1.44MB drives is they were mostly meant for the PC market - so come selected as "Drive 1" and use the cable twist between 1st and 2n...

Re: Do the shuffle...
I was probably going to go for assembler as I'm a glutton for punishment :-) for the 8 bit value - I reasoned that I would be able to loop around 8 times, using the new value of the bit assignment as a mask and decide whether to AND or OR the bit to set it's value based on the original value. I was ...

Do the shuffle...
I have a question relating to bit reordering in a byte / word or even long word. I have seen algorithms to swap one value for another by using XOR technique, and also algorithms to swap bits in the byte or word from lowest to highest and vice versa (reversing the bit pattern). What I want to achieve...

Re: NOOB QUESTION: learning machine code
you'll probably need more than one book - as there's 68000 assembly programming - and then there's the specific application of programmming 68008 code on the Sinclair QL. The book Dilwyn mentions is a good one, for more general techniques I found the cybex "Programming the 68000" a useful ...

Re: Minerva - In need of some help please
Dilwyn has a useful list of some of the ROMS associated with the QL and it's peripherals - there are some Sandy ones amongst the list:
