Re: Acornsoft Elite

I believe very few buying customers preferred joysticks. Always the keyboard - actually tried some analogue joysticks on it recently and it was horrible! I found the keyboard controls pretty intuitive. Even though I generally prefer keys to joysticks, I always played Elite with a Voltmace analogue ...

Re: A300 and A400 style floppy drives

But of course it also needs to be over the /correct/ track and a 3.5" disk is 135tpi which works at about 5 tracks per millimetre. If you've tweaked the position more than very slightly then it's possible that the head might end up correctly centred over the wrong track. The easiest way to check th...

Re: A300 and A400 style floppy drives

CJE Micros have the original Archimedes drives: http://www.cjemicros.co.uk/micros/indiv ... -800KFD310

They are pretty hard to get hold of so I suspect that's why the price is so high.

Re: MOS Graphics use with modified screen width

On the B or B+, I think you'll need to setup a "multiply by 512" table and then set &E0/&E1 to point to it. I'm not sure this is possible on the Master as I think the equivalent table location may be hard-wired in ROM? Assuming you've moved the start of screen memory up by 4K, I also think you'll ne...

Re: ABC compiles Basic V to 6502? [ABC65]

Yeah I know. I take a similar approach in my 8 bit development using cc65 (C cross compiler for 6502) with inline asm for the critical bits. However C is a lot nicer than BASIC for writing anything halfway complicated (like a file server.) True - C is my preferred language but I guess it wasn't rea...

Great stuff - would be good to have a run through of this on one of the Dev nights if possible. It uses the smaller screen as an optimisation and so that X fits in 256 for MODE 4!

I wish I were better at this as it's amazing and definitely the best 8-bit version by a mile!

I'm pretty sure you could load Superior Speech to sideways RAM so it's entirely possible that someone burnt it to an EPROM and your memory is correct.
