Re: re microdisc floppy controller board

I have 2 3.5 floppy drives taken from a PC and I am using a flat cable. The only thing you need is setting one floppy as DS0, which will be drive A or 1 (by default PC's were configured as DS1 as they did not follow the Shuggart norm and they did not use the lines to select ds0-3). You can alter the...

Re: Substraction and Addition

Subtraction in the 6502 always takes the carry into account, and it works the opposite as with addition. If the carry is clear, the sbc operation additionally subtracts 1. You need, then, to set it before the subtraction of the low byte and it will be cleared if the result decrement end past zero, s...

Re: Networking Orics.

Yep.. quite similar to the info I posted about people using the ESP chip for adding Wi-Fi internet connection to some old computers. The chip includes a full TCP/IP stack implementation and is accessed through SPI. This needs a serial port in the computer, which is something the Oric lacks. But usin...

Re: CC65 to DSK

Not sure if anything went wrong, but for AIC graphics I could only get decent results drawing things by hand. It is not really a graphic mode, so you need some experimentation to get nice results. I think it would be easier to develop the game (one phase, for instance) in black and white and then, o...

Re: Jasmin time

@Chema : I didn't looked at your last modifications in FloppyBuilder, but from your explanation I suspect where can be the problem. Can you try the attached image with the real Jasmin? It should work with Microdisk too and contains some read tests and a write test after them. Else unfortunately, I ...

Jasmin time

Hi everyone! A friend of mine got his hands on a Jasmin disk interface and has been playing with it. First the bad news. Blake's 7 is not working. It does on the emulator (both Euphoric and Oricutron, that is), but does not pass beyond the 'BOOTING TDOS' (was that it?) message. I have to ask for som...

Re: CC65 to DSK

Oops... Sedoric is in the OSDK C library. You should look there for an implementation to use with another compiler.

Re: CC65 to DSK

I know. You can try the Sedoric() function, which is a hack, and tries ro execute a sedoric command such as "!LOAD ..." (I have no experience with this, but it was quite straightforward), or take a long path using custom routines to load sectors and create the disk so you know which sectors your dat...

Re: CC65 to DSK

FloppyBuilder is intended for demos and specific games, such as my Blake's 7. It does not have a filesystem. I'd recommend using tap2dsk, as it builds a sedoric disk that can be opened, dir'd and copied with no problems. If you plan to access data I can provide some working routines and ideas, which...

Re: A new well-known compiler

That would be great indeed! However, if I remember correctly, the compiler generates fat code mainly because the backend is designed for 16-bit systems (I mean, it is using the standard 16-bit integer size), so it does not optimize things such as small numbers (8-bit), counters and loops. Besides, a...

Well done! Waiting for the Oric version with anticipation.
