Absolutely correct, @Symoon!
Here are @Jeff's last changes which make Oric DSK writer working.

iss

HxC Floppy Emulator : Floppy image file converter v2.0.3.1
libhxcfe version : 2.13.2.2

Compiled from sources and 'oricdsk_writer' seems to work now! Thanks for the quick fix!

@Jeff: Does this means that HxC firmware for Gotek need to be fixed too?

iss

Welcome Magoric!
Your "CanariasGoRetro" looks like great place with lot of fun

Welcome!
Can you tell us more about your dflat language? So far we know that it works on 554.37 Hz

Does this mean that Cumana Reborn has the Microdisc eprom instead of the Cumana's? Because IIRC they were hardware compatible... (they must be, or most games would not work!).

Yes, exactly the EPROM is the same as in Microdisc.

iss

...does it need something specific in the controller EPROM? Indeed! Both Microdisc and Cumana need different EPROM to boot Cumana DOS. Probably it's possible with some patching on disk to make it boot, but I didn't check this in details. The problem is in the different names of the system files, ii...

Thanks Chema for the info, so really, if we were to convert to HFE, we would have to: first decode the HFE file to translate it as a stream of raw data bytes then just use the 'old2mfm' utility to convert it to the new DSK format ? @retroric: Well, your guess is so close to the reality that I felt ...

Cool video, @rax!

@all: have you noticed the 2 spoilers in the clip:
* Putup for Oric by [raxiss] - brand new remake of the classic arcade game with puzzle elements with 50 levels.
* TapOric cable - to connect Tape port to smartphone or to PC sound-card.

Wow, nice catch. Interesting is that in my local file it's:

Code: Select all

digitalWrite(a_bus[i], a & 1);

Maybe I've uploaded something preliminary...
First post is now updated with the correct sketch!

Cool! Now let's save 3 bytes space too

:

Code: Select all

	sec
	lda _RayBeta
	sbc _RayAlpha
	bvc axmb_noOverflow
		ror
		tay
		lda _tab_divisor,y
		jmp axmb_done 
		
axmb_noOverflow
		tay
		lda _tab_divisor_acc,y
		
axmb_done
		sta _RayDivisor

For me, quick solutions can be made relatively easy with Arduino+PC+printer or RPi+printer . How does that work for Orics? It's really simple. Here is how I connect Arduino Uno to Oric's parallel port: Oric Arduino pin STB 2 D0 3 D1 4 D2 5 D3 6 D4 7 D5 8 D6 9 D7 10 ACK 11 Any other micro controller...

iss

IMO any printer (old or new) which has Centronics interface should work with Oric - you need only proper cable with the specific connectors. BUT , if we assume that 'all modern printers' have ONLY USB then you need such device - LPT2USB and short cable to convert the DB25 to IDC20 connectors. The pr...

Hey Iss !! So glad to see you back here :-) Yep, I'm back from a long vacation without Orics, Internet etc., ... just 'underwater void' ! :D uwv.jpg Anyway..., attached you will find your sources as one main C file and one ASM file. The idea is to redirect 'printf' to the printer output and to dump...

iss

Why not to simply use 'signed int' for RayAlpha and RayBeta too, keeping the allowed values in the same range -127..128 ? :? IMHO, this will not slowdown significantly the calculation. Then the translation to ASM will be easier and you can continue to use only 8 bits to index both tab_divisor arrays...

iss

Correct!

Just to clarify mikeb's magic numbers: the time depends on the RC group charging/discharging constant i.e.
T=R*C, or in the 'standard' case T = 2200[ohms] * 0.000001[farads] = 0.0022[seconds] or 2.2ms
