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

Re: Cumana Reborn DSK support
...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...

Re: Cumana Reborn DSK support
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 ...

Re: IJK-egoist new joystick interface by [raxiss]
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.

Re: Printer?
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...

Re: Printer?
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...

Re: substraction of two 8bits signed values into a signed 16 bits
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...

Re: substraction of two 8bits signed values into a signed 16 bits
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...

Re: TSN 1-2450A instead of LM7905
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 .

For this particular issue the ONLY relevant solution is: :D - crossing finger and praying Now seriously: There is one BIG difference which should be always taken into account and it is: what type is your project: [ C with some ASM functions eventually ] or [ ASSEMBLER ONLY ].
