A la Decouverte du Telestrat p.203 (available for CEO members ): prise_minitel.png plus Telestrat schematics by Fred : modem_conn.png will give you idea how to connect the interface - follow ACIA 6551 pins to the DIN-8 connector pins. BTW, why not use first real Telestrat to check if the modem work...

Ok, I'm getting tired of writing my own assembler programs by hand in a TXT file, like this for instance: Address / cycles / op codes / Asm instructions / Comments 0431 6 20 6A E7 JSR #E76A Init du VIA ***ROM1.0: E6CA I'm resurrecting this old thread because of a message in Apple][ FB-group which a...

Here you are: Oricomms Ta-da-aaa!

I will second @ mikeb , from practical side any small 10uF electrolytic capacitor will do the job. About the voltage even 25V is OK. This are good quality ECA1EAK100X , but if you decide to use the expensive TSN 1-2450A then to complete your "boutique" Oric I'll recommend to use a polymer ...

Using @Dbug's library: :) Oric Owner 09 p.7 - just a review; Oric Owner 10 p.54 - more info; And Personal Computing Today (1985-03) p.51 It's stated that the software is on disk, so the interface should be compatible with Microdisc (at-least). And I think I read somewhere that the used I/O is #31c w...

Welcome! Happy hours with your Oric Atmos and lot of fun.

Just for now I will focus on the 16KB restriction to get a stable and '1.0' kind of situation :-) My 2 cents: Do not consider that all Orics have 16KB available for external ROM. Those with two 2x64 ROM chips probably are not "fixed", so only 8K usable. But maybe I'm too pedantic... And h...

Can you attach some pictures pointing which pinout you need?

Is by the way not only sprintf, have exactly the same in cprintf (but assume both are using the same printf as basis), Exactly! The format string is held in one buffer, other following parameters are processed in second buffer which is 'printf'-ted out assuming that buffer contains a C string - and...

Yes, I think too this is a BUG in CC65's sprintf implementation. Code: static char* colors[] = { "BLACK ", "RED ", "GREEN ", "YELLOW ", "BLUE ", "MAGENTA", "CYAN ", "WHITE " }; void main(void) { char i; text(); cls(); #i...

Oh my! I did not know you were in conversations for a oric version of vbcc! That sounds terrific. I skimmed through the posts and it looks incredible! This is very interesting and I think it deserves further discussions in the dedicated thread . I've uploaded updated (and optimized) version: https:...

Well, after I saw the info about 'a new compiler' - VBCC I decided to resurrect this thread again :). Using the aes256 example from my earlier posts I made test with vbcc too. I think the results are interesting and promising. All sources and a Makefile are in a new repo: https://github.com/iss000/o...

Cool! It reminds me of Turtle Graphics

Indeed, it's the mym payer and no magic - music loops from its start (at about every 2800 points in the counter).
Edit: Attached is the 'original' YM file.

Thanks a million ISS, you know why ! Your are making is all very curious now ;-) Trust you or Iss will let us know of something has been solved benefiting us all. No secrets at all :). On the download page: https://iss.sandacite.com/ijk/ you can find a link " IJK gamepack vol.2 by [raxiss] - w...
