Re: Free ICs , CPLDs to good home !

I am quite sure I emailed you for some ICs and we even exchanged a few emails, but never got them... Probably I misunderstood something?

Re: A new well-known compiler

I did not want to start a debate, really. I find them fun and an opportunity to learn a lot (and I am always curious and willing to learn from others). I understand that you want a decent C compiler so you can test things, maybe mix with asm... It is perfectly OK and I understand that. lcc65 is crap...

Re: Novalight - very fast tape loading

Impressive work indeed! A great achievement.

I must find a way to make audio loads again on my Atmos, because I lost the laptop which was really reliable and couldn't find a way to make turbo loads work again :(

Re: Oric Speech Synthesizer + Cumulus/Microdisk

Oh, I see... I always thought that R/W was only set in the period Phi2 was high, while the ULA accessed the RAM when it was low (or was it the other way around?), but it seems that indeed the state of Phi2 must be taken into account too. Okay, I always loved hardware but always also sucked at it and...

Make sure, please, to use the latest sources here https://sourceforge.net/projects/euphorictools/files/Tape%20tools/Tap2CD/ This version includes 2 modes: one checks for errors every 256 bytes (CRC) so it is great for adjusting volume and settings (it ...

Re: Oric-1 RGB to SCART - pin 8?

Thanks for trying... it was worth it, though unsuccessful. Then I ran out of ideas, to be frank. My cable is a direct connection from the Oric's port to the SCART, with the addition of voltage to select the RGB mode and everything works nicely. Could it be that the SYNC signal is being filtered by t...

Re: A new well-known compiler

Let's face it, guys... a C compiler will never generate good code for a 6502 architecture. Simply C is not designed for so limited 8-bit processors. 1/ lack of 16 bit registers and operations (arithmetical operations suffer, pointer management...). Remember the base type in C is 16-bit (int) and eve...

Re: Oric-1 RGB to SCART - pin 8?

Still, pin 18 is not connected to ground. It would be a quick test, just to make sure it is not the cause.

Re: Oric-1 RGB to SCART - pin 8?

So you made a direct cable from RGB to Scart and connected it to the input Scart of a TV... There could indeed be some kind of incompatibility with signals (I don't know if you put some resistors or additional circuitry) but the main suspect (for me) is the SYNC signal. Either it is not well connect...

Re: IOUG

I think other archiving sites publish the mags with all that information without any problem. Doesn't help much, as they might be doing the wrong thing, but I'd say it is quite safe, being so old and (as you said) information that was already public.

Re: Oric Speech Synthesizer + Cumulus/Microdisk

I always found all this confusing and cumbersome too. For all the strange designs of the Oric (video mode, impossibility to disable ROM without external hardware, and so on), the VIA replicating its registers all throughout page 3, instead of using just 16 addresses (and keeping some more reserved t...
