Re: Desoldering Falcon NVRAM

Kind of tricky to do these mods without removing the chip from the motherboard first. Once removed you can just as well replace it with a new one in a socket. But sure, eventually the chip will no longer be available and then this mod will prove useful.

Re: BLITTER RE-CREATION THOUGHTS

What about a LINEMODE (for drawing lines) like the Amiga blitter?

Re: Yes, another frenchy

Welcome! That broken Falcon030 board is most likely fixable. Every Falcon rescued is worth a lot!

Re: Programming the Falcon030 - dusting off an old document

Very nice summary. Interesting idea with the interrupt code, although one has to be careful there - for instance if your code doesn't do anything else than having a tight loop receiving data from the DSP (and writing it directly to ST RAM), it may make sense to have interrupts in cached area as wel...

Programming the Falcon030 - dusting off an old document

Many years ago I started writing on a document on how to write efficient code for the Falcon030. 20+ years later I found the document on my hard disk. I dusted it off and decided to publish at least parts of it. Perhaps it will be useful to somebody. The first part is about the 68030 caches and is n...

Re: 32Mhz oscillator "issue"

Hmm, what's the accuracy of the original oscillators in the ST? Oscillators usually also deviate from the nominal value with time and temperature, but all the fullscreen demos I've tested on my now 30+ years old ST machines still work fine. How much can the oscillators deviate from the nominal value...

Re: Project: HDMI/DVI out for STFM

Awesome achievement! I'd be interested in buying one if the sync issues with opening the borders can be solved (I mostly use my ST to watch demos, so would hate to not have the possibility to watch old classics without switching back to the old Shifter). Do you have any plans on doing something simi...

Re: Falcon is freezing in demos

- Does any chip run unusually hot? - You can download our Maggie 24 intro for the Falcon030 (http://nb.atari.org/main.php?page=productions). It uses the DSP in the very first part, so if it's the DSP you will end up with a black screen and nothing more. - Check the pins of the chips on the motherboa...

Re: Do you use your retro system(s) for something productive?

I use my Falcon030 for programming demos (Devpac) and to create graphics (APEX Media).
Besides that I watch demos, and also play games occasionally.
