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!

Have you tried using any of the Falcon030 NVRAM tools around? Changing various settings, rebooting, validating...

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: Future PSU designs

No progress yet with the new ones.. busy with STE boosters and have 3 Falcons to repair which been stacking up for a while to do next :roll: Would you mind documenting the process of repairing the Falcons, by creating 3 blog posts or similar? Would be interested to know their initial state (what is...

Re: 3-in-1 monitor adapter soon available in exxos store

It would be great to use MyAES, but I have not been able to find any documentation on how to install MyAES into an existing MINT install. Do you know where I can find it? The links on the MyAES site for documentation are deadends. Thansk! I'm afraid that I've never used MiNT so I can't help you wit...
