Re: Future PSU designs

...and it's a PSU with high voltage. Mess it up and you may not even be able to ask Chris for help! ;-)

What's all the extra holes for on the mains side?
You mean the tin plated bit at the front etc ?
Yeah. I think I was confused when looking it the pictures. Those are the 5V, 12V, and GND right?

Re: STFM case remake

Really cool. Too bad nobody seems to know whatever happened to the other (ST/MegaST/STe/MegaSTe/TT/Falcon) molds.

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: 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.
