I've tested the A590 with my Vampire500. Both the FastMem and the SCSI drive are working without any extra configuration. In fact, I used the WB3.1 install on that drive for my first steps on the Vampire. In the end, I didn't want more than the files on the drive and put it in storage afterwards. Th...

thanks bax, since i can't found doc about 68080, your posts are essential. i have no information about the execution times on 68080, so i asking: what is the best approach if i want to fill a screen with a given color? i loading the color values to registers, and ... 1 - use movem.l register-list, ...

So this depicts the Arduino EtherNet module, connected to the micro SDHC slot? Assuming that is the case, which low level protocol is being used to send TCP/IP and UDP packets through the micro SDHC slot / cable? Actually, the Arduino-centric version of these modules is not recommended. The Micro S...

Since the Gold2 release, the ACT LED will be lit when the "turtle mode" is on. The turtle mode for improved game compatibility is activated by a cache disable request.

Bax did some good progress on the SD-net driver, now this little beauty reach about 738 KB/s. Thank you Bax !

Download speed is even higher, 843 kB/s. Not bad for Half Duplex, I'd say.

Hey Bax very cool! Nice work. Love the humour. :) What sort of raw throughput is this capable of? I presume the SPI interface is the limiting factor? Does that scale with Vampire system clock speed? Cheers! Greg The SPI clock rate of the Vampire could be in theory on par with the other output pins ...

I noticed there is a network driver in the SAGA 0.11 archive (SDnet.device). I believe this driver is for an Arduino style piece of hardware. Does this add on exist for the Vampire 500 v2+ ? To me it would make sense if a driver was released then the hardware should be available for it. But then ag...

There are recurring questions about optimization for the Apollo Core. The most obvious of choices is AMMX, available with Gold2. http://forum.apollo-accelerators.com/viewtopic.php?f=10&t=25 But of course, Apollo Core has a number of additional tricks up it's sleeve. I'm going to outline a some of th...

Depending on available time, I've got the intent on outlining in this thread what the SIMD extensions to the Apollo Core offer and how the functionality might apply to the one or other coding problem. Please be aware that the extensions are a work in progress and might change without notice before a...

I'd suggest to have a look at VASM. I personally use ASM-Pro on a regular basis for quick'n'dirty tests but that one is limited to standard 68k instructions. Apollo-specific code can be generated with the next VASM. Phx made the necessary additons to VASM in order to support new Apollo instructions ...
