Well that was "fun".. maybe that'll teach me to tripple check before starting to put down tracesBlitter socket now on the top layer where it belongs, and the Phoenix blitter should fit.

Has anyone had any success with the STM1 optical mouse upgrade from amigastore.eu? I received mine today (version v2r0) and it's a bit pants really :/ Horizontal movement is super nice and the vertical one is too but only when it works as it should. If I move the mouse in one direction, stop for a b...
Oh cool. Would assume ST RAM wouikdnt be fast enough for it, or have enough RAM for it ? But paired with a 030 with 64MB RAM.. That would be pretty interesting ;) I don't think memory bandwidth is an issue but the size certainly would be. An 128kbit/s MP3 is just 16KB/s (or roughly 328 bytes per fr...
I did look into mp3 decoder chips a while ago. But couldn't find anything which would use external ram, they were all from SD card :( VLSI has a range of chips that can be feed with a bitstream from anything :) And they have a data-request pin that signals when the internal FIFO has at least 32byte...

Is it me being a noob, or the smd fpga has been replaced by a ball grid array ? That is correct the FPGA is now BGA based (UBGA to be precise) so it can fit within the Blitter socket space. One the chips are cheaper and two it enables us to get the board down to a reasonable size. As someone who kn...
So much free space, the possibilities are endless! :lol: Screenshot 2020-10-26 at 22.36.32.png Was originally planning on having an ethernet controller there, and the circuitry does fit in the space, but I'm more and more leaning toward having that completely separate and connected to the ACSI bus i...
