Random updates

V6Z80P and EZ80P development continues… Work over the past few months  has mainly been  software related: FLOS, the V6Z80P’s default OS has been improved quite a lot with 2x-3x faster file loading,  script handling,  programmable function keys added as well as many small additions and improvements (with similar changes being made to PROSE too.)  I’ve also made a native Z80 commandline assembler and  an improved text editor allowing programs to produced in situ on the V6Z80P without a PC ‘umbilical’ if desired.

EDIT: 9th Feb: Parts are now on order for another batch of V6z80Ps – see this page for details.

EZ80P bits..

I’ve been improving the EZ80P’s default config (AMOEBA) a bit lately.. I’ve given the original token sprite system a bit of a once-over and it’s now able to support 128 sprites on screen without software multiplexing (40 sprites on any one line). Also added the option to line and pixel double the sprites and added a sprite-to-background priority system.

Have also improved the sound system - each of the 8 channels now has a loop flag which can cause an interrupt if desired, allowing samples larger than available memory to be played.

Cycle Perfect Spectrum 48 Emulator complete

Alessandro Dorigatti has completed his cycle-perfect Spectrum 48 emulator config for the V6Z80P! I’ve made a little kickstarter program which pre-loads the necessary files (Spectrum ROM and optionally, a .tap image or ramdump file) so the whole thing is now very easy to use. Here’s a video of it all in action – the programs shown were mainly chosen to demonstrate various technicalities..
