Hrmm, I feel like this might eventually lead to pain...however, will probably be very useful once I get farther down the road writing this Z80 emulator.

This week on the blog: Given that for 10 years now I've used the 48k Spectrum as my default platform for testing my Z80 code before moving it somewhere less cozy (Mega Drive, CV, TRS-80...) it's kind of silly that I've never really systematically dug into the system line itself to make it dance and sing.
Today we fix start fixing that, with the now-traditional tour from the BASIC standpoint.

Retro Computing Nerds, especially Z80! I'm trying to use DeZog to reverse engineer a ROM routine. I need to implement bank switching via the ioMMU config. I have it half working, but it doesn't appear to switch properly unless I code case for all banks. Does anyone have any advice on this? I have been looking at DeZog's source code and half getting somewhere, but the documentation is vague.

I've rewritten my #Console8 logo player -also works on #AgonLight - and updated the video file for 2 reasons. 1. it was a bit long playing the whole thing, and 2. I wanted to play a higher resolution video, covering as much of the screen as possible. With a bit of video editing (cutting and cropping to make the most of the logo at the end), plus taking advantage of the VDP code for both decompression and bitmap expansion, this is what my boot sequence looks like. I've left the logo to linger a little, but that's optional and a quick change to the script.

This week on the blog: ...mostly showing my work for what fed into last week's post, actually. A line-by-line comparison of four implementations of the same function on four variously related retro architectures.
This is gonna be one of the crunchy ones that most folks will want to skip but that the folks who like it will *really* like, in my experience.

Yesterday I had the great pleasure to attend a documentary screening and panel session where Prof. #FredericoFaggin was the guest of honour. This was organised by the #Italian Luxembourg Chamber of Commmerce and introduced by the Italian Ambassador to #Luxembourg. #Faggin invented the #microprocessor and designed the #4004 #8008 #8080 #z80 and later on via #synaptics #touchscreens and #touchpads .He is a true #pioneer
