I like technology - new, old and even older. Current project: running as many Infocom (z-machine) games as possible on CP/M z80

#EchoesOfTheFuture en castellano acaba de aterrizar en #MSX. Para mí, la pantalla de carga más bonita es la de este sistema. Si eres fan del estándar que quiso poner orden en el caos de los 8 bits, este viaje es para ti.

Enlace de descarga en el siguiente post.

@mxb03523 Your platform is excellent for creating games across many computers. Would it be possible to add another platform to the list? I'm looking at how to add Agon Light, and I don't know if that is something you can help with?

IMPORTANT ANNOUNCEMENT: I started talking with Mike Austin in 2022 about preserving the Level 9 archive: A-Code compiler, interpreter, games, specs. Today Mike contacted me and told me THE MAJORITY IS NOW ON GITHUB. Enjoy! https://t.co/YYFtBR2OGG

@Heber_Limited Thanks @Heber_Limited - ordered one and it arrived quickly. Great case and the controllers feel solid! I still need a new USB-B power cable but in the meantime, I rewrote my logo program to better reflect the #Console8 #retrocomputing #z80 #ez80

🚨 #EchoesOfTheFuture is now available on #ZXSpectrum (requires CP/M)!

Thanks to @sijnstra Vezza interpreter, the adventure continues on this legendary machine.

Another wet weekend, another #Vezza release! I was asked to adapt my #Infocom #zmachine adventure interpreter to the #SinclarQL which uses a #Motorola 68008 CPU but has an emulator for #z80 on CP/M 2.2 called SUCCESS. Download it now: https://t.co/1H8aEbx0pP #retrocomputing

[Shawn Sijnstra @sijnstra]

@DaReInt Fantastic! It's great to see my software get a good workout! And glad it performs to expectation - speed was absolutely my main design consideration. The games have to be enjoyable to play.

@erikarn The best part is that you'll need to check A and HL because the return registers changed between versions.

[Shawn Sijnstra @sijnstra]

@erikarn It's using the BDOS function that returns the version number - i.e. BDOS function 12.

[Shawn Sijnstra @sijnstra]

I've improved the #AgonLight implementation of Daniel Martin's #TRSOS to make a more authentic #trs80 experience. Improving the display capabilities on #Agon was the goal. After many hours work (and help on the way), the results are great. Before & after. #RetroComputing

So excited to see more physical releases using by infocom interpreter Vezza/M4ZVM!

Time for another bit of #retrogaming fun. I've always wanted to play Akalabeth - Lord British's start to the Ultima series. Well, using @nanochess port to GW #BASIC, I've been able to quickly convert to BBC BASIC for the #AgonLight. My beta version: https://t.co/7sLPW8VS4N
