Very cool! Looking forward to trying this out. I hope there is a way we can load those files over DriveWire... On Bill Pierce's Orchestra-90cc web page I found this Orchestra file player that works on CoCo and on my Dragon 32 as well it turned out. It must be using the "compatibility" vectors for ke...

From what I can see Piotr = zaxon and this is the newly made controller mentioned in viewtopic.php?f=6&t=5362

You already found it out yourself, but in one of his videos https://plus.google.com/s/zaxoniec he shows switching between the 4 DOSes.

It actually looks like William recently added this to the development version: http://lwtools.projects.l-w.ca/hg/index.cgi/rev/e3f4aaa2a4e8 m80ext This pragma (along with pragma qrts) enables some uncommon behaviors to accomodate The Micro Works MACRO-80c assembler from 1982. This assembler was used...

Welcome to the forum, Kan! Cool stuff. Thanks also to Rolf for sharing this in the first place! I have a couple of suggestions: 1. bin2cas.pl can read the load and exec address directly from the DECB binary, so you don't have to enter them on the command line. But for lwasm to embed the exec address...

I'll believe you the day they find water on Mars...

There are some cheap switched PSUs on aliexpress (search for t-30a), but I don't know how well they would work. Search t-50a for more watts.

fridgemagnet, pics or it didn't happen

paul, maybe Jon had modded a Dragon 64 which takes -12V and not -5V on the motherboard.

Bosco, unless Fil2VDK translates DECB binaries into Dragon DOS binaries, this won't work because the RUN command is a Dragon DOS command that will load and run only a file in Dragon DOS format. Anyway, you are well aware that XRoar can load a DECB binary straight into memory without using DOS and di...

Thanks guys! Rob, I knew you would like the colours, your avatar gives you away :p

I am aware the site doesn't look good on iPhones, but for now I just blame Apple :-/

If you need someone to make tests on this, you can count on me.

Does the Orchestra-90 ROM include its own mini-DOS and access the disk controller directly, or how does it work?
