Amazing news! And several unexpected bonuses...

No “bytes free” delay on floppy disks and small/medium volumes

Really looking forward to the release. Thank you!

P.S. I didn't realise that you had access to the original EXDOS 1.3 sources...

It was necessary because when I first did a :dir on a very large but empty disk it took several minutes!

They came from Werner Lindner of Enterprise Gmbh several years ago. Zozosoft managed to arrange the source files and re-assemble them into a byte-for-byte match to the binary 1.3, and lgb hacked his emulator so we could run the Z80 assembler and linker on a modern PC

You both have done a giant's job. Maybe you are ...

Sometimes ... I hate my eyes. I downloaded and read the specification out of curiosity. It was an interesting read. Unfortunately, I found a number of typos, inconsistent memory size annotation and inconsistent indentation and font size of asterisk marked notes.

Have I already said that sometimes I hate my eyes?

I remember to read on the Werner Lidner thread that version 2.0 didn't add fixes, out of the 6MHz trick,

Did I understand that right? Are you compiling the sources on a modified Enterprise emulator? Does that mean the original was actually compiled on an Enterprise?

Your eyes haven't read the "preliminary" word....

No, but on a Z80 card also running at 4MHz in an original IBM PC, and all from floppy disks. There is a warning in one of the source files that it takes 20 minutes to assemble, but on a modern PC it takes about 2 seconds!

The way things used to be!!!

Was that how EXOS and IS-BASIC were written as well?

Yes, at the end anyway. They might have started on an Apple II with Z80 card which I also remember using (all these Z80 cards were to run CP/M!)

Thank you, hopefully the next version will be less painful!
