Hi Neal,
It's been quite a while since we communicated. Congratulations on the successful booting of NitrOS-9 L2 on the Multicomp09! It sounds like Ole has been a really big help to you. When will you be uploading the new additions to your web site? I will have to check your web site to see what is new.
Concerning my IT Training coming up in January 2018, I am in a holding pattern until then. I have one final interview in May when I meet one of the Business Advisory Council members. I will find out then that I have been Officially accepted into the Network and Server Support Training Program.
I have had a major upset with my Windows OS on my laptop over the last couple of months. It has taken me that long to finally get everything straightened out. I finally was able to reinstall the drivers for my USB to RS232 serial cables so I'm back up communicating with my SBC computers! Yea!
I want to check out what you have done with NitrOS-9 L2 as soon as possible. Please let me know when the files will be available. Thanks a bunch! Take care my friend.

Subject: [Coco] NitrOS9 LEVEL 2 running on multicomp
(this is not an April fools prank)
Back in October 2015 I announced that I had succeeded in booting NitrOS9
Level1 on my enhanced version of Grant Searle's "multicomp" FPGA-based computer.
Today, I am excited to say that I have succeeded in booting (in emulation)
NitrOS9 Level2 on that same platform.
The board is described here:
https://www.retrobrewcomputers.org/doku.php?id=boards:sbc:multicomp:cycloneii-c:start
It now runs CamelFORTH, BASIC, Buggy, FLEX, CUBIX, NitrOS9 L1, FUZIX and
NitrOS9 L2
As for L1, the L2 boot image is a standard floppy disk image file, slopped onto an SDcard at a Known offset and accessed by the disk device driver accordingly. This crude but effective technique allows the SDcard to hold multiple disk images - the images for multiple OS and bits of software listed above co-exist on a single SDcard and can be invoked by commands from the boot ROM (CamelFORTH).
Getting this working has also involved improvements to exec09 emulator, most particularly to add interrupt support and to improve emulation of the UART.
This port has been an on/off activity since mid November 2016. It has involved lots of poring over source code, single-stepping and analysing reference instruction stream dumps from coco3 emulation under MAME. My fellow developer Ole can take lots of credit for a lot of this debug work.
Even if you never use a multicomp, you will eventually benefit from this port in the form of various tidy-ups to the NITROS9 source code.
Boot transcript (from exec09 emulator) follows.
Neal.
