Disk Images
From a Facebook purchase, I was able to obtain original MS-DOS 2.11 and Concurrent CP/M-86 distribution disks. The MS-DOS disks were intact and readable but they will not mount on any normal system because the format of track 0 is unique to Lomas. Patching it to make it readable in a normal machine makes it unusable on the T186 (you need to overwrite sector 0 with a standard MS-DOS boot sector).
Regarding the Concurrent CP/M-86 disks, disk 1 is not readable due to a destroyed directory. Disks 2 and 3 are fine. Pete Higgins did extract the files from each disk and those are posted. Online AI tools did grind away at the image and repaired it enough, but some of the programs need to be replaced, and it's still not bootable. Progress...
The PCDOS-winslow disk is a PC/DOS bootable image that contains Windows 1.0 configured for no mouse and a CGA monitor. It will work with the ColorMagic, but the user experience is bad without a mouse.

Questions
How big is the S100 ColorMagic-1.1-006 PCB?
It measures 254 × 137.7 mm and has 4 copper layers, 4.69 mm thick.
What parts does the S100 ColorMagic-1.1-006 use?
150 parts, built around the PAL16L8-5JC, 74LS384N, 74LS373SC and 74LS367PC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the S100 ColorMagic-1.1-006 KiCad files?
From the RichCini/LomasBoards repository on GitHub, at the commit this page was made from: the board is Color Magic/V006/s100_ColorMagic-1.1-006.kicad_pcb and its schematic Color Magic/V006/buffmem.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the S100 ColorMagic-1.1-006 design in my own project?
Its repository states no licence, so its author keeps all rights: ask RichCini before reusing the design.
