Individual MAME components are mostly BSD; the project as a whole is GPLv2 because we have some GPL components. In general we've been reducing reliance on GPL code where possible though.

random roms for unknown kaypro computers, to be checked, per Robbberts comment in the drivers ...

x.bin
That file comes from here. It's only 4095 bytes, so I've padded it with 0x00. It's booting e.g. the Kaypro 10 "G" reload disk, the sign on message is

81-x015.rom
If you plop this ROM into the Kaypro 2X driver, you get this picture. The ROM wants a "U" CP/M version, but this displays a BDOS error at the moment.

rom19ee.bin
This is from the same source as x.bin. This ROM also needs padding to 4096 bytes, it's almost identical to the default Kaypro 10 ROM.

Just one cautionary note about Kaypro 10, in case it's not already known. There are two different harddisk formats that I know of, as hard-coded into the ROM (BIOS) code. These formats are not compatible and I know of no upgrade strategy (let alone a downgrade one). So if you have a working harddisk image on the original 10 (e.g. ROM 81-302c), then update the ROM to the Universal ROM (81-478a) you will lose your harddisk data - possibly permanently (depending on if anything tries to write).

I've tried to pull together some data on various Kaypro models, ROMs, and CP/M versions here: http://sims.durgadas.com/kaypro/kaypromodels.html. I can't guarantee it is 100% correct or complete, but it is based on experimentation with available ROM and CP/M images.

I have gotten cleared to view the source code and contribute to MAME. I still won't be able to dedicate much time to it for at least a month, but could start to get oriented. I did not see an obvious link to the source code, where is the repository? Any high-level introduction available, for both MAME as well as the Kaypro 10 components?

Thanks,

Thanks. got that forked/cloned. I presume S.O.P. is to commit changes to my fork and then generate a pull request.

How do I build a Kaypro 4/84? I was trying SUBTARGET= but there does not seem to be much in the way of subtargets - or else I'm not doing that right.

Code
make SUBTARGET=kaypro SOURCES=src/mame/drivers/kaypro.cpp


If you specify SOURCES it dynamically generates the subtarget for you.

OK, got something to build. Now just need to figure out how to configure machine. I've got ROM and diskette images, but will have to learn how to get those selected. I'll spend more time on the documents. RTFM
