Micro Craft Dimension 68K, currently with a hack because they're doing something we don't support with the disks (double-stepping assuming a double-density disk in a high-density drive):

I haven't looked at MAME in quite a while, but I have to say I'm thrilled to see that improvements to support for ridiculously obscure hardware continue to appear.

One step forward, then find out the sound program contains no valid Z80 code.

And we got a proper dump of the sound program. It's weird - I don't know if it was made with some kind of compiler or they gave it to the intern, but the code's very strange.

De-Skeletonizing the m3.cpp driver:

Rescue thread is here: http://www.vcfed.org/forum/showthre...LSI-M-THREE-computer-restoration-project

That monitor ROM is unofficial, and there is no other software as far as I can tell.

I love seeing machines I've never heard of coming up in MAME. Hopefully some software will turn up for it.

This is the Kyber Minus from Kyber Calcolatori, it's a CP/M clone thing.

[Linked Image from i.imgur.com]

The owner has provided a boot floppy image for it but am having trouble getting it to even attempt to boot, a ready signal from the floppy drive should generate an interrupt to trigger the boot process. I have a schematic so may submit as is in case anyone else can make more sense of it.

No idea what this thing really is or even if it's complete. Only source of info is this video:

I've been in contact with Steve Hunt, who dumped the m3 ROMs and wrote the replacement monitor ROM. He gave me his custom CP/M floppy images, so that I've been able to hook up floppy support:

Still no official software, but at least the machine is usable now.

I also have a new version of the monitor ROM that supports booting from IDE.

G.T. Block Challenger (1978 arcade game) dumped by chaneman.
I was unable to find where it reads the paddle (or maybe ball/paddle collision detection)

Neat. Did it actually use a green monitor? Most 70s games were black & white.

More likely a green overlay (it is using a color overlay on MAME)

Having researched Sun Electronics/Sunsoft for five years, I am really happy to finally see that G.T. Block Challenger have been dumped. I made that Fandom wiki page. The text is not very correct. I am almost finished with my first magazine about Sunsoft, where I cover their old games. So, I will be really happy to make changes to the text so it no longer says it is lost. And some screenshots will be great too.

The Regnecentralen RC759 can now boot one of the floppies:

Keyboard works, and the 82730 was much improved too.

There are random floppy I/O errors though and other disks don't even get that far. I'll probably take a break now, the 186 isn't really my favorite CPU.

Some stuff you can do with the recently promoted Mac drivers. All of these are fresh installs from floppy images using the new floppy emulation.
