SBC Computer 1988-92 , Motorola MC68000 , CNC application

VIDEO #2: Prototyp SBC( Single-Board-Computer ), Wire-Wrap technology, 1988-1992, based on a MOTOROLA MC68000 CPU running at 8Mhrz.
Application: 3 axis controlled CNC machine. The MICRO Monitor running in 2 UV-ROM's was written by myself and was able to provide Multi-Tasking ( real-time ) with job context switching. Also , some of ATARI BIOS routines were emulated. I used a ATARI Mega-ST Computer with GFA Basic and/or Mark Wiliams C for Software development purpose. The compiled programs were downloaded to this SB Computer and could be executed remotely.
This video should show you the technology how prototyping was realized at this point in time. I also want to show you with this video how extremly changed the chip technology in the timeframe about ~1990. At least , you will find a demo running the final applcation, a 3 axis controlled CNC machine. certainly , this was realized with the final version of a MC68000 based computer in the year 1993.
I appreciate every comment/concern.

Is your design open and available or something you wish to keep private?

This interests me because I decided I wish to use 68k/Coldfire arch for industrial automation computers(for personal machines). There are many reasons that make it still a fine choice (price, main target for gcc, stable technology, etc)

@telesniper2 Hello, much more details you will find on my homepage pdp11gy . com

chapter 3.3 including circuit-diagram. I still have problem to the a floppy-disk where the source

code is on. ( Atari floppy disk ) . Maybe it is media problem. If you have any idea to recover the

data ( via dump program ), let me know this and I will include the source code ( MC68000 assembler )

on home page too. Regards

Doesn't the Sega Genesis/ Mega drive also use a 68000 CPU and a Z80 to control the sound chip?

[PDP11GY]

@theelfkilla Sorry, I don't know but I think a 680000 CPU would /was to expensive. Regards

That's some hard core stuff there... I don't know anybody who can build a computer and an OS too.

@philiptwood  Thanks for the nice compliment , Regards

@theelfkilla

Yes, but the Z80 was only used in certain programs, particularly those which used sample playback for some sounds. In this case, the Z80 did the actual decompresssion.

@kadmany No, sorry can't run. Regards

[theelfkilla]

@theelfkilla Oh and nice work :)

In my case , word mode works with slash and byte mode works with back-slash. That's the way as it it was implemented by myself.
