I still have plenty of school stuff to do, but much less than before, so I am taking on some projects again.

I have plans of porting the operating system I have on my cbs6000 and z820 to the visicom. Because these three machines have different cpu architectures the OS has to be written from scratch every time.

I wanted this computer to be on par with modern microcontrollers, so I stuffed as many peripherals in it as possible. I still have the address space to add 4 more peripherals on the I/O board. I don't have enough physical space though I can maybe fit stuff like a realtime clock on it.

I wrote up some documentation today. For those who are interested in lots of tech talk:

Also some new pics:

That depends on the screen I guess.

Depends on the task at hand. When I need to do stuff close to the hardware I prefer using asm. When stuff gets more complex I usually move on to C, but sometimes I just work with asm to keep things consistent.

I have done a bit of asm programming for the cse in the past, but not much else yet.

I finished porting the monitor and it works great! It's just like the one on the CBS6000. I learned a lot about the z80 in the process.

Yeah I should get rid of that That should have been taken down after I fixed the bug.

I am busy writing a monitor program which allows me to poke around in memory and debug stuff. I based the monitor off the one I have on the cbs6000 computer.

I ported the bootloader I made for the cbs6000 to z80 asm. It works great

I got the serial output to work with the PC16552D UART chip. There were some dodgy solder joints that caused problems with it, but I tracked them down and resolved the problem.

It prints characters at 960 Bytes/second right now, but it can go up to 125kByte/second.

Yeah I figured. In europe used (and new) consoles are more expensive compared to america.

Over here they are dirt cheap. Europe ftw.

Not really. Broken c64's are worth €7-10

This is intel's super hero:

I wonder what ST, TI and Microchip are going to come up with.
