Why not 64 bits with double registers, as the Z80 makes 16 out of 8
bits.

Why not memory mapped I/O? dispite the HW problems, it gives great
sofware advantages. Imagine, all memory instructions also work on I/O.
Also reduses the instruction sets with about all I/O instructions.

all of the above in the processor??

Is that all??

Some of the screen modes:
HDTV
Pal PLUS
3200x1800 (wide screen: 16x9)
other direct tv definitions like pal, secam, ntsc etc.

And paralel printer input!!

Please scip the modem and get at least 4 serial ports.

That makes 5 serial ports.

With what protocol? Have a loook at the RC6 code

The above are some remarks I have while I read the mail. All I can say
at this moment, Sorry but I don't buy your machine just because to me it
looks as just an other machine. I have seen several specs for several
machines. I say: have a look at all machines as in (MSX, Atari, Amiga,
PC, and all others). Also have a look at different computer
architectures, don't forget to look at professional ones like
ultrasparc, pa-risc, vmebus systems etc. For I/O there are also more
than one: you mention serial and paralel, don't forget SCSI, IDE, I2C,
and there are many others. Pick out of it what ever you like and dream
on. I bet your favorite machine does not resemble my machine.
I don't want to see what will be in your computer, I also want to see
what will NOT be in your computer: Just to see if you have had a look at
is and why that is not in your computer.
