is there another limit above the 137gb barrier?

Ah well, thanks Philo.

I'll keep looking.

Finding one that still has everything working seems to be a challenge.
Too many years sitting in the bottom of the closet.

I've been going retro - wanting to play with a Z80 again.
I've laid out several boards - trying to get the right mix of
power and simplicity.
My latest is getting pretty close to what I want.
But cross assembly and all the hardware support (like eprom burners)
gets to be a bit much on an XP machine.
Too much like work!

I thought maybe a native code development system would be the way to go.
The Kaypro is perfect for that.
If you can find one still working...

BTW, it looks to me like this group is mostly x86 clone builders.

Anybody here still do chip level design???

The Cambridge Z88 may be a possibilty worth looking at - they're
still available fairly cheaply and can burn EPROMs with a simple
adapter. ISTR seeing an assembler available so you could do all
the work on that if you really wanted.

However - it _is_ a lot of hassle no matter what tools you use
(although command line tools and make speed things up a lot). Why
do you think everyone has moved on to mpore modern MCUs? I tend
to use MSP430s for most of my new stuff - things don't get much
more convenient than in-circuit programming, debugging and
reprogramming.
