Re: [colorforth] What's new?

[Nick Maroudas <alice@xxxxxxxxxxxxxxxxxxxxxxx>]

Dear Jason, 

Your account of Forth on Z80 brought back happy memories. In
those cases where I knew enough about the hardware to replace
Basic by Forth, the latter ran 10 times faster. I read
somewhere about a Forth that was almost wholly constructed from
BUILDS/DOES.  Which reminds me:  what is the CF equivalent?
(Perhaps a compiled POP plus yellow/green instructions?) 

My replies to your comments are numbered below.

Reply 1:  For the EV board

Reply 2.  There is a blog

Reply 3.  Jeff Fox said long ago that there was no color.

Reply 4.  I believe (subject to correction) that Chuck has such
a thing.

Reply 5.  At that price and at my age, I have to consider. 
Perhaps the price will come down in the last quarter, when they
start to manufacture in quantity; perhaps by then I'll have
some
more spare cash and enthusiasm for new project.

Reply 6.  CF now has very little machine code, once you have
booted it. I guess that there is enough USB source code in CF2
to run native - once one understands the USB/BOOT & TCP/IP
protocols.  But I must confess that I have abandoned hope of
doing this myself in the foreseeable future.

Reply 7.  I found CF useful because it gave me control of PCI
bus and a 3 fold increase of speed - just what I needed to test
my onesy notion of building a synth with high speed parallel
DAC
at a time when commercial soundcards were limited to 44-48k Hz.
(See my reply to Mathew Vaded).

Caritas,

Nick
