[M3devel] Yet Another OS in Modula-3, AVOCA, in x-kernel

[Daniel Alejandro Benavides D.]

Hi all:
Have a look at the real workstation Window System problem:
http://en.wikipedia.org/wiki/Acorn_Computers#cite_ref-23

Having said that, still the Window system in the A500 was ahead of its time so you might say it could run in BBC-Micro systems, like 32016 as VDU across the TUBE ULA but HW backwards compatibility as well!

There is a book refereed to that as well who details the Archimedes A500 architecture If my memory serves still:
http://www.zxdesign.info/book/bookAnnounce.shtml

See other projects have included this technologies as well:

Thanks in advance

Hi all:

Well indeed, that they sell like 200 copies of ARX Acorn/Olivetti (besides 100 or so developers on the developer machines):

If so, they didn't release because of the cost issues were very important as you can see in this 01:30 video

Anyway the history behind that system is on this machine:

"CPU Clock8MHz"

alt+f4.

 





It seemed that the Acorn had not released because of cost issues rather than marketing reasons, since the selling machines were not ready for its system:

http://acorn.chriswhy.co.uk/docs/Acorn/Tech/Acorn_FastA500s.pdf



But the compiler (I think called CAMEL) was not to blame, since it had a pretty good performance in terms of the chip (yeah it was but even not that fast for such machines cost relation). Later it wasn't released for some other reasons (would I know why, I guess they just took C route).





Thanks in advance
