I have news that Elena Novaretti, author of good software programs such as ZoneXplorer and Power Icons (and a known Pegasos fan and owner) is also present at Webbit Padova with a Pegasos II kindly furnished by Pegasos Italia just for the exhibition event.
We expect soon impressions of Webbit show from Elena, and news about the impact which Peggy II made to italian public.
Wow!!!
After 10 years of absence to important events here in Italy, two Amiga based platforms are there!
More! I have news that the booth by Virtual Works, Ikir Sector, Soft3, Bitplane (with partecipation by Eyetech, ZetaOS and Cloanto people) IS A DOUBLE-SIZE booth.
Very impressive.
And more, seems that (basing upon Ikir statements on the web), there are two Pegasos at Amiga booth...
Amiga has a Very Very strong presence and a lots of opportunities to impact the public at Webbit Italy.
Good news for our beloved platform.

NEWSFLASH :
SW written for AOS does write into unallocated memory (every SW has bugs), and
sometimes they are even supposed to write into system-structures. Making that
imposssible, and thereby protecting kernel and apps from eachother is the whole
point of MP. 99% of all old apps will fataly fail the second your put MP over the
kernel and it's structures.

Yeah, and what has this to do with the number of abstraction-layers involved ?

Lets see, the exec-wrapper and all old apps are within that box, so lots of inter-task-communication can be done without switching back to quark. But lets assume it would happen 100 times per secound and each switch would take 100 cycles. Thats 100.000 cycles on a CPU that just made atleast 600.000.000 cycles ...

It will eat cycles while it is monitoring wether a access to a "moved" mem-area is happening. It will eat cycles rerouting those acceses to the physical address, and no this does not just happen when something illegal happens (just read for what they want to use the MMU).
>>MOS0.4 was released in 2001, and yes it did use parts of AOS3.x (on a binary level).
>>Nothing wrong with that as MOS0.4 ONLY runs on Amigas with OS3.x installed ..
>Nothing wrong unless the software is pirated.
And what has this to do with the kernel they run the SW ?

Noone cares (and noone should care) about your impression. |
