Re: QuadSpeccy on ReVerSE-U16
@vlad - now it runs...
640x480@60hz
but i have some problems with cores 2-4 (in attach 2 images)
If i press all reset all, the 2-4 cores "reset" to reset server 0.19
its like this? or should the core boot all the spectrums?
can you send a zip file with files I should have in sd card to use NMI button? its the same files used for zxuno and similars?
Thanks

Re: QuadSpeccy on ReVerSE-U16
well...
it works
but after a while the board is hot... it's normal?

Re: QuadSpeccy on ReVerSE-U16
Yes, it is normal. You can put the U16 sideways on one side vertically, for better cooling.brunosilva escribió:but after a while the board is hot... it's normal?

@vlad - maybe i will buy a cooler and place it in the fpga...
Possible directions for a 4-core ZX machine?
Silly question time:
[1] Are the 4 cores totally independent of one another?...
[2] IS there any way of passing information between the cores...?
[3] Have you considered the possibility of using a shared memory space or selecting ports to perhaps allow each core the ability to communicate with each other?
[4] If the above is feasible, would it be possible, in theory, to take an existing open ROM, perhaps one of Andrew Owen's (eg: SE BASIC) and tweak and design it specifically for the purposes of multi-core processing?... To create a ROM or OS for passing info back and forth between itself and other similar OS cores, basically a ROM for connecting to similarly configured systems...?
[5] Could such a OS/ROM form the basis for a new type of ZX machine, a ZX "cluster" or parallel processing machine...
Any thoughts in this direction?...

Silly answer time:kgmcneil escribió:Silly question time:
[1] Yes, cores are completely independent of each other, except for devices of interaction with the user (keyboard, mouse, audio, tv..).
[2] Yes, by means of a specially allocated for this general memory address space and I / O ports.
[3] Yes, such an opportunity was considered, but due to lack of software support at the moment is not used.
[4] Problem in the absence of a qualified software development team, and yes, there are no problems with the implementation of the multiprocessor system.
[5] I think everything is possible.

Re: QuadSpeccy on ReVerSE-U16
Impressive work on the DivGMX...
Just to clarify, when you say:
I will admit that it would take a bit of vision to come up with ideas for software to utilize such features... Perhaps if one started from the basis of something that already exists as a jumping off point, then maybe we wouldn't have to reinvent the wheel...
...which of course begs the question: Is there anything out there already for the ZX that allows for cross communication across ZX platforms?... [Does anyone know???]...
Just a thought... It seems a shame to have such a wonderfully unique feature and not find some clever way to exploit it further...
Thanks for the video clips by the way, I didn't know of your DivGMX project till now...
