Hi,
I want to include the PS2 mouse with the PC keyboard. I have the SW
for the mouse in digital data style. What are the pulses in Forward,
Back, Left Right pins 1, 2, 3, 4 of the MSX analogic mouse? With
this info I can finish the analogic emulation (*) and then the new PC
Keyboard can include : Mouse Analog/Digital connection, one/two
joystick ports and PSG with stereo power amplifier with digital volume
and input for Audio CD... (see LPE-PSGM-V1).
Are you actually talking about analog MSX mice? I don't know about their
existance (and I can't think of how they could be implemented, given the
MSX hardware). So I shall stick to the digital MSX mice.
The mouse is always in one of 4 states, which are degenerate in pairs
(undistinguishable, or at least allmost). The mouse has 4 bytes of
internal memory, 2 of which keep the X and Y movement since the last
readout and 2 which are needed for output buffering.
When the mouse is in state 0, the strobe is 0. This is the state it should
be in when interrupts are enabled, and the mouse is not currently read
out.
Flipping the strobe to 1 sets the mouse in state 1. This causes the 2
bytes of memory to be copied into the output buffers. After a little time,
the low nibble of the X movement can be read out on pins 1-4 (up, down,
left, right).
Flipping the strobe back to 0 sets the mouse in state 2. This state is
degenerate with state 0, because the MSX can only see the state of the
strobe. While being in state 2, the pins 1-4 contain the high nibble of
the X movement.
The same thing can be done twice more. Flipping the strobe sets the mouse
to state 3 and the pins 1-4 to the low Y movement nibble. Flipping it
again returns the mouse in state 0 and leaves the pins 1-4 to the high Y
nibble movement.
A nibble is put on the pins 1-4 with MSb on pin 4 and LSb on pin 1, so it
is in the correct order when read out by the MSX.
I hope this helped you. If I didn't answer the question you meant to be
asking, please rephrase it and I'll try again.

Re: (Joynet protocol)

UZIX processes have priority. You can use a daemon process as a
JUMP driver (as TCP/IP do). The only problem that can arise is that it
will slow down the link (assuming JUMP is a sincronous protocol - an
asincronous protocol will not work, because UZIX JUMP driver will lose
bits).
I understand. It is actually a good thing to give the driver a priority,
because then the user can decide if she wants to slow down the network to
get better performance or not.
So Grauw (you were writing a paper on an asynchronous protocol, right?),
please hurry up and post it, so we can soon realise it.
The best thing (even for TCP/IP) would be putting the driver
inside the kernel (but it can't be done now, due to low memory).
It is good to be compatible with e.g. 64kB, but you could use the system
as in linux, where the user can compile her own kernel with or without
support for all kind of things, so she can choose to have a powerfull
kernel or a small one.
I personally like the idea of a microkernel very much though, because it
can be bugfree eventually. The idea is to have the kernel doing the
resource managing (memory, cpu time) and leave the device managing (vdp,
psg, etc) to the drivers. The drivers should then not have all
permissions, as they do in the linux kernel, but also be limited, so the
kernel doesn't hang if a driver does.
Drivers should be run-time includable and removable (like insmod and
rmmod, but in a more transparent way). I don't know if you feel like
including those ideas into UZIX. I just think it is a good idea, because
it gives the possibility to put drivers like tcp/ip in the kernel, without
wasting the space/opening possible security holes for the users that don't
use them.

Re: MSX connected to a TV-card
- Original Message - From: "Richard Gerrits" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, September 26, 2000 9:19 PM Subject: MSX connected to a TV-card Hello I have connected my 8250 to a TV-capture card (bt878), but I have some vague problems. Basic and most games work fine, but with SpaceManBow, SolidSnake and some other games, the grapics are kind of double. It looks like the capturecard has some trouble with the synchronisation or something like that. When I connect the msx to a TV (also through video out) the graphics are normal. Anyone has a solution to this? The Bt878 based cards should be able to do multi-norm, i.e. also NTSC. But maybe you should choose PAL-M, this should be 60Hz, but with color at 4.43 MHz. Try finding a setting for this. Greetz Patrick Problems? contact [EMAIL PROTECTED] See also http://www.faq.msxnet.org/
