Hello!
First of all I want to thank everybody who help me about slots signals
in several messages. Thank to all!
Now another question:
Recentlly I bought a PANASONIC A1WX MSX 2+ and I have some problems with
it (...)
I tell you:
This computer has only 64 kbytes of main RAM, so I tried to use my
memmory cartrigge (1 MB) and when the computer starts, under the MSX
logo appears something like: 'RAM: 1088 kb', so its seems that the
computer recognize this memmory, but when I try to load any game that
uses more than 64 kb it hangs the computer or appears a message like
'not enought memmory'...
I proved to send some values to the memmory mapper and it seems that
something goes wrong (from BASIC):
OUT (#fe),0
print INP (#fe)
result: 252
And if I sent 1, 2 or 3 the results are 253, 254 and 255 (and the same
with or without the 1MB cartridge).
I supose that the computer takes his own memmory mapper as the main and
ignores the other one.
Last thing, I tried to load COMPASS and it seems that works right, but
only in DOS 1.x, because in DOS 2 it hangs the computer...
Well, I supose that I'm not the only one who has a PANASONIC 2+, so
maybe someone can help me.
I need to know how can I use my memmory cartridge and if someone knows it,
how to 'upgrade' it to 128/256/512 internally.
Thanks in advanced.
Saludos,
Ramón Serna
