Hello people,

After removing the screws (also there are two inside the bottom slot cover), you have to open three latches located at the sides.

It doesn't have a latch just In the corner where the A/V CASSETE outputs are.

To open the latches, you must press the top side and pull the bottom side of the cover, while applying force in way to detach top from bottom.

To release the keyboard, you must release the two green wires, and lift the FPC connector to release the strip of the flexible PCB.

Cool! I just dumped my just bought Casio PV-16

So, this MX-10: TMS9118, NEC Z80, AY-3-8910 and some weird chip with 5K4 HG61H0BR02F JAPAN on it...

Did you also dump the ROM? Perhaps you can also run the usual tests, so ident.bas and msxmem2.bas.

I ran all of that using a slotexpander, memory mapper and external diskdrive on the single cartslot the PV-16 has.

Also, I confirmed the polarity of the power connector. It is Japanese standard, what means negative (GND) at the center.

That was bought as "junk"... This unit loose weighs about 1.0Kg and can be shipped as Small Packet, which is cheap.

Next I will try to power it on. Cross your fingers, please.

Does anybody have, or know the internals of that external cassete Interface ?

external cassette interface!?

What is the difference with the PV-16 anyway? PV-16 is a cheap-ass MSX1 with 16kB RAM, a standard ROM, no printer connector, cheap keyboard, joystick controls on the keyboard, no reset switch, single cartridge slot, composite/sound out (RCA) and TV out (RCA), cassette port ("MT") and 2 joystick controllers. Very gaming oriented.

Yes, this thing:

I've also got a PV-7:

Does that heatsink for the 7805 need to be so big ? I don't think so...

So, the MX-10 does not have the tape interface which the PV-16 does have?

The PV-7 is also very interesting, as it has only 8kB of RAM!

I'm very interested in making machine configurations for openMSX for all these Casio games! Will you help??

I think MX-10 doesn't have to dump it.
Because it uses as Japanese Standard MSX version 1.0
BIOS is same as CF-2000, PV-16
Instead run this statement on MX-10.

A=0:FOR I=0 TO &H7FFF:A=A+PEEK(I):NEXTRINT A

The result must be 3858008.

So, what is functionally/technically the difference between MX-10 and PV-16?

Is it the missing cassette port on the MX-10?

Just checked the MX-10 rom and compared to PV-7 or PV-16 rom (a French fan had some time ago dumped the PV-7 for blueMSX : the rom is exactly the same in PV-7 and PV-16).

The MX-10 rom is slightly different, here's the comparison made in WinHex :

That was my fault...

I did'nt protect the RAM... These zeroes were put in there by MSX-BASIC Interpreter... Now I've extracted the ROM with old good GETROM.BIN
