Entry 2nd July 2020: Post 1: Yamaha MSX - CX5M Music Computer.

Yamaha MSX - CX5M Music Computer.

I had intended checking over the Yamaha MSX a month or so ago when
I was looking at a few other MSX machines, but somehow misplaced
the power supply, which is unique to this computer.

What makes the CX5M special is the built in SFG-01 sound module and
the special cartridges that turn this MSX into a musical instrument.
The computer came with a special keyboard, which I don't have so
I have never tried out the software provided.

I do like how the sound module slots into the base and gives ports
for both midi and musical keyboard. Fortunately I do have a couple
of the cartridges for the computer so if I could find a suitable
keyboard I could check out how she performs. For now though she
boots up as a pretty standard MSX machine for the day. For her age
she still looks as good as the day she was made. Not bad.

Yamaha CX5M Music Computer made in Japan in 1984.
Utilises Microsoft Extended BASIC ( MSX BASIC V1.0 )
Runs on a Zilog Z80 at 3.58 MHz and has 32 KB RAM ( up to 64 KB )
Sound: General Instruments AY-3-8910 Programmable Sound Generator
plus built-in SFG-01 Sound Module. FM sound generator.
The computer is fitted with two cartridge slots.

To run this MSX machine you will need the external PSU. Fortunately I
eventually located mine. Phew !!
