I was given a Toshiba HX-20 a few days ago. I have a few doubts about this unit.

1) The machine itself uses a 8-pin recorder port. Is a DIN5 connector compatible with an 8-pin port?

2) The unit tends to get hot (but still in the accepted range of heat) after 30 mins of simple use, specifically the component I highlighted with the red square:

I believe it is a MOSFET, but I didn't pay much attention when I opened the unit to clean it.
The question is, could this heat affect the 2 capacitors behind it? Would it be a good idea to add a small fan, or it is not necessary at all?

3) Besides cassette, what other data I/O options could I use? Is there any connector to use in the general port to input and output data?

4) Is there any kind of hardware failure that tends to happen with this unit?

Thank you beforehand.

Have a look here:

There are actually 4 variations of the HX-20 targeting different regions.

I don't know much about this system, but its predecessor, the much more common HX-10 is known to have overheating problems if you search the forum.

That's a cool machine. You can find the pin assignment of the standard cassette port on the wiki of this site.

You can use any storage for MSX via the cartridge ports. See also https://www.msx.org/wiki/Category:Toshiba_HX-20
