Retro computer of the day – Toshiba HX-10 MSX
Old-Computers.com says the following about this machine.
The HX-10 was a classic MSX 1 computer with no special feature… But it was one of the first MSX computers to be exported outside Japan. It met a good success in UK where it can still be found in flea markets and boot sales…
Apparently there were several models of the HX-10 (D, DP, DPN, F, E and S) depending on the country they were sold, but it’s not clear what’s the difference between them so far… The HX-10 DPN and F had a Scart video output instead of RF/composite outputs, and the HX-10S had only 16 kb RAM.
In its native country, the HX-10 was also named Pasopia IQ to fit in the Pasopia family developped by Toshiba.

Ive owned my HX-10 for about a year now, and I think its a good little machine. Sadly, I only have 3 games on tape, and no cartridges.
Do you or did you have one of these MSXs? What games would you reccomend – please let me know using the comment box below.


My school used to have 2 or 3 MSX computers (in amongst the countless BBC B’s) Sony HITBIT IIRC. We had them in the IT Lab and they controlled a robot arm. That’s all I really remember.
MSX was not very popular in my neck of the woods (South Coast) and the ones at School and a couple of cassettes at a local Computer emporium was all I ever saw of them.
