Toshiba HX10 MSX Vintage Computer

Thanks for looking at my listing for a refurbished Toshiba HX-10 MSX

We have completed the following work:

• Replaced the Composite video board – originally there was no video output due to a dead LVA510 chip on the composite out board.
• Replaced 2 keyboard switches for new, old stock switches for he K and R keys which were not working
• Cleaned the key caps and the cases inside and out – there is some marks on the case but overall, it is really good considering its age!
• Attached a heatsink to a power transistor on the motherboard – this transistor gets very hot and the heatsink helps improve its longevity
• Checked the electrolytic capacitors on the motherboard with an ESR meter – all caps were within tolerances.  Toshiba used very good quality capacitors during manufacturing.
• Cleaned the pins on the VDP chip – these get tarnished.
• Replaced the ROM – original ROM was dead on arrival, replaced with another I had in stock from another parts machine.
• Tested the cassette input loading games with a MaxDuino digital tape loader – all games tried worked perfectly.
• Tested the VDP and RAM with a test cart.  All tests passed a number of times.

The case is clean. And it’s in very good condition considering its age.  The keyboard has a lovely feel and all keys work beautifully.

This really is a nice Toshiba HX-10 64k MSX-1 that we are selling from our collection of retro computers.

Thanks again for looking at my listing, and happy bidding!
