HansO wrote about memory chip malfunction. This could be due to a mistake while upgrading, but also due to electromigration. He also just wrote about the top ten issues, not mentioning all the rest. Malfunctions due to electromigration may be hard to detect. The device just don't work anymore, that's all. Regardless for what reason, what did you expect, the stuff is 10 to 20 years old, even more, thus most people will not care about. So it is unfair to blame somebody who sold you such a computer for selling you stuff which finally went defective after some short time of usage! That's the point. That's why I started this threat.

Conclusion: Support the OCM, you never can be sure that your beloved MSX stuff will go on working tomorrow! |

No, the conclusion is: Modern electronics fails after 3-5 years of usage, old MSX-es still work after 20 years.

But suddenly they will fail! If not due to electromigration, than due to other reasons, depending on how and how often you used it. |

| Well, HansO, none of the reasons of failure you gave is connected to electromigration mentioned by Tanni.
Most of them are rather examples of inaccurate usage, not of hard wearing.

Indeed! MSX and other machines from the 80ties withstand time quite well.
Physical threats are the biggest danger: the user!
But heat is a slow killer, not only for the power supply. And switching on the power causes a short period of time where signals are out of standard values. Also various degradations occur in IC's that will lead to failure. Every device will once fail! |

Many Toshiba HX-10's as sold in the Netherlands are in fact mediocre quality machines. Video is not the best quality since the video circuit was modified for the dutch market from the factory installed UK setting. The Toshiba (and other MSX-1 machines) were dumped in the Netherlands for low prices (350-400 guilders in 1985) after the failure of MSX in the UK market.
Build quality of the HX-10 is also not exceptional: I have repaired many with broken joystick connectors. |

Some years ago, there was a click some minutes after switching off my Sony Hit Bit for quite a period of time. Then, I got just lower case characters and no control characters while printing. One of the lines got cut off by termical stress, I guess. But I wonder why there's one bit permanently in high state. |
