From Eugene Palenock → To Valerij Kozhevnikoff 25 December 2000
Hello Valerij!
23 Dec 00 15:02, Valerij Kozhevnikoff -> Eugene Palenock:
VK>>> Damn, the mouse buttons are gone, and half of the keyboard is buggy.
EP>> 1. Quartz floated
VK> How long is he there?
That's what it says on it... Just to see it, I need it
unsolder... In general, probably 10 or 12 MHz
EP>> And if you install a passive (Amiga) mouse?
VK> Where to find it.
If you would like... You can easily find them on the outskirts of Mitinka for 50 rubles...
VK> One button in each half-row does not work.
VK> IMHO, there is a bit in some thread of the buffer that died, through which the bytes are on the SD
VK> are slipped.
And what's the problem? Is it difficult to understand which bit? And then it along the paths from the slot
find which m/s he is going to?
Or do you have an old controller, where the m/s are worn out?
They are like this (copied from mine):
