Dear member,

I’d like to test a 58MHz osci in my old 386er board. But as you might have guessed I’m not able to find such part on the market. I found 55 and 60 so far. Any idea where to get such piece or how to achieve a 58MHz frequency signal?

Thank you.

Digikey has 59Mhz thru-hole "oscillator" but no 58Mhz nevermind

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

User on here called galonopu has developed a multi setting oscillator module Re: The World's Fastest 486

edit: note that the site in his sig only gives a table of the "normal" frequencies, by putting other oscillators in the multiplier module it will get different ones... meaning that there's about 6 lower value crystals that will give you 58ish.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

Great idea. Thanks. Unfortunately shop cannot checkout / accept payments.

I found a even better alternative here with fine adjustable and programmable frequencies. Unfortunately the link to the product won’t work anymore. I asked at the shop.

This one is close enough. I've bought from him several times and it was always a good experience.

Just look for the same thing on the same site and you'll probably find another seller that does ship to DE.
the link does ship to BE, but i've encountered others as well which do not ship to your country of origin and as usual other sellers have the same thing and do ship to your country of origin

Thanks to all. I was indeed at first searching for it on ali as I also received my 55mhz part there.

What I learned now is it’s worth to look via vpn as well.

I couldn’t find any other reseller there delivering to Germany but I will do it then via a friend in BE to / via BE.

Thank you all!!
