PS/2 8530 Mainboard Component

[schimmi]

Hi there,

i recently bought a 8530 with 8086 CPU (not the 286 variant), however the seller decided to drop an unsecured hdd inside the case before he sent it to me. Now one of the crytal oscillators is completely smashed. No big deal replacing it, but I can't read the value on it anymore.

Is there anyone also having an IBM 8530 w/8086 CPU and can tell me the correct value of the osci marked Y3 on the board? I only found pictures and diagrams of the 286-8530 boards

Thanks in advance,
Stefan

Googling it gets me to http://ohlandl.ipv7.net/8530/8530-286_Planar.html where it says Y2 = 25.175MHz crystal... oh crap that's the 286.

From pictures I can only see something blurry but it almost looks like it's the same crystal there... something .175MHz

Yep, same: 25.17500MHz: https://www.ebay.com/p/IBM-Ps2-8530-Computer-System-Board-61x8823-61X8825/1700352186

Y3 is 48.0000Mhz BTW: https://mcretro.net/wp-content/uploads/2012/09/IMG_7172.jpg

You're welcome

Hey,

many thanks, thats it! I googled for hours and couldn't find such a picture. I'm well aware of Ohland and all the superb MCA Mafia pages, but they only mention the 8530-286 model.

Thanks again!
Stefan
