GVP Combo card A2000-030 EC ver 4
« on: February 01, 2017, 02:54:20 AM »
To anyone who might know...  I purchased the card with a blown SMD capacitor, C52, near the 25 pin SCSI connector at the back of the card.  The accelerator works like a champ, but I have yet to exercise the SCSI feature on the card.  Wondering if anyone has the schematics for this card or knows the rating of that particular capacitor, as none of the SMD chip capacitors are marked.  It's a long shot, I know.  Just hoping...

Absolute on them not being marked.  I suppose I could de-solder one of the adjacent capacitors that are obviously serving in a decoupling role and check with the fluke for capacitance rating...  I know they are a "1210" form factor, just do not know the values.  
 
 Thanks so much for the interest and comments.

LOL... that is the one I bought...  Works fine, and think what Pat intimated to be true, that it could survive indefinitely without the capacitor, but it offends me to leave it "un-fixed".

So appreciate all the discussion.  It will be a week or two before I can validate but will let you all know how it pans out.  I am optimistic everything will be AOK.

Hey,

Just to let everyone know... I got so deep into my SCSI2SD v6 that I set this card aside for a bit and just went with a SupraTurbo28. Just the other day, the gent who sold it to me advertised another one, fully working, on ebay, and it got me thinking again. I had already successfully replaced the decoupling cap (thanks again for all the advice). It really felt like a bad CPU, and I got my hands on a full (not EC) 030 40mHz. Darn thing boots right up and works like a champ now. Just thought I would share.
