It is normal. Boards found in Gorgar usually look like this. WMS must have realized they needed more bypass capacitors. I think there is one more across 5v and ground bodged soldered right onto traces like that.
Also beware that one electrolytic cap is marked with the wrong polarity on that first version. It is 1uF near the amp. Some of these very early sound boards are found with a white silk screen layer WMS was never using in that era which is kind of interesting. Yours does not...
