Vampire connector troubles

My Amiga 600 with Vampire V2 is giving me a lot of troubles. When using this A600 I had many crashes, freezes, reboots. It turned out the processor socket of the Vampire did not very well fit on the A600's CPU. It would come off too easily.

After a lot of removing the Vampire and then pushing it on again only made things worse. Then I decided to replace the CPU socket of the Vampire. It did not give any improvement. What's worse, the new socket cracked quite soon. As many other A600 owners seem to have no problems I asked some member of a Dutch Amiga forum to help solving this problem.

I sent him the A600 motherboard with the Vampire. He first replaced the socket again and it turned out that this would not solve the problem of the Vampire coming off. I had an A600 with a different CPU or there had been done some rework: the Vampire would pop off very easily no matter. So the guy offered me a different motherboard that seemed to hold the Vampire better than the old one.

But after a lot of testing I only can say that pushing a socket on the processor is still not ideal and prone to problems. Besides that it is possible that crashes also originate from the OS (Coffin). Not easy to determine.
Having an A500, A1000 or A2000 with a Vampire would be a much better solution! 

The Vampire's price doubled since it's introduction. So I will stick with the A600 and try to make the best of it. That means: open it up often to push the Vampire!

Amiga 4000 motherboard overhaul

Last month I discovered that the sound of my Amiga 4000 desktop computer did not work. The battery backed clock also did not keep the right time any more. Time to get it overhauled. As I do not have enough skills for this I asked in the A1k.org forums for someone to carry this out. Luckily it was the user milo who wanted to do that for me.

As you can see from the pictures below (before and after) he did a terrific job in a very short time and did'nt ask too much for it. Recommended.
He used ceramic capacitors in stead of the usual electrolytic ones. These ceramic capacitors cannot leak. He also replaced the battery with a coin type.  I'm very happy with the result. Thanks milo!

Internal HDMI cable Vampire V2 Amiga 600

Every owner of a Vampire V2 for the Amiga 600 knows the problem: the Vampire has HDMI out but the positioning of the connector is not very useful. The floppy is in the way using normal HDMI cables/connectors. Besides, normal HDMI cables are way too inflexible.

Some time ago I stumbled upon this. Not cheap but promising. So I ordered one and tested it. I think it's a very nice solution to the problem.


In the mean time I have desoldered the RF-modulator from the A600 motherboard. So I can now find a way to attach the outgoing cable connector to the motherboard.

Repaint job PV544

It was time to get the PV544 (from 1961) repainted. It has been sitting for more than 20 years in storage without any maintenance. The paint was so dull and I couldn't get it to shine again. So I invited some paint shops to make an offer.

Now, the car is under treatment. The job started in august 2016 and will take several months to complete. I will get this post updated every now and then.

Most of the body, mud guards, doors, hood etc. have the paint be removed and a primer sprayed on.
