Having a daughterboard in a PAL machine is very unusual. Have you cracked that case open? If not, would you be willing to (and taking a few pics)?

It's certainly possible - especially considering that S/N - that you have a very (and pretty rare) early PAL A1000. Those were based on the NTSC motherboard, which would explain the daughterboard. In general PAL machines didn't get those.


Hi Intric8,

Thanks for the reply! I did open the unit up last night and got some photos. Will post once wrapped up at work this evening. It's a RevA (327049-01) motherboard with mainly early 86 IC's (some late 85 too). Any pics in particular that would help?

Regards,

Ross.

Hello

Living in Norway, I have a PAL machine with dautgherboard. SN : XM 4119348

Will check the motherboard revision in details later.


I have installed the kickstart adapter I downloaded and produced from this site.

Allow me, those are not rare at all. For several months in 1986, all A1Ks sold in Austria (and I assume in the whole of Western Europa) were semi-PALs, ie PAL-Agnus, but NTSC-timing, and a piggy back board. Considering the end of the A1K in 1987, I'd say that at least one in three sold was such a PAL-hybrid.

I think I have one of those hybrids 1000 too here.

I'll look at my serial tonight (and will take some photos too).

Let me rephrase.

In the US, those are very rare. And in the EU, they were the model of A1000 least sold (but aren't considered rare by some).

I wonder if they would be compatible with the Rejuvenator? I have a strong feeling they would be, which is kind of cool. Matching a Rejuvenator with one of those in 2019 would be a fairly unique setup.

Anecdotally, the A1000 owners from the EU that I've talked to about the Rejuve have always expressed disappointment that the daughterboard was required - meaning they didn't have them. That's where I was basing my previous unscientific assumption of rarity.

Looking forward to your experiments and pics, @batteman!

I must admit that I'm not sure it's a PAL version (I'm a newbie on A1000 even if I own mine since years... :oops: ).

I have the serial XM4013714N (notice the "Commodore" on the sticker and, more interesting, the deutsch sentence on the left ! Google translates it as "radio-interference") :

And this is the inside of my 1000 :

Hope those photos can help a little bit ;)

So this makes me wonder; what is the effect og NTSC timing on a PAL machine? Faster than a real PAL machine?

Funkenstört, would be more like 'shielded' after the regulations DBP-Vfg.1046/84

Speaking of rejuvenators :) Any updates on the PAL cloning?

The man who successfully rebuilt the Rejuvenator board - Joethezombie - got crushed by an insane amount of work with his job the last several months and has barely been able to come up for air. It's been disappointing but unavoidable.

He has let me know recently that he hopes to get back to the equations soon, but the soon is undefined.

We're starting to discuss some backup plans to potentially two (or three) boards being built simultaneously.
