Was needing NTSC 500+, maybe I *can* use PAL?

I bought an A500 from eBay last week.  I asked the seller twice to make sure this was the A500+ model with the Rev 8 mobo, and twice he said it was.

I got it today, it's a Rev 6a.  Don't get me wrong, this is a pristine system and, from the looks of it, I am the first to crack its shielding.  The clamshell itself had signs of having been opened already.

So, now I have a 500 in great phsyical condition, with power supply and various other peripherals, and said to be working (haven't tried it yet, honestly.)  But it's of no use to me as I was looking for either a spare to my existing 500+, or a system to supplant the current 500+ and turn it into a spare.

Does anyone out there have an NTSC A500+ with the A501+ expansion they would be willing to trade, or even sell?

Interesting developments.  Last week I ran SysInfo on my 500+ to see if it rated the 50MHz Derringer at the right speed (rates it 51MHz, FWIW.)  I noticed that it determined the system was PAL.  Odd... I don't think anything of it because for many years it was working fine as an NTSC system, right?

Well, the signs make sense now.  For instance, many games and demos I run on my REAL NTSC systems (2000, 1200, 4000) always seemed to have different timing, along as some music.  Nah.

Tonight I'm having a peek around the custom chips area of the Big Book of Amiga Hardware and I think about the 2MB Agnus.  There it seems that there were two version of the 2MB 8275 Agnus used in the 500+, PAL (-01) and NTSC (-02).  Hmmmm, you thinking what I'm thinking?

I crack the hood tonight and, yup, my 500+ has a PAL chip in it.  Has always worked seemingly fine under NTSC, but my memory says to me that I never ran an OS older than 3.1 on this system, so NTSC monitor driver only.  Does that make sense?

But it's definitely running PAL -- I have it connected to my FP2001 LCD monitor which shows "PAL@50Hz" in the early startup menu.  Well, I'll be darned.
