Wow!  Holy nostalgia, batman.  I got an email that you'd tagged me.  My login for this site hasn't worked for a couple years, and honestly my A500 has sat in a box since we moved five years ago.  Life and work got in the way, you know how it goes.  I guess screenshots on this site got purged a while back.  So I thought "What are the chances I still have any screenshot?"  I looked in my Google Photos and searched for "Amiga", and nothing helpful came up.  Then I searched for "Startup-Sequence" and lo and behold, a screenshot of my Startup-Sequence from December 2017, and another from August 2017.   ;D  Obviously you'll need to adjust the parameters based on your amount of memory.

I don't remember how I even knew to set this up.  But I do remember that with the VXL + GVP Sidecar + MegaChip my A500 had a total of 18MB of memory (8MB 16-bit fast, 8MB 32-bit fast).  It worked well for a long time.   Years.  But I think one of the last times I used it, something wasn't working anymore.  I think maybe I fubar'd the VXL memory sidecar by overclocking the board.  Or maybe I'm just completely remembering wrong.  In any case, I hope this screenshot helps!

Thanks :) I have just tired VXL30 on my A500 but tog GURU while booting from 030. It booted fine when 68000 was used on the VXL card. I think I need to get a proper contact with the socket. I need to solder a new one as a first step. My VXL30 came with 33mhz cpu and 32mhz oscillator. I think rather uncommon setup? It is version 3 of the board.

Sadly my VXL30 that I just bought is dead. U19 PAL chip is gone. Hot as surface of the sun.
01-901-U19

Does anyone ever tried to read contents of those PAL chips? Maybe somebody is able to?
Willing to pay for this. Thanks for help.
