Cool My boards arrrived

My boards arrived yesterday! I also got a good deal on our local ebay (marktplaats) for some SIMM sticks so I am ready for some soldering.

However I am a bit puzzled about all the different jumper settings and configurations:

  • First of all, I got a rev B board + Gary adapter. It has room for 4 RAM chips. However, the schematics (Eagle files) on your website are for rev A I guess as the schematics show only 3 RAM chips.
  • Second, ideally I want to expand my rev 5 A500 to 1MB chip (by modding the mainboard and replacing Agnus) and 1,5MB slow. This is possible right? How do I need to set all the jumpers then? The rev B schematics would be helpful in that respect so I can maybe figure it out on my own.

The PCB looks very nice BTW and I am looking forward to building this nice little expansion
Nice work
