First time soldering and you jump straight into a surface mount RAM chip? A bit scary

For the digital logic, it should be simple enough if you venture into CPLD/PAL/etc territory, but then it will throw off many regular users who do not have the equipment to program these chips. But if someone is making a bunch of PCBs, they could also supply a pre-programmed IC along with it. |
Yeah, good point, a little CPLD could do the job. I guess somebody else can edit my board and make a 40pin variant if they want.

So it turns out 1.2 kickstart cannot support 1.5MB slow ram and just yellow-screens. But no problem with 1.3 or 3.1, I wonder why. Now I just need a 1MB Agnus to finish it off.
