3.1 ROMs on ebay....

[djbase]

I have also had sets like this, which are indeed EPROMS with a full length sticker on top:

Vesalia's details page no longer shows chips like that, but instead they have the MX Mask Roms.

Another set like that:

These are original Kickstarts (they were sold with a kind of certificate), all other labels are selfmade (except laser of course).
