Guys, If you can burn your own EPROMs you can upgrade to the latest OS by using these files: http://www.strellis.com/Download/dpx1/dpx1v22.zip I copied them from my own DPX-1 ROM set. You need to use 27512 64k EPROMS for both the Lower and Upper binaries. Cheers Chris

Hi, My DPX don't accept my eproms with OS 2.2 I have had OS 1.3 before Eprom programming was done from an online service, so i think that they have done it correct. OS 1.3 are 27C256 eproms with 32k per chip and for OS 2.2 i have taken 27C512 because of 64k per eprom. Just as the readme.txt says Now i am unsure if it make sense to shop the OS 2.2 from Route66. If they also will not run, i have burned nearly 100$. :-( Anyone knowing something about that? Christian --- In emulatorII-list@yahoogroups.com, "Chris Strellis" <synthasy2000@...> wrote:

Hi, I have also OS 2.1 that is the same size 27C512, is there setting near the eprom to switch from 256 to 512? --- In emulatorII-list@yahoogroups.com, "christian.schwank" <c.schwank@...> wrote:
