HP 28s rom dump with 50g

[JDW]

Bart, since not one else replied back to my previous post, it would appear you are correct. And the fact, illegal or not, we cannot find a usable 28S ROM online either seems to confirm that pretty much one one has ever done it. I did find one ROM online, but it has a <script> at the end and even after deleting that and reserving, it won't work in the EMU42 simulator (28S displays but clicking ON does nothing).
