Hi, I developed a graphical developement environment for PDP-11's. It's name is "PDP11GUI". Since it is spreading on the net already, I'm forced to announce it early. Status is "mostly beta". I begun building it in spring 2008 as a tool for my own 11/44 restauration project, but it quickly developed it's own momentum. Key features: - interfaces to 11/44 and SimH, ODT interface is under development. - interfaces through physical COM ports or via telnet. - visual display and manipulation of memory content - symbolic display and manipulation of I/O registers and bits. - can assemble and deposit MACRO-11 programs - can Run/Stop/Single step through code, displays execution position in source code and/or disassembly - can also be operated through photorealistic simulated PDP11/70 panel. - I/O page register scanner - Memory loader - 11/44 micro code display - MS Windows MDI application. - Free for non-commercial use. It is free for non-commercial use, download at http://www.j-hoppe.de/PDP-11/Resources/setup.exe Mandatory documentation at www.j-hoppe.de/pdp11gui.html Enjoy! Joerg Hoppe
