Site visitor “Katz” has advised that George Philips has released v1.5 of his TRS80GP Emulator which is available for download from either George’s site or the emulator page.
George describes the emulator as “built primarily as a development tool for software written for real TRS-80′s and for experiments in improved emulation fidelity. It can load programs in .cas, .hex, .bas or .cmd format directly but has no disk emulation nor can use use CLOAD or SYSTEM to load .cas files (as in most normal emulators).
I would say that this ‘emulator’s strength is that you do not need to set up a ROM (it is built in), import files onto DSK/DMK’s, have boot disks, etc. If you have a /CMD file or a /BAS file or a /CAS file, you would simply execute the emulator FROM A COMMAND LINE, and your program would run. No fuss.
More details can be found on George’s page but running the emulator with a -? flag will also provide details.
