You may compare it to current PCs, because it runs on your current PC, but the exceptionary role it once played, and the tremendous efforts for the design of the original system, and its complexity on hardware level all might not be tangible.ДЄnyway, we at least tried to make the copy as close to the original as possible, and it took more than a year to complete the work.

You may think you are running the software on a real system, but it isn't the real system. As I have stated at another place, emulators tend to demystify/profane the real hardware. Last but not least, by writing an emulater like this you gain a near perfect understanding of the object you are dealing with.Д«ut, there are also drawbacks. Also, an emulator may be used as reference when trying to troubleshoot a real system. This can make software development, debugging and testing on the system in general much more convenient. Original floppy noise can be added, and much more.ДЄs with every emulator, you can use the HP 9845 emulator to check HP 9845 software on a guest system without the real hardware. Mass storage media are simulated on a magnetic flux level. Also the display can be tweaked to give a good impressions of real cathode ray tubes, even on LCD screens. Every interface and bus slot is emulated towards its specs. chrystal clocks provide exact timings, every standard processor, controller or ASIC chip is emulated on its own). Mostly, the real hardware is emulated on a really low level (e.g. The large library of already emulated building blocks, callback structures and declarative configurations can be used to speed up development significantly.It supports out of the box all the features of the MAME/MESS framework (various display rendering options, debugging, snap shots, user defined key mappings, pluggable ROMs, mass storage etc.).It runs on every platform supported by MAME/MESS (Windows, Linux, Mac OS etc.).

There are a number of advantages for using MAME/MESS for this emulator:

I just added some of the code for the 98780A and the 98770A displays required for 9845T and 9845C emulation plus supplements such as artwork and sound samples. In particular, Federico has done deep research on the (by far) hardest emulation challenge, the cartridge tape subsystem with the widely undocumented TACO chip and low-level cartridge tape format (chapeau!). He did not just write an emulator, but also used the MAME/MESS emulator framework for making it real.

Ulivi has done a fantastic job, and he did it double-well.
