98770A color display with hardware accelerated color graphics (45C). 98780A monochrome display with hardware accelerated graphics (45T).98750A monochrome display with standard graphics option (45B).Internal printer option (thermo printer).64 kByte up to 448 kByte LPU RAM and 32 kByte PPU RAM.Two 16-bit hybrid processors (LPU, PPU).Emulated Hardwareįederico's emulator simulates the following configuration: And please don't forget to report any bugs via the issue tracker on Github or the contact feature on this site. See the MAME project on Github and have fun with the emulator. The result is fully open source, and you are welcome to participate in the future development. 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.Īnyway, 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. #Mame library tool software#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.īut, 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.Īs 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.
