- You mention that the emulator combines "the SimH project structure" with Wild Hare's commercial code.  I take this to mean that the emulator is an extension of simh to support the listed DG processors and devices.  Can you clarify which version (and ideally commit id) of simh is this based on?

- I noticed that the license document available on the dgbeta <http://www.novasareforever.org/dgbeta/> page only covers the legacy software produced by DG.  Given the inclusion of commercial code in the simh executables, can you clarify what license the emulator binaries are released under? (Ideally this would be published along side the legacy license text).

- Do you envision at some point publishing the simh emulator changes as a pull request to the simh project (presumably under the simh license)?

Again, thank you for your efforts here.  It's great to see this software opened up to hobbyist use. --Jay On 11/10/2022 5:47 PM, Bruce Ray via cctalk wrote: > > Wild Hare Computer Systems is pleased to announce the public beta > release of its Data General Nova and Eclipse emulator. > > This emulator allows the full range of DG 16-bit Nova and Eclipse > computer software to run on Microsoft Windows and Linux platforms, and > will become a major part of Wild Hare's increased efforts to preserve > Data General's significant contributions to computer history. > > The emulator combines portions of Wild Hare's commercial products with > the SimH project structure to create a single emulator for the 16-bit > Nova and Eclipse computers.  The program supports a wide range of > features, including: > > Processors: > >     unmapped Nova, SuperNova, Nova 1200, Nova 800, Nova 2, Nova 3, Nova 4 >     mapped Nova 840 >     mapped Nova 3/D >     mapped Nova 4/X >     Eclipse S/130 >     Eclipse S/140 >     Eclipse S/150 >     Eclipse S/120 >     Eclipse Desktop Generation Model 20 and Model 30 > > > Peripherals: > >     TTI/TTO        primary console (TeleType) input/output >     RTC        real-time clock >     TTI1/TTO1    secondary console (TeleType) input/output >     PTR        paper tape reader >     PTP        paper tape punch >     PLT        plotter >     LPT        line printer >     MTA        mag tape unit >     DSK        fixed-head disks >     DKP        moving head disks >     DEP        Desktop Generation disks >     DZP        popular "Zebra" moving head disks >     QTY        4060 "Quad" asynchronous multiplexers >     ALM        4255 Asynchronous Line Multiplexers > > > Software: > >     Operating Systems > >     DOS        Novas (first DOS written for Nova) >     URDOS        RDOS for Novas and Eclipses (in unmapped mode) >     MRDOS        RDOS for Mapped Nova 840 >     NRDOS        RDOS for Mapped Nova 3/D and Nova 4/X >     ZRDOS        RDOS for Mapped Eclipses >     MP/OS        Nova 4 >     DG/RDOS        Eclipses >     AOS        Eclipses >     MP/AOS        Eclipses > >     Languages > >     ASM (Assembler) >     MAC (Macro Assembler) >     ALGOL >     DG/L >     FORTRAN 4 >     FORTRAN 5 >     FORTRAN 77 >     Extended BASIC >     Business BASIC >     MP Pascal >     SP Pascal >     COBOL >     Interactive COBOL (ICOBOL) >     PL/1 >     RPG II >     IDEA >     INFOS II >     CEO > > Prior Data General knowledge is beneficial to using the emulator and > corresponding DG software.  For convenience, Wild Hare has created > container files of pre-configured operating system environments and > their corresponding languages to minimize the time needed to enjoy the > full DG "experience". > > This "beta-level" software release is intended to gather user feedback > to help guide future product development.  Bug reports, comments, > suggestions, ridicule and giggles can be sent to > beta(a)WildHareComputers.com. > > Further information is contained in the emulator beta release web page: > > www.NovasAreForever.org/dgbeta > > > > Bruce Ray > Wild Hare Computer Systems, Inc. > Denver, Colorado USA > bkr(a)WildHareComputers.com > > ...preserving the Data General legacy: www.NovasAreForever.org
