[Simh] SIMH VAX on a Kindle

[Mark Pizzolato]

Not that I know of, but I’d try:

    sim> ATT XQ NAT:TCP=2023:10.0.2.10:23

and then on your host(kindle) do:

                $ telnet localhost 2023
Or
                $ telnet your-host-ip 2023

Clearly you’d need to be running a telnet daemon on the OS inside the simulator…

Doesn't seem to work:

NAT args:
NAT network setup:
        gateway       =10.0.2.2/24(255.255.255.0)<http://10.0.2.2/24(255.255.255.0)>
        DNS           =10.0.2.3
        dhcp_start    =10.0.2.15
  Protocol[State]    FD  Source Address  Port   Dest. Address  Port RecvQ SendQ

It can't talk to my internal network or the outside world.  What's the next step?  Is there a way to force NAT to use a specific interface on the host?

I'm surprised that the NAT(SLiRP) connectivity isn't useful here.



Meanwhile, a while back it was no problem to build the current codebase with the ADK.  I haven't tried in a few years, but there it s no reason it shouldn't still work.

I used to use the SIMH for the Android (which cost me about $13) but now that I have Lollipop.  It doesn't work anymore.  I know I could hack my tablet but it's connected through a Cell service provider so I'd rather not.  I know the terminal I used Better Terminal Emulator Pro which was required for the port.

I ended up with a spare Kindle Touch and didn't need an ebook reader, so I decided it might make a nice platform for SIMH.  After jailbreaking and rooting the Kindle, it's just Linux (and X11 for the Kindle interface) so cross-compiling SIMH was easy.  Networking over wifi obviously doesn't work (as recently discussed here) but networking over USB does, so it's tethered to a server for connection sharing.  The performance is pretty good for such a small device.  It's about equivalent to a real VAX 4000/200, so approximately 5 VUP.  Certainly more than fast enough for 4.2BSD on a simulated 11/780!  Next step is to get some sort of console working - right now there's no way that I have found to display console output on the screen.

Oh, somebody made SIMH a paid app?  That's no fun... In theory it should be easy enough to cross-compile binaries using the Android NDK.  I'll look into it at some point when I have a little bit of time.  Of course networking isn't going to work over wireless, but I suppose there's still plenty to do without it.
