[Simh] C9.io

Fri Dec 1 17:54:19 EST 2017

I had the HP2100? Simulated on a Beaglebone Black for the Vintage Computer
Festival a few years ago. I had an TI Silent 700 teletype connected to it.
In a way it’s kind of a shame that a $35 (or $5 for a RPi Zero) is more
powerful than the mainframes of old. Actually I have a couple of the Pi
Zero W’s around somewhere. Computers used to be equipment to diagnose and
repair down to the component and electrical trace level.  Now it’s
literally throw away technology.

But even with an RPi running simh, it still needs to be on my home network,
which is one of the things I’d like to avoid for the “Production Server”
for lack of a better term.

As for not opening it up, I’m sure there’ll be someone who can figure out
how crash out of simh and keep/get a shell running, and now they’re sitting
on a machine inside my network with full access to my network.  And going
through setting up a separate vlan or even having it go through a second
router so it’s on it’s on it’s own network is more work than I’d rather do.
