[Simh] EXT :Re: C9.io

[Hittner, David T [US] (MS)]

You could also look at running a super-efficient 24x7 server at home to minimize your electric costs.

In my last computer build where I was trying to maximize performance with minimal power use, I put together an E3 Xeon Server with ECC memory that pulls an average of 35W running a SIMH VM with idle enabled.
It’s all based on buying power efficient equipment. It runs near noiseless and cool also.

Intel Xeon E3-1275v3 3.5GHz 4C with Integrated graphics (which is fine for a server). Max 84W.
32GB ECC memory (overkill for SIMH, but I do other things with the server  :-)
500GB M.2 NVME SSD
1TB 2.5” HDD
5.25” BLU-Ray ODD
80+ Gold PSU
Windows 10 Pro OS (for host)
VMware Workstation for virtualization, although you could use the built in Windows 10 Hyper-V virtualization for free

2.5” disk drives and SSDs pull a lot less power than their rotating 3.5” equivalents. So does using Integrated graphics vs. discrete video cards if the performance is OK.

Your point about having others manage the network security is pretty darn valid though !!

Dan, it is easy peasy, but not quite free, as if you want 24/7 access to the box, you have to keep the system running 24-7, so electricity costs. Plus, I’m planning on having others log in as well, thus I don’t want to open up my network like that. That’s why I’m looking for a free hosted/Cloud solution. That way someone else can deal with the rest of the network security. I do enough of that for work anyway, don’t want to have to monitor my home network as thoroughly.

Well, running from inside a house and making accessible from the outside is easy. But most ot my computers at home generally don’t run 24/7.

Mainly what’s needed for what we both want to be able to do isn’t really a shell account on a shared machine, but literally a dedicated VM instance, but we need to be able to access that instance through a public IP address.

On a home network, a private IP Address (192.168.x.x, 172.x.x.x ‘actually I don’t think it’s the whole 172 network’, or a 10.x.x.x) it’s easy enough to setup port forwarding to make it accessible. But on the Cloud based VM’s, I don’t know if there is a way to do it. Well, I know there ARE ways, usually involves paying for the instance, an external address, and possibly the amount of traffic.

Actually, I know Bluehost (is it still a thing?) used to  give you a VM with public address in combination with their hosting/domain name service.  But I’m hoping to find one that will not cost me anything.

Does anyone know if I can use the Cloud9 IDE to host a simh System emulation?

I know I’m able to build and execute it in the environment, but what I’d really like to achieve is to have a system (or several) running on various instances. And be able to connect to them from an external IP address, I believe I am able to SSH into an instance, or access it through the web based IDE.

An example might be better. Say I setup an HP system running Time-Share Basic. Would I be able to telnet to the TSB instance from various computers?

Thank you,

Joe
