   * You have an old VAX or Alpha with no special hardware, the system isn't under heavy load, and all you really need is a box to run some old application software or host a legacy database. The system just sits on a single IP and runs it's application from local disks. You'd probably be happy with **any** emulator in this case.    * You have an old VAX or Alpha with no special hardware, the system isn't under heavy load, and all you really need is a box to run some old application software or host a legacy database.

   * You have an old Sun box and it's presence in the data center is getting you dinged by security and other IT groups because of it's age. You know that running the hardware is cheaper than buying an emulator, but your problem is more than financial. You **must** get rid of that hardware so you stop being hassled by the clueless security people who (incorrectly) believe old systems cannot be secure or made secure. So you are willing to pay extra to have the hardware go away  while keeping the OS and applications it runs. Remember when it comes to Sun, your only valid option right now would be Charon-SSP and it's super-expensive. So, it has to be worth it!    * You have an old Sun box and it's presence in the data center is getting you dinged by security and other IT groups because of it's age.

 +  * You have VAX systems in your environment and need development and non-production emulated instances to help with writing software or day-to-day testing. By all means, go get SIMH and you'll be pleased. ​
 +  * You have an HP3000 PA-RISC box running MPE and HP's chaos has left you out to dry. You are worried that hardware might fail and you can't always get HP3000 parts anymore. They were rare systems to begin with. By all means get out your checkbook and be prepared to write a very large one for Charon-HPA. ​
 +  * You are a sysadmin who just wants some dev environments for his AIX systems. Put in the effort and get Qemu running. It's not that hard to get AIX 4 through AIX 7 working on Qemu nowadays. Sometimes it requires a mksysb image, but that's not too terrible. ​
