Don't Nurse Old Hardware - Emulate It
gManZboy writes "Bob Supnik, former team lead for DEC's VAX microprossesor, has an article up on Queue about his Computer History Simulation Project and how emulating old servers may be a better way to keep them running that servicing the physical machines. So how many PDP-11's can you run on a Pentium 4 anyhow?"
pentium IV's can you emulate on a PowerPC?
emulating old servers may be a better way to keep them running that servicing the physical machines.
I disagree. It's not the same thing.

5.25 ????
Damm are you young, when someone says 5.25 disks I dont even think too old.
Bring on the 8 Inchers, now those were the days they also fly great, late Friday afternoon we would all let loose by flying them around like frisbees, all fun and games till someone get a corner in the eye.

Regression testing. Emulation's nice, but it ain't the same as the original hardware. Which means, people will need to regression test. Trick is, the people that know what that old PDP-ll is actually doing retired a long time ago. So who's going to write the test cases?
Been wanting to buy an old 11/780 shell for a while. Not for a bar, but to mount both my Mac and Gaming PC innards in. This'd be a real trip to run as an emulator during parties. Now to interface the VT-120... Hack the shell I suppose. Run everything USB. >:D

Problem is... The WOW factor on these servers has gone from WOW look what it can do. To WOW your still using that.

I think they patented some aspects of emulation, mainly to shut down people selling GBA emus for palmtops.
Given the current state of patent law, chances are that any universal Turing machine now owes Nintendo royalties.

How are you going to emulate a 5.25 inch drive to read old disks?
Easy, it's an emulator. It will just multiply your 3.5" drive by 1.5.
But what about lesser known mainframes such as the Prime.
How sad for me to find out that not only am I obsolete, I'm also obscure. I remember PrimeOS fondly if for no other reason than it was where I cut my teeth as a young hacker.
Would have been about 1984, dialing in to a univeristy's Prime in another state. Me on my Commodore 64 with my Microbits 300 baud modem (I was the fastest kid on the block. Everyone else had 110 or baudots). It was like NetHack, but in real life. Learned to get in. Learned to navigate. Learned about these great things called directories (unavailable on my Commodore 1541 disks). When I couldn't affort to buy new floppy disks, I started storing all of my programs and files on their mainframe. They seemed to have plenty of space. I was in there for more than a year before I got caught. Ah... those were the days.
Thank for you for the trip down memory lane.
