- Stan,
-
- What's so bad about an 8088 PC with dual floppy drives and no hard disk?
- Depending on what you want to do with it, how well it performs, and how
- much you paid for it there may be nothing wrong with it. The same thing
- applies to a 3084. Does the 3084 with VM/XA do everything you want
- it to do? Do you need any features that a 3090 or ES/9000 offer and
- are not supported on a 3084? Do you need any features of VM/ESA?
- Are response times and batch processing queues acceptable? How much
- is the Q costing you (make sure you include the costs of maintenance
- and subtract residual value from the cost of a new box).
-
- It's really very simple. Does it do what you want it to do, when you
- want it to do it at a reasonable cost. If it does than there's
- nothing wrong with running a Q. Lots of people still are.
-
- Personally, I'm a big fan of keeping old hardware running as long as it
- is cost effective. Too many people feel that they need to be on the
- latest (or at least fairly current) technology and then never
- exploit it. If you're not going to exploit the new technology you
- might as well use old technology and pocket the savings.
-
- On a personal note, up until last fall I was running an 8086 at home
- with just a 20 meg hard disk. Pretty whimpy system for a systems
- programmer but it did everything I wanted it to do. When I eventually
- had requirements that the poor old 8086 couldn't meet I went out and
- bought a 486DX-33 with 16 megs of memory and a 200 meg hard disk.
- I didn't go to a 486 until I needed it; the 8086 was just fine for my
- previous requirements. I hope to keep pushing the 486 until long after
- the 486 is considered a whimpy system.
