- I've run TP 5.5 [IDE] on 8088 and 8086 machines in the past, and
- didn't notice anything was missing or non-functional that was supposed to
- be (You wouldn't expect XMS usage on an original Tandy 1000, even if
- it is maxed to 640K with a Zuckerboard). Some recent database applications
- utilizing TurboPower's toolkits cause one of the older platforms to choke,
- but that's because it hits the RAM ceiling at 256K. And there are no plans
- to rewrite the app with overlays so it can run on the museum piece.
-
- Most older XTs I've seen come with CGA, so any app rewritten for this
- class PC employing graphics should probably recognize our old buddy CGA.
- Care has to be exercised if porting a database program, let's say, to a
- hard-diskless box. Those darn floppies are so darn restricting when it
- comes to data storage!
