- anybody know how well these upgrades fare with an aox micromaster?
- seems like it's more of an extensive upgrade than an aox micromaster,
- with the motherboard replacement. what can one do with the old
- motherboard? probably sell it i suppose.
-
- wonder if my existing hardware would continue to work with reply's
- turboprocessor system upgrade. i have a 50z with 10 mb ram (8 on
- an expansion slot), an 80287 math co-processor, an i/o card with
- 2 serial and 1 parallel, and a 120 mb hard drive.
-
- have a safe and wonderful holiday!
