-
- >2. What fixes will I need for this, and also for 1.4 which is in my ST?
-
- You still need the folder fix program (FOLDRXXX.PRG, I think). The "best" fix
- is to replace the 1.2 TOS with 1.4, or even better, 2.06. Either will improve
- overall usefulness of your machine, improve disk read/writes, etc.

-
- All you really need is Atari's AHDI program and a good backup program such as
- Diamond Back II from Oregon Research. Use it.

-
- Slow. But don't put too much faith in arbitrary speed ratings.

-
- The MegaST does not include a VME port. Only the TT and MegaSTe have that.
-

-
- Old proverb... "You can never have enough RAM, CPU speed, or hard disk space."
- When you can afford it, just exchange the existing 20Mb drive mech with a
- bigger one.
-
- >7. Will a cache of some kind speed up the HD? (I am still not satisfied!)
- > If so, which programs are recommended?
-
- Unknown. If you want to speed up the machine overall, try a hardware accelerator
- from someone like Fast Technology or Gadgets by Small. Great STuff!
-
- >8. Is it possible to upgrade the mega to TOS 1.4? (how, cost, is it worth it?)
- >9. Anything else I should get or know?
-
- TOS 1.4 is a plug in replacement for your TOS 1.2. Cost should be about US$60.
- TOS 2.06 would require an adapter board from someone like Codehead Technologies.
- I believe their TEC (TOS Extension Card) retails for US$139 or so with TOS 2.06.
- You can also get an optional switch so you can switch between your old TOS 1.2
- and 2.06; great to maintain compatibility with older software.
