| Mac 512K, upgrading to Ke standard. |
Posted by: sigtau on 2018-04-05 14:24:43
I have an original 512K and I'd like to see if it's possible to get it up to 512Ke standards (800K floppies, etc).
Would I need to simply transplant Plus or Ke ROMs into the 512K, or is there more involved? Furthermore, is it even possible/practical?

Swap in Plus ROMs and an appropriate 800k drive. It's just that easy!

Excellent! Thank you for the insight. Whatever I end up sticking with I'll make sure the 64k ROMs remain safe as those seem to be the more valuable piece between the two.

The upgrade to Mac 512Ke in 1986 cost about $300 from Apple, which included dealer installation. You got the new 128K ROM, the 800K double-sided drive, a manual, and a Mac Plus System Tools disk. I believe the dealer kept your old 400K drive and 64K ROM set.

Off the top of my head the *one* detail I can think of that you might need to watch out for is the 800k drive might take a different cable than the 400k one. Presumably you'll be getting your 800k ROM and disk drive from a donor Plus, make sure you take the cable too.

The upgrade to Mac 512Ke in 1986 cost about $300 from Apple, which included dealer installation. And this is an excellent reason why non-"e" 512ks are so rare today. For anyone who was actually *using* their Macintosh verses giving up on it and stuffing it in the closet there really wasn't any good reason not to upgrade and plenty of good reasons *to* do it. There's only a tiny subset of software that doesn't run on a 512ke and I believe most of the incompatibilities involve oddball copy protection techniques that involved messing with the drive speed on the 400k drive, not ROM problems.
