Probably because of the Plus ROMs on board.By the way when it boots up 7.1 ATM says that its a Macintosh Plus.
Your 512k has a SCSI upgrade?yes the scsi internal zip drive 100 works great in the 512k /w plus rom's
If it does, it must have a RAM upgrade also, because the 512k generally can't run System 7.x (presumably because there's not enough RAM).By the way when it boots up 7.1 ATM says that its a Macintosh Plus.
They seem to run quite cool, although I don't know how they are in terms of power consumption. They certainly use more power than modern 2.5" laptop drives, but old drives tend to use more than newer drives so they might turn out to be similar.Its too bad these 2.5" drives won't fit in a Powerbook due to complete lack of room. Not to mention the potential heat problems!
Gods, I hope not. The trackball was a superior pointing device until... well, when did the magic trackpad come out? Wasn't until the glass trackpad from Apple did they finally become useable, in my opinion.Trackpad upgrade?
Oof. That'd be a tight fit, even if you made your own adapter. Looking at the profile view of the HDD, you might be able to make one that sits on top of the HDD if you use the same type of ribbon cable and flat connector.I'd need an SCA drive, but looking at that, I'm pretty sure it intrudes into the space taken up by the trackball.... at least in the Powerbook 100 series. That and I'm pretty sure they don't make SCA to 2.5" 40pin SCSI adapters.
