March 23rd, 2018:

	As announced on Mastodon, I received my 40Mb RAM card for my 
Powerbook Duo 280c yesterday.  I had it installed within minutes of 
opening the package!

I couldn't find my Torx 8 bits to unscrew the Duo, but it didn't matter... 
its previous owner stripped all four screws when he robbed the 'book of 
its original RAM card.  Thankfully, I had a hex driver that *just* fit, 
and was easily able to take the Duo apart.

I was amazed at how much quicker the Duo performed.  It booted up quicker, 
folders and applications opened faster, and I was actually able to *USE* 
the programs that were installed on the 'book.  It must have been owned by 
(or assigned to) a corporate or professional user, as it had the CRM 
program ACT! installed with a large contact database.  Also included were 
MS Office, Quicken, QuarkExpress, and Claris Organizer 2v2 (my favourite).

The Duo is a tricky beast.  It has no removable media built-in: No floppy 
drive, no SCSI port, no CDROM drive, no ethernet, and is too old to have 
had USB.  This makes getting things into and out of the Powerbook a 
challenge.  It has a built in serial/printer port that can be used to 
connect to another Mac via LocalTalk, but that's only useful if you have 
another Mac. It also has a built-in 14.4k modem, but that's only useful if 
you have terminal or internet software (and a dial-up account).

Of course, I have all of these, but I want to use the Duo as a standalone 
machine, so I bought an Apple MiniDock.  This gives the Duo external 
video, an ADB port (keyboard, mouse, joystick, graphics tablet), serial 
and printer ports, SCSI port, and a port for an external floppy drive.  In 
other words, comparable to a typical Apple desktop model of the time, such 
as an LC475 or 575.

Thus, it's just a matter of loading up a SCSI ZIP or JAZ drive and copying 
things over to my Lombard or Powerbook 1400.

Now, what to do with it?

I've been on a privacy kick lately, so I will probably end up using it as 
a daily planner and "sync" it with my paper planner and HipsterPDA, 
keeping my stuff off Google etc.  The Duo is around the same size as my 
DayTimer planner, but somehow thinner and lighter!
