So last night, I was literally sitting awake thinking of the projects I have set for Apple stuff this summer - and I remembered I had a Laser 128 EX/2.
From my understanding, these things are pretty much hen's teeth and there's little to no information about them on the internet. The Laser technical manuals I've found only go as far as the 128 EX, with no details on the EX/2. Unfortunately, this one did not come with a manual.
The one thing I do know about it, however, is that unlike the Laser 128 EX (which I have a couple of as well) - the EX/2 has a built in real-time clock. Lots of documentation online alleges that the EX does as well, but it indeed does not. I ran a GBBS Pro BBS off of my Laser 128 EX in the late 80's, and I had to fit it with an SMT No-Slot-Clock in the ROM door underneath the machine. The EX/2 also adds a built-in MIDI port. Otherwise, I believe it's the same as the EX - running at 1.0, 2.8 and 3.6 MHz selectable speeds - selectable by holding down "1" "2" or "3" during reset. The EX/2 also lets you set the system speed in the control panel (control-P-reset, or hold down P when powering on) as "Slow" "Medium" and "Fast".Many online resources also say the EX and EX/2 came with a built in 3.5.. I imagine some did, but all my EX's and EX/2's have 5.25's built in. Oddly though, I do remember specifically my original EX could format and read high-density disks. I plan on experimemnting with that later as well.
The EX/2, however, does indeed have a built in RTC. That got me to thinking.. Clock.. Battery.. Leakage.. Uh oh.
