Most have at least one broken rear tab. Some are
missing the floppy cutout
cover, or the cover is there but won't stay in place. No cracked tops
though.
I think these were designed for low cost and aren't as robust as other HP
systems of similar vintage.
For me it seems as sturdy as anything HP (older) I have. BUT it is made
of plastic, and plastic breaks...Old plastic breaks easier... :o)
I do love my 712 :D So bad mine isn't the 100MHz model, but I can live
with that :D
Now, If I could learn to use the inverse assembler... :oP
