Surface-mounts are already done.
Oh well... A good reason for me not to order one, then.
Yeah I was thinking the same thing. :-( I'd love to have a P112.
Actaully, I was hoping for soem semi=mindless fun stuffing PCBs. Of
course the other ereason is that if I solder it myself I can use lead/tin
solder, and avoid problems with joints that fall apart after a year, or
grow tin whiskers.
I am getting ratehr fed up wit hthe number of 'kits' that are sold that
are not really kits at all. IMHO an electronic kit should come as a PCB
and a bag of components. Nothing should be pre-soldered. If you need
special soldering equipment (such as an oven for BGA devices), then this
should be mentioned in the kit description, but it should still be up to
the constructor to do it. Or at least offer 2 types of kit -- totally
unsoldered / with the BGAs pre-mountes (There's something of a precedent
for this in model enginenrign. Some of the steam locomotivew kit
manufactueres offer either sets of raw castings for you to machine on
your own lathe, or kits of finished parts which just need assembly with
hand tools)
I thought it was most 'unfair' when Heathkit started selling 'kits' with
pre-assembled PCBs. I think if I'd bought one of those I'd have returned
it as 'does not meet the description' Heck, I feel that floppy drives
should have come in kit form -- you get to stuff the PCbs, assemble the
mechancials nad do the alignemt. I guess hard drives would have to come
as a pre-build HDA, but you still should have got to stuff the PCBs.
