It's gotta be worth $20 by now. ?;-)
It's not as if no one is making SBCs anymore. ?The number of various
eval and development kits and learning kits is amazing.
I completely agree. I've got many - three 1802s (Elf2K, Embedded
Elf...), three 6502s (Replica-1, MicroKim...), at least one Z-80 (old
P112 kit), etc., and that doesn't count AVR-based products like clocks
and Arduino boards and Makerbot electronics.
They are all interesting and pretty much each one is cheaper than the
kits from the 1970s in the 1970s, but so far, few come in under $50,
and none come in at $10-$20, unlike an "obsolete" computer at the
bottom of its curve.
So I fail to see the intrinsic value of an old one
with limited
capabilities.
For me, in some cases, nostalgia (the ones I saw advertised but
couldn't afford as a kid, like the Super Elf or the Elf-II), in other
cases the aesthetics of 1970s layout and design (hand-taped, curved
traces). I can run PDP-8 software via emulation (simh), on a 40-pin
microprocessor (IM6120 in my SBC6120) or on "real iron", but I'm still
fascinated to do so on a TTL-era (-8/i or -8/L) or transistorized (-8
or -8/S) machine.
Or am I not thinking as a collector would?
Dunno about that, but I picked up the Starter Kit because it was
interesting (the most striking feature at first inspection was the
pair of S-100 slots at the top of the board) not because I expected it
to increase in collector value. I've done more research (reading the
docs) than experimentation (pushing buttons), but I've still learned
something and it's still been entertaining.
