Anyone score any good retro hardware recently? I'm in the market for an Amiga a1200, but eBay's getting too rich for my blood. Hoping to run into some C= hardware at my local thrift stores -- we have one in Berkeley called "Urban Ore" that has a pretty big computer section... Fingers crossed!

Just today I got a KP1801BM1 from the Russian Federation. It's a
16-bit CPU
of Soviet design that also happens to be binary-compatible with the
DEC
PDP-11. Other than that, I don't know very much about it at all, but
it
should be fun to try and make it do something, either with an Arduino
Mega or
a small FPGA.
Whoah, that sounds pretty cool -- that's like early 1980m yeah? I find Soviet-era technology pretty intersting, especially some of the out-there industrial design... Congrats :)

I lucked out and was able to get a TRS-80 Model I with working
monitor.

Oh, that's nice. How much memory on that badboy?

While this isn't retro COMPUTING, I collect some Russian antiques. Lighters, a couple neat watches, some WWII era bomb fuzes (I have a
large fuze collection... very cool.) and a few phones - I love seeing
how DIFFERENT their tech was that ours, and most of it is built really well. Very industrial, as you say, too.

What you think about my PET find? Should I pop? I don't particularly
LIKE PETs; and don't need 3(!*) but... good deals are harder to find
these days. I might pop.
I am *thinking* of grabbing three PET machines - a seller in PDX has
finally went down to the $900 that I was asking... two are working,
and one just stopped - so should be something the community can help
get rocking again.
I also want an a1200 - but as I was telling you the other day, I think
my next purchase (if I can find the dang hardware!!) is a MiSTeR...
for ME, an fpga is 'close enough' and way better than software
emulation... while it ain't cheap, I think it will be my next 'retro machine'.

Was even thinking about picking up some C64 perifs, maybe disk drive, as aL> you can hook those right up to the FPGA as well...

Today, with significant help from a Russian Facebook friend, I was able to get ahold of the technical documentation for the BP1801BM1 (pinouts,
timing diagrams, etc.), in Russian, of course. It's a very interesting
chip, and now I want three more! It turns out that two of the pins are
used to encode the "CPU number" of the processor, 0-3, and they have
built-in circuitry to arbitrate access to the system bus based in this number.

First, YES - Jeffs KP1801BM1 sounds rad... I'm a little green to use
an Arduino to make retro chips do things, but... I'm interested in
hearing what beeps and boops he makes it do!!

I'm a fan of soviet-era 35mm cameras. As you'd mentioned, their tech
is different, simple, foolproof, and genius in many ways.
I shot hundreds of rolls of film through a LOMO LC-A, a little compact camera that, like many Soviet era cameras, was a copy of a Japanese
camera that itself was a copy of another.
They put an amazing little triplet lens on it, and in keeping with the "simple yet genius" description, had an amazing shutter. A spring
opened the shutter, and a solar cell charged a capacitor. When the capacitor charged, it powered an electromagnet which closed the
shutter. That meant you could do 2 minute exposures without draining
the battery. In order to adjust for different film
speeds/sensitivities, a rotating disk with different sized holes was fitted over the solar cell. Slower speed film meant a smaller hole,
and a longer exposure.
Other cameras were blatant copies of other cameras - Zorki cameras,
for example, were made in a Contax factory that was taken over in WWII
and moved to the Soviet Union.
