Re: looking for an old IBM knob from a 609 calculator panel

I think that is an IBM specific knob. I will keep an eye out for one, but do not hold your breath! It is certainly not a common knob. Is it for a 1/4 inch shaft? -- Will On Mon, May 27, 2019 at 11:41 PM Bob Rosenbloom via cctalk wrote: > > A long shot I know, but I'm looking for an IBM knob

Re: looking for an old IBM knob from a 609 calculator panel

Those knobs look like they are cast pop metal or zinc or something, not Bakelite. -- Will On Tue, May 28, 2019 at 1:27 PM Electronics Plus via cctalk wrote: > > Looks like a standard old Bakelite type knob to me. I pulled a lot from old > equipment 30 years ago. I will check to see if any got

Re: Kids these days...

Oh, it is a legit company - the SEC filings could not faked on the government website. I went down a quick rabbit hole, and I saw things about the HQ being in Kiev, 1000 to 1 stock splits, and so forth. No one would ever invest in that company unless they specifically wanted weird things to

Re: Kids these days...

It is a real company, but if you look into the SEC papers, there is a LOT of shady stuff there. Its sole job may be to move money in and out of the Ukraine. -- Will On Mon, Jun 10, 2019 at 12:01 PM geneb via cctalk wrote: > > On Mon, 10 Jun 2019, William Donzelli wrote: > > > Wow, you fell

Re: Pleas ID this IBM system....

The logo is sort of wrong for the era. I think it is just a sticker that was applied. And I do not think Puma would have been running on just a model 20, and especially in such an "interesting" datacenter. By the 60s, they were already a good sized company. -- Will On Tue, May 21, 2019 at 6:26
