It just sits there, mocking me...

It mocks me; and I am mocked. 

Decades I've had that Minimus-7 speaker in my possession... so many moves, and over a decade I've been looking for a mate to it, figuring that when Ifni deigned for it to be so, one would manifest in a thrift or flea market at a price I couldn't refuse.

Until a couple months ago... when I gave up and sent it to med in a "care package". Flash forward to now... and what should mystically appear on my thrift RADAR...?

Yup. Even better condition, and CAD$3.99...

Okay, okay... Ifni has spoken. I shall have one Minimus-7 speaker; no more, no less.

I'm sure I had some of them when I was a teenager. Either that or they were extremely similar. They replaced the car door speakers and bit of wires I had before. They were plugged into this piece of shit

[Martin.M]

the different from a museum to a well cared collection is:

The most old instruments in a museum are clean,
inside dirty , and of coarse not working.
This is a problem.

I have saved a wonderful old computersystem, and changed there for a lot of money elkos to make it running again.
Now, the Maya have started allready, but the WAF (womens acceptance factor) for a multiprozessor Unix mashine is smaller then zero, so I asked some museum if the are interested.
But not one of them want to give me the pay for the spares I have used to make it running. It is complete, icluding document, licences for the OS and the May and so on, and not a penny, this is our time.
I will find a way to put the little ONYX2 also in this work room, to play with the amazing grafix ("reality engine"). Not museum.

Yeah; EVERYBODY did. They were Radio Shank's "Small Wonder" speaker for decades; well-known to have amazing volume & clarity for size due to the solid cast aluminum enclosure. Still often used as monitor speakers for amateur radio benches & portable mixer stations. And perennially abused as you describe; tucked under the front seats of people's winter-beater because they couldn't be arsed to actually install speakers in the doors.

Time to feed the chiddlers... I wonder who I should feed them to...?

I'm stuck in a similar conundrum with one of these:       A Heath-Zenith Z-120 (only with working 5MB Winchester drive) that has been in my possession for 15 years. I had it working 100% about 10 years ago; however the usual "dried-out caps" failure mode has claimed it as another victim, and I just couldn't make it to the top of my repair que in all that time due to assache factor and cost of parts...

I've seen oodles of articles where a collector or small museum space has spent the time & money to buy and restore one of these seminal works of computer history... but every time I try, I simply cannot find ANY ONE OF THEM willing to even pay the cost of shipping. So yet again, it goes into storage to be dealt with on another day...

very nice and a good WAF that 
SGI Oldies eat 30A from the plug, they are not so easy to handle in the appartement 
I have some experience with heavy instruments, we will find a solution

So Martin, was it a distortion adjustment that fixed the sine wave?

I need to find a RES, 470, 5%, 10W, VERTICAL MOUNT Keithely Part Number R-401-470.
Made by KRL/BANTRY code R-LF3476.

I already wrote an email, let's see.

That guy was stupid.

I'm not going to argue with the universe; even a old fat dwagon like me, that's definitely fighting outside my weight class.

Hey @med I found another meter you could stack on your ugly duckling Fluke. Even painting it blue wouldn't help    eBay auction: #401819975598

There's a sibling here. At the moment ~ 20 € plus shipping (unsure if seller wants to ship outside Sweden, I can proxy if med needs to use more paint...)

Good to see you again, old friend.

I may have located an example of the Data Precision waveform analyzer that goes with my Data Precision polynomial function generator. If you have the waveform analyzer, the function generator can play back digitized waveform captures as output. We shall see if it works out.

I have no use for it. Looks like it's only 3.5 digits and no Ohms function. I've moved beyond that. 

[AVGresponding]

@mnem, mojito, obviously...

Oh, and also, I've been using a pair of Minimus 7s I bought new from Radio Shack  Tandy (this is the UK after all) for the last 30+ years, they're bloody great!

Good evening TEA fellows,

I'm back from vacation and I saw you guys had lots of fun.  Didn't expect something else. 

Today I've found a nice Nixie frequency counter from General Radio for around CHF 60.- (ca. EUR 50.-)
Will pick it up next week.
This is how it looks like:


Cheers,

Mounty

Karma is balanced somewhere. UPS were good to me today. They phoned me up first thing apologising that they were going to be late for parcel collection. Then turned up on time! 

It's not the first time UPS are total suckers to me:
Last year there was a nearly similar situation with only one difference: I waited for nothing and the UPS driver delivered it to a UPS service point instead of me stating he wasn't able to deliver it to me because I was not there -but I was..

Strange karma.

Just in time...



should I do something on that exposed copper? Epoxy?

[bd139]

I usually just stick kapton over it. If the substrate is damaged then it gets epoxy.

F§%& you moron!
