Visiting a surplus shop today, I found a small herd of Tek Oscilliscopes. Some of them looked pretty old to me. They want real money for them too. Details: Model Mod 1 Mod 2 Cart ----- ----- ----- ----- 564 3C66 2B67 564 3A74 2B67 Y 504 Y 561A 3A72 2B67 5111 5A20N 5B10N 515A Y 549 1a1 Y D11 5A14N 5B10N Y 504 564B 3A9 3B4 Prices were originally $200 for most of them, except the 549, which was $400. Some of them had been marked down to $100. They have some kind of automatic decrease in price based on how long things stay in the store (1% per day?), but most of them have been there only since late February. And I don't know how that effects the ones that were "manually" marked down. I suspect these prices are outlandish. The same place wants $25 for 2400 baud modems. :-) Anyway, the age-based discount may eventually make the prices more reasonable. At least for the scopes, if not the modems. The ones marked "Y" under "Cart" had a "Scope-Mobile" cart with them. But I didn't think to get model numbers from those. Oh, and I can't guarantee that these work. I didn't ask if they would allow me to test them, and at present I don't know enough to be able to test them anyway. I also can't guarantee that they'll still be there when I next visit. Questions: 0. How old are these guys? 1. Are any of these potentially useful for computer work? Can they handle the frequencies used in old machines, say, up to a few MHz? (Judging from their apparent age, I wouldn't hope for much more than that.) 2. Anybody want one? Be aware that in addition to the price tag, I wouldn't expect these guys to be easy or cheap to ship. (At least one time in the past I have had to back out of a deal because I couldn't arrange shipping within cost & safety constraints.) And the carts are probably too big to go through UPS or USPS. Given all that, if you want one, let me know. Cheers, Bill.
