BitScope BS31100 100MHz 1us/ fastest sweep Seems to be online brick N/A 2016-04-09 $40 De Anza flea market probe shot Unusually complete for flea market. Difficult GUI
Heathkit O-10 5Mc mostly. stiff knobs yes integral N/A spring 1976? $40 HS T.Rader's shop class needs knobs freed lost Z axis cover. Next bid was $25
Tektronix 323 4MHz mostly online no, weird cord no, missing 2016-04-09 $10 De Anza flea market workable Broken capacitor replaced. Ineffective horiz var bypassed.
Tektronix 434 24MHz dunno yet online integral N/A 2024-05-19 $78 West Valley flea market trigger level knob plastic missing
Tektronix 455 55MHz (I hear 50 or 60) RIP 2018-01-22, magic HV smoke escaped, but see below yes integral N/A 1987 $90? Foothill flea market 2023-07-31 resurrected w/parts unit from flea mkt A2 socket end broken. Realign and secure, check occasionally
Tektronix 455 55MHz (I hear 50 or 60) Parts unit. Would work OK if HV replaced. May still mine it for parts for mine. yes integral N/A 2023-06-11? $25? West Valley flea market Plastic case very fragile; taped up.
Tektronix 2235 100MHz yes yes IEC N/A 2018-03-10 $40 DeAnza flea market, have seller's card recovered could cover the 455. TV trigger
Tektronix 2236 100MHz a little flaky yes IEC N/A 2024-04-14 $20 West Valley flea market after a while, overheats and crowbars, no, that's probably flaky right-angle IEC.. Fan needs lubrication
Tektronix 2246 100MHz Seems OK. Some usability quirks. yes IEC N/A 2024-09-09 $20 West Valley flea market May need calibration.
Tektronix 2440, low SN 300MHz needs battery replaced online IEC N/A May 2015 $125 ebay daily driver Had POST errors. Bought for parts for other 2440, but fixed: Cabinet mounted wrong, bad airflow. Probes expensive.
Tektronix 2440, 2402A TekMate 300MHz Works, but TekMate doesn't (Lacks ROMs and CPU, I guess.). Came with boot floppy, though. online IEC N/A 2024-09-09 $20 West Valley flea mkt new daily driver Quicker and cheaper than replacing batteries in existing 2440.
