content: As per title. I bought this scope a couple of years ago, and it's had minimal use. I'm able to borrow kit/bring things to work or college if I need to stick a probe on it that badly, and at present I don't do enough at home to justify its keep.I had to pull the backup batteries as they leaked (these are AA's mounted very far from any PCBs, though the terminals are now blue!). Other than that, it works, the tube is fine, internally damn near spotless although there is a dent and ding or two in the case.If there's any interest in the item I will get some pics up.The scope is on offer for free, I will pay postage, on a trade basis. I don't want money, I want bits and bobs.Things I am interested in:* Old CPUs, 6800/6502 family* Associated peripheral devices and memory, particularly lots of 8k x 8 parallel SRAMs* VDC's such as TMS9918 etc* Job lot/lucky bags of sufficient value/usefulnessWill also do a straight swap for a C64 or any Amiga model in working condition and internally unmolested (I don't give a shit if it's yellowed).If I've overstated the value of my instrument and am asking for the moon on a stick, I do apologise O0 Feel free to set me straight if that is the case.EDIT: As my post count is still quite low and I'm an unknown factor for trading on here, I'll add that once a trade has been agreed I will ship first in good faith

content: Hi,Just registered to reply to your post.Just getting started in electronics and been mulling buying an oscope but couldnt really justify it, however I do have an old C64 in the loft (used to do games programming back in the day) i would be happy to swap.Would need to check it works first, but let me know if you are interested. If so PM me and ill forward you my contact details.Cheers,Dean

content: Hi Dean, I'd prefer the instrument to go to a fellow newb in need if possible! So, if the C64 is in working order (including the power supply! I could build my own but it's a pain in the arse I don't want), I'd definitely consider a straight swap.I would require you to post a pic of the unit proving it's yours booting to the BASIC screen with no graphical glitches. As I said, I don't care about yellowing on the case, dust and spiderwebs not a problemAll it has to do is work as well as can be expected for something of that age.If you're starting from scratch I'll throw you the probes and an IEC power lead after all. Be warned: This scope is NOT in cal. It ought to show you a waveform but it'll not be suitable for accurate measurement. It is, however, a 4 channel 100MHz scope... it's almost as old as your C64 most likely!I'll do everything I can to make sure it will dish up a waveform and post pics for you to make your decision.

content: Id prefer it to be at least vaguely calibrated, that way ill have half a chance of knowing that what im looking at it is correct! Ill dig out the C64 and check to see if it still works, it hasnt been powered up in over 10 years.

content: Thanks for the info, HighVoltage. I am just about to get the thing powered up for some pics, so I will do that and take a photo of the result.UPDATE: Here we go...Front panel, powered up and not on fireAll four channels working. CH3/4 amplitude range is not the same as that available for CH1/2.After self-calibration process

content: Thanks for that. Managed to locate the c64 but not the PSU. I know its up there somewhere. Hopefully will get it powered up tomorrow afternoon. Ive got an old mono monitor so will take a photo of it powered up and post it.
