I use a PC oscilloscope from UK company Pico Technology. An old model called ADC-200 which is no longer supported but meets my hobbyist needs well. It connects to a USB socket on my XP PC via a special adapter, the 'Pico USB Parallel Port'. Suddenly, it's stopped working. The Picoscope software tells me 'The ADC-200 is not connected. Looks like the adapter is broken. (Its LED is not on and it's not listed in Device Manager.) Probably somehow due to a PC crash in my shed/workshop when I triggered the house circuit breakers while fiddling with a Veroboard.
Pico don't sell the adapter any more (apparently one chip it needs is no longer being manufactured). After an entire day of research I have been unable to source a replacement.
Q1: Does anyone have one of these or know of any possible source please?
Q2: Another option is to upgrade to a PicoScope 2204 or 2205. Does anyone have either? I had a brief trial a couple of years ago but disliked it because it now has internal relays and these were frequently clicking on/off. I haven't seen any mention of this online, however, so I'm looking for others' views.
Q3: I changed the shed PC a few years ago. I've just realised that there is a parallel 25 pin port on it. That seems to mean I should be able to dispense with the adapter. But when I try to do so, I get that same 'not connected' message. Can anyone help on that aspect please?
