content: G'day Everyone,Note: This scope is not in a fully functioning state and is more a "project" or "for parts" type deal, but should make a good platform to repair from.This thing has had a hard life. I acquired it sometime in 2016 I believe. It must have been dropped or crushed. Some panel beating was required to push the back corner out. When I first saw it, I expected the neck on the tube to be broken for sure.  2/4 feet are missing. There is no front cover, manual or probes.I haven't had the time to continue the repairs on it and figure it's better in someone else's hands.The unit fails diagnostics  but does show waveforms. It has issues with POST showing the following errors:Fail ++ Acq/Proc InterfaceFail ++ AcquisitionFail ++ Attn/Acq InterfaceThere are some unusual vertical ~7v offsets. The 0.5v test signal sits at ~6-7v. If you line up the trigger line with a rising edge on a trace on the screen, it will trigger. Just any of the voltages you read are not meaningful/accurate.The front panel is in "OK" shape. In 2019 I re-capped it.  There was a lot of corrosion. Also an issue with one of the large ICs In 2021 I reworked U508 which had been completely detached from the board by corrosion.

I’m looking for $200AUD. The unit must be collected. I don’t want to ship it.SC and EA Mags - Free the proviso would be that they are collected, and you take all of them. I don’t want to ship these or split them.EA 1981: mayEA 1986: CompleteEA 1987: CompleteEA 1988: jan, feb, mar, may, jun, jul, aug, sep, oct, decEA 1989: CompleteEA 1990: CompleteEA 1991: CompleteEA 1992: CompleteEA 1993: jan, feb, mar, apr, jun, jul, aug, sep, oct, nov, decEA 1994: jan, feb, mar, apr, may, jun, jul, aug, sep, nov, decEA 1995: CompleteEA 1996: feb, mar, apr, junEA 1997: jan, feb, marSC 1988: may, jun, jul, aug, sep, oct, nov, decSC 1989: feb, mar, apr, may, jun, jul, aug, sep, oct, nov, decSC 1990: CompleteSC 1991: feb, apr, may, jun, jul, aug, sep, oct, nov, decSC 1992: jan, feb, apr, may, jun, jul, aug, sep, oct, nov, decSC 1994: aug, oct, nov, decSC 1995: jan, feb, mar, apr, may, jun, julSC 1997: jan, feb, junSC 2001: jan, feb, mar, apr, may, jun, aug, sepSC 2002: decSC 2005: jun, jul, aug, sep, oct, nov, decSC 2006: CompleteSC 2007: jan, feb, mar, apr, may, jul, aug, sep, oct, novSC 2008: jan, mar, apr, may, jun, aug, sep, oct, nov, decSC 2009: feb, mar, apr, jun, jul, aug, sep, oct, nov, decSC 2010: CompleteSC 2011: CompleteSC 2012: feb, apr, jun, decSC 2013: feb, marPlease let me know if you have any questions via DM or reply here.Cheers,Tim.
