#tds700 — Public Fediverse posts

My #Tektronix #tds700 series scope got its #gotek floppy emulator and it works great. Its not exactly fast, but I expected this.

I did not need the "reversing" flat flex cable as the original one is the correct type.

This thing is approaching 30 years, but its not that dusty inside.

The fan sometimes makes some bearing noises (will add a few drops of oil to the bearings soon).

I am mainly concerned about the NVRAM and RTC. Both contain coin cells embedded in the package so I need to desolder them, make a big plastic dremeling mess and add new coin cells. But first I need to find out how to dump the factory calibration... this is a new rabbit hole - yay.

Apparently, it is possible to buy a pre-flashed Gotek to work with #Tektronik #TDS700 #TDS600 scopes. For 170€ incl. shipping.

Lets see if I can do this for ~40€.

Ingredients:
1. #Gotek SFRM72-DU26 (~33€ shipped)
2. #flashfloppy firmware to make it 1.44 MB
3. OLED display (2.5€ shipped) 128x32px
4. 26 pin 1 mm "type B" 200 mm flat flex (3.5€ shipped)

The flat flex is required to reverse the pinning.
The OLED is optional but cheap and a huge debugging aid.
Flashfloppy can be flashed with two USB-A to USB-C cables, an USB-C extension Adapter (A to A cable) and a piece of wire, so basically free (had the parts handy).

The flat flex will arrive at ~end of december. So maybe this will be an xmas gift to myself...
