content: Hello peopledebug-interface.zip(14.37 kB - downloaded 486 times.)Some people tell, link and topic with info about 20 pole "gold finger" of CPU board is broken /dead.I have developed one board and use him for repair of Tektronix DSO.I put my design for free usage in community. Look attachments with zip-files.Design has a little fail. (connector 180° turned , pleas put it to board, as compoment side of interface show to bottom. )Compoment list is self explained. ;-)1k= 1k ohm 0805C (no marking) = 100nf 080518p = 18pf 0805 capacitor of XTAL. foregone of 18pf capacitor for XTAL is possible, but i don't recommed.232 = MAX232 SOIC 1668681 = MC68681 UART controller PLCC44, obsolent ->alternative: XR68C681,https://eu.mouser.com/ProductDetail/MaxLinear/XR68C681CJ-F?qs=H%252BP%2FcHWii3cJWiitYFrC3g%3D%3D3.686 Mhz XtAL (Case probably 406 , example:https://eu.mouser.com/ProductDetail/ECS/ECS-36-18-7SX-TR?qs=PzGy0jfpSMuQfY3oexCZOQ%3D%3D)dsub 9 female 90° connector.connector is 20 pole edge 2.54mm pitch connector for cable.

content: Hello Madao,I like this idea and design but would it be possible to change the controller + connector so the output would be USB compatible (Wndows, MacOS, Linux) ?In my humble opinion, if using J40 connector of TDS500-700 serie then let's modernize and go USB... otherwise there will be problem or specific cases like this console port re-using the option 13 controller, seehttps://www.eevblog.com/forum/testgear/console-port-debug-adapter-for-tek-tds500-tds600-and-tds700-series-scopes/msg3420060/#msg3420060Nowadays most computers do not have RS232 so you need another adapter to transform signals, at the end it cost too much money and trouble.Albert

content: I have removed my answers, because, it isn't written good.I say, i stay on RS232 and RS232 & USB Adapter. It is not expensiv. And i didn't feel like for developing for new version with UART-USB onboard. I didn't like, if i am annoying in five years later, because new driver (from update) disable old UART IC. (See Profilic with old UART IC and FTDI and fake.-IC -> asshole !)

content: Dear Madao,Thank-you for your generosity.By a small miracle, I was able to obtain the original Motorola DUARTI had some PCBs fabricated using your GERBERsI am offering a kit including your PCBA and critical components, I hope you don't mind.If you want to post (or PM) your Eagle Files, I will try to make a USB version using CH340C.Please save the Eagle files in a version compatible with Eagle 7Kind regards,ICEZEBRA

content: It is okay :-)It is for free using, if it is not modified (except correction of edge connector (180° flip ))This was my design fail and i didn't feel like change it. -> this is why, i soldered LED on "bottom"This was my last sprint layout project. Now, i am doing with kiCad.

content: Quote from: madao on December 02, 2021, 02:17:38 pmHI, mattI have a question. I saw IC MAX232 and three LEDs indicators on the circuit board, which is obviously different from the components used in the circuit diagram. I just want to use the serial port to transmit data and need to have LED indication function, that's all.Profun

content: Quote from: madao on October 23, 2021, 06:35:54 pmVery well. Can Sprint export to IGES or DXF or Eagle?Do you have a KiCad version? Can that be exported to Eagle?Again, thank-you. The console works very well.That was clever of you to add the loop-back solder jumperAs you can see from my photos, I took advantage of it.

content: Regarding the crystal capacitors. The crystal in the kit is a true crystal, not the footprinted oscillator.Therefore the crystal capacitors are unbalanced.The capacitors come pre-soldered in the kit as shown.LEDs are not included in the kit.
