This is my first post here! A few days ago I managed to get an Apple //e and I am very excited as I used to have one when I was a kid.
Luckily it comes with the Super Serial card but without 10-pin adaptor. So I made one myself. After recapping the power supply I have powered it up today and it works-ish (drives need TLC and my LCD monitor doesn't seem to like the composite output - or there is an issue on that. The green phosphor Apple monitor is still waiting for some caps which I found exploded!).
Anyways I have managed to run ADTPro on my Windows 10 PC. The issue is that the Apple doesn't seem to receive any data. I checked the RS232 connector and I thought I found a mistake but still nothing.
At some point I changed the "bootstrap" option from 9600 baud to 2400baud and with my surprise I could see some garbage scrolling on screen. But unfortunately I do not see anything if I switch back to 9600.
What could this be? To be honest I have no idea whether the serial card works but let's assume it does for now.
I have set the dip switches as recommended on the ADTPro website. The card is in slot number 3 for terminal mode and the header is pointing down for straight cable, which it should be.
I am using a USB adaptor which I use for other things and it's always proven quite reliable on old equipment. The signal LED flashes when the image is being sent - but the Apple does not receive.
For the short adaptor I used the attached pinout. I am using ADTPro 2.0.3
