I'm using version 1.7

I'm using Version 1.8 of EightyOne with ZXPand version 1.12 "MOGGY"
and all works well for me.

My excuses to both of you.
Whenever referring to EightyOne Emulator, it would be much better to include the Version of EightyOne you have been using.
That makes it much easier to figure out wether the problem may be version/user related

Thanks a lot for your quick answer, I will check that. EDIT : AAaargh ! it's much more expensive ... As I do not know if I'll be able to use it in other cases than for the Spectrum ... I need to think about it ... The MongKok DSO168 is in a similar price range as yours, but its not availabe via ama...

This "Oscilloscope" is no use for Sinclair stuff because its limited to 200khz. Thats good for Audiosignals, but as the Sinclair oszillators are about 7 MHz the needed Oscilloscope will be twice of that (15MHz) at least. 20MHz analogue is ok for that. That is the usable frequency, not the sample rat...

Just for the curiosity, why does it has to be a solid core wire? Because multi Filament wires don't go into the holes of a Socket. And if you put solder on them they might already be too thick to fit into. And even more critical: These tinned wires tend to break off where the Solder stops making it...

It seems to work.

Just add a .txt at the end of the name
ROM1.BIN would be ROM1.BIN.TXT

You already got some hints in the linked thread
Are all PCB interconnects still reliable? Mine always break at opening the case

Please post a photo of your Rampack PCB. It makes it much easier to determine which PCB version it is.
Kind regards

flying wires are definitely possible, but its ugly and prone to defects. https://www.sinclairzxworld.com/viewtopic.php?t=189 Thats why I recommend PCBs. In fact I made a PCB myself that offers a plcc 27W512 with jumpers in a 24pin PCB as well as a programming adapter. The 27W512 is an EEprom, so no ...
