Good news from the #CZSpectrumPlus that I am trying to get back to life:

having replaced the proprietary #ZX8401 chip with a modern FPGA based replacement, the system now comes up again - wooohooo !! 🥳

I've also replaced the old keyboard membrane which had brittled to oblivion with a new one, however only a fraction of the keys are working. Maybe I need to replace the keyboard "big" ribbon cable connector as well (I already replaced the "small" one).

But things are going into the right dircetion ...

EDIT: I've replaced the "big" / "wide" keyboard connector with a new one and now all keys are working. More footage later, gotta go now to get cat food.

Why?

OFC since #Opera #Mini needs a trustworthy proxy backend any "#clone" would need an #OpenSource'd & #SelfHosting-capable #backend (similar to @ActionRetro 's #FrogFind .com as it breaks #E2EE.

Needless to say it would be a godsent for anyone stuck on #EDGEland and slower speeds (i.e. #SATCOM like #Iridium)...

Back to the #CZSpectrumPlus with the defunct #RAM - in preparation for the repalcement RAM that will arrive toorrow, I tried to de-solder the #IC marked in the photograph, but there were three pins that seemed to be nuke soldered to the #PCB and which I just couldn't free from solder in order to remove the chip. Especially pins 1 and 16 are very hard to come by.

Since I did not want to #heat #damage the PCB I stopped for the moment being to rethink my options. If you have any suggestions, let me know.

Meanwhile, I was able to cleanly remove what seems to be a makeshift fix for the keyboard connector. A fresh one, including a new keyboard membrane, is underway.
