Following on from a previous 'quick hack' video (youtu.be/hhlw0inBhhI), I try to make an Atari ST(E) accelerator with one key extra ingredient: Fast 'Alt' RAM.
Great success or do I need to break out the comedy background music?
Many thanks to Exxos and the denizens of the Exxos forums (exxoshost.co.uk/forum/index.php), the EmuTOS team (https://emutos.sourceforge.io) and notably Christian Zietz from both for guidance on the conventions of AltRAM on the ST platform.

Old PLCC sockets tend to produce bad contacts after a while. Either simply through age, use or abuse (see my DIP STE adapter and PiStorm STE videos!)
The correct answer is to replace or retension the sockets as the sprung contacts have been pushed back over time.
However theres a much faster workaround for a short-term win.
Dont rely on this for your space probe, though...
