At the end of my previous DSTB1 video, I soft loaded EmuTOS to enable the ability to use the AltRAM that DSTB1 provides as TOS 1.2 (installed in ROM) does not support AltRAM. This left me with only 70kB useable STRAM free!
Time to do something about that.
DSTB1 is an open-source accelerator and AltRAM card for the Atari ST: github.com/dh219/DSTB
Dual TOS kit: exxoshost.co.uk/atari/store2/#0245
Reset switch: exxoshost.co.uk/atari/store2/#0114

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...
