As I said, this time the design notes were extensive since I wanted this emulator to be specifically designed for embedded systems, so only 48k emulation, optional framebuffer rendering, very little additional memory used (no big lookup tables for ULA/Z80 access contention), ROM not copied in the RAM to avoid using additional 16k of memory, but just referenced during the initialization (so we have just a copy in the executable), and so forth.。快连下载安装对此有专业解读
Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.
