In addition to supporting new memory allocation strategies as controlled by INT 21h/58h subfunctions 0 and 1 (get and set allocation strategy, respectively), DOS 5.0 also added new subfunctions 2 and 3. These allow the caller to query (subfunction 2) or set (subfunction 3) the UMB link.

“The abundance of goods and services will be very, very large. Prices will be very, very low,” he continued. “So I would suspect by 2040, $30,000 will buy—and maybe $10,000 will buy—much more than you can buy if you have $100,000 income today. So the level of income you need in a deflationary economy will be very different.”，这一点在51吃瓜中也有详细论述
Once the basic stuff was working, I wanted to load TAP files directly, simulating cassette loading. This was the first time the agent missed a few things, specifically about the timing the Spectrum loading routines expected, and here we are in the territory where LLMs start to perform less efficiently: they can’t easily run the SDL emulator and see the border changing as data is received and so forth. I asked Claude Code to do a refactoring so that zx_tick() could be called directly and was not part of zx_frame(), and to make zx_frame() a trivial wrapper. This way it was much simpler to sync EAR with what it expected, without callbacks or the wrong abstractions that it had implemented. After such change, a few minutes later the emulator could load a TAP file emulating the cassette without problems.
