-*This is not an official documentation. To get an official
-technical documentation of JSM-3 you need to contact Dakah
-representatives. * This is an unofficial review,
-that includes both detailed detailed guide on writing in JSM-3 machine
-code and a historical background on Fun Machine.
-
-This is the 15th issue of Scratchtip journal.
-
-*JSM-3* (or simply *Fun Machine*) is a computer manufactured by Dakah#sym.trademark
-corporation. It was first manufactured in a run of 100 items
-on $#[50]#sym.star.op#[233]$. It was designed for digital entertainment.
-Failed immediately, because nobody really needed a gaming
-computer with 32x32 resolution. Up to that point it is only remembered because
-it was the first publically available model from JSM series.
-
-== Review of external qualities
-
-Fun Machine a nefarious 32x32 led display on a 30x30 cm panel, wielded to the
-main body of the computer. It has 1 set of 16 levers on it and a
-power button with a led power indicator. Keyboard is not wielded to the main
-corpus. It is connected to it by a 1 meter cable. Keyboard contains
-50 same size keys. Keyboard is 40x25 cm in size. JSM-3 features 2^17 bytes (2^16
-words) of RAM and a JSM-3-Core CPU. JSM-3-Core is capable of running at
-80'000 tps. It should be noted, that operations that access high memory
-addresses can take seveal ticks to execute. The "bootstick reader" is located on the
-back of Fun Machine's frame. It is a long slide, that can read bootsticks t boot.
-Bootstick is a rom storage of a program that gets copied into the beginning of 
-JSM-3 memory during boot. Different models of bootsticks were available for JSM-3,
-with different models providing different rom capacity. The largest could store
-2^15 word long programs. There were also 2^11, 2^12 and 2^14 bootstick models,
-all compatible with Fun Machine.
-
-== JSM-3-Core
-
-CPU is directly connected to memory. CPU sends signals to
-monitor module, that in turn can switch on/off lamps on the monitor.
-CPU is capable of waiting for events on the input module, such as keyboard events or
-lever update event. Input module is capable of storing 20 events in a queue-like electrical
-scheme. Also, at any time CPU can read input signal from lever board. State of 16 levers
-is described by 1 word. 2^16 words (16 bits) of ram are available to CPU. JSM-3-Core in 
-JSM-3 is itself controlled by "boot-chip".
-After powering JSM-3-core, boot-chip temporarily takes control over memory card and starts
-copying boot program word by word into the ram, until bootstick reports the end.
-Physical interface of bootstick or bootstick reader won't be specified here.
-After boot-chip is done, it gives start signal to JSM-3-Corem which starts it's timer.
-Timer counts ticks, 80000 ticks per second. At the beginning of each tick CPU tries to
-execute one instruction and move to the next.
-JSM-3 lacks traditional caching. Instead, memory is divided into 3 level, based
-on it's proximity to CPU.
-- *M1*: Very fast. Addresses $[0, 2^8-1]$. Occupies first $2^8$ words.
-- *M2*: Fast. Addresses $[2^8, 2^11-1]$. Fast and very fast levels occupy first $2^11$ words.
-- *M3*: Slow. Addresses $[2^11, 2^14-1]$. Slow, fast and very fast levels occupy 
-  first $2^14$ words.
-- *M4*: Very slow. Addresses $[2^14, 2^161-]$.
