1+ for low resolution (up to 1024x768), because it is hard to create more than one tube in one case, because of limited throughput and charges interaction.
Essentially, electron beams push off each other, so it is really hard, to create more than 3-4 electron beams in one case.<p>Really, each beam is cloud of charged particles, and if two such clouds intersect, they will scatter, and will cause image distortion.<p>So must feed all image through 3-4 beams. And even with so low number, it is not easy and have imperfections.<p>More read next.<p>2. no. tft lcd, essentially, is large dram chip (each Thin Film Transistor have some memory effect, and in few tft designs, display cells are just memory cells, so cpu could access them via memory-like interface, or via system bus).
In lcd, neighbor cells are so disconnected, that real hi-res displays work as 3-4 or even more logical displays in one physical, and this solves throughput problem (some monitors just used 3-4+ physical connectors).<p>3. no. This is limited by throughput and charges interaction.<p>4. unfortunately, no. Analog computers defeated by digital, because it is really hard and expensive, to make analog precision better than ~1/10000, but digital could stack few bytes, and even on old 8080 easy achieve 24bit (10^-6), or 32bit (10^-9) or even 64bit (10^-18).<p>5. partially agree. Small transistors more prone to single events, but large more prone for accumulated dose, because appear radiation matter move effects.<p>So real rad-hardened computers have few alu-s and circuit, which could disconnect non-working alu and connect spare.<p>ps it may sound non-politely, but really good read on magnetic tapes is Donald Knuth, and fortunately, their mathematics is very similar for hdd-s.
