    "description": "The Turbo serie was launched simultaneously with the <a href=\"computer.asp?c=313\">X1 serie</a>.\nThe X1 Turbo has enhanced graphic features. It also has additional hardware compared to the X1 serie: DMAC, CTC and SIO as standard. CTC &amp; SIO can be however implemented on X1 serie through additional FM sound board or Mouse/Rs-232C board. But DMAC can not.\nTurbo series has a special \"KANJI\" V-RAM, compared to X1 series which has only one way to display \"KANJI\" symbols, a heavy task for the Z80A: to display 1 \"KANJI\" character, 96 bytes of data are transfered to the V-RAM. As opposed, Turbo series just send 3 bytes of data (2 bytes for shift JIS code, and another 1 byte for attribute) to the \"KANJI\" V-RAM. Among the 8-bit systems, only the X1 Turbo serie and MZ-2500 have this special V-RAM. The access time is almost null, compared to the X1's V-RAM which is slower.\nIn the same way, it takes from 2 to 8 seconds to define P.C.G (user generated characters, similar to sprites) with the X1 serie, while it takes only 0.5 seconds with the Turbo serie. The <a href=\"computer.asp?c=416\">MZ-2500</a> is also equiped with this feature.\nThere were in fact three models:\n- Model 10: built-in tape recorder, no KANJI ROM, only 48 KB V-RAM (additional 48 KB available as an option),\n- Model 20: one 5.25\" disk drive instead of the tape recorder,\n- Model 30: two 5.25\" disk drives",
