VIC-20
From C64-Wiki
The VIC 20 is the forerunner of the C64, but in some states it appeares under the label VC-20 in Germany and the label VIC-1001 in Japan. The VIC-20 was produced from 1981 until 1985.

[edit] Introduction
It was the first homecomputer of Commodore which had the ability for a colored screen and it was the first computer which exceeded the mark of one million computers sold. 1982 it was the most sold Homecomputer and was awarded through a board of international computer magazines as the "Computer of the Year" in the homecomputer category. On its release it had cost just under 299$ (1.000 DM) and it is a friendly computer by the price, by the dimensions an by the usage; still without any previous knowledge.
Despite of his small memory there have been several programs, especially games on cassette and cartridge, published. In addition there have been a lot of programs in form of a listing for typewriting in computer magazines in the 80s of the 20th century.
Its original name depends on the new developed and used video chip the VIC (Video Interface Chip). In Germany the name comes from Volkscomputer and that means peoples computer. Until its production ended, there had been more than 3 million VIC-20 systems sold.
[edit] Construction
The appearance looks like the C64. The VIC-20 is a keyboard computer and has the following ports and interfaces (i - input / o - output for datas):
[edit] Backside
- Expansion port (44-pins; i/o) to connect cartridges
- Audio-/Video (5-pins; o) to connect a monitor VIC-1510/1701/02/1804 or with an GF-Modulator a television
- Serial Bus (IEEE-488, 6-pins, i/o) to connect a diskdrive VIC-1540/41/70/71/81 or a printer MPS 801/802/803, VIC-1515/1525/1526
- Cassette-/Datasette-Connector (Cassette port 12-pins; i/o) to connect a cassette recorder (Datasette) VIC-1530 or CN2
- Userport (RS-232 or Centroncis; 24-pins; i/o) to connect cartridges, resetbuttons or modems (incompatible with the Userport of the C64/C128!).
[edit] Right Side
- One gameport (Controlports, 9-pins, i) to connect a joystick, lightpen, mouse or a few paddles
- Power Switch
- Power Connector (Power; first variant 2-pins; new variant 7-pins round) to connect the power supply (first variant 2-pins; new variant 4-pins round)
[edit] Mainboard
The internal assembling is different to the C64:
- Processor: MOS 6502B with ~ 1 MHz

- Serial printer like the matrix printer CR-variant VIC-1515 or VIC-1525/26.
[edit] VC-20 Cartridges
- 3 KB Memory extension cartridge VC-1210, which rises the capacity up to 8 KByte; what means it could be used 6655 chars (Bytes).

[edit] Variants
Beside the japanese version, there have been a swedish version with special characters and a french version for SECAM TVs.
Furthermore there have been different versions of the VIC-20/VC-20 logo in the upper left corner of the case.
[edit] Using
As like by the C64, first you must connect all cables, insert the cartridges and turn on the peripherals, before you should turn on the VC-20.
Than you can see the following start screen with the blinking cursor (if the cartridge has programms on it, they will start immediately):
**** CBM BASIC V2 **** 3583 BYTES FREE READY.
The blinking cursor shows the computer user, that the BASIC interpreter ready is for input. Now it can be entered, loaded or saved BASIC programs. The CBM BASIC and the Using of BASIC commands is exactly with the Commodore Basic V2 of the C64. The following meanderings are:
- A small BASIC memory of 3583 bytes (chars) free.
- It has got a logical screen line of 87 chars (4 lines with 22 chars).
- The maximal BASIC linenumber is 63999.
- The dimension of arrays with the BASIC command DIM is only partly possible, using of 3 or 4 dimensions is required a memory expansion.
- The constant PI (π) is only 3.14159265 (a digit lower as at the C64)
- The memory adresses, which is using by the BASIC commands PEEK and POKE, are different.
- Screen memory from 7680 until 8185 with the chars code from 0 until 127 (128-255 repeat the chars 0-127)
- Color-RAM forum 38400 until 38905 with the following colors:
- 0 Black
- 1 White
- 2 Red
- 3 Cyan
- 4 Violet
- 5 Green
- 6 Blue
- 7 Yellow
- The screen color (frame and background) can be changed with the memory adress 36879 with the values from 0 until 255. First will be set the frame color (first 8 colors: black, white, red, cyan, violett, green, blue, yellow), after that the background color (16 colors: black, white, red, cyan, violett, green, blue, yellow, orange, lightorange, rosa, lightcyan, light violet, lightgreen, lightblue, lightyellow). Meaningful values are from 8 until 15, 24 until 31 or from 248 until 255, because the frame color has got only 8 colors (by using interim value the text will be unreadable !).
- Sound: The memory adresses from 36874 until 36877 with the values from 128 until 255 for the registers 1-4 (4. register is only for noise generation) and memory adress 36878 with the values from 0 until 15 for the volume.
- Tip: By using memory expansions (particularly the 3KByte RAM-Cartridge) can be changed the memory adresses !
