Summary

The Tangerine Microtan 65 main board. The gray ribbon-cable at bottom left is for the Hex w:keypad/w:ASCII keyboard. Above it is the silver-coloured UHF modulator for the television display, set to the UK UHF Channel 36, with the metal-cased 750 w:kHz system-clock crystal immediately to its right. Farther right, the long, thin IC is the 6502 Microprocessor - in this case, a Rockwell-produced one - and the smaller chip below it with the green spot on it is a 2716 w:EPROM containing the TANBUG V2.3 monitor program. Below and to the right of the TANBUG socket are three links (cut in this case) for modifying the address decoding allowing use of the TANEX expansion board. The gray connecter at the far right is for connecting the board to either the system's mini-motherboard, which featured two slots for the use of the TANEX expansion board, or the full-size system motherboard with further additional slots allowing greater expansion. The board itself contains 1 w:kilobyte of w:RAM in the shape of two (1024 X 4 w:bit) 2114 chips.
