Galaksija Character ROM
From Wikipedia, the free encyclopedia
Character ROM of home computer Galaksija is a 2716 EPROM chip that contains graphical definitions of Galaksija's character set. It had no special name and was labeled "2716" after the type of 2 KiB EPROM required.
[edit] Character set
Galaksija had a slightly modified (localized) ASCII character set:
- There were no lowercase characters
- Codes 91 to 94 represented Serbian language characters Č, Ć, Ž and Š, respectively. Letter "Đ" was not present in original version and was commonly replaced with "DJ".
- It contained 64 pseudo-graphics characters, having different combinations of dots in 2x3 matrix.
- Character codes 64 and 39 are used for two halves of the logo of Elektronika Inženjering company (they can be seen in "READY" prompt)
Each character was represented as 8x13 matrix of pixels. In this ROM, 8-pixel rows of each character are represented as 8 bits of one byte.
