CCDOS2.13H以其丰富的打印功能,多彩的特显功能而备受用户的青睐。然而对于学校和家用电脑却无法使用CCDOS 2.13H汉字系统全部功能,因为它们大多只有单或双低密软驱而无硬盘,虽有同行解决了在双软驱上使用CCDOS 2.13H的问题,但对于24点阵汉字却无法使用,原因是一张容量为360KB的软盘装不下一个24点阵字库。 本人通过对CCDOS 2.13H的FILE0A.COM、FILE1A.COM、FILE24A.COM、PRTA.COM、ZF24.COM等几个文件进行反汇编分析后,找到了把CCDOS 2.13H系统修改成软盘系统的方法,让无硬盘的微机和只配九针打印机的用户也能享用CCDOS
CCDOS2.13H with its rich printing capabilities, colorful special significant features and much user’s favor. However, for schools and home computers, CCDOS 2.13H Chinese character system can not use all the features, because most of them only have single or double low density floppy drive without hard disk. Although their counterparts solved the problem of using CCDOS 2.13H on dual floppy drive, Dot matrix Chinese characters can not be used, because a floppy disk capacity of 360KB can not fit a 24 matrix font. After disassembling and analyzing several files of CCDOS 2.13H such as FILE0A.COM, FILE1A.COM, FILE24A.COM, PRTA.COM and ZF24.COM, I found a way to change the CCDOS 2.13H system into a floppy disk system, Let no hard disk computer and only with nine-pin printer users can enjoy CCDOS
