CMOS problem
ZXNet echo conference «code.zx»
From Evgeny Malygin → To ALL 11 November 1998
Hi, ALL!
I read the article "CMOS clock" and decided to assemble one for myself, but
Gluck diagram provided by Roman Milukov (see diagram below)
but there is no program for installing them (preferably if this program is
display the time on the screen, i.e. read time values from h
Asikov), but I can’t write it myself. If you can, please help me -
hundred, and send me the program or, if you know, which BBS ee
you can get the name and address of this BBS. Thank you in advance for
any help.
P.S. The program can also be run under IS-DOS
