Drives Andy Bakkers is making this special software package available through Micro C Complete source HEX amp documentation files on an 8 SS SD disk Also outlines on disk the hardware changes needed 29 95 More Goodies ROMs from Micro Cornucopia There are two ROMs in each Kaypro a monitor ROM and a character ROM The Monitor ROM supplies information for the Z80 processor on such things as how to get information from the disk drives and which character to use as a cursor The character ROM works entirely in the video circuit and it determines what the characters look like on the screen for instance does the f have a high small cross bar or a lower longer one of the Micro C character ROM When you speed up your Kaypro you are speeding up the processor clock so you have to use a monitor ROM that will also run at the higher speed You are not changing the video clock when you speed up the Kaypro so you don t need to change the character ROM unless you want the nicer looking character set Since the monitor ROM tells the processor how to do disk accesses you are going to have to change that ROM in order to upgrade to larger drives Pro Monitor II for Kaypro II 1 This ROM is a fast part so you can run 4 or 5 MHz with your Kaypro II 2 It gives you a non blinking block cursor much less irritating though you can specify a standard blinking underline if you prefer it 3 It does faster disk accesses even if y
