Re: 80 columns on MZ700

I have look at my 80-column design and there are 2 options to cure the small dot problem caused by the faster modern chips. 1) increase the number of gates in the delay chain (the XOR gates have 2 times the delay as the invertors) we need 27nS so 3 spare XOR gates wired as buffers is 6 delays about ...

Re: CP/M on the MZ-80A

Hi , CP/M 2.2 or 2.3 for the MZ80-A is configured for a 40 column screen. If you have a MZ80-A fitted with the Kuma 80/40 column moderations there are 2 com files that switch the mode to the selected screen size allowing programs that require 80 column to run as intended. The Kuma 80/40 moderations ...

Re: 80 columns on MZ700

I design the SUC MZ700 80 column kit, and due to the interest shown on the forum I have look at it again, and found some possible solutions to the small dot problem caused by modern 74LS chips proagation delay is no longer 9nS. In fact the 700 did not require a frequence doubler as the CLOCK frequen...
