My hardware design described earlier has been proven to be working:

DG403: two chips - no more components

Today two DG403s, four chip-capacitors 0.022 uF and 15-pin header were composed by me to the dual ternary multiplexer TRI41D:

1st test of TRI41D

TRI41D pins description:
1. S – select command (choose pins to connect)
2. N1 – connected to C1 if S=”N” (negative)
3. O1 – connected to C1 if S=”O” (ground)
4. … Continue Reading

Now I’m thinking about building binary circuits based on 74F00:

Explanation of idea about ternary hardware based on DG403 switches and also attempt to apply the same approach to 4-value logic:

DG403: one chip with resistors

Here I use undocumented feature of DG403 when normally closed switch opened by voltage lower than required to close another (normally opened) switch. Variable resistor is used to move that “both-opened” window to ternary “0″ zone (up from -3.0V…-0.8V to cover 0V).

DG403: two chips - no more components

Second scheme is more “correct” (nothing from undocumented features were used).

P.S. Ternary selector may be used as ternary inverter when RP=-5V, RO=0V, RN=+5V. … Continue Reading

Another portion – now about extension of 3niti alpha simu1 board:

Way to convert Morse code to balanced ternary code and back:

Again some handwritten ideas about implementation of microprogrammed hybrid of 8080/8085 and 6502/65C02 processors:

Today I created second test for my quasi-ternary board – it is a ternary clock:More about board is here

Today I did real test of this board with simple test program inside pic16f870 that reads “ternary” input (15 3-position slide switches) and sends it to “ternary” output (15 red-green LEDs):See details about this board here

After some evenings I had increased screen size of my Beige G3 from 800×600 to 1152×864 (65536 colors):Then I installed 2 cheap ($20 each) PCI-cards in it: first is 2xCOM-ports:and second is 1xLPT-port:Basically it is the same card with different assembling…. Continue Reading
