I have the BCD decoder schematics done. There are two implementations. A one
IC and two connectors.
The other is a bunch of diodes transistors and resistors. I do not think you
would like to fool with this as long it can all be done by a 40c IC. I just
put it there for reference so you will see how complex it is.
Fig. ! is the IC implementation. Fig.2 Is the discrete implementation at
high level. Fig.3 shoes how
to build a NAND gate while Fig.4 shows how to build the inverter.
It will take 2 to 4 days to put it on the web. If you are in a hurry, send
me your FAX number and I'll fax it to you.
If you have any questions, please write.
Have fun
Alex
