Ok I got another ch341a with the same pcb as in this thread. I can get it to connect however I am trying to read a 93S56 it reads everything as FF. Reading 93S56 as a M93C56 it reads but entire memory is blank FF any ideas? Note this is being done in circuit no modification to new programmer on 2 jumpers.

93x and 95x are different type. One is spi, the other one is i2c

93x can also be read with CH341x as 24x i2c chip but you need to connect pins differently to ch341. Look at datasheets for 24xx and 93xx pinout and you will understand how to connect.
I remember 1 and 8 are the same, other are differently connected and one pin is connected hi or low depending if you have 8 or 16 bit chip. I don't have access to my pc at this time, but you can goolge for it, im sure you will find solution fast.
