(Tek part number 670-8622) was introduced, in which the character generator is based on digital values stored in a 2732 EPROM instead of Gilbert's analog ROMs. This board was installed e.g. in the [[R7103]] and [[7904A]] and still used some of the Tek-made readout ICs like the timing generator. The design is similar to the readout mechanism in the [[2465]] series. | (Tek part number 670-8622) was introduced, in which the character generator is based on digital values stored in a 2732 EPROM instead of Gilbert's analog ROMs. This board was installed e.g. in the [[R7103]] and [[7904A]] and still used some of the Tek-made readout ICs like the timing generator.
