I often spend more for items I am interested in then our more frugal list-mates would think rational. An informed consumer making a decision should be happy about it. If, on the other hand, the buyer believed that this was an "original" Mark-8 (of 1974 vintage) then he will be disappointed, not happy, when he realizes his error. If, on the third hand (for those born near a radiation source), the buyer was led to believe that this was an original, then he was defrauded. There is a strong parallel between this discussion and another hobby of mine; old Corvettes. In Corvette circles, however, there are guiding organizations that carefully research, document, classify and adjudicate what is original and what is not for a given car. You can, therefore, be sure that if you are buying a car judged by the National Corvette Restorers Society as "Top-Flight" then you are getting a car that is 94% original or better. Original in their case is defined as "that's the way it came from the factory." Points are deducted for aftermarket parts and modifications and undue damage to original parts. The vintage computer hobby is probably a long way from that type of situation, but many of the same "rules" apply and certainly the same issues arise from time to time. At least amongst those that collect for historical value over hacking value. Erik S. Klein www.vintage-computer.com

The PM9052 was a module used in the Pro-Log Series 90 Programmers. It was the personality module for 2716 and 2758 devices. The Series 90's were interesting because they used the Intel MCS-4 series of processors. The PROM(s) on each module contained the subroutines to implement the programming algorithms unique to each device. Most likely the code in your 1702's is 4004/4040 code. Bill Kotaska
