I just want to know if you proceed with the upgrade and, in this case, if you succeed.
I am asking about this because I am trying to collect data about which 32K chip have people found to be usefull. I have found three different codes, each one with a different brand label, and in two cases, the donator was a non-working HP48G. Anyway, in two cases, I removed the chip from a deffective sound board. There were two chips in that board and I have already used them.
I have these RAM ID codes/numbers written somewhere, I just have to find the file. Have you taken note of yours, if any?
Another issue: as I see, the HP17BII has the same board and layout, but the HP42 uses a main chip with another package. The question is: would the HP17BII accept a 32KRAM chip as well? Not that I intend doing this, I just would like to know if its O.S. will address the extra 24KRAM. If the answer is Yes, then the HP17BII+ will need no further HW enhancement, only SW additions (if any) and a Kinpo-like design.
