The newer SGS-Thomson part numbers are M48T02-200PC1 for the 200ns M48T02, M48T08-100PC1 for the 100ns M48T08. The Mouser inventory numbers as of 1995 are slighly different than the usual half numbers and are as follows: SGS-Thomson part Mouser stock number velocity capability M48T02-200PC1 511-M48T0220PC1 200ns 2kB M48T02-150PC1 511-M48T0215PC1 150ns 2kB M48T02-120PC1 511-M48T0212PC1 120ns 2kB M48T08-150PC1 511-M48T0815PC1 150ns 8kB M48T08-100PC1 511-M48T0810PC1 100ns 8kB M48T59Y-70PC1 511-M48T59Y70PC1 70ns 8kB As of Oct 1995, the costs for these chips from Mouser vary from US$16.00-23.12. Note that a quantity of people have reported issues utilizing the 150ns chips in SS2/IPX machines (however 200ns or 120ns works simply wonderful). My expertise is that these chips do not work correctly in the next machines: 3/80, SS2, IPX (they fail Post, however in any other case seem Ok). IPC. I do not know whether the Dallas chips work properly in the following: SLC, ELC. Dallas Semicondutor makes a clone of the SGS-Thomson M48T02 chips, the DS1642. Part quantity for the M48T02 is 73-712-06 (part name in catalogue: M48T02B-15/ST). Attaching a brand new battery onto an existing M48T02 My take on this procedure is that it isn't worth making an attempt to save the US$20 it would take to buy a new M48T02.
