Good day and thank you for stopping by to take a look at this item from the store
Today's posting is for 4, 1MB 30-pin SIMMs featuring Texas Instruments TMS4C1024DJ memory chips.
**These are matched set**
These specific units are built with 9-chip "True Parity" architecture, which was the high-standard for professional computing in the early 1990s.
These were pulled from a working system over a year ago. As such I did not have the means to retest them. They have been kept in ESD bags since being pulled. There are no known issues with these items. Please see shipping and guarantee section below for former info on returns/refunds/guarantees.
