PROTOTYPE computer ISA card - RARE early model MRT - MS160SE like / 1.3 HISTORY

Description

I live in California and acquired this unique, truly one of a kind specimen that was preserved behind glass. Must be something along the lines of a first of its kind or PROTOTYPE computer ISA card - some thought a RARE early similar SSD MS160SE perhaps? I’m not leaning that way. I believe this to be your chance to own a piece of HISTORY. Condition is "Used", preserved and encased in the frame because this obviously marked an advancement in technology and you will not find another like it. Data crunching tech history, looking like ISA expansion card that used early memory module sticks in parallel in order to increase the polling data search and processing speed on the host MS 160 chip / processor to a level that was much faster than anything available. Perhaps the vintage precursor to modern SSD drives... could this be a moment in IBM historical lore ( its not Apple computer ). Likely temporarily held databases in RAM. I will ship USPS and insure the package. What you see pictured is 100% of what you will receive. Make up your mind as to what you would call this singularly unique item.  No refunds, no returns, no exchanges. My feedback will show I’m safe to buy from. Hope you enjoy owning a technological advancement and can appreciate the historical value.
