YEAR: 1978
ITEM: Digital Computer
COMPANY: TEI Inc. (Special Systerms Group)
COUNTRY: USA
IN OUR COLLECTION: Yes
According to a TEI Special Systems Group brochure dated 1978, this MCS 112 is one of their "Mainframe" computers as opposed to their "Terminal Systems" (MTS xxx) or their "Processor Terminals" (PT xxx). The "112" indicates that this model has 12 card slots for various PC boards (each slot consists of a card guide and a 100 pin connector). The MCS 122 has 22 slots and is 7.5" deeper as a result. The brochure says the following about the MCS 112:
The serial number appears to be 013012. It is a beige color in the front and is missing the top/sides cover.
Sorry, no images have yet been entered. As we get more volunteers/interns we will be adding these images.
