System Instruments 101A8

System Instruments 101A8 is a re-badged B5GS-R101-620. Most keys use amber switches. Space bar and enter use a white switch with a heavier spring. The date of the example below is uncertain. The controller chip appears to be dated 1987, while the support chips are from a year ending in 9, likely to be 1989. This is also consistent with the date range (1989-1991) cited by alps.tw.
