Comment: I don't this is notable enough for a stand-alone article you may be able to add some of this content to the Sol-20 article. McMatter (talk)/(contrib) 23:20, 4 March 2025 (UTC)
With this is my first attempt at writing an article for Wikipedia, please forgive this work's shortcomings; it's been a long time since I've had to support with references everything I write. With the VDM-1 board already posted on Wikipedia and the 3P+S also posted as a stub, it seemed fitting that this other board from the 'Subsystem B board set' should also have a presence. Due to the length of this content, maybe it only qualifies as a stub. Although the circuitry of this board was derived from the Sol, it is meant for use in the other computers of the era so posting it with the Sol-20 isn't really a good fit. Looking forward to hearing your suggestions as to how I can polish up this piece to meet the high standards of Wikipedia. Jason
CUTS Board
The Processor Technology Corporation (PTC) CUTS[1] (Computer Users Tape System) board provided cassette tape storage for the early S-100 microcomputers of the 1970s. This board could interface with one or two cassette decks to provided program and/or data storage.

Early kit computer enthusiasts with an S-100 bus system such as the MITS Altair 8800, IMSAI 8080 or similar computer chassis usually wanted to interface their computer to external devices such as a monitor, keyboard, dumb terminal, printer, teletype, paper tape reader/writer and cassette tape drives. The board first appeared in a PTC advertisement in the December 1976 issue of Byte Magazine. No details were provided other than the price[2].
Later, the board was incorporated into PTC's Subsystem "B" board set, which simplified system integration by eliminating the need for enthusiansts to source and combine the functions of various boards from different vendors. In the March 1977 edition of Byte magazine, the company started promoting the board set. The advertisement opening line read: "Subsystem "B" makes the computer you already have work almost as well as a new Sol-20."[3] Besides the CUTS board, the set included the VDM-1 video display board, the 3P+S Serial / Parallel I/O board, the GPM (General Purpose Memory Module) PROM / RAM board and one of three different RAM boards.
Combining an 8080 CPU board with the Subsystem "B" [4] board set along with PTC's CUTER firmware, either in PROM on the GPM board or loaded into RAM from paper or cassette tape, the computer was comparable in power and compatible with software written for PTC's Sol-20 all-in-one computer.
