The Tektronix 4041 is a small, BASIC-programmable computer designed as a GPIB instrument controller. It was introduced in 1982.
Standard built-in components included a 20-character alphanumeric (14-segment) LED display, numeric keypad, a 20 character-per-row, 60 mm-wide thermal printer, a DC-100 cartridge tape drive, and a real-time clock. Interfaces included one or two GPIB and RS-232 interfaces, and an optional SCSI bus to connect diskette and hard drives. RAM could be ordered between 64k and 512k Bytes. The CPU in the 4041 is a Motorola 68000.
The base model was equipped only to execute pre-tokenized BASIC programs stored on cassette or in ROM. To develop programs, a 4041 with option 30 was needed. Option 31 added a full alphanumeric keyboard although the catalog recommended a CRT terminal for editing programs.
Option 01 added second GPIB and RS-232 ports, while option 03 added the SCSI interface and an RS-232 port.
The 4041 has a stand-alone enclosure but matches the height of TM5000 enclosures. Mounting kits allowed installation of a 4041 plus a TM5003 or a 4041 plus a 4041DDU disk unit side-by-side in a 19" rack.
The front panel contains a socket to connect the keyboard. It uses the same 4-pin LEMO S-series connector as used for the power supply connections of many Tek probes.
