Not sure when the Sritek 16032 card was announced. It was discussed in the June 1983 issue of Byte Sudha Kavuru Modular Architecture, Designing a modular computer around the IBM PC https://archive.org/details/byte-magazine-1983-06-rescan/page/n195/mode/2up and shown at the January 1984 UniForum: "Sritek manufactures high-performance coprocessors and advanced operating systems for the IBM PC and XT. The Xenix System 3.0 for the Sritek 68000 coprocessor offers paged-memory management which can support up to 16 users. For the 16032 coprocessor we offer the Berkeley 4.1 BSD which supports 32-bit demand-paged virtual memory management and floating-point hardware. We will soon offer the 4.2 BSD version with networking facilities. UNIX System V will be available on the 68000, 16032 and 80286 coprocessors during the second quarter of 1984." https://archive.org/details/1984-proceedings-uni-forum-dc/page/n30/mode/2up For the 68000 card, an interesting writeup is in the April 1983 issue of InfoWorld. Sritek cards were offered to both MIT and CMU while they were waiting for the RT PCs. "CMU will use Sritek coprocessor boards Sritek, of Cleveland, Ohio, and Carnegie-Mellon University, located in Pittsburgh, Pennsylvania, have agreed that Sritek will supply the university with several hundred of its 68000 coprocessor boards with XENIX software for the IBM PC XT. According to a Carnegie-Mellon spokesman, the school will use the enhanced computer as a transition work station until its new system, under development in cooperation with IBM, is ready. The university and IBM are working on a 32-bit microcomputer with one megabyte of RAM and high-resolution bit-mapped graphics that will be used in a campus network of 7500 work stations. The machine is not expected to be ready until 1991, however. CMU also plans to offer the enhanced IBM XT to faculty, students and CMU employees for purchase at a discount. Sritek hardware will be included in this plan."
