Interface standards are of prime concern, particularly internal bus standards. The S100 bus dominates the personal computer market, but it has serious drawbacks and other buses are being considered.</p><p>Instrumentation buses for microcomputers present problems of cost and manufacturer support. CAMAC is a well supported system, but in its parallel form is probably too expensive for most microcomputers. The IEE-488-75 bus is already available and is well supported.</p><p>Communications interfaces on microcomputers owe everything to minicomputer and mainframe systems. The ubiquitous RS-232-C has been improved in the specifications RS-422/3. Better definition for internal and instrumentation buses are in preparation and offer the hope of easier system design.</p></div>","PeriodicalId":100928,"journal":{"name":"Microprocessors","volume":"2 6","pages":"Pages 329-332"},"PeriodicalIF":0.0,"publicationDate":"1978-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0308-5953(78)90204-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76739292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
