Surely this comes from when circuit boards were laid out on film by hand with black tape and pad stickers...? ###### From: "Bill Leary" Newsgroups: alt.folklore.computers References: Subject: Re: Tape Out, What's the origin Lines: 22 X-Priority: 3 X-MSMail-Priority: Normal X-Newsreader: Microsoft Outlook Express 6.00.2800.1158 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1165 Message-ID: <_NZ5b.267896$cF.83868@rwcrnsc53> NNTP-Posting-Host: 24.62.97.34 X-Complaints-To: abuse@comcast.net X-Trace: rwcrnsc53 1062758650 24.62.97.34 (Fri, 05 Sep 2003 10:44:10 GMT) NNTP-Posting-Date: Fri, 05 Sep 2003 10:44:10 GMT Organization: Comcast Online Date: Fri, 05 Sep 2003 10:44:10 GMT Path: chonsp.franklin.ch!pfaff2.ethz.ch!pfaff.ethz.ch!news-zh.switch.ch!switch.ch!news.imp.ch!news.imp.ch!snoopy.risq.qc.ca!chi1.webusenet.com!news.webusenet.com!cyclone1.gnilink.net!wn14feed!wn13feed!wn11feed!worldnet.att.net!204.127.198.204!attbi_feed4!attbi.com!rwcrnsc53.POSTED!not-for-mail Xref: chonsp.franklin.ch alt.folklore.computers:150363 "jpdavis" wrote in message news:vlg81ul52lur51@corp.supernews.com... > An FPGA/ASIC designer friend of mine and I were talking about the > common H/W engineering descriptive "tape out".

My recollection is that this is from when the PC boards were done with clear (or maybe it was white) plastic sheets and the traces, pads and so forth were done with black tape. Charrette used to sell the tape is all kinds of widths, down to some that looked almost like flat thread on a roll. Also used to sell round ones with holes in the center to do the pads for components. The "tape out" process was when you went from circuit diagrams on paper to working out the physical location of the components on the real-world circuit board and "taped out" the circuits. - Bill
