<p>Covers the basics</p> <p><b>New page</b></p><div>The '''TC08 DECtape Controller''' is a [[DECtape]] [[device controller]] for early [[PDP-8 family|PDP-8s]] such as the [[PDP-8/I]] and [[PDP-8/L]]. There are two variants; the TC08 is for machines which use the 'positive I/O bus'; a variant model, the '''TC08N''', is for PDP8's with a 'negative I/O bus'. It is a [[Direct Memory Access|DMA]] interface, using [[three cycle data break]]; it generates [[interrupt]]s when operations are completed. It is implemented as two custom [[DEC card form factor|dual]] [[backplane]]s holding [[FLIP CHIP]]s. It is intended for use with either the [[TU55 DECtape Transport]] or the [[TU56 DECtape Transport]].<br /> <br /> ==See also==<br /> <br /> * [[DEC indicator panel]]s<br /> <br /> ==External links==<br /> <br /> * [http://www.bitsavers.org/pdf/dec/dectape/tc08/DEC-08-H3DA-D_TC08_Jun70.pdf PDP-8 TC08 DECtape Controller Maintenance Manual] (DEC-08-H3DA-D)<br /> * [http://www.bitsavers.org/pdf/dec/dectape/tc08/TC08_Engineering_Drawings_Dec76.pdf TC08 Engineering Drawings]<br /> <br /> [[Category: PDP-8 Storage Controllers]]</div>
