' Installation and Operating Instructions   C For your entertainment, we offer the OpenVMS VAX DECtape driver. If > you're interested and have a Unibus VAX, find yourself a TC-11> controller and TU56 driver and plug them in. There is no setup@ involved; CSR address and interrupt vector are hard-wired in theF TC-11. The driver has been tested on OpenVMS V5 and runs as best as weD can tell. It has never been run on V6, but it should not be affectedB by any of the V6 changes. It is rumored that the driver would alsoD work on a Q-bus VAX, connected via an Able Qnivertor board. However,7 to the best of our knowledge this has never been tried.   E This kit includes driver executables built for OpenVMS VAX V5 and V6, C named DTDRIVER_V5.EXE and DTDRIVER_V6.EXE, respectively. To install G simply copy the appropriate driver to SYS$LOADABLE_IMAGES:DTDRIVER.EXE. ? If you want, you can rebuild the driver from source by invoking D BUILD.COM. To load the driver (once you've plugged in the hardware),E simply invoke SYSGEN and tell it to AUTOCONFIGURE ALL. The DECtape is G in the autoconfigure tables! You will have to edit the driver, however, B to set the number of units that it configures, because there is noG reliable way for the driver to interrogate the controller for available F units. Look for the DEFUNITS declaration under the DPTAB macro and setG the number of units you want to support. The driver supports 4 units as  shipped.  C The driver supports all the standard disk I/O functions, so you can C INIT and MOUNT file-structured DECtapes. Or better yet, get hold of F VAX-11 RSX and a copy of the old FLX, and you can read your old DOS-11F DECtapes. Unfortunately it does not support formatting, so you'll need? a supply of preformatted tapes. Also, there's no 18 bit mode so > there's no way to read all those old TOPS-10 tapes. Maybe in a future version...   D The kit also includes a random DECtape exercisor called TCRANDOM. ToF run it, just invoke or submit TCRANDOM.COM. For a real show, submit asF many TCRANDOM jobs as you have drives and watch the overlap seek logic work! 
