It can also successfully download (but not run) a TU58 emulator bootstrap from PDP11GUI over the Console cable.<\/p>\n<p>However, it is currently unable to:<\/p>\n<ul>\n<li>Download an RX02 image to an 8&#8243; drive attached to the DQ419 using PDP11GUI; or<\/li>\n<li>Run the TU58 bootstrap once it has been downloaded<\/li>\n<\/ul>\n<p>When the TU58 bootstrap is run, the SLU Channel 0 TXD line gets held permanently in the SPACE (+VOLTAGE) condition (ie RS232 Break signal) because the bootstrap progams halts early in its execution.  It halts as soon as the instruction &#8220;call xmtcmh8&#8221; is executed (it halts at 002142, which is unrelated to the address space used by the bootstrap program).<\/p>\n<p>This problem is suspected to be caused by a fault on the 11\/03 processor board (M7270), althrough it could possibly be caused by an unserviced Trap condition triggered by some other event.  Note we did temporarily install the W3 link on the M7270 board to prevent LTC interrupts.  This however did not fix the problem, and the W3 link was eventually removed again.<\/p>\n<p>Console and TU58 emulator cables (both DB9F-to-DB9F), to connect to a PC via USB-to-RS232 dongles, have been fabriacted and are working fine.  They have been left inside the MINC.  The back panel has 4 x DB9M plugs on it.  The top position (marked Console) is for the console. The next position down (marked &#8220;SLU2&#8243;) is temporarily being used for SLU0 (the TU58 Emulator) as the wiring to the other 2 DB9Ms is faulty.<\/p>\n<p>The serial ports on the MINC are configured as follows:<\/p>\n<p>CH0: 38400, N, 8, 1 [TU58 emulator]<br \/>\nCH1: 300,   N, 8, 2<br \/>\nCH2: 9600,  N, 8, 2<br \/>\nCH3: 9600,  N, 8, 1 [Console]<\/p>\n<p>The BDV11 is most likely currently configured to boot the MINC software off an RX02-format 8&#8221; diskette via the DQ419 controller.<\/p>\n<h4>Next Steps<\/h4>\n<p>Next steps to get this machines running are as follows:<\/p>\n<ul>\n<li>Obtain a known good M7270 and install it in the MINC<\/li>\n<li>Hookup a PC running both PDP11GUI (to download a TU58 emulator bootstrap to the MINC, and to provide a Console terminal) and TU58EM (hosting a bootable RT11 TU58 image) to the MINC<\/li>\n<li>Download the TU58 bootstrap to the MINC using PDP11GUI<\/li>\n<li>Execute the TU58 bootstrap on the MINC (using the ODT command &#8220;10000G&#8221;) and check that RT11 loads on the MINC<\/li>\n<li>Hookup 1 or 2 standard (not DEC RX01 or DEC RX02) drives to the DQ419 controller<\/li>\n<li>Check out the DQ419 subsystem (ensure RX02 disks can be written and read under RT11)<\/li>\n<li>Use PDP11GUI to write the Bitsavers MINC 11\/03 disk images to the drive connected to the DQ419<\/li>\n<li>Boot the MINC from the floppy drive and checkout the MINC I\/O boards using the MINC software<\/li>\n<li>Repair the SLU0 and SLU1 connector wiring on the back panel, and arrange the 4 x 10-pin connectors on the DLV11-J appropriately<\/li>\n<\/ul>\n<p>The 2 serial cables that go between the MINC and the PC are DB9F at both ends.  But the ends are NOT interchangeable.  The MINC and PC ends are labelled respectively in black ink.<\/p>\n<h4>Board List<\/h4>\n<p>The MINC-11 has the following boards installed:<\/p>\n<table cellspacing=\"0\" cellpadding=\"10\" style=\"margin-left:10%;\">\n<tr class=\"bb\">\n<th>Board<\/th>\n<th>Description<\/th>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">M7270<\/td>\n<td>PDP-11\/03 CPU<\/td>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">M8044<\/td>\n<td>32KW RAM (28KW useable)<\/td>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">Dilog DQ419<\/td>\n<td>RX02 workalike board for &#8220;normal&#8221; 8&#8243; floppy drives<\/td>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">M7954<\/td>\n<td>IEEE-4888 GPIB Interface<\/td>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">M8659<\/td>\n<td>Grant Continuity Card<\/td>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">M8659<\/td>\n<td>Grant Continuity Card<\/td>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">M8043<\/td>\n<td>DLV11-J SLU Interface<\/td>\n<\/tr>\n<\/table>\n<p>Then in the instrumentation section:<\/p>\n<table cellspacing=\"0\" cellpadding=\"10\" style=\"margin-left:10%;\">\n<tr class=\"bb\">\n<th>Board<\/th>\n<th>Description<\/th>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">MNCKW<\/td>\n<td>Clock Module<\/td>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">MNCDO<\/td>\n<td>Digital Out Module<\/td>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">MNCAD<\/td>\n<td>A\/D Module<\/td>\n<\/tr>\n<\/table>\n<p>Then the terminator:<\/p>\n<table cellspacing=\"0\" cellpadding=\"10\" style=\"margin-left:10%;\">\n<tr class=\"bb\">\n<th>Board<\/th>\n<th>Description<\/th>\n<\/tr>\n<tr class=\"topjust\">\n<td class=\"center\">M8012<\/td>\n<td>BDV11 Terminator and Boot Module<\/td>\n<\/tr>\n<\/table>\n<h4>Console Cable<\/h4>\n<p>A small module hanging off the back of the MINC-11 back panel houses the 4 x DB9M connectors from the SLU.<\/p>\n<p>The top connector is for the Console.
