I should be sleeping.... Anyways, this looks really cool, here is a mechanical translation of the readme from German to English... ( <a href="http://translate.google.com">translate.google.com</a>)<div><br></div><div>-----------</div>
<div><div>9.8.2005 Christian Corti</div><div><br></div><div>Kurzanleitung zum LGP30-Simulator - Version 1.70</div><div>------------------------------------------------</div><div><br></div><div>1st Files</div><div>----------</div>
<div>The simulator essentially consists of the main program LGP30SIM.EXE.</div><div>In addition, there are subdirectories with the extension. TRM, in which</div><div>"Snapshots" of the drum contents are stored. The simulator can</div>
<div>be produced and accessed.</div><div><br></div><div>LGP30SIM.EXE main program</div><div>LOCHSTR / directory with the tape files for the LGP-30</div><div>START.TRM / directory with the drum contents "START", 9.0 (Bootstrap)</div>
<div>and 10.4 (Monitor) are already on the drum.</div><div><br></div><div><br></div><div>2nd Start</div><div>--------</div><div>In the directory containing the files just start LGP30SIM simulator. It appears</div><div>then the console screen. When you call the simulator may, if necessary</div>
<div>more options with the command line are passed. These are:</div><div> /? Show options</div><div><br></div><div> / S Enable serial console</div><div> Thus the input / output of a simulated Flexowriters</div><div>serial port redirected. The start button on Flexowriter</div>
<div>is by BREAK (eg simulated BREAK key on a V.24 terminal).</div><div> The syntax is:</div><div>/ S: port, baud, par, bits, stop</div><div>: port number of the COM ports (0, 1, 2, 3)</div><div>baud: baud rate (e.g. 9600)</div>
<div>par: parity (N = none, E = even, O = odd)</div><div>bits: Number of data bits (7 or 8)</div><div>stop: Number of stop bits (1 or 2)</div><div><br></div><div><br></div><div>/ P Enable output to printer</div><div> The output of the simulated Flexowriters after PRN (the</div>
<div>Standard printer under DOS sent). The input is still</div><div>with the keyboard on the computer.</div><div>Syntax:</div><div>/ P: 1</div><div><br></div><div> / L Slow simulation</div><div> This is the execution speed of the simulator about</div>
<div>to the real speed of the processing set LGP-30.</div><div>Even on a 4.77 MHz 8088 system is the simulation clearly</div><div>faster than the original system.</div><div><br></div><div> / Z Delete default drum content</div>
<div> The drum is running the simulator is cleared and</div><div>does not contain the last state of the simulator run.</div><div><br></div><div><br></div><div><br></div><div>3rd Operation</div><div>------------</div><div>
After startup, the first thing the console screen of the simulator. The</div><div>Console is divided into several areas:</div><div><br></div><div>- Status (first line of the screen)</div><div> Here is the current state of the simulator is presented, the following are</div>
<div> possible:</div><div> STOP - execution is stopped</div><div> PAYS - program or command is running</div><div> OVERFLOW - execution was stopped because of an overflow in the accumulator</div><div> ENTER - Program expected input from the simulated Flexowriter (keyboard)</div>
<div><br></div><div>Also appears on the left side when reading a punched tape</div><div> (READ from file) '', in writing accordingly, 'WRITE'.</div><div><br></div><div>- Register Display (top right)</div>
<div> The registers display corresponds to the ad on the Oszilloskopröhre</div><div> LGP-30. It can be seen: instruction counter, instruction register and accumulator.</div><div> Just beneath the mask of command, track, and cell is indicated.</div>
<div> To the left of the mask is the command that is currently in command</div><div> register is, in disassembled form, with an empty register, therefore</div><div> Z 0000th</div><div><br></div><div>- Operating (top left)</div>
<div> With the specified key can be changed; operation, the</div><div> current state is highlighted. You can choose between normal,</div><div> Single operation and input of hand switch. In the third mode can be</div><div>
to enter it by pressing the Enter key a bit in the accumulator,</div><div> with either 4-bit or 6-bit is input, depending on the status of the</div><div> Press the "6-bit input.</div><div><br></div><div>- Dump (middle)</div>
<div> The field itself can dump the contents constitute the drum. It</div><div> appear always 8 cells. Links of the bitwise representation</div><div> here is the address of the cell in the form [trace cell], again</div>
<div> left of the command that is in the cell (see mask).</div><div> Using the cursor keys to navigate within the drum.</div><div> The key assignment is here to help on the left.</div><div><br></div><div>- Panel buttons (on the bottom of the screen)</div>
<div> The keys of the LGP-30 are realized with the keys F1 to F10. Similar to the</div><div> LGP-30, only buttons that are labeled brightly, in the current operating</div><div> a state function.</div><div> </div><div>
The output of the Flexowriters carried on a second screen, with the</div><div>by pressing Alt-F2 can be changed. Similarly, there appear</div><div>all input from the keyboard. Go to console you get with Alt-F1.</div><div>
<br></div><div>One of the most important programs on the LGP-30, the program is 10.4, with the</div><div>can be read in other programs or programs with which you assemble</div><div>can (with Adreßumwandlung). To this end, already has a snapshot</div>
<div>the drum made with a loaded 10.4, which is called START.</div><div>This is loaded with Ctrl-L. Similarly, Ctrl-S can be the entire</div><div>Drum tab including save.</div><div><br></div><div>The operation of the simulator is below with an example</div>
<div>are explained.</div><div><br></div><div>4th Shortcuts</div><div>---------------</div><div><br></div><div>Alt-F1 console on the display of the screen</div><div>Alt-F2 representation of the input / output on the screen Flexowriter</div>
<div>ESC simulator exit (after inquiry), or</div><div>Input to the accumulator exit prematurely (during ENTER)</div><div><br></div><div>Ctrl-L: Load Drum Content</div><div>The name of the drum, only the actual name without suffix</div>
<div>. TRM can be specified.</div><div>Ctrl-S: drum content store</div><div>For the name the same as above. The name is at the ending</div><div>. Supplemented TRM and creates a subdirectory, which then</div><div>two files: REGS.MEM and TROMMEL.MEM.</div>
<div><br></div><div>Alt-E: results of the input</div><div> Possible input sources are:</div><div>Keyboard (T)</div><div>File (D), it should be the content of a perforated strip located.</div><div>The option paper tape (L) works only with special hardware</div>
<div>and therefore can not be used.</div><div><br></div><div>Alt-O: Switch the output</div><div>Possible output devices are:</div><div>Screen (S) to see with Alt-F2</div><div>File (D) so that the output can be redirected to a file.</div>
<div>For the tape option is the same as in the paragraph above.</div><div><br></div><div>Alt-T: Trace</div><div>When the trace function are all the commands executed</div><div>are logged to a file, together with the register contents.</div>
<div><br></div><div>N Normal</div><div>This is the normal operating mode of the LGP-30.</div><div>E Single Operation</div><div>In this mode, press Start at the respective next</div><div>Command executed.</div><div>H input by hand</div>
<div>In this mode via the keyboard input of an accumulator</div><div>. Done With the RETURN command is started, then it is with</div><div><ESC> Ended.</div><div><br></div><div>F1 Start</div><div>F2 counters - delete the program counter is set to zero.</div>
<div>F3 command type - the content of the accumulator is in the</div><div>Instruction register transfer.</div><div>F4 command - execute the current command in the command register is</div><div>executed.</div><div>F5 .. F8 No Halt - These are the conditional breakpoints in a</div>
<div>Application can be queried.</div><div>F9 6-bit input - instead appears with four bits of each character in the</div><div>Entry with his full 6-bit code in the accumulator.</div><div>F10 jump - conditional jump, the query using the-T command</div>
<div>can be.</div><div><br></div><div>The keys F5 through F10 work as well as an input, the simulator</div><div>expected.</div><div><br></div><div>A. Sample</div><div>-----------</div><div>Translation of the lunar landing program using the ACT-V compiler and</div>
<div>subsequent start.</div><div>There are following this tape (both as a file on the computer</div><div>filed): V-ACT requires compiler, ACT-V Basic subroutines, source code of the</div><div>Moon landing, root subroutine.</div>
<div><br></div><div>1st Loading the drum with a program loaded already 4.10</div><div> Ctrl-L -> start <return></div><div> As already mentioned only "start typing", not as "Start.trm.</div><div>
<br></div><div>2nd Reading of the ACT-V compiler</div><div> Alt-E -> D <return> -> lochstr \ act5 <return></div><div> </div><div> The message "keyboard input" changes to "input file".</div>
<div> If the file is not found, this is indicated with a short tone</div><div> and the display does not change.</div><div><br></div><div> Then:</div><div> N (switch to normal mode)</div><div> F1 (Start)</div><div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi,<br>
<br>
cool "box", this LGP-30 ... the Stuttgart University (where the software download links below point to) has/had a fully restored and working model (I've seen it in operation when I was there a few years ago - quite impressive, but no chance to "play" with). In contrary to most other computers of that time (the 50s, remember !), it was designed for individual use - one of the first (or the first ?) "Personal Computers" ! It occupies the space of one single desk only (instead of a full room, or several cabinets ...), plus the typewriter (including the paper tape reader) for the operator (so, no bulky IO-Devices), can be operated on a single-phased standard wall socket (1700W power consumption), and handled by "relatively unskilled" people, as the manual states :-)<br>
<br>
Talking about manuals - the full maintenance manual is here<br>
<a href="ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/docs/WHB.pdf" target="_blank">ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/docs/WHB.pdf</a><br>
(pity it's in german, I didn't find any english version yet)<br>
<br>
<br>
About loading the "tapes" - AFAIK, the system needs either manual input of a program, or a bootstrap loader has to be keyed in and stored on the drum (permanent storage ... even survives a power down - if the correct shutdown procedure is observed ... nothing new in Windows, see ?) before it could read any paper tapes.<br>
<br>
I don't know if the emulator comes with that loader already "built in", but that might be one item that's missing. Also, I am not sure if the tape files (.TX) are in the correct encoding (Flexowriter vs. ASCII code).<br>
<a href="ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/papertapes/Utils/README" target="_blank">ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/papertapes/Utils/README</a> states some info about that, but gives no clue if any conversion is required before they can be used with SIMH.<br>
<br>
<br>
Christian Corti (of UNI Stuttgart) wrote an emulator for the LGP-30 (available from the above FTP server as well), and I assume it can read the files as they are. See here:<br>
<a href="ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/simulator/lgp30sim.zip" target="_blank">ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/simulator/lgp30sim.zip</a><br>
<br>
and consider reading<br>
<a href="ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/simulator/lgp30_en.txt" target="_blank">ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/simulator/lgp30_en.txt</a><br>
because the ZIP contains the German doc only ... and the simulator is in German as well :-(<br>
<br>
Btw, the ZIP contains all the papertape files referred to in the other links, plus some more.<br>
<br>
See the Example section in the above TXT to get an idea how to operate the LGP-30 as "unskilled operator" :-)<br>
It's not just click and run ... think of a programmable pocket calculator, to get some idea of handling the LGP.<br>
<br>
<br>
I did try the example (running the simulator on a XP system in a standard CMD box): Loading and compiling Lunar Lander (requires the compiler, compiler component routines, sqrt subroutines and the program itself to be loaded and run in the correct order), then running the program - it works fine !! Really cool to run a program that is 50 years old ... absolutely amazing !<br>
(remember to key in all positive numbers with a leading + sign, like +100 - and don't press ENTER after the input. Hit F1 instead, to continue execution).<br>
<br>
If you need further hints, please let me know.<br>
<br>
Getting this simulation to run might give you a clue how to work with SIMH, and if not, you at least have something operational to show :-)<br>
