j-hoppe / pdp11gui Goto Github PK

Hello,
I tried PDP11GUI on Windows 10. Directly after installation it was working fine with telnet-attached simh. I tried one of the tutorial examples and an own MAC file.

After that I restarted PDP11GUI and since then, the workflow from assembing a MAC file to upload it to simh does not work again. I even have re-installed PDP11GUI but this does not change the issue.

What I can see is that MACRO11 assembler runs ok and create a LST and a HEX file. Then from the log window i see that a file called "pdp11gui_deposit.sim" should be created in some temp directory (c:\users\spam\AppData\Local\Temp, my user is called 'spam'). This directory exists, but the file is not created. I suppose the content of the file are the bytes to deposit into simh.

Because the file does not exist, nothing is uploaded. There is no error message or so in the log.

What can I do to solve the issue? As said, deinstall and again install does not change the issue.

Here is the log output:

The RLE support in the aux driver code uses SOB, which is an EIS instruction and unavailable on older PDP-11s, such as the PDP-11/22, /05 and /04, or un-expanded /40s and /03s. This can make it seem like there is a hardware fault with the connected machine, when there isn't.

Workaround: uncheck the "Test RLE compression" button and press "Test" once. This will disable RLE compression for the entire session.

Aside from fixing the driver, it might be useful to move the checkbox out of the "Test" section and make this a global RLE enable/disable for the serial port, set at the time of performing any operation.

This appears to have been realised at least once before, but not completely resolved.

I can connect to my 11/84 with an FTDI USB/Serial cable under Windows 10, but not with a DSD TECH SH-RS232D USB/Serial cable that is based on the Prolific PL2303 chip. The DSD Tech cable works OK using PuTTY to connect to the 11/84.

I am trying to load the MSCP driver and get the above error message after the driver loads, but before the frame for imaging appears on the read/write images dialog. It will keep happening when I hit "Reset & open device".

Machine is an 11/23+ with ODT and 1,5MB of RAM
