Hi, I have Model 3, with a couple of 5.25" floppies that I'm looking for some help with. I think it was originally someone's parts machine (mismatched components, missing screws, etc), and it has one Tandon TM100-1A (drive 0) and a Texas Peripherals (TPI) clone (drive 1). Both drives struggle...

Cool, thanks. This has been really helpful. I have a related question, and apologies for my Linux background. mx1600 reads the file name to assemble from what I would know as stdin. In an RT-11 batch, command or ind file is it possible to take an argument from the command line and pass to...

Thanks, this is really helpful. Apologies for my naivety, but could you clarify what you mean by "small monitor version"?

Hi, I'm having a bit of a fun getting my head around the PDP-11 memory model, hopefully someone can help. The setup is as follows: I'm using SIMH to emulate an 11/53 with 256K of RAM. This is running RT-11 v5.0.3 with the XM monitor from an RL02. I'm trying to run a cross assembler written...

The heart of the SFMT is a Teas Instruments TMS-1100. MP1312 is a reference to the particular mask ROM program, instruction PLA and "O" output PLA configuration requested by the customer, presumably this was originally Gakken in this case. In the case of the MP1312 used in the SFMT both the...

Hi all, I'm looking for information about the Sigma Information Systems 400185 QBUS dual hard drive controller. I believe that it may also be known as the SDC-RL11 or SDC-RLV11. I have found the manuals for the SDC-RLV12 - 400250 and SDC-RLV112 - 400320, however, when it comes to the 400185...

Hey, Apologies I'm a bit of a PDP-11 noob. I'm trying to set up Simh on Linux running RT-11 v5.3 and use VTCOM to communicate over a physical serial port (actually a USB/serial adapter) to an RS-232 peripheral that runs at 9600-8-n. Having installed the O/S on a virtual RD52 with the XM...
