Boris, I am very interested in PDP-11s and laboratory data acquisition with A/Ds etc. I have a MINC-23 (upgraded to an 11/73) that I’ve put a SCSI2SD card in and run RT-11, and RSX11M. Recently the RT-11 FEP/FRP and RGL software packages were recovered from a couple RL02 packs in Austrailia. Also, on another PDP-11/73 I converted a ADV11-A (18 bit) to a ADV11-C (22 bit) and have it talking with the Kseries routines under RSX11M+ as well as to a M+ A/D driver that I wrote by combining code from David Cutler’s AD01 RSX11M Driver with Lee Gleason's M+ BM180 driver for the PiDP-11/70 that Adam just mentioned in his post. Certainly the I2C devices could be extended to create some Actual I/O device with chips like the ADS1015 which is available on a small board from AdaFruit that would be easy to stick in a PiDP-11. https://www.adafruit.com/product/1083 I would be VERY interested in getting a copy of your PDP-11 code for data acquisition with A/Ds, DIOs, etc. Thanks, Mark
