I updated the patch in the beginning of the year, and iirc it worked: https://github.com/svenschnelle/qemu/tree/pciia

I finally calibrated my 744A last week, and discovered a few things while doing so , and decided to share a few tips in a video  https://youtu.be/wSqTj4gGCJU

Here are the main points :
- Supported ISA GPIB cards : https://www.eevblog.com/forum/testgear/automating-tektronix-field-adjustment-software-for-tds-oscilloscopes/msg1388658/#msg1388658
- CVR calibration does NOT absolutely require a metrology-grade DC calibrator like the DP8200, EDC 501 etc. But does need something better than just a lab PSU
- CVR calibration needs +- 9.5V at the highest setting (not 104V as the service manual indicates) ; look at your "CVRCAL.500" file to confirm
- HF cal needs 505MHz for a 500MHz scope, at +16 to +17 dBm. Many signal generators cannot do this, but a simple RF amplifier will do the trick.
- HF cal : watch out for lossy coax cable (e.g. RG58 ) ! Even 0.6dB of loss caused problems. Manually compensating that loss worked OK.

How is you project for automating the FAS 'Router' advancing?
Do you have any news, more details?
