Hello,

now that my EAE option is running the maindecs, I'm searching for other software using EAE.

F4 with OS/8 was the first software using my EAE, because the F4 compiler tests the hardware and uses EAE or FPP when available. But what else?
After some reading and searching I also found this:

-Basic for OS/8 has to be configured to use the EAE. This is described in OS8_Language_Reference_Manual_Mar79.pdf in chapter 4. You have to change some files from the basic installation. You can compile the sources and load the result, then save some files. After the procedure as described basic uses the EAE and calculating is much quicker.

-FOCAL69 worked fine with an 8 Word patch, you can toggle in after loading the program. This is written in Advanced_FOCAL_Technical_Specification_Apr69.pdf in chapter3.5.7. It's fun to test this. This also works if you load the 4-word patch for longer floating point numbers. I noticed that this worked with FOCAL71 in a quick test too.

Alternatively you can use a patch from DECUS (focal8-313) for FOCAL69, I found on Vincent's site: http://focal8-313. This again worked with the 4-word patch.

-UW-FOCAL I found on the v3d.rk05 image from pidp8 project seems to need EAE. Before I had my cards ready, I was thinking this UW-FOCAL was defective, it even was not able to calculate 1+1....

If you know more software using EAE please let me know!

I just found this thread in a google search.

The pidp8i project, in the media/os8/subsys directory contains two DECtape images: uwfocal-v4e-1.tu56 and uwfocal-v4e-2.tu56.
The first one, uwfocal-v4e-1.tu56 contains buildable source for UWFocal. I've not dug into tit too deeply, but I believe a non EAE version
can be built, based on a comment I see in 16KCPR.PA:

Code:
/       ASSEMBLY INSTRUCTIONS USING PAL8-V10:

/       UWF.BN<16KCPR,12KFNS,8KFIO,8KFPP,16KLIB/L/K=100
/       EAE VERSION:      8XFIO,8XFPP
