V41 Maintenance Release R9B
Like stated in some discussions, V41 R9A was not the end of my V41 efforts.

So what's new:

One of the main points is the session logic with the session file HP-41CX.lod as default. One of the changes in R9A was to remove the directory restrictions for .lod files. New is remembering the last session .lod file, so using HP-41CX.lod always as default has gone. With this in background I added also an MRU list for fast session changing. But next problem occured, V41 does not save sessions when loading a new one by default. So session loading got a request messagebox if the old session should be saved before.

A second interesting part is the <Backspace>-<ON> sequence for "Memory Lost". Because of design limitations inside V41 a 2-key rollover wasn't possible so far. By adding a 2-key rollover simulation in the keyboard handler the <Backspace>-<ON> sequence for reset memory can now be executed over the PC keyboard. Other <ON> sequences are used by the PANAME ROM. Because of usability problems a 2-key rollover simulation over the mouse isn't implemented.

From the technical aspect the implementation of the 1LB6 scope mode was an effort. In the original HP-IL implementations of Emu41, Emu71/DOS, Emu71/Win and Emu75/DOS the frame timeout is part of the interface simulation. In the changed HP-IL implementation of V41 R9B, the NUT CPU simulation is responsible for the frame timeout like in the real calculator. In Turbo mode a NUT CPU slowdown take account to this situation. The SCOPE command of the HP-IL Development Module is now working.

Some remarks to the SCOPE delay steps 0, 0.5, 1 and 1.5 sec. I recognized, when using one V41 instance as controller, ILPer 2.31 as device and one V41 instance as SCOPE device, that SCOPE delays with 1s and greater affects the <ON> initialization sequence of the HP-IL controller (V41 or real 41CX with PIL-Box) not recognizing any device. Doing the <ON> sequence with 0.5s or less delay the initialization is ok and then the SCOPE delay can set to maximum. I don't know if this behavior corresponds to a real HP41 with a HP-IL Development Module (00041-15043), I haven't this module.

With this V41 version I completed my entire task adding Virtual HP-IL to V41 I began in July 2018. Beyond this topic I made some adjustments and bug fixes. Further development is not planned at the moment.

The new version R9B is available on Warrens V41 product page.

RE: V41 Maintenance Release R9B
Thanks Christoph for your continued updates to this superb product, I'm sure it's a lot of effort but it's worthwhile!

After dome delays I'm now full on-board on R9A so will be doing this update ASAP..

Cheers,
ÁM
