Virtual HP41 and Virtual HP-IL Message #1 Posted by Mike (Stgt) on 12 Sept 2012, 11:36 a.m. Is there a virtual HP41 that goes withChristoph Giesselinks Virtual HP-IL? Alas no, AFAIK. Or is there someone at it? Should I do it? (There is a 'IL add on' for the Nonpareil-HP41, but does it talk with ILPer/ILSope/etc.?) Well, the HP-71B (and Emu71/Win) is the better IL controller but I feel more comfortable with the HP41. Ciao.....Mike

It's a console (DOS) based program, but it quite a capable emulator. http://www.jeffcalc.hp41.eu/emu41/index.html Edited to correct link.

Re: Virtual HP41 and Virtual HP-IL Message #3 Posted by Sylvain Cote on 12 Sept 2012, 11:53 p.m., in response to message #2 by Howard Owen Yes but it's limited to it's own virtual devices inside emu41. Since MS-DOS does not have a TCP-IP stack, emu41 cannot establish a socket with Christoph virtual devices. One solution will be to share alternatively a LIF drive between the two simulated world (emu41 & emu71). A second solution requires 2 PIL-Box with a setup like this ... emu41 -> VCOM over USB -> PIL-Box-1 -> HP-IL -> PIL-Box-2 -> VCOM over USB -> ILPer -> other virtual devices

Google for packet driver. Quote: One solution will be to share alternatively a LIF drive between the two simulated world (emu41 & emu71).

Both are open source.

You are right. But what I meant was that Microsoft did not include a generic IP stack with a standard API that would have been included on all MS-DOS machine.

Re: Virtual HP41 and Virtual HP-IL Message #6 Posted by Mike (Stgt) on 17 Sept 2012, 1:47 p.m., in response to message #5 by Sylvain Cote Thanks for everybody who replied. Seems a tricky thing. BTW, TCPIP did work on DOS in some way as "we" used the HP200LX for eMail and such things quite well, with modem or via IrDA mobiles. Ciao.....Mike
