HP 95LX: Derive Maths Programme
I have a Derive version 2.5 application card (also works on 100 & 200LX).

Does anyone know if there were any updated cards with a later version number?

RE: HP 95LX: Derive Maths Programme
At the time of this review the latest version was 4.13.

P.S.: Not sure whether this was ever available as an application card for the HP-200LX though, so your question remains answered.

But is that version on an application card?

I think 4.13 is a miss-print for 3.13.

Very unlikely to ever have been available as an HP-200LX application card, I fear.

Quoting from the review:

"Speedwise, the new version seems about the same as the 3.x versions."

This might imply that one was version 4.13 indeed.

RE: HP 95LX: Derive Maths Programme
I tried, at the time, to keep up with developments in Derive & have a version 3.13 running on a 200LX, it won't work on the 95LX.

I guess versions later than 3.13 won't run on the 200LX - does anyone have a version 4.x loaded that functions correctly?

My original query was only concerning versions on application cards.

It seems from this archive that Derive 4.11 can run on the 200LX: DERIVE with Acrospin for 200LX 4.11.

Do you have a picture of your Derive application card?

Thanks Didier, yes 4.11 works OK on 100LX.

Also, of course, on my 200LX. Merci beaucoup, Didier!

Were there any special drivers that you needed to install (for the screen, perhaps) in order for derive to run? I remember trying to get an old version (was it 5, perhaps?) to run and could not. I assumed that as long as you had a DOS environment (which the LX does, sort of) that it would just be a matter getting the appropriate display drivers. However, I never got it to work (due to lack of drivers.)

RE: HP 95LX: Derive Maths Programme
I don't remember where I got it from, but this link says this Derive version is optimized for the HP-200's CGA monochrome display. Unfortunately the dark stain in the center of my 200LX grew to an extent that has made it unusable. I replaced the display once for the same reason.

Good luck!

I am a bit slow to join, but I have already spent quite sime time get hold of version 4.13. All I found was version 4.11, which is also the latest version mentioned by the derive user group. So 4.13 was either indeed a typo or very rare.

BTW, derive for dos also runs quite well in a dos box on my android tablet. I prefer it over the current alternatives (e.g. xcas, geogebra).
