HP19BII classroom display - Kees van der Sanden - 08-05-2018 06:13 PM
Hi,
A few days ago I received a HP19BII classroom display.
See: my webpage.
Are there versions build connected to the HP28 model?
What other models of this type of classroom display were build?
Kind regards,
Kees

Another style of classroom overhead projection tool was made for the HP-30S; one has been listed on eBay for many months:

Curious that they chose this model IMHO; though inexpensive, it was never particularly popular.
