Wuite possibly. But WIndows was sold as an HP product for the HP150 (I
have it, original disks and manual).

No (in fact you could say it's the reverse, the HP150 always has the
touchscreen, on the 150-II it's an option).
The 150-II is quite different from the 150. It's in an almost cubical case
with a tilting CRT (like some of the later HP termninals). The CRT is 12"
(the 150's is 9") It has 4 vertically-positioned expansion slots (the 150
has 2, horizontally positioned). The 150-II uses HP-HIL for the keyboard
and touchscreen (and you can add a mouse on HP-HIL too). There is no
optional intenral printer on the 150-II. It has a power output socket for
the 9123 diosk drive. It can officially take an 8087 coprocrssor card
. I have an idea there are even a few software incompatabilities
between the 150 and 150-II
Electronically it's a complete redisign, with a lot more custom chips
than a 150.
 What a kludge. The 150-II has an 8088 on the mainboard, used in
'minimum mode', which means some of the coprocessor signals are not
available. The coprocessor card contains an 8088 in 'maximum mode', the
8087 and some interface logic. It disables the 8088 on the mainboard....
