I've been looking at the specs for the Omnigo 120. Since there is no
metion of an upgraded CPU vs the 100, I assume that is is still the
16MHz Vadem VG230. However, Vadem has a newer and faster (32MHz)
computer-on-a-chip CPU, the VG330. I'm wondering if the VG330 is
pin-compatible with the VG230. Anyone know?
For the HP 200LX palmtop there are companies who are doing after-market
memory expansion upgrades. (voids the HP warranty, of course) Has
anyone heard of someone adding more memory directly into an Omnigo?
Opinions as to whether it would work? I.E. Is there any room to put em
in and would Geos use the mem as additional internal ramdisk?
Maybe someone who has the developer's kit would know about the Geos part.
With all of the DOS hacking on the OG I thought that the following info
was interesting. This is a text fragment from the Vadem VG230 data sheet
on the new Vadem web page. (^^^=empahsis is mine)
"The LCD Controller supports all CGA Text and Graphics display modes. With a
400-line display, AT&T 640x400 two-color graphics mode is also supported.
For smaller panels, the controller provides hardware support for windowing
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
into the CGA or AT&T frame. "
Has anyone made any use of the "hardware support for windowing" in the VG230
to do the CGA-DOS modes published so far?
