Handspring Visor Memory Upgrade
Hey Rob
I got the Visor pro today and took one of my Visor Deluxe’s apart and realized that my assumption about the back plate was wrong I was expecting just a back plate with the battery cradle and a wire plug into the main board.
Instead, there are two main boards one in the back plate which half of the dual battery terminal is connected directly to.
I further read your attempt to upgrade a solo to a deluxe did not last long, I was looking to see if the memory board for the Visor Pro would go into the Visor Neo upgrading the Neo to 16 MB which would be perfect for me, as the Neo has the AAA batteries and the 33 MHZ CPU. as well as the palm os 3.5 etc…
But after reading about your problems going from 2 MB to 8 MB and the unit dying, I am not so sure I want to try swapping memory modules and switching jumpers even if it is possible.
Thank you for the replies.

Hey Rob,
I just won the Handspring visor pro on eBay for 9.69 and 11.23 shipping.
I am going to try the switch to aaa batteries anyway, it may not come up or maybe it will but since I was all ready committed with a bid on the Visor Pro, I am going to give it a shot, it might even be that the terminals were kept the same so they did not have to change them on the mother board, and the aaa battery terminal will plug right in, if not I can do a quick cut and splice from the lith-ion battery wires to the aaa battery wires.
I’ll let you know what happens when I get it in the mail.

Visor hand held batt at cap Critical threshold
Visor Neo 3.0 1.6
Visor Pro 4.2 3.5
This is not looking good, while the outside and certain functions are the same, the inside hardware is enough different that the voltages will not be right.

Thank you, I have bid on a 9.69 visor pro on eBay
I am hoping the only difference will be the battery and the 16 MB memory.
all of the visors look identical on the outside, same screen same buttons and arrangement, the Neo I have which is the model below the pro has aaa batteries and only 8 MB of ram, but the same look and the same 33 MHz CPU.
I am thinking that the pro just upgraded the memory and went with a lith ion Battery.
When I get it and delve into them I will report back.

«« Back To Stats PageHey Rob, I have two Visors and one Neo, I want the aaa battery pda, so the Neo with the 33 mhz and 3.5 palm os is great right now.
The Visor pro is the last in the line but has 16 mb memory while my Neo only 8.
do you think swapping cases could be doable? visor pro innards into a visor deluxe case, ditching the lithium ion for the conventional aaa batteries?
I am handy with a soldering iron and could cut the existing aaa battery wires and the wires on the lithium ion battery splicing them together if need be. so that I end up with a Visor Pro running on aaa batteries.
