Psion P250 ?

sort of continuing from the last one (still no further forward )

I now have P250 :

Now with a 128k dataPak, it's a square chip not a eprom like before.
The prog on it is some kind of timesheet V3.4 dated 1986 (password was PJ I think...)

again, does this handheld computer have a built in OS or all from the dataPaks??
I ask, as when I take the dataPak out, turn on, it just says "Data Pak?" , which is a pain as burnt a games Pak, so still can't play it!

so, which OS image do I need to burn to a 27128 (16k) eprom, so can get menu, then load the games Pak

[vanpeebles]

Not again!!

On that top picture, what other programs are on the menu?

[CMcDougall]

Only the Cipher timesheet prog, so yes very boring

[vanpeebles]

I still think your best bet is to get a really cheap XP.

£20 for an LZ! With datapak, bargain! Then you can code the unlock boot on that and get your other two working

[CMcDougall]

missed that, but don't really want to spend any money on them as don't mean anything to me from BITD

All I need to know is does this need a DataPak in one of the two slots for OS, or is the OS built in to bare Psion P250??
If needs a DataPak inserted, what OS should I burn to now 2 useless packs full of old data that's not required.

[vanpeebles]

The OS is on the Psion, but the P250 looks load a program from the carts.

The P250 (and P464, and all other POS models) can be patched to run as normal Organisers.

Jaap's Pos2Org will do it for 2-line (CM/XP/P250) models, there's also one for the P464 that I can't find at the moment.

organiser2.com is now the place to get help with these little guys.
