It seems to me that this home made device was created to save money. Datapaks used to be relatively expensive, but you could buy bare eeprom chips much more cheaply. This thing simply allows you to swap out the chip from the "datapack".
 
I would not really call it an eeprom programmer. When Psion first designed the datapack circuitboards, they permuted the address and data lines in some way that allowed for the easiest circuits. This means however that if you take the eeprom out of a datapack and put it into any non-Psion device, its contents will seem scrambled. This device directly connects the datapack circuit to the eeprom without (un)permuting the lines, so you cannot directly use the eeproms this creates in non-Psion circuitry.
 
That isn't to say that you cannot possibly use this as an eeprom programmer. You could create software for the Psion that reads in a file (e.g. via the comms link from a PC), applies the necessary permutations, and writes that to the eeprom, after which you can use that eprom in a non-Psion device. It's just that it does not seem likely that this was ever done here.

Dear Jaap (and anyone else using the The Organiser Developer Manual)
 
The manual has the typo MIDS instead of MID$
 
POKEB $2187+I%,ASC(MIDS(item$,I%,1))
 
But now it is good for those using the online version.
 
Sincerely
Martin

Dear Daren (and others interested)
 
Please see the User Post Thread
 
http://forum.psion2.org/YaBB.pl?board=UserPost;action=display;num=154609 5336
 
Also Jaap's web site - Change Log page - suggests he has added the photos and ROM image, I can't see them yet but no doubt will soon.
 
Sincerely and in good faith
Martin

If the Datapak is OK, it is normal to wait for the software to tell you when to insert it.  The Organiser will try to format a blank pack, and if the software is expecting a blank one... so just wait for the software to tell you to insert the pack.

Raymond,
I use the developer tool running in DosBox and find that to be a solid solution on a 64bit platform. Run the CL.EXE application first to open communication with the Psion and then do the MAKE. Sometimes it is necessary to use the '-a' (append) switch, but I've not looked into why this is the case.  
Good luck, let us know how you get on.
Regards,
Dave.

Thank you, it hardly surprises me. Owning as much old electrical equipment as I do, replacing caps has become par for course lol. When I first heard the LZ whistle, I guessed it would be cap related. The Sega Game Gear sometimes suffers from a similar problem, too often it fails all together, resulting in no sound what so ever. SMD caps are usually more prone to failing than through hole caps.
 
Anyhow I hope the info on the website helps someone.
