Custom ROMs for HP Portable PLus

[pamphonica]

Thanks Dave, I now have the Edisk, Image and Burn utilities on the PP, I just didn't realise that the suite of three utilities was called VGER! Now I have found the VGER manual, I can proceed.
For those who follow on behind, a good scan of the VGER suite document is available on J-F Garnier's site: http://www.jeffcalc.hp41.eu/hpplus/files/vger.pdf
I wish I had found that manual at the outset instead of trying to blunder my way through!
My other nice discovery today is that I can simply transfer files from my PC to the PP using MS-Dos formatted disks and my 9114A disk drive. Actually a lot simpler than DOSbox and Ilper.
thanks all,
Jeremy
