Yes, I can. It is LPC2478.

Thanks again Timo!
I found my issue; it was the location I'd assigned for the stack on entry to the ISP. When I moved the stack to 0x40000100, it all worked perfectly. Thanks again to all who responded.
Regards,
Dave

For those interested:
Some other things I had to do to get IAP re-invoke ISP to work on the LPC2468 included:
MAM=0 (disabled)
CLKSRCSEL=0 (RC osc)
PCONP = defaults (ISP uses a peripheral I had turned off)
I did not seem to need to set legacy mode for GPIO (clear bit 0 of SCS). I tried it with the bit set and clear and it worked both ways.

ISP doesn't use the IO ports so shouldn't be an issue.
An additional setup I had to do on LPC2136/01 was set the UART FDR to its reset default value
(0x10).
