Just downloaded MPLAB 6.40 and in the Picstart+ notes I found the following - its not available for sale on the Microchip site yet but should be a nice upgrade to my Picstart - I can finally use the hundreds of 18F1220's that I bought ages ago. If anyone has any more info about this upgrade then please let me know - I'm dying to get going on the 18F series. Cheers Dom 4. What's New in SW v3.40, OS v4.00 ----------------------------------------------------------------- **************************************************************** MPLAB IDE v6.40 and PICSTART Plus SW v3.40, OS v4.00 support new PICSTART Plus Processor Upgrade Kit!!! **************************************************************** This release supports the new upgrade kit for PICSTART Plus that allows you to install an upgrade board with a flash device, instead of a PIC17C44, thus making future upgrades as easy as downloading a new programmer operating system. Requirements: For the kit to work, you must NOT have a PICSTART Plus unit with an assembly number ending in R4 or less. Units with an assembly number ending in R20 or greater, or with a sticker stating "Flash Upgradeable", have already been upgraded.
