There are many RPL programmers in the club. Many of the active members own an RPL machine (I've never bought the 50G but I have a 28C, 48SX, 48GX and 49G). If it's user-RPL that you need help with then there are plenty of people to help. System-RPL might take a little longer.

The club started as a group to explore the undocumented bits of the HP41, the so-called 'synthetic programming'. There are still people around who understand that, who have their byte table to hand. Even people who program the HP41 in the processor machine code. So if you still have the HP41CV, the club can help you with that too (and all sorts of interesting manuals are on members' shelves...)

As I said, we cover a lot more than the HP handhelds. As an example, at the conference this year (the conference is by far the most formal and on-topic meeting) there were talks on the early days of HPIB (and the pre-history of it, including a mention of the Blackburn BIE2114 DVM.), repairing the HP9830, the HP35 (HP's first handheld electronic calculator), the DM42 (the HP42-a-like from Swiss Micros), etc.

If you want to come along, please contact the club (details on the website) or PM me for details of where and when. For obvious reasons we like to know if a new member is going to turn up.
