hp110+ info

Still can't find manuals. But here's what I know and maybe people can fill in the blanks. First info - Base model is 45711E, supposedly that designates 110+, 512k ram, & modem. The memory drawer has a model 82981A, which googling suggests is 128k ram addon. There's a metal shield over the chips and I don't have the right torq bit to remove. Upon boot all the ROM ID shows BBBBBB. First question - going into system config lets me set the memory split between main memory and edisk. All choices add up to 896k. How does that square with 128k + 512k? Second info - The PAM menu shows the following application choices - DOS CMDS, HP reflection, VT reflection, Memo Maker, Time Management, and BASIC. However, opening up the software drawer shows the following chips in the following locations 82863K-Reflection1 (0L), 45504K-MemoMaker/TimeMgt (1L), 82862K-BASIC (4L), 45555K-1/2-ExecutiveCardMgr (5H), 45555K-2/2-ExecutiveCardMgr (5L), 45548K-1/2-Lotus123 (6H), 45548K-2/2-Lotus123 (6L). Second question - I assume the PAM menu selections for HP reflection and VT reflection are handled by the single 82863K rom. I am curious why the Executive Card Manager and Lotus123 don't show up in the PAM menu? Misc. questions - The built in battery is obviously dead and won't hold a charge, as the unit won't run at all without the AC adapter. Every time I boot up though, it asks to reformat the A drive due to memory loss. More importantly, it has lost the date/time and system config settings (memory/edisk split for example). I'm curious if the date/time and config settings are kept by a different battery I may need to replace, or if all of the above is maintained by the single battery. I will have to hunt up a new battery. This 110+ is a really nice box! I'm quite fascinated by the built-into-rom HP terminal emulator (dumb terminal emulation won't do) as well as VT terminal emulator and serial port, all in a small package! Sweet! Thanks for any pointers! Jay West
