HP41CL 218 registers instead of 219
Hi all,
After changing the batteries in my HP41CL, I waited a bit too long and got a memory loss. No big deal, right? However, upon reinstalling it, I decided to plugin the Sandmath 4.4 module in slot 3. Is it normal to only have 218 registers instead of 219 after resetting my HP41CL? Is it because of the 804040-8120 YPOKE? I have YFNP in 1L, PWRL in 1U, Time module in 2, 41AD in 2, SM44 in 3, Card Reader in 4L, EENG in 4U. Please enlighten me as it’s the first time I use 804040-8120 (if I don’t, I get “NO LIBRARY” upon restart after plugging in the Sandmath ROM). First time user of that ROM as well. I hope my explanation is clear... Thanks. Engineer & Senior IT Executive 2x HP41CL, HP41CX, HP48GX, HP50g, 2x82162A Printer, 2x82143A Printer, 2x HP-IL, 2x Card-Readers, PIL-BOX. |

As someone replied in the earlier version of this thread (unless I imagined it) the Sandmath module allocates a buffer, which would take at least part of the first free register, hence the loss. The YPOKE command is simply a shorthand way of loading LIB4 into PAGE-4, this does not affect free RAM space. --Bob Prosperi |
