RE: If I were to buy an LED model...
Here's the ol' 15-puzzle solvability checker, ported pretty much directly from Don's 65 version. There are a couple of notable changes:
1. No labels, so all GTOs are line-number-based. 2. R/S doesn't terminate digit entry, so there's an ENTER in step 4 to explicitly terminate entry (otherwise the next step would modify X rather than lifting the stack first). 3. y^x isn't super precise, so the y^x call is followed by .5 + INT to round to the nearest integer. To run it: Enter the row number of the blank, press R/S, then enter the tiles left to right, top to bottom, with R/S after each one. Code: 01 CLR REG |
