<ref group="nb" name="NB_ORG">In most versions of [[CP/M]], the start of the [[Transient Program Area|TPA]] was at offset +100h, only preceded in memory by the [[zero page (CP/M)|zero page]] at offset +0h. Some versions differed for hardware reasons including CP/M for the [[Heath H89]], where it started at offset +4300h (for compatibility, a Magnolia Microsystems hardware modification existed to map out the ROMs at +100h after startup), or CP/M for the [[TRS-80 Model I]] and [[TRS-80 Model III]], where programs were loaded at offset +0h.<!-- https://web.archive.org/web/20211213154548/https://groups.google.com/g/comp.os.cpm/c/RMWG4qSdbM0/m/UGll0BzoiW0J --></ref>
