/* NEWCPM.COM */
====NEWCPM.COM====
* NEWCPM.COM is a normal COM file. It is loaded like a normal COM file. It resides in memory in bank 0 but configures a 61K CPM in bank 1 and transfers control to it. It remains in bank 0 and implements parts of the 61K CPM BIOS.
* NEWCPM.COM sets up a BIOS jumpblock in page C7 at &FC00. This calls into the resident NEWCPM.COM code in bank 0
* NEWCPM.SYS is first loaded to B00 in bank 0, it is later copied into bank 1 to it's correct location.
TPA upper address is &F300. BIOS jump is at &FC00. Code after &FC00 is part of the BIOS in bank 1.
