The files contained in this package are used to IPL the Hercules emulator. Taken from the Hercules FAQ: 3. Alternatively, you can download the mftr33.tar.gz package which contains a minimal MFT system on a 3330 image, with some minimal documentation. The configuration is that of a 370/145 with 2 megabytes of main storage, running OS/MFT Release 21.0, with several volumes of pre-loaded DASD. 2 program partitions (P0 and P1) have been genned. There is no working TOD clock, and no SMF. Volume DLIB01 which is specified does not exist in the zipped file, but can be created using a plf file with the CDROM of OS/360. DLIB01 can be commented-out from the config (cnf) file if desired. The mftr33 package also includes the IPL text and program for the standalone IBCDASD program as file "ibcdasdi.rdr" which can be used if desired.
