CBT Tape V249 and Older Archives
These are old versions of the CBT tape and most people will want to download from the current CBT tape. These "golden oldies" are kept here for those experts who want to revive an old utility that has perhaps not yet been updated to work properly on ESA or for the curious. They are also proving to be of particular use to the those working on freely distributed OS/360 operating system which may be run under the freeware Hercules 370/390 Emulator.
The oldest CBT tapes we have copies of in AWSTAPE format (You will need Hercules, P390, etc to read or use file 533 VTT2TAPE utility to convert it to a real tape). These very oldest of CBT tapes are primarily of interest to MVT/MVS 3.8 hobbyists using Hercules.
CBT Base Tape V249 Created July - 5 - 1985
The files are all packaged with PKZIP and are in EBCDIC so you download from here, unzip, upload as Binary (No EBCDIC to ASCII translation) to your mainframe to an FB80 data set. All data sets are suffixed .XMI and are in XMIT format so you will need to do a TSO command RECEIVE INDATASET(???) where ??? is the file you upload to transform it back to useable file. XMIT format insures that all the odd data set attributes are preserved. The older CBT tapes had many sequential files with VB255 or FBA133 and other non FB80 formats. You will need a utility to unzip (decompress) the .ZIP files and I suggest either PKZIP or WinZip.

File 1 is a complete index and guide to what is on the tape so if you do not already have file 1 for the current version of the tape you will probably want to download it first. It is available below in several formats so you can use the one that is most convenient.
