Here are the MINI-UNIX files. TAPE0.BIN The standalone tape to disk program TAPE1.BIN The BIN disk (RK05) TAPE2.BIN The SRC disk (RK05) TAPE3.BIN The MAN disk (RK05) When booting TAPE1.BIN, type rkmx at the @ prompt. I also uploaded MXUTIL.ZIP . That is the version of the V6 file system routines I wrote to poke around on my Mini-Unix disk images while I was waiting to add RK's to my collection. They are pretty gross, but they mostly work. I actually used them to extract the source code for as and ld, and I then used that to write versions in C. Those should also be laying around on my hard disk, and if so, I will send them too. They were actually enough to build a Mini-Unix system with, if I remember correctly. Found my "as". Uploaded it as MXAS.ZIP . What it is is "as" re-written in C. MXLD.C is just that: ld.c from the Mini-Unix distribution (perhaps tweaked for MS-DOS: I don't recall). FULLLD.C is the same thing, for v6. As such, this stuff is obviously dependent on a v6 (or Mini-Unix) license. --- Jay R.
