1) Edit your copies of the VM01.PA and ID01.PA files to ensure that = the=20 line which reads

/SYS=3D1

is commented out. The "/" = is the=20 comment character in PAL8, so if the line appears as you see it above = then it is=20 already commented out. If it appears this = way:

SYS=3D1

then=20 you need to add the slash.

2) Create a copy of the OS8V3Q system = disk and=20 use FLX8 to copy the ID01.PA and VM01.PA files to it. = Unfortunately there=20 isn't enough room on the original OS8v3Q diskette, so we'll have to = delete some=20 files that we won't be using. [If you're a brave soul you can = actually do=20 this step under OS/8 using
TECO, but for now there's no need to make = our=20 lives more complicated.]

[The=20 strange looking devices, (6775), (6776), X, J4, etc are really the = VMA0..VMA3=20 and IDA0..IDA3 devices. The problem is that the standard OS/8 V3Q = RESORC=20 program doesn't know about these device types and can't print them=20 correctly. Worse (much worse!) OS/8 PIP doesn't recognize the VM01 = or ID01=20 devices either, and so we cannot use the ZERO command to initialize an = empty=20 file system. Fortunately this is a common problem and it was well=20 documented by DEC how to patch PIP to add additional devices. = That's what=20 we'll do next.]
