Spring 1982 DECUS RSX Group 312 Collection
This collection has several sets of entries:
[312,11] through [312,20] - Various utilities from Richard
Kirkman. Most notable are M+ versions of OPA and the BRUDIR
program which gives, in ONE PASS, a very complete directory
of a BRU tape.
* DDT22 - A new release. Fixes some bugs, adds macros so you can
automatically execute a set of commands at a breakpoint.
The new version also supports the I and D space option of
RSX11M+ V2.
* DGTUNX - A general tape mover, read/write fixed record length
files, and has new ability to read UNIX TAR format tapes.
Note: the block factor may have to be changed to 1 for
this to work reliably. BIGTPC bouncing an image mode
copy off a virtual disk will do it...
* BIGTPC - My latest version, has image mode copy support for
moving around images of virtual disks. Also can copy
disk to disk in container files. Can create pseudo-FLX
tapes with disk images with block factors up to 72.
[312,330] - A sort package from Glen Hoffing. Looks like the
DEC SORT-11 but uses FCS, not RMS.
[312,320] is an earlier version.
[312,322] - Glenn Everhart's latest VE: driver. This is a rev
to VD: that will work on M or M+ (V3.2 or V4 of M, or
V1 or V2 of M+) which can be built to allow multiple
files or devices or mixtures of them to logically be
combined onto a single disk. Current source supports
up to 8 files or device areas (by filename or by LBN
and length) per virtual disk. The name is changed to
VE: to permit it to coexist with the older VD: type disks.
This allows you to have NONCONTIGUOUS VIRTUAL DISKS,
or to pretend that 5 or 6 of your old RL01's and
RK05's are really a big disk. Biggest contiguous space
will still be the size of the real largest contiguous
space (the driver invents some phony "bad" blocks),
but your total volume will be able to be large.
[312,327] is an extra copy.
[312,331] - A PACMAN by Glen Hoffing. This game works on VT100's
and does NOT require advanced video. Looks very like
the arcade game PACMAN. Control C erases the screen.
(It works OK on VAX too!) Several versions of the
source are on the tape; the highest UIC is the latest
and presumably best debugged. Earlier versions will allow
higher scores supposedly and are supplied for the
ego gratification of those who want to amaze their friends
by appearing good at the game. Uses the 4,8,6, and 2 keys
for controlling PACMAN's direction. The game even includes
the fruits. Source is in RATFOR which may make it easy
to convert to C.
[312,321] and [312,325] are earlier versions.
