To create a logical disk:
create file.dsk/alloc:494. (rx01 size, RX02=988, rx50=800)
mount ld0 file.dsk dk (mount as LD0, assign ld0 dk)
init/bad/noq dk: (impose a directory structure)
now proceed to use ld0 as you would any other device...
If you already have a disk image with stuff in it..
mount ld0 image.dsk dk (mount existing file as ld0,
assign ld0 dk)
dir (get a directory)
Again, just use it as you would any other disk volume.

Seems there is some confusion here. TOPS-10 and TOPS-20 were DEC
operating systems for the 36-bit DEC-10 and DEC-20 mainframes, circa
late 60's (DEC-10) thru late 70's (DEC-20). TOPS dies when the VAX came
out, thought there are vestiges left in VMS.
The TOPS networking cards were essentially Appletalk cards for PCs. It
was a low speed network using a Z80 SIO (or SCC?) serial USART and
RS-422 drivers instead of RS-232. IIRC the speed was around
230Kbits/second (I have one in the back of a closet, haven't looked at
it for a while). No relation to the TOPS operating system at all.

No national 8x300 was the second source. ;)
SMS was the creator. An 8bitter design for DSP at better than 6mhz
throughput. Very non-Von machine with very seperate instruction and
data paths.

Yep.

Allison -
IIRC, you were about to write some code to hook up one of these
parallel-IDE HD kits to a CP/M machine with an EPP. Could this be made into
a more generic project to allow file transfer over any CP/M parallel port?
I for one would like to be able to transfer CP/M files from a variety of old
systems to a portable IDE drive which could also be read on my PC in order
to make archival copies of software for CD-ROMs. And I think there would be
other interested parties as well.
On another matter, thanks for the RAM 17 manual. And I'm sending you 2
unopened boxes of Dysan 10-hole hard sectored disks for your N*, plus
another dozen of used, but perhaps not as used as some of yours, N* disks.

Here's a question: what _obsolete_ computer would you choose for this
miracle machine, assuming you have unlimited power?
My choice would have to be an IBM PC just to vent..

Hello, all:
While in the process of examining my old P-E and R-E magazines, I came
across an ad for MITS from mid-1974. The ad was for a 4-channel digital
handheld memory scope (model MS416) for $189. It seems to be a simple
digital logic analyzer.
Does any one have info on this? If anyone's interested, I'll post the
picture.

On *some* backplanes, there is no difference. A dual-high board could
be plugged into the CD side just was successfully as in the AB side.
In other backplanes, the AB side is the Qbus side, and the CD side is
set to connect adjacent boards so that they can communicate (such as
the VSV11, the RLV11, and the 11/83 and its PMI memory).
In yet other backplanes, you find that it is Qbus in the AB slots and
CD bus in the CD slots for part of the backplane (BA23 = three slots,
BA123 = 4 slots) and then it switches to Qbus in both the AB and the
CD sides.
Bottom line -- make sure you know what backplane you are plugging
boards into before you do so. Also, make sure that quad-high options
which can plug into both Q/CD and Q/Q have the CD jumpers on the board
set correctly.

Well it (and a lot of Carlos' other works are available on CD). I used to
use this sort of music to program to, but I'm more into the original
arrangements for programming now (not that I do a lot at the moment, but
there is this nice program I want to write for work that could end up
written in BCPL for old time's sake :-)

Robert Duvall said it best in Apocalypse Now: "I love the smell of

In this case, victory over every bug-ridden PC ever made.
