I picked up a users manual for this, but it doesn't have detailed service
information.
Anyone have a real service manual for these? Chuck Guzis mentioned that the 8" floppy
encoding
was GCR, the disks aren't readable with a normal FDC.

Does anyone have any info/pictures/specs/etc on digi-log terminals (with built-in acoustic
coupler)?
Thanks much!

I remember using one back in the day, and particularly how small the screen was.

Yes, I saw that one..I'm looking for any further info.
I've been trying to figure out the type of terminal I first used at the Rolling
Meadows Public Library in the mid 70's to dial into the local
HS district's hp2000 timeshare system...and this digi-log may be similar.
Thanks.

Did it have a screen? Most of those little portable ones used a
thermal print head instead of a video monitor.

It had a screen...built in acoustic coupler...a couple of rocker switches on the right
side top, near the coupler.
I have very fond memories of that terminal and would love to find out what it was and
maybe obtain one sometime.

Did we determine for certain it was not a digi-log?
Here's all the raster CRT terminals in the wiki:

No determination...the one picture I've seen looks like a possibility.... I'd
like to positively identify what the terminal was...and then
try to find one for my collection.
(that terminal was my first foray into computers...connecting to an hp2000 timeshared
system... Since I now run an emulated hp2000 system, it would
be amazing to have one of those old terminals to connect to my emulated system....a nice
full-circle).
I must admit, for the mid 70's, the rolling meadows public library was pretty ahead of
the game to have a public access computer terminal available.

That would be it. I'll have the user's manual on bitsavers later today.

Al,
Thanks for posting the manual...looks like that is the one!
A digi-log model 209.
Now to try and find one for my collection.

No surprise, memory says it was a standard 5" diagonal monochrome monitor.
A friend use it with a 9" CATV monitor and it was easier on the eyes.
The oddity of the time was things like monitors were not to be taken lightly
as the onlyt market for them was mostly monitors. All were 60hz/525 line
(here in the US) usually with 75 ohm RX170 input. Some used
raw video, Hsync, Vsync but were other wise the same (motorola and ball).

Right; I don't remember the details at the moment, but I have put the
images of an RDOS disk on our FTP server (/pub/cm/futuredata). One
contains the raw samples from my floppy reader board, the other the
decoded data.

I just finished scanning the installation manual, and the photo of the bottom of the
floppy box clearly shows a Micropolis disk controller board.
The Futuredata manuals I bought will be up later today.

You're miles ahead of where I started with the Futuredata. Lockheed
Martin sent about 5 8" floppies. No information whatsoever on what they
came from--the people who might have known, given Lockheed's project
setup, were long gone.
It wasn't until I actually decoded the format and filesystem that I
discovered the "FUTURE DATA" string in a couple of programs that my
memory kicked in and I could identify the system that produced them.
The project being developed used the 8086, IIRC.
If you're interested, I may be able to locate my work (probably done
about 10 years ago, so no promises) and shed a bit more light on things.
