DigiBarn Systems: Digital Group System

Here are the details in the photo starting at the very top left with that wide thin box:
Phi deck - 4 independent phillips cassette based storage
tiny box is digital clock

Next row, left side with paper sticking out:
tdg dot matrix printer-parallel port interfaced
Dual 8 inch floppy disc
tdg 64 x 16 B&W monitor

Next row of 2 large identical boxes:
main consoles - the original tdg bus would not hold all of the boards they offered and still have
a large enough power supply so I split the system between 2 main boxes. One held 2 huge brute force power supplies and some audio boards for their votrax talking board and the other had 2 bus boards wired together to take the maximum 64K for static RAM and all the I/O,control and other option boards. Ran amazingly glitch free. They later came out with more compact and higher density dynamic RAM as well as more efficient switching power supplies. (It was very difficult to talk them into selling me just a second empty console box as they were always in short supply.)

Final bottom row:
tdg keyboard
dual joysticks

the contraption on the left with the manuals is a miniature MITE teletypewriter for impact printing and making "carbon copies"

The large terminal that sat just to the right as shown in the right hand photo was a Compucolor ISC 1500 color terminal that communicated serially with the system and rendered color pictures. You can just make out a RWB American flag on the screen. I actually used this terminal to display slow scan images that were acquired with the tdg Ham/RTTY board - way off to the left in the first photo you can see some transmitting equipment that I used for RTTY short wave communications.
All of this is now off the shelf appliance stuff but 30 years ago this was mind blowing technology!

tdg offered a huge library of really nice software as you can see from all of the manuals in both photos. One novel mod on this particular system was the ability to boot up from a number of different eproms into 6 or 7 different OP-systems from the CPM standard of the day to some really strange ones the tdg promoted.
