Sorry, I thought yesterday I answered your post with the picture I took while cleaning it up. But here it is.
The only info I have are these:
DoubleTime-16™ Accelerator Features: • easy installation • math coprocessor support
• 16 MHz 68000 chip
• twice the speed of an SE
• 100 % compatible
• port for large screen monitor
So the pinout would be nice to know how to attach a external large screen monitor.
