[HECnet] RT-11 on a PDP-11/10

Hi all. Update have an 11/10, that was recently powered on again for the first time in I don't know when. After some fiddling with the RX01 disks, we put an RL11 and an RL02 on it. Lots of space, I know. :-) Also, we have RT-11 running on it. And for fun, we wanted to run the original Tetris. But here is the catch - Tetris is using some instructions that the 11/10 don't have. (I would guess EIS stuff.) Do anyone know if there is some software emulation of these instructions that can be added to RT-11 in order to be able to run such programs? RT-11 V5.5 by the way, if anyone wants to know. And no, I am not sitting by the machine, or trying to play with it personally. It's other people at Update. But an 11/10 is cute. And we did boot the RL02 on Magica (11/70) to check that there is nothing wrong with the binary, and it runs fine on that large machine. Johnny
