Congratulations on a really worthwhile achievement, and thanks
Well, I put the VT52 back together, tightened all the bolts, plugged it

transformer hum but that's about it.
Hooked it up to my PDT11/150, booted up RT11 and the display is
perfectly crisp and clear. Ran space invaders to

Following up on the results of my searching around. The FANUC A860 reader
with A20B controller (the normal set up) has a 50 pin output port. There
is a device one can buy that receives the signal from the FANUC's 50-pin
port and converts to into 25-pin RS232. The device is called a behind the
I have a DS20E Alpha machine. It's pretty fully configured, with two 666
MHz CPUs, 4GB RAM and 4x10K SCSI drives. In other words, it's a real power

That's fantastic Maciej! I often buy from Farnell, so there is no issue with
getting those parts myself. When I have accumulated enough wants to warrant
an order I will get them.
