Re: 11/73 into 11/03 chassis?

It's simple to convert the h9270 q18 (11/03) to q22. Just wire the additional address lines. It took me about an hour to do mine. Don't put an 11/03 in it after conversion. The added lines are not addresses on the 03 CPU. Joe > On Dec 10, 2015, at 4:26 AM, Jacob Ritorto

Re: Interfacing PDP 11/05 to VT 50

The current loop is actually "proper" . There are 3 parts to current loop 1) transmitter (switch) 2) receiver (opto coupler in dec stuff) 3) current source You will have problems if things don't match. An active transmitter has to connect to a passive receiver. Passive transmitter to active

Re: Common Maxtor MFM drive failure mode -- any ideas?

There is a plastic bumper in the head/disk assembly that turns to goo. When the head retracts it hits the bumper and gets stuck in the goo. The goo will eventually win. The head will no longer load. I can't say For sure this is your disk problem but it was a verry common Maxtor failure. Joe >

There's a surplus place here in Orlando that has a bin full of dec style handles in white. Google skycraft surplus. Their web site doesn't do justice to the store. You never know what you will find. I got an 11/23 with dual rl02 there a few years back. It's Orlando's second favorite attraction
