[cctalk] Re: Trouble with DEQNA adapter

Collision detect check failure is a warning, not a send failure -- the message is misleading There are several possible causes. 1. The transceiver predates SQE check, it doesn't implement the signal. If so, turn off the message, you're fine. 2. The transceiver can do SQE but it's turned off.

Collision check test is, if I remember right, a feature that wasn't in the Ethernet spec but got added by IEEE 802.3. So old transceivers may not have it. In spite of what the event says, it's not a send failure because the SQE test signal occurs right after the packet is finished. If you hav

Earlier there was a question about MSCP disk sizes. I did some checking. RSTS understands all the devices known by name in SIMH, including the "giant" RF73. As of the "big disk" support, which is in V10.1 and I think a few earlier versions, it can handle something that big. It draws the line

Another way to use them is to switch a series resistor out of the power supply input after a few seconds; that is good for capacitor-input filters where the inrush current is otherwise very high. The 5 second delay may be just that; it seems a bit short for the pre-heat delay. paul >

Just below the photos is a link to "a detailed PDF" -- which is indeed quite detailed, including a list of all the pieces, all the spare FlipChip boards, all the paper tapes and documents. Looks like quite a find; if I were at all a PDP-8 person I'd be seriously interested. paul > On
