DVS - Dover status device #242

Do we need/want it? Who has a DOVER (it was a laser printer, if I remember correctly) these days?

Only when we can emulate such a printer do we need the device.

I have a theory that the Dover was first connected to MC, and later moved to another building and made accessible through a MINITS box via Chaosnet.

This DVRDEV looks like it's from the MC era. "It run only on the MC machine; other machines use device MCDVR:" In addition to DVR: providing a status listing, it can also run as a Chaosnet service with a host of contact names: DVR, DOV, DVS, DOS, DVQ, and DOQ.

Some code was originally copied from XGPDEV.

I remember the Dover being connected to an Alto on the 3Mb/s Ethernet. I'm not sure how the Chaosnet world got to it but through a MINITS box makes seems likely.

larsbrinkhoff commented 6 years ago

Right, an Alto running a program called Spruce. So for my theory to make sense, that Alto would (only?) have been accessible from MC for a period.

The MINITS part of the theory comes from the fact that there is a file called MITS.S; DOVER 1 titled "DOVER server (CHAOS/PUP)".

@dabridgham, I have now scrutinized both the old IOELEV code and MINITS. It seems they both support gatewaying printing from Chaosnet to PUP on Ethernet.

The ContrAlto emulator is capable of running Spruce and generates PDFs.
