[Simh] "Raw" disk access

I see in the SIMH v4.0 User's Guide that Windows and Linux hosts can use raw (real, physical) disk drives. Is there any chance that that capability will show up for VMS hosts anytime soon? It would make it a lot easier to move entire disk file structures back and forth between my emulated

Re: [Simh] DEC VT emulators on MAME

Right. The 330 and 340 have a cover plate you can attach so that it looks nice and clean from behind. But it's a piece of plastic that just snaps in place. Many never had it on as you wanted access to the cables a bit more convenient, which matters more than looks for many. Johnny Richard

Thanks Dave, my little brain did manage to piece it together later, LOL. That's what I get for sorting threads by subject instead of by date :). I'm starting to add pages for terminal servers to the terminals wiki: -- "The

Re: [Simh] DECserver (terminal server) emulation?

Emulating a real server is probably harder. It all depends on what the goal is. If you emulate the server, you can run the server code on it, which means you get exactly what that code does -- bugs and all. If you implement LAT at the protocol level, it's an independent implementation with a

Re: [Simh] DECserver (terminal server) emulation?

Would it be easier to emulate a Dec server, or fix the Linux Decnet code? If you had LAT working well under Linux, then writing a Dec server would be a simple she'll script. Well, maybe not real simple to get all the details right, but not too hard. Sent from my Galaxy Tab® A Original

All of this talk reminds me -- I've got a DS200 in my basement that I don't need any more.  Does anybody want it?  Free for shipping from 47408. Apologies for the off-topic-ness since this is real hardware :) Brian On 04/11/2017 09:18

Richard, You weren't very clear identifying the objects of the "What are these?" question. I'll define all of the terms for clarity. DS200 - Digital DecServer 200, an old terminal server with 8x 25-pin RS232 serial ports with modem control DS300 - Digital DecServer 300, an later model
