UNIBUS FTGH: EMM / CMU MICRORAM memories &

by tshoppa＠wmata.com

The Microram was a multipurpose solid state memory chassis sold by EMM (Electronic Memories and Magnetics) with what we called later in the 1970's a "personality board" that plugged it into each different CPU's backplane. They sold a similar system (maybe even plug compatible at some level) with core planes under "Micromemory" brand name. I see we already have a "emm" directory in bitsavers with docs about some of their core products.

FTGH: EMM / CMU MICRORAM UNIBUS memories & docs

by fritzm＠fritzm.org

Okay, I'm trying to beat back the hoard in my basement before the rainy season starts here in CA: I have a couple of NMOS static RAM UNIBUS address spaces that I picked up from CMU sometime back in the mid-'80s once when they were cleaning house. I've been hauling these around for 30+ years, thinking I would use them with the '11/45 that I picked up at the same time, but as previously discussed here I have a much more practical MS11-L working in that system now. So, I'd be more than happy to pass these one to somebody else who could put them to good use? There are two; they are 5U 19" rack chassis with integrated power supplies and fans. These are card cages with slots for 5 11"x15" cards plugging, into a PCB backplane (big, heavy!) Each chassis contains four fully-populated MICRORAM 3400N memory cards (at 32K words x 18 bits each, each chassis is a full UNIBUS address space); each of the memory cards caries 144 x socketed 4402ACC, with 1977 date codes. Each chassis also has a fifth card, a custom UNIBUS interface card that was developed at CMU, which takes the place of the self-test card in the original units. The units are marked S/N 100001 and 100002, P/N 929331-009A. They are in good shape, but dusty, and with some corrosion evident on the chassis. Have not seen power in several decades, so the power supplies probably need a going over... I also have full documentation (including schematics), and a folder of schematics and some hand-drawn notes for the CMU interface cards. I have dups of the EMM documentation, so could send it to Al if he is interested? Anybody out there interested? I am in Oakland, CA. It would be best to pick these up in person, because they'd probably be $$$ to ship. cheers, --FritzM.

Partial success (SIMH TSS/8), new problem has me stumped

by charlesmorris800＠centurytel.net

I finally managed to get TSS/8 running under SIMH V4... console on the laptop, a time-sharing line (TTIX port 23) on an ADM-3A (much quieter while debugging) :) The interface is the Volpe current-loop to USB board, a small freeware program "COM By TCP" to allow a TCP port (USB is COM4, TCP is 127.0.0.1 port 23). So far so good. But I am having connection problems with the data coming >from SIMH to the terminal. At 110 baud I only get a few characters before the serial-TCP program hangs with this write-timeout message: 22:24:11: Socket connected to 127.0.0.1:23 22:24:11: SOCK: Unable to write on COM. The port is CLOSED.. <-- this is because I didn't "Get COM" first. 22:24:13: COM4 correctly opened! 22:24:24: System.TimeoutException: The write timed out. at System.IO.Ports.SerialStream.Write(Byte[] array, Int32 offset, Int32 count, Int32 timeout) at System.IO.Ports.SerialPort.Write(Byte[] buffer, Int32 offset, Int32 count) at COMbyTCP.Form.sockClient_dataRecived(Byte[] buffer, Int32 bytesRecived) I tried at 1200 baud and the same problem occurs, I can just get more characters before the terminal screen freezes. Nothing's locked up except the downstream SIMH data (i.e. I can hit Return on the terminal and the TSS/8 dot prompt reappears). It is repeatable regardless of what I am trying to do on the terminal. Only very small outputs come through in their entirety without this error message. I don't think it's the current-loop board, which has an onboard micro fast enough to translate Baudot on the fly. And the receive light stops flickering at the same time the write timeout message pops up. Does anyone know how I can extend the timeout parameter... is this a Windows networking problem, or something flaky in the freeware serial-TCP program? thanks Charles --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Connecting SIMH to teletype via USB

by charlesmorris800＠centurytel.net

I could use a hint... I have a USB to current-loop (Volpe) interface board, and Windows 7 on my laptop does recognize it as COM4 at 110 baud. So far so good. No problem hooking it up to my ASR-33 Teletype. Now I'd really like to figure out how to set SIMH to use the 33 as the console, so the TTY will be attached to the virtual PDP-8. I do have OS/8 and TSS/8 running on SIMH with the laptop as console. Just don't know how to make it "talk" to the USB serial port instead. Anything that starts with "set console..." gives a "no settable parameters" error. Thanks for any hints. -Charles --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Connecting SIMH to teletype via USB

by charlesmorris800＠centurytel.net

I got ahead of myself a little bit... forgot I still couldn't connect a serial port to SIMH. Turns out my version of SIMH 3.08 was from 2008 or so... I just downloaded the latest version 4 from GitHub and sure enough it does accept SET CONSOLE SERIAL. Now I just have to figure out the port name since it doesn't like COM4: But I'm almost there :) -----Original Message----- From: Charles Sent: Friday, September 13, 2019 6:46 PM To: J. David Bryan ; cctalk digest Subject: Re: Connecting SIMH to teletype via USB Update: got my SIMH (set console telnet:23) talking to PuTTY in another window, via Telnet 127.0.0.1:23. So it is possible ;) Now it's time to hook up the actual TTY to the USB-current loop card and see what's what! -----Original Message----- From: J.

Section 3.14, "Console Options" of the "SIMH Users' Guide V4.0" suggests that: set console serial=com4;110-8n2 ...should work (though you might need "7e2" or "7o2" instead, depending on how your Teletype is set up). > Anything that starts with "set console..." gives a "no settable > parameters" error. Does the above also give this error? -- Dave --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
