Hmmm. Not that I recall.

I have plans to make a bracketless XTIDE card that has a 2mm notebook drive header on it so I can use an SD card to notebook adapter I have. It’ll fit in the unused slot and let the AST SixPakPlus continue to hang the parallel and game port off the bracket in the back.

MTS
There have been a few references to MTS over the past couple of months that led me to suspect people are running it under Hercules. I did some poking around a while back and managed to find some tape images (bitsaver, I think), and did some cursory reading of the release notes. I think there might be enough there to IPL and perform a basic installation, but what immediately caught my attention was the mention that sites had to purchase ASMH from IBM, which leads me to believe the public distributions don't contain an assembler. I cut my teeth on *real* computers on the U of Alberta's Amdahl running MTS, and I can't possibly imagine using it without an assembler. So my first question is: is anyone running MTS under Hercules from these public images? And if yes, question 2 is: which languages are included? One of the main reasons I would like to get MTS running would be to play around with the scheduler code. I remember some changes that were introduced circa 1981 that - I thought - destroyed the interactive response time of the system. E.g. APL went from being a joy to practically un-usable, IMO.

Re: MTS
The UMich guys have made available images of tapes from many MTS releases. Not all releases are complete. They've also provided a built system of D6.0 (1986? -87?) with all the further changes it was running just before shutdown in the 90s. (No tape images for this version yet.) You may want to look at: http://archive.michigan-terminal-system.org/ ASMH is a licensed program product, so they can't make it available. MTS used a fairly heavily modified version of it. A lot of other languages are included, though. There's a list on the above web site somewhere of the license status of many things. Source is included in the tapes. If the SHOW bits to which you refer were shared amongst the consortium, and predate the release of D6.0, they're quite likely in there somewhere. IIRC the copy of the MTS manuals on bitsavers were actually freshly generated in the last few years, so the thing might be referenced there. De

As I understand the history, RMS created ^R mode in TECO ("real-time
editing", for the uninitiated), and lots of people began creating TECO
init files that defined various key bindings for favored commands. RMS
then collected everyone's init files, put the ones with consensus into
a default configuration, and published the result as EMACS. The things
that didn't make it into the default key bindings went into libraries.

IVORY was an alternative to PURIFY. PURIFY stripped out comments and
white space; IVORY stripped comments, but left white space alone. It
could also combine PURIFYed and IVORYed compressed output into a library.
(I used to have my own version of EMACS, with different key bindings for
the kinds of things I needed to do often and functions from some of the
other libraries built into the main library instead. That got lost
when I parted ways with XKL; I still miss it, years later.)

Re: OT: Slow booting, was re: Booting an IBM MP 3000 S/390 System
Just a follow-up on the problem of a Supermicro P6DGE taking forever to boot up. I tried several versions of the BIOS with pretty much the same result. Since each reset the configuration (CMOS) memory, there was little issue of an overlooked setting contributing to the slow boot. I tested the "fast boot" in both enabled and disabled settings and found that the POST took almost exactly the same time--the only difference was that the memory check "odometer" didn't display in the "fast boot" setting. Could it be that the presence of ECC registered SDRAM requires that every memory location get written before boot-up can proceed? There's 2GB of the stuff, so that could be the difference. --Chuck

Ah ha! Pulling the dead battery has brought the Blit back to life. It passes self-tests and now is screaming "WAITING FOR KEYBOARD STATUS". Back to the search for a compatible keyboard. Two, really, since I also have a 730+ that needs one. -ethan

Re: SCSI Tape to TAP utility
Thanks Jay! Marc From: Jay Jaeger The link below is to a Google Drive folder with three files that I will leave up for a while: awstape.c - Read a SCSI tape, output in AWS format (Linux) awstoraw.c - Read an AWS file, output a raw byte stream awstosimh.c - Read an AWS file, output a SimH https://drive.google.com/folderview?id=0B2v4WRwISEQRfi1TWnlKU1hqUXphWVhpZ1FK OGFoVjRPVnppX1F2aUMwTUw0QkxSNEsyMjg&usp=sharing They are anything but elegant, but have gotten the job done for me.

Re: MTS
Dennis is correct, the MTS source and binary tapes were released to the public a few years back and the URL he quotes is the hub for everything MTS. If you want to spin up an instance yourself from scratch, I wrote a little tutorial some time ago that will distill down the installation documentation for you, and notes a few potential snags: http://wildflower.diablonet.net/~scaron/herculesmts.html It's actually pretty easy to install and run MTS from scratch, in rather stark contrast to many operating systems that ran on the 360/370 platform. There are a wide variety of assemblers and compilers included; here's an overview; just a few of them are broken (Pascal, C) but most run: http://archive.michigan-terminal-system.org/discussions/programming-languages-available-under-mts Have fun! MTS runs great on Hercules. I have an instance running pretty much continuously on one of my servers and I'm always on there playing around with old languages.

And speaking of ALGOL
One could always implement a KDF9 emulator and then port Randall and Russell code (from the book). And r.e. ALGOL68, Peter Hibbard had some sort of ALGOL68 system working on the PDP11s at CMU I believe.
Re: PDP-12 Restoration at the RICM
We found a shorted diode in one of the rectifiers in the +/-42VDC supply in the VR14 that was causing the main fuse to blow. The donor of the PDP-12 gave us a spare so that was an easy fix. We reinstalled the VR14 in the PDP-12 and ran the display diags. The VR14 display actually works! We found a open trimpot for the gain on the vertical flip-chip. We swapped the horizontal and vertical flip-chips, adjusted the gain trimpot, removed the flip-chip, and added a fixed resistor with the same value for now. The display when running the diags looks very nice and crisp. We booted LAP6-DIAL and could display a listing of the files on the tape on the VR14 monitor. After about 20 minutes of running nicely, the TC12 went back into the mode where it could not find blocks. Oh well, more debugging to do. -- Michael Thompson

Re: Booting an IBM MP 3000 S/390 System
z/OS is a licensed product from IBM (read $$$'s involved). Generally you can't run anything newer than MVS 3.8j on Hercules. See the Hercules website (http://www.hercules-390.eu). It has links to other sites where you can get various OS's and other programs that can be legally run. Note that there is a "turnkey" system for MVS 3.8j that is set up for Hercules that has an ISPF-like clone. I have that set up to run on my Mac. I also have the VM/370 "sixpack" installed as well when I want to run VM/370. The version of z/OS installed on my MP3000 does have ISPF (along with lots of other program products) installed.

The compiler ran on TOP-10 and generated code that would run on C.MMP (a 16-way shared memory multiprocessor PDP-11) running Hydra (a very cool capabilities based OS). I still have my copy of the "Hydra Songbook" which is the manual that describes all of the K-calls (kernel calls) and the basic application environment. TTFN - Guy

A piece of engineering much advanced for its time. Did DEC ever produce a machine that ate Algol as its native programming language? --Chuck
