Guess what ZEMU identifies itself as? :-) The only game that I know of that cares are BEYOND ZORK, and it works nice if you have a VT220 or newer, download the soft font I designed, and then just play on... If someone have a VT525, they could even test color...

True in a way. The game was split up because it was too large. It was also reimplemented because MDL didn't exist for home computers, and that language in it self required too much resources and in general required too much of the computer. A big breakthrough was when they decided, and managed to pull off the Z-machine. You can all read about this at the http://www.csd.uwo.ca/Infocom/ website. Lots of articles and interviews with the original implementors. >> And ZEMU *should* work on RT-11. I have a suspicion that maybe one or >> two routines might be missing.

Implementing screen-handling for an RT-11 version of > Frotz shouldn't be very hard. In your dreams. :-) First of all, I suspect that dumb Frotz still would get into major problems with the small address space of a PDP-11. Second, Frotz makes some assumptions about file handling that just isn't true on all non-Unix systems. And screen handling is a story of it's own. But people are welcome to try. Heck, I can even offer an RSX machine if someone wants to take a shot at it there, with an ANSI C compiler... It would be interesting to watch, at least. People often just don't understand how much Unix-specific stuff is going on in the code.

Zemu

by henk.gooijen＠oce.com

I corrected ZIO and ZMEM, and they compile without errors, as expected. Then I removed the "LIBRARY SYSTEM.MLB" line in ZRT.MAC ... I get 65 errors, starting with MCALL undefines. Is it possible that Megan can change this to support the RT11 version that comes with SIMH (v5.3) ? (The changes required in ZIO and ZMEM are simple). - Henk. > -----Original Message----- > From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Johnny Billquist > Sent: dinsdag 25 april 2006 19:31 > To: cctalk at classiccmp.org > Subject: RE: Zemu > > "Gooijen, Henk" <henk.gooijen at oce.com> wrote: > > > OK, thanks Johnny. > > I have a day off, but that's for working in the garden. > > This evening (when my back is hurting) I will change the > > hex values to octal. > > That should fix the first problem, and that should be easy... > > > If somebody could make the SYSTEM.MLB avalilable in a .zip > file, would that > be sufficient to solve the second issue ? > > Might.

FA (Sheepishly promoting) Mark-8

by grooveomatic＠gmail.com

Hello all! It's been a long time since I've stopped by to post... I monitor CCTalk every now and then, but haven't posted in a long time. I just thought I might send a quick message to say that my poor Mark-8 is headed to the great ebay in the sky. I am too poor to keep him any longer and I know somebody will end up enjoying it more than I'm able to at the moment. 8799174918 on ebay if anyone might be interested. I apologize hugely in advance if this is verboten; I didn't know who to ask if it was OK! The old FAQ seemed to mention that it was OK, but the old FAQ also said that it was not to be looked at. :) Bryan Blackburn has helped me out a lot over the past few days - thank you! :) Best regards, Andy

teledisk files

by chd_1＠nktelco.net

How do I convert a teledisk image to something useful to me without having the hardware? I have some images of decus DM-101 that are in teledisk format. I want to get the contents onto my PDP-8/e. I understand that teledisk saves a lot of meta-data about the disk image... but I don't think I need that. All I want is the data. decus DM-101 on paper tape would be fine with me... an EPIC tape would be much better... and a simh disk image would be the greatest... -chuck

And, if I'm not mistaken, I believe it was originally developed on this machine (though I could be off on this fact). I actually visited the famed 9th floor of 545 Tech. Square at MIT way back in the early 80s and saw the beast. (Still have my MDL programming manual around too...) </Nitpick> --Eric F.

Cyberentics ASP??

by rigdonj＠cfl.rr.com

I went scrounging this weekend and one of the things that I found was a Cyberentics ASP. It's a chrome and black rack mount chassis with dual 2GHz AMD Athlon MP processors, 256 Mb of DDR memory, a DriveOnModule that plugs into the IDE port and emulates a 32Mb disk drive (has linux installed), TWO Symbios LVD/SE SCSI cards and two large IBM Ultrim LTO tape drives. No other drives installed (or even a place to mount them) except the two tape drives and the Drive On Module. NO video card installed but it has two LCD displays on the front panel. What have I got here? Joe

anyone have a terminal server? - Xyplex, Xylogics, and DEC history

Xyplex was founded by 3 ex-DECies as a terminal server company before Digital had established the LAN DECserver and LAT. One of the founders was the author of the CTERM protocol and witnessed the debacle of the Mercury terminal server. (but I digress) Their initial designs used proprietary LAN media and protocols. Their later products used more commodized technology of the times. I don't know the 'rep of their product. But the company was very successful for awhile but was later acquired by Raetheon and then traded around the aerospace/computer industry before disappearing. Xylogics had been in business for many years doing various computer related things, including peripherals and disk drives, before acquiring the rights to the "Annex" product line from a third party. The products were based on a proprietary Unix kernel and spoke telnet, PPP, and LAT and other things. I was instrumental in getting them to implement RADIUS. In 1996 they were accquired by Bay Networks where they continued to produce terminal server products (5399 blade system) until the merger with Nortel. I'm not sure what happened to the IPR of the Annex, I believe it was sold to another company. The former DEC terminal server line was spun off to Cabletron, and the remains live in Enterasys. I attempted to assertain whom owns the rights to LAT last year (as a reference in RFC 4005 Diameter NAS Application) and got a murky answer. The last vendor selling code (Meridian) went out-of-business a few years back. Dave Mitton.
