Thicknet/10base5 Test Segment: The Cable is In!

I was speaking of the gear used on the 3 Mbit. I don't recall the 10 Mbit stuff at all.... I have this vague memory that the 3 Mbit cutter also had a shoulder stop that prevented one going too deep.

6800 fig-FORTH?

by stephen.m.pereira.sr＠gmail.com

Hi folks, I know there's not much 6800 activity here, but I figure this would be worth a try. Has anyone here ever seen or ever had fig-FORTH for the 6800 working? I have a SWTPC replica system from Bob Applegate / Corsham Technologies, and I love it. It came with a complete 64K RAM, as well as the SWIBUG monitor, and the monitor code has been extended by Bob/Corsham to interface with an SD Card sub-system for floppy disk emulation. This provides the original terminal access to the machine with the simple system monitor, and also the FLEX OS for running programs. It is a blast to use. Recently, I took a look around and found the fig-FORTH listing as originally published back in 1979, and also a Source Forge site that holds an electronic copy: https://sourceforge.net/projects/asm...th_6800-stuff/ <https://sourceforge.net/projects/asm68c/files/fig-forth_6800-stuff/> I've managed to get the source code to assemble with a cross-assembler supplied by Bob/Corsham. It does not produce an exact copy of the original code, because the code uses the JMP instruction pretty much exclusively, and the assembler substitutes a relative BRA instruction sometimes. So my code ends up being several bytes shorter because of saving one byte each time a JMP is replaced by a BRA. That said, it appears to me that the code matches up with the original listing otherwise. So my problem is this: When I run the code on my system, fig-FORTH seems to sign on, and will accept input from the keyboard (double echos of each key typed) but it then does not proceed to interpret the command entered. The interesting thing I see by winding my way around in the code is that it has already properly performed a bunch of setup and produces the initial "Forth-68" sign on, and that has required it to already be using many of the Forth commands that were defined by machine language. This indicates to me that some of the command interpretation is working. The I/O from/to the terminal is by calls to the system monitor I/O routines, and that seems to be also working, despite the double echos of the typed characters. It just does not proceed to interpret what is typed in at all. Of course, I have no idea if this code ever worked properly, or if I am encountering early buggy code. So I'm looking to see if anyone else has ever seen the fig-FORTH working on a 6800 system? Any pointers to good working code? Thanks for listening! smp - - - Stephen Pereira Bedford, NH 03110 KB1SXE

Restoring a PC Server 500 P/390 - Progress

by dave.g4ugm＠gmail.com

Folks, Well I seem to be running around in circles. As it takes most of a weekend to back up the P390 because of various things, I decided there must be a quicker way. And there is! 1. Set up SD card in SCSI2SD as a single disk physical rather than split to match the config on the RAID array. I still have the same number of partitions but they are all on one LUN. 2. SD card can now all be seen by windows but as most partitions a HPFS I can't mount them but I can use MS's DISK2VHD to image the card. 3. Install OS/2 in a VirtualBox and I can now mount the HPFS partitions 4. ZIP up drives and FTP to NAS box. Both are on same gigabit LAN so its fast. So I can now back up the server in a morning. Just need to script it and test restore. Dave.

Its now copying stuff to my Buffalo NAS but as its 10Mbit LAN its not terribly fast. I think the NAS isn't very fast either. It looks like zipping up the files and FTPing the ZIP files might be the quickest way to go.

It's the original RAID controller which I am not using. If I plug it in it starts the disks in the RAID array which takes ages, and steals the hard disk BIOS vector which I need for the SCSI card that's running the system. I didn't want to remove it fully as I need to label the cables feeding it. One feeds the top drive bays, and the other the bottom so if I ever need to put it back it I need to know which is which. If I get some free time I will have a go at starting the disks in it and repairing the RAID array, and perhaps copy the disks that are installed.

Lot of DEC QBus gear available...

by lbickley＠bickleywest.com

With the demise of Weirdstuff, I decided to visit Outback Equipment in Gilroy this week. Jim Schuetz, formerly a partner at Weirdstuff is now the Business Development Manager at Outback. While there, I looked over the following DEC gear (includes several non-DEC QBus cards that I'm not listing - as I have no idea what they are). Here's the DEC gear available: PDP 11/23 Plus (BC) PDP 11/73A (BC) PDP 11/23 Plus (BE) marked "Bad" (3) QBus Zip Drive controllers (1) M8043 DLVJ1-M (formerly DLV11-J) (2) M8190 (AB) KDJ11 (1) M9081 (LF?) (1) M7551 (AH?) MSV11-QA (1) M8029 RXV21 There's more "stuff" that you can see from the pictures below. All the PDP-11 "boxes" and boards look to be good cosmetically. Photos here: https://photos.google.com/share/AF1QipMAvVBdhz20-z7l6W9JXhBB0k3ggw0HWveHctE… Jim would like to sell the above as a lot. His contact info is: jim at outbackequipment.com Phone: 408-886-3733 Cheers, Lyle -- 73 AF6WS Bickley Consulting West Inc. http://bickleywest.com "Black holes are where God is dividing by zero"

Fwd: Re: TRS-80 bits

by brain＠jbrain.com

Anyone live near this Hotel?? I am just getting home and am just now seeing this.? Evidently, this is a rescue attempt, but I don't have a bunch of detail as yet. Jim Hi Jim I sent the below email to Peter yesterday. Have not heard from him. It would be a pity if neither of you can arrange to get hold of this stuff. Can you maybe provide backup if Peter can't make it? W Hi Peter TRS-80 bits will be at the Watson Hotel. 440 57th Str. Hell's Kitchen, NY 10019. Fellow is called Marius Killian and he's there today and tomorrow (24th and 25th). Sorry about short notice but I only came home last night. Please make plan to pick up, or for hotel to hold for you. Let me know. W

C3253A HP Envizex P-Series

by carlojpisani＠gmail.com

(x11 terminal) C3253A HP Envizex P-Series Up for sale is a X-Terminal made by Hewlett Packard in 1995. Tested, in perfect working conditions!!! cpu: i960 @ 33Mhz (it's the fastest available on Envizex v1) ram: 48MB (builtin + 16+16+8, the first two sims need to be equal) rom: none (sorry, It doesn't have any font-rom, it loads fonts from tftp/NFS) vram: 2MB lan: 10Mbps BASET RJ45 (it also comes with an AUI port on the back) kb/mouse: common PS/2 (F12 is a special key, but Envizex works on common keyboards, HIL keyboards are also supported) Media: floppy 3.5",1.44MB Software included! It comes with all the documentation, configuration-scripts, and startup for Linux (sorry, I don't have HPUXv10.20/v11, I can't test/adapt scrips). The machine is perfectly working, it supports the X Display Manager Control Protocol (XDMCP), you just need to power on your hardwired terminal and be greeted with a login prompt. This purpose is easy to be accomplished on HP terminals, especially if you use NFS instead of tftpboot. HP-net-stations can boot using either Network File System or Trivial FTP, with NFS being the preferred method it's simpler. During the final phase of startup, the bootup screen disappears and the X station loads bin/modules.ld, which tells what can be optionally loaded (but not executed), and then starts the X session by executing the application that was specified by the user on config/autoexec.cfg It supports all of the following: XDM login VUE CDE Lite (its panel appears similar to the one you can see on HPUX) mwm (simple windows manager) twm (simple windows manager) If you see one of first three login screens in the above list, you just need to enter your login account and password. 80 euro + s/h located in Switzerland
