Message text written by INTERNET:classiccmp@u.washington.edu >Does anyone have a Commodore Plus/4 video cable for sale or trade?< The 8-pin cable for the Plus/4 is exactly the same as the 8-pin cable for the (more common) Commodore 64 or 128. And, a 5-pin cable made for the 64 (the early models had a 5-pin port) will also work on a Plus/4. In fact, I think most home computer manufacturers (Atari, TI) used 5-pin cables with the composite, sound and ground on the same pins, so you could try one of those if you have one sitting around. Finally, if you want to hack one together, I can provide the pinout. Gil Parrish 107765.1161(a)compuserve.com

Some of that stuff does go really cheap but not all. I do plan to post a big list of the stuff I was selling at the garage sale and the prices should be very reasonable (cheap). You are right in that the G sale stuff isn't rare. I had 3 Apple II+, an Apple IIc, C-64, Piles of C-64 power supplies and cables, joysticks, Atari 2600 consoles and games. Only thing is that they need to be shipped which can be more than the price sometimes. I did manage to give away 4 dead C-64s and a 1541 to a guy who works on them. Give me a month or so.

Info needed: VAXStation 3520 & others...

Info needed: VAXStation 3520 & others...

by IVIE＠cc.usu.edu

> 1st: (the biggie) VAXStation 3520. 'Cube' configuration, apparently 4 > processors Four processors would make it a 3540... > , 64meg of ram, a TK70 and controller, one board that appears to > be the interface between the processor bus and the three Q-bus slots in > the chassis, How much stuff is on the QBus adapter board? There were two versions: FTAM supports only the TK70 controller (is you TK70 attached to QBus or to SCSI?) and FQAM supports any random QBus module. FTAM is a simple module containing only a few chips; FBIC (interface to the backplane) and CQBIC (CVAX -> QBus adapter) being the only really big ones. I believe there was also a clock generator chip, but not much else. FQAM is chuck full o' goodness. It his a prom-based microcode machine to run the module and lots and lots of PALs. > and a board on the processor bus marked "I/O Module" with two > 50 pin headers on it. The connector which goes out the side of the backplane is SCSI. Although DEC used the DSSI chip on this module, they only supported SCSI; the DSSI chip is capable of doing both. The connector which comes out the front of the backplane goes to a distribution panel which provides: - Four serial ports (console/printer, modem, mouse, keyboard) - Ethernet (AUI and BNC) - Diagnostic code display (one 7-segment LED) Unfortunately, I don't know the pinout of the cable; I don't have a printset for the 3520. > There also appears to be a space for what looks like it would have been a > three board video sub-system (which has been removed). Three boards is correct.

(and no place to plug in > a terminal!) The terminal plugs into the distribution panel which plugs into the I/O module.

(fwd) Model 4 video problems

by bluesky6＠ix.netcom.com

Can any expert out there help me with this? Thanks! In comp.sys.tandy, bluesky6(a)ix.netcom.com (Benedict Chong) wrote: %I just got a Model 4.

HHCs

by bwit＠pobox.com

I must've fell off the list last week when the Internet went haywire and I've just resubscribed. From the tone of this message it would seem that the HHC deal fell thru. Would someone mind bringing me up to date?

I have retained the list. There were a total of 53 interested persons, so hopefully there will be enough for everyone. If there are extras then maybe we'll just hold a lottery.

VIC-20 Kernel Project

by 107765.1161＠compuserve.com

Message text written by "Richard A. Cini, Jr." > For the last two years, I have been working on making a recompilable version of the VIC-20 Kernel ROM.< OK, I'm not afraid to ask the amateur question: Why? I'd love to see someone with good programming skills write some sophisticated software for the VIC-20, likely requiring at least a 16K expander or something. If your project will help lead to that, I'm all for it. Gil Parrish 107765.1161(a)compuserve.com

CLASSICCMP digest 124

by allisonp＠world.std.com

Bruse Lane queried: <The VS2000 is the little square 'cube,' is it not? If so, I have a pair. <was planning on using one for a disk formatter. Yep the 1cuft vax., Has MFM disk interface for hds and 5.25" 1.2meg floppies and on the mainboard there is a 50 pin connector for SCSI. Plug a cable with 50pin berg into it and bring it out the bottom. The only SCSI device it will boot is TZK50 (TK50 with SCSI adaptor). However if you can get ultrix or VMS on a disk it both can use the SCSI to access otehr devices other tha boot. Also the printer port(9pin) if you pull pin 9to ground and boot it becomes the console for a terminal. FYI the disks that work with the vs2000 are st225/20meg HH, st251/40meg, RD52(quantum q540 31mb), RD53(micropolus 1325/71meg) and RD54(maxtor2190/150meg). Other drives with the same geometry can be used if you want to use it with media the rom knows. <??? How so? I've not worked enough with the stuff to guess at that one. Boot the OS, build a single user system on disk and use that to build a bootable tape. <A! That's IT!! Yes, I can do this! I can build Ultrix onto one of my <3100/M38's then, and use it for netbooting the VAXStation! Yes you can as most of the vaxen will mop boot if the NI is there. <Allison, if you were within range, you'd get a big hug! I even have an <honest-to-DEC RRD42 SCSI CD drive just waiting to be used. <If you could outline the steps for me, so I can have a printout to refer <to, I'd appreciate it. Thanks again! Wish I could. I know the outline only and that the capability is there. <BTW, can I also do the remote boot with OpenVMS? I picked up a Ver. 6.2 <distribution kit while I was in the Bay Area. Yes, and depending on the license you have with it(must have) you can also cluster them using NI. The cluster host can be any vaxen, the higest performing one you have is the logical choice. The alternate is booting as a diskless workstation or remote boot(localdisk for swapfiles). Vs2000s were commonly used as workstations with local swapdisks (rd52s or rd31s) or as decwindows terminals. FYI: vms without the license pak for it is marginally useful. Brief explanation of MOP boot. This is a DEC protocal that goes back to PDP-11s(they used serial lines for this!) and it was Maintenance Operations Protocal. It allowed one system to push code into another. It's protocal is fairly simple, the boot requestor puts a message on the NI that says BOOT ME and it's Eithernet hardware ID. The host is tasked with recognizing the address and feeding back the correct file usually a boot loader. The boot loader is more sophisticated and will then respond back saying ok lets use a better protocal and it then loads the one of three things, another bigger loader, VMSboot or untrixboot. After that point the protocal is usually either IP or DECnet though user selected protocals are possible. The actual application loaded is up the the designer/user and examples I've worked with were DIAGS, PrintServer (lps40/20/32), DECwindows, VMSworkstation remote boot and VMS cluster. Doing this on unix systems means you must have a operating host with networking running. The boot process from the requestor is the same but the host must have a daemon to handle the booting process. USually there are config files to manage this. Allison

Is there a DECsystem-ten emulator for free/shareware?

by dseagrav＠bsdserver.tek-star.net

I heard there's 3 DEC-10 emulators, but all are commercial products (And therefore pretty expensive!). Are there any freeware or shareware ones?
