Hi-- I was wondering, is all blank papertape media interchangeable? I know that it can be made of paper or mylar, and that it comes fanfolded and on spools, but are there variations that would block interoperability, like varying widths? In particular, I'm wondering if any one can tell me if the tape offered up on ebay at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2519056219&category=11805 will work in my friden flex-o-writer sps... (for that matter, if anyone here can help me find sps user and repair manuals, that'd be lovely... I'd like to know the pinouts on the i/o ports on the side, and I need to repair one of the carriage return straps...) --thanks in advance --akb

Need byte-splitter utility

by kyrrin＠bluefeathertech.com

Hi, gang, I've got a single EPROM file that I need to split into separate odd-byte/even-byte files for programming into two separate (smaller) EPROMs. I'm not able to figure out how to make the Unisite programmer do this, so I'm thinking a DOS or Windoze based splitting utility will do the trick. Here's the problem; I've searched all over Google, and can't find anything that'll work. Any ideas? Thanks much. -=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com ARS KC7GR (Formerly WD6EOS) since 12-77 -- kyrrin(a)bluefeathertech.com "I'll get a life when someone demonstrates that it would be superior to what I have now..."

XT slots (was: RE: IBM 5161

by melamy＠earthlink.net

after checking in my IBM XT reference manual, the fact is that they added a buffer to the normal data and address bus and sent buffered these signals into J8. Also, they added a 14.318mhz oscillator on the expansion chassis side because they did not want pass this high of a frequency over the cable. This does mean that the manin 14mhz and the expansion chassis 14mhz are not in phase. The added buffers make the timning in slot 8 a littl emore tight because of the added delays through the additional chips. Slot 8 also had a requirement that it supply a card selected signal back to make sure the card was really ready to be accessed. The buffering from an engineering standpoint was done to increase the drive on the cable to the expansion chassis as well as help isolate the rest of the system bus from any added capacitance and noise from the outside world. best regards, Steve Thatcher >--- Original Message --- >From: "Fred Cisin (XenoSoft)" <cisin(a)xenosoft.com> >To: cctalk(a)classiccmp.org >Date: 4/2/03 12:36:58 PM > > > >But in the XT, one slot is different. >> > Why? > >On Wed, 2 Apr 2003, Ethan Dicks wrote: >> decided it was easier to give away a serial card than deal with the >> customer-support issue of random 3rd-party cards not working in that >> slot. > >But "WHY?" >Did they leave off the buffer chip BECAUSE the serial card didn't need it? >Or did they use the serial card to cover up a MISTAKE? >Or did they have some OTHER plan for it, and used the serial card as a >"placeholder"?

IBM RS/6000: PS needed

I managed to pick up a near-complete RS/6000 model 250 (7011-250) today, complete with ram, disk, framebuffer, sound card, and video capture card...

Two ESDI drives available

Well, I've made up my mind. Actually, I found a controller for these drives and have installed them in a computer I use to emulate the old Tandy's I collect. How's that... Emulating a 20 year old computer on a 10 year old computer with 15 year old hard drives. Now, on to the next question. I need a 34 conductor flat cable with male IDC on one end and socket on the other. Anyone know of a good source for these?

Victor Keyboard Identification

by thosmm＠yahoo.com

Rob, It's an enhanced keyboard from a Victor 9000 system. They were built in the early 80's and were pretty good machines. 80 track 5.25" disks held 1.6MB and ran CP/M-86 or MS-DOS. 800x400 graphics mode, although most were monochrome. You can also see them labeled as Sirius machines from time to time.

Since it is a standalone, I don't know how one could easily transfer it with HDOS. Still, I think I can come up with a simple serial to disk boot strap that would allow one to dump it from a PC onto the H89 disk, through the serial port of the H89. I've done this for several other processor ( like my Poly88 for tape images and my IMSAI to bring it back to life ). It has been a long time since I've looked at the disk EPROM's access methods. I'm sure I can figure it out and get something going. That way you could save the disk as an image file and all one would have to do is enter a small boot strap program from the monitor to get it going. I've always felt that this was the way you should be maintaining the library since it is simpler than sending media around the world. It does require that the machine in question have a code monitor or possibly a location to install a bootstrapping EPROM at worst. In any case, it would be good to get my Forth and the HDOS stuff I have transferred to something that can be easily distributed. Dwight > >> It has been a while since I had the machine running.

Gernsback Publishing closing

by RCini＠congressfinancial.com

Hello, all: I just got my latest copy of Nuts & Volts last night and to my surprise, there's a note from Larry Steckler of Gernsback, the publisher of Radio-Electronics and Popular Electronics (merged into Poptronics). He says in the note that Gernsback Publishing is closing after 94 years and N&V will be fulfilling the balance of the subscriptions. I pass this on to the list with mixed emotions. For many years I subscribed to both R-E and PE but once I found Nuts & Volts, I did not renew either subscription. They strayed too far from the content I liked and N&V had some interesting regular columns -- Amateur Robotics and BASIC Stamps -- that more closely followed my interests. I had the same feeling when Byte, well, bought it, in 1995 -- a formerly great publishing that lost its way and its relevance to its core readership. Rich ========================== Richard A.

I haven't got the battery pack, maybe you can build one buying the adecuate batteries. But, now, I am asking something to you. Do you have the owner manual of the machine (better if you have an archive with this and the technical information)? The machine that I have is not working and I am looking for technical information. thanks, Julio

Zebra Pick manuals

by cb＠mythtech.net

>If the pick box is small, I'd be interested if it's available. :) The Zebra machine is LONG gone. One of my first tasks at this company was to replace it, that was some 13 or sheesh, maybe 15 years ago. There were two of them I think, and I know I tossed them in the dumpster (this was before my collecting days when I just didn't know any better). The two PC's running pick: One was dismantled, the DigiBoards have been repacked and stored, and the hard drive has been put in storage (with Pick still installed). The rest of the PC I think is either in storage or has been stripped of parts (it honestly might still be standing on end next to my desk... I get so used to seeing things in my office that I think of them as furniture and forget all about them). The other is sitting in storage in one peice, in theory it could be booted tomorrow, but it has been offline for probably about 5 or 6 years now. I think it might have a broken DigiBoard in it as well. I seem to recall that a capacitor was snapped off one of the DigiBoards at one point. What I don't remember is if it was one being reboxed (makes sense) or if it was one that was left in the whole PC. I'm not at the point of getting rid of the whole one yet. It was saved in its runnable state because it has an old job on it that we wanted to be able to just drop back in place and run again if we wanted to. Although, at this point, even if the client DID restart the job, I suspect they would have enough changes to it to make it worth while rewriting it on a newer system. -chris <http://www.mythtech.net>

Cool finds!

by rigdonj＠cfl.rr.com

Stopped by one of my better scrounging places yesterday. I left with a new PC CMOS RAM card. This card has on-board battery backup, utilities in on-board ROM, write protection ability, and can be used as a solid state RAM drive and you can even boot from it. Also got the manual with it :-) Other goodies include two of the MS-DOS co-processor cards for the HP 9000 series 200 and 300 computers. I don't need to run MS-DOS on the 9000s but this card is required before you can use the HP 9127 drives to read and write MS-DOS formatted disks. I've got a heap of 9127s so the cards are very welcome. Anybody have docs or SW for these? I'm not sure if SW is required to use them to read/write MS-DOS disks or not. Also found a NICE little 5 slot VME chasssis made by Performance Technologies. It has two cards in it but I haven't checked it out yet to see what they are. Also found a nice counting scale with a remote scale. Also a big pile of Endevco Charge Amplifiers. Parts of a HP VXI chassis. Also found a 19" rack with a Recognition Concepts Inc Trapix 2d system. The odd thing about it is that the cards appear to be exactly the same size and connector layout as DEC Hex-bus cards! In the same chassis was a rackmount PC. It was connected to the RCI system by several LARGE ribbon cables and appears to be the I/O and storage system for the system. I didn't see much use for the RCI system so I left it but I grabbed the rack mount PC and a second loose rack mount PC that seems to be a spare. Joe

Ignoring Mount requests on startup in OpenVMS

by runtime＠wzrd.com

This might work, if you can get at EDT in the state before SYSTARTUP_VMS executes. I haven't tried it to see if you can. http://h71000.www7.hp.com/wizard/faq/vmsfaq_004.html Who remembers how you could interrupt an RSX startup and then, with luck, PIP your way out of trouble with files that shouldn't have been there?

AXP 7000 startup, now doing OSF/1

by gunther＠aurora.regenstrief.org

Hi, I have installed OSF/1 on the AXP 7000 and it's working. Quite a bit more snappy than the VAX6460. Man, I have no room for this machine left and now I love it so much! I'd give you login account (over my dialup IP) just the problem I am having is that after I built the custom kernel it still won't let any user other than root login. It says "too many users logged in alread, try again later". And that with zero users logged in at the time. Can you think of any file I might be overlooking? I can only think of /etc/nologin or something. My maxusers is at 32 in the kernel configuration. I can't think why this would not be correct in the kernel. regards, -Gunther

Looking for....RL02 controller for PDP-8E M8433?

If you have an 8/E, I'm afraid an M8433 won't be any use to you, because it's an RL8A, which is a hex board, not a quad one. It's meant for a PDP-8/A. -- Pete Peter Turnbull Network Manager University of York

hp-85A & 128K mem module question

Innfogra(a)aol.com wrote: > Does anyone know what command or process you would use on a HP-85A to verify > that the 128K Memory Module that plugs into the back of The HP is working. The Instruction sheet for the HP 82907A (32K), HP 82908A (64K) and HP 82909A (128K) Menory Modules states: "The HP 82907A, HP 82908A, and the HP 82909A Memory Modules cannot be used with the HP-83 and HP-85 Personal Computers." The note obviously refers to the HP-85A, since the HP-85B *can* utilize these modules as RAMDISCs. So you need either an HP-85B, an HP-86, or an HP-87 to use your 128Kb module. > I seem to remember that the 85A needs a ROM to use a 128K Memory Module. You may be thinking of the 00087-15012 Electronic Disk (EDISC) ROM which allows memory to be used as RAMDISC. This ROM is built into the HP-85B while it is optional for the HP-86/87. Sorry. **vp

Hacking an RS-170 tap into a B&W TV set?

by erd_6502＠yahoo.com

Tony (and others ;-), How does one go about looking for the right place to install an NTSC video input jack into a B&W TV without schematics? I have the "Cheap Video Cookbook" which describes the technique, but I'm trying to do this to a $20 K-Mart 4" B&W TV set (Spectra Model 52-BWR). Among other appeals, it's battery/auto/AC powered and should work great with, say, an 1802 with an 1861 (Elf, VIP, et al). Good portable demo set for low-res graphics. If it helps, the largest IC appears to be marked as follows... CD5151CP EP3 II DE028 Thanks. -ethan

H89/H19 keycaps?

by erd_6502＠yahoo.com

With all the discussion of Heath terminals, I am reminded to ask if anyone has any keytops? My H-19 came to me with one key missing (and a piece of paper stuffed betweent the contacts!) It's one of the keys on the corner of the keyboard (probably got whacked by my former boss), not one of the letter keys, but at this point, I'd be happy to get *anything* to replace it, no matter what the legend. Does anyone have a dead H-19/H89 keyboard they could spare a keytop from? Write off-list if you do. Thanks, -ethan

Looking for Arche Technologies Computer, iRiS anti-virus software ($$$)

by vcf＠siconic.com

I have a new bounty. I'm looking for two things which are somewhat related. First, an Arche Technologies PC-compatible system. This was a typical 286 clone from the 1987-1989 timeframe. Second, iRiS antivirus software. This may have also went under the names of "Virus-Free", "Antivirus" and "Antivirus Plus" (sometimes in combination with the company name "IRIS"). The software was distributed by Iris and the software apparently written by Computers of Israel. The iRiS software was included in the system software that came with the Arche computer. It is the software that I am really after but the computer also has some use. There is a bounty for these items. If you have them, contact me directly at <sellam(a)vintage.org> and we can negotiate a fair price. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

H89 as serial terminal

by dwightk.elvey＠amd.com

Hi I have a stand alone Forth ( FIG ) that I did years ago when I first got my H89. It runs on the hard sectored disk. I don't have any C for this machine but I do also have the BASIC in HDOS. On the hardware methods, one could run both connectors, >from the terminal and CPU board to the back and make a short external jumper cable to change it back to a computer. This would allow one to use it either way. The only thing one might want to open the cover for is to set the baud rates for correct use as the computer or terminal. Dwight >From: "Jason J. Gullickson" <mr(a)jasongullickson.com> > >Hey guys, thanks for all the info. > >I would prefer to go the software route (I'd prefer to run CPM and find >a C compiler...) but I'm having a hell of a time tracking down disks for >this thing so in the meantime I'm looking for a hardware hack to make it >useful (or at least make it do something to freak out my fellow >employees as my syslogs scroll across the screen of this beast), so the >hardware solution is what I was looking for (I could have been more >specific). > >On that note, if any of you know where I could find a copy of CPM and a >compatible C compiler on hard-sectored disks, that would be greeeaaat, >yeah. > >Thanks again! > > > >-----Original Message----- >From: cctech-admin(a)classiccmp.org [mailto:cctech-admin@classiccmp.org] >On Behalf Of Patrick Rigney >Sent: Friday, March 28, 2003 1:02 AM >To: cctalk(a)classiccmp.org >Subject: RE: H89 as serial terminal > > >> >much easier than any of the above... get a copy of MDM712 or similar >> >terminal emulation program.

8080 disassembler

What features do you want or need in an 8080 disassebler that you haven't been able to find? I recently went looking for 8085 disassemblers for the monitor ROM in an HP 5036A microprocessor trainer. I didn't like much of what I found either and I ended up just writing my own. It really wasn't that difficult and had the benefit of being able to exactly control the listing format as I wanted. >Does anyone have a good DOS or Windows based 8080 disassembler that they >would recommend?

dbit E11 and rtv53_rl.dsk

by rhudson＠cnonline.net

I have a machine dedicated to DOS, and I have found that dbit's pdp11 emulator works under DOS (I wish sim worked under DOS) Is there any way to get RSTS or any other pdp11 os running in this environment? Anyone know what rtv53_rl.dsk is? I think it's a RL disk image of version 5.3 of uh I used to remember. Is RT a pdp11 OS? if so anyone know how to get this running? Thanks!
