Morrow Radio Mfg Co. Salem, Or. ? and/or Heathkit Technical Applications Bulletins?

by rigdonj＠cfl.rr.com

Does anyone know anything about this company? Or if it's related to Morrow computers? I found this address on the instruction manual for Morrow convertors. The convertors were super hetrodyne tuners for use for auto radios and would allow the reception of 10-15-20-40-75-80 meter stations. I found this manual in a binder of Heathkit Technical Applications Bulletins dated 1952/1953. I've never even heard of these bulletins before but they look pretty interesting. Does anyone know more about them or when Heathkit stopped printing them? Joe

HP1000 Card Edge Connectors

by glenslick＠hotmail.com

I think the necessary connector is a dual row 48 contact 0.156" spacing card edge connector. I'll have to see if I can find a source. I think some place like http://www.edac.net would let you specify such a connector, but actually buying some in low quantities might be a different story. -Glen >From: "Will Jennings" <xds_sigma7(a)hotmail.com> >Reply-To: cctalk(a)classiccmp.org >To: cctalk(a)classiccmp.org >Subject: Re: HP 2647A / F Terminal & HP1000 >Date: Wed, 23 Oct 2002 10:52:43 -0600 > >Closest I ever came to cables was the hacked-off ends as gold scrap : ( > >Will J _________________________________________________________________ Surf the Web without missing calls!

Classic Computer Question

by Huw.Davies＠kerberos.davies.net.au

OK, this is a long shot but with this group, you never know. I'd like to try to identify the first computer I saw "in the flesh" so to speak. This would have been 1965 or 1966 and it was at Keele University (in the UK). Does anyone have any suggestions as to how I would find this out? I've already tried sending e-mail to the computer centre at Keele a few years ago but didn't get very far. Whatever computer it is has a lot to answer for! Yes, I'm getting old but I was 10 or 11 at the time.... Huw Davies | e-mail: Huw.Davies(a)kerberos.davies.net.au | "If God had wanted soccer played in the | air, the sky would be painted green"

Reading floppies under Linux

HP9100 Calculator

by martin.kaeser＠auge.de

Hi all, i bought a HP 9100 A calculator and need some advice. According to the owner, the power supply hummed and the backlighting came one - nothing on the screen, though. I think i should test the power supply and the tube first. Any suggestions on where i could test voltages and what i should get? How long would the screen take to light up? If the calculator is stuck in a loop, would there be a display at all? Would pulling the logic cards first be a good idea? Thanks for advice, Martin

Naming Computers [ was: Re: A Momentous Decision ]

by carlos_murillo＠epm.net.co

I started with mountain names (heck, everyone does, but then I *really* like some mountains). But I tried to use original names whenever possible (citlaltepetl, popocatepetl, iztaccihuatl, jimulco). Then I followed with aztec deities (coyolxhauqui, chimalpopoca, tezcatlipoca, huitzilopochtli...). Nahuatl language is just great for naming hosts.

Someone was looking for a Packard Bell power supply

by cb＠mythtech.net

A while back I was talking with someone from this list about a Packard Bell power supply they were looking for. We decided that the one I had wasn't the right one... but just a few minutes ago, I stripped a Packard Bell 486, and have its power supply. So whoever that was, if you are still in need of one, email me, and we'll see if this one fits your case. -chris <http://www.mythtech.net>

DEC wiring colors and the PDP-8/e PSU

by erd_6502＠yahoo.com

I think I have repaired the circuit breaker in my PDP-8/e, but in my efforts to reassemble the dismantled breaker, I am concerned that I might have swapped the hot and return wires (black and white) from the mains plug. For internal AC wiring, I have seen in this power supply and others (of the -8/i and -8/L vintage, among others) white and red wires. Is it white-to-white, black-to-red? The problem with my breaker turned out to be curable by tightening up the pivot points of the double-jointed contact-throw mechanism. The design, it seems, depends on the back-pressure of the movable contact into the fixed. One breaker stayed extended, while the other collapsed before the throw was complete. As there is a linkage that trips both at once, that's all it took. I think there was excessive side-play that meant the weaker breaker couldn't stand the pressure at the main joint and it popped. Before disassembling it, the symptom had been that I could reset the breaker dozens of times in a row and never have it stick. Now, it seems quite mechanically reliable. Haven't applied power yet, for obvious reasons. Thanks for any tips. If anyone happens to have their PSU dismantled enough to see the back, I need to know which half of the breaker, white-lead or black-lead, attaches to the lone white wire, and which one attaches to the red wire (with a companion wire). Thanks, -ethan __________________________________________________ Do you Yahoo!? Y! Web Hosting - Let the expert host your web site http://webhosting.yahoo.com/

Favorite terminal

by emu＠ecubics.com

Hi, what is THE favorite terminal you folks here use ? Now I have all this nice VTxxx I ever wanted, but they always miss the graphics capabilities, I had on my terminals in the office. (not talking about GUIs, just few nice lines on the screen) So, is there something like emulating VTxxx (52,100,200,320,340) and tektronix ? (probably even 38400 baud ? I really like to talk about terminals, not software for PC's emulating those ... cheers & thanks

CP/M for DEC VT-180?

by classiccmp＠crash.com

I recently gained a Pro-350 and a "Robin" VT-180. I know where I can get various bits of OS for the Pro, but nothing for the Robin. I've checked the two CP/M archive sites I knew about and done a little Googling -- I didn't find anything, though I did see a pointer to Don Maslin and get the impression he may be able to provide disks for some sort of fee. Anybody have a pointer to something on the 'Net? There's nothing like instant gratification, y'know... ;^) Thanks! -- Ob.

Naming Computers

by classiccmp＠crash.com

Well, I grabbed the domain crash.com in the Great Internet Domain Name Land Grab of the early 90's. So when I'm naming machines, I have an overpowering urge to use Unix signal names. The firewall was Segv [.11], is now Hup [.1]; desktops have been Buserr [.10] and Abort [.6]; web server is Fpe [.8]; main file- server had to be Io [.23]. The higher numbered signals tend to vary from one Unix flavor to another, unfortunately... This only applies to working machines; collection machines are liable to get boring names like different deities, different pantheon per manufacturer. I know, I know, how predictable... In a previous life as IT guy for a smallish ISV desktop machines were named with input from the user, if they seemed likely to have a good idea or insisted. Lab machines would typically be named by vendor and sequence, as they were rotated/replaced on something like a 12-18 month cycle. The two fileservers I put together (to get them to stop cross-mounting everything!) got named Inode and Vnode... External FTP server got named Beyond, as I recall. When we brought in a big team of developers and ordered their machines on short notice, I went with another common theme: T lines and stops (that's "subway" to those not in Boston ;^) Servers became Redline, Greenline, etc. Machines became stops on these lines (Alewife, Copley, Kenmore, Lechmere, etc). The original plan had been stops for servers and nearby streets for nodes, but we were rushed... The name I'm still most fond of is the first machine I was allowed to name. I started working in the VAX Resource Center at MIT back in '89 and was handed a VAXstation II, some TK50's and books, and told to learn VMS from a system managers point of view (I'd been a user for a couple years). Since I was and am a big fan of Buckaroo Banzai I called it Yoyodyne.mit.edu (and YOYO::), and after I finished my VMS lessons it got reloaded with Ultrix 3.x/UWS 2.x. I got a lot of complements on the name; several people tried to tell me something about this Thomas Pynchon guy, but I was more interested in reading things by Henry Spencer or Rob Pike... ;^) Ob.

cp/m favorite?

by r_beaudry＠hotmail.com

>I am curious what your favorite cp/m system might be. I am getting an itch >for some late-70/early-80/pre-msdos kind of box. Well, - For portability, I like the Osborne 1. I had a Kaypro 4 '84, and I admit the larger screen was nice, but for 'cool factor', I just like the Osborne. - For a desktop/all-in-one, the Televideo TS-803 is my pick. The graphics capabilities are quite nice, and the screen is large for an all-in-one. Also a nice large clicky keyboard. Wish I had the 803-H, though (built-in hard drive) :-(. I do also have a Xerox 820-II (a fine machine), but I like the style of the Televideo case better (not as industrial looking), and the Xerox drives are external, so they just don't look as nice :-) - For taking up rack/desk space, I have a CompuPro S-100 system -- Dual CPU (Z80H and 80286), a separate box containing dual 8" floppies (Qumetrak 842 SS/DS, SD/DD), and a separate box containing dual 5.25" 96tpi floppies and a 40 MB Hard Drive. All of this drives a pristine Heath H-19 terminal with a sweet graphics board. This is definitely my favorite overall system... - For a system that runs CP/M that wasn't designed to run CP/M :-), I like my Platinum Apple IIe w/ Microsoft SoftCard. I had a C-64 w/ the CP/M cartridge, and I also had a C-128 (which really was designed to run CP/M), but the IIe appeals to me. Especially the Microsoft CP/M card :-) (from back when they made good products :-)) Rich B. _________________________________________________________________ Get a speedy connection with MSN Broadband.

cp/m favorite?

by Robert_Feldman＠jdedwards.com

I remember hearing the Osborne likened to a VW, the Kaypro to a Chevy, and the Otrona to a BMW. I had an Osborne and Otrona, while a friend had a Kaypro. Between the Osborne and Kaypro, I'd probably go with the Kaypro now -- larger screen, slightly better graphics (IIRC), but it has a strange disk format that makes copying to other formats more difficult. The Otrona's still the coolest of the three, and if you can get an 8:16, you can easily use it to copy disks to/from IBM PC 360KB format. Desktop CP/M machines (as opposed to luggables) are a different subject, of which I have little knowledge. Always heard good things about Epsons, except that they often went down strange proprietary paths and never got much market share. Bob -----Original Message----- From: J.C. Wren [mailto:jcwren@jcwren.com] Sent: Monday, October 21, 2002 8:44 PM To: cctalk(a)classiccmp.org Subject: RE: cp/m favorite? And the ever popular Otrona, which I personally consider a little nicer than the Kaypros. However, for sheer cool, nothing beat the IMSAI. One day, I will have space to light mine up again. Living on a houseboat is great, but sometimes the space issue is a little frusterating.
