All: Does anyone have a pointer handy to utilities for merging and splitting ROM images? I have two EPROMs (high and low) that I need to merge into a single image for disassembly. Ultimately I'll need to re-split the image. Thanks!

cctalk Digest, Vol 39, Issue 33

by spliffrd＠inch.com

I just found a cheap NCR monitor mv0951a in a trashbin. Really small and compact so I snatched/saved it and brought it to the lab. Seems to be VGA but when i bent down to plug it in, I noticed it had a non-standard AC plug with 3 small blades! wtf? no one here recognizes it. I'm googling now. It would be a great little lab monitor if it's not 220v or some alien design. -Matt spliffrd at inch.com spliffrd.livejournal.com On Mon, 13 Nov 2006, cctalk-request at classiccmp.org wrote: > Send cctalk mailing list submissions to > cctalk at classiccmp.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://www.classiccmp.org/mailman/listinfo/cctalk > or, via email, send a message with subject or body 'help' to > cctalk-request at classiccmp.org > > You can reach the person managing the list at > cctalk-owner at classiccmp.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of cctalk digest..." > > > Today's Topics: > > 1.

Sphere system owned by Larry Pazzolo (was: VCF 9.0)

by aek＠bitsavers.org

I also have a large quantity of Sphere docs and a big pile of hardware, but it was part of a deal with Jim Willing that went bad. I have tried to get the stuff back, but he is not responding. -- It's probably sitting next to the Tektronix 405x documentation I never received. I don't think short of you driving to Kansas and watching him go through everything that he still has that you will ever see the Sphere stuff again.

OT Monitor glass question

by trixter＠oldskool.org

I found what I thought would make a nice spare Trinitron monitor, but there is a tiny pinhole chunk of the glass chipped out on the surface, about maybe 1.5 mm deep with a diameter of 4mm. Against better judgement, I switched it on (from a safe distance) and it appears to function properly. My question is, how stable is it? Other than the visual defect, is it safe to operate the monitor, or should I be worried that it will swiftly implode at any moment? -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/

Tales of Ancient E-Mail

by sdc695＠yahoo.com

<<<much deletia about early "first" email systems>>> OK, The first liar doesn't get a chance. Back in the 60's, Tymshare (the company) had a bunch of SDS (later XDS) 940 boxes and they DID have a "mail" command. The problem was that they only could mail between accounts on the same machine. Yes, it was an early form of email, but not routed between machines, only local use. While I don't know about other machines of the era (mostly time sharing boxes) and their "mail" commands, this machine DID have one. I found out (the hard way) that the messages were limited to a few characters (around 300 or so), but since you could share files between "accounts" (file systems were limited in the day), it could be useful to supply pointers to larger things. Thankfully this was before SPAM existed, as we only used mail for "proper" things. Other examples of machines of the day: pdp-6/10, IBM360, GE 235/635. I don't know about what was used on the pdp-6/10 (I have a bit of contact, but not much), but I don't remember any mail commands for IBM360's or the GE machines.

VAX 4000-200

by RodSmallwood＠mail.ediconsulting.co.uk

Hi I'm now the lucky owner of a Vax 4000-200. Apart from a bad TK70 drive (which I can get repaired in the UK ) Its fully working with 3 x RF 500Mb Drives (Two in a separate BA215 box) It boots VMS 3.2 and loads the network software. I even have all the license numbers for VMS 3.2, DW-MOTIF,TCPWARE, VAX CLUSTER & VOLSHAD What I don't have is the System password. The system was made in 1991 and had been out of use since 1998.00 I would like to preserve it as is, adding a contempory set of periperals (VT-100, LA-36 and so on) I don't want to replace the VMS or any of the other software. I have no option but to try and recover the system password. I'm not a hacker and have no idea how to go about breaking in. Anybody out there have any suggestions as to how to get in and recover the System password? Rod Smallwood

If anyone is interested, I have a boatload of Gould logic analyzers; I've photographed the innards of the K-450 and have it displayed on my forsale page: www.parse.com/testeq I'm selling them for $5-$15 (other models too) local pickup in Kanata/Ontario/Canada. I might be convinced to ship them if you want them in quantity and you arrange for a truck... The "classic computer" part of the story is that they are 8086 based, with 192kB of EPROM (27128s) and 512kB of RAM (41256 chips). :-) The photos are fun, at the very least.

lisadraw

by aek＠bitsavers.org

" If I had to make the statement, I would say that today's code is a lot more like the Lisa's than the Mac's." -- We are living in a very different world. No one but embedded systems people (and very few of them..) code the way it was done on the original Mac. Today, you have a product that often has a sub-year lifetime. You put things out that are just good enough to sell, and move on to the next generation. No one would buy a PC with the features that could be built with a team the size of the original Mac team today, using their methodology. The only way to get a competitive product is to use a lot of other people's code, because no one is willing to pay for foundation development, only product differentiation. I'm not saying this is a GOOD thing (this is one of the reasons I'm at the Museum and not a start-up) it is just the way products are built today.

VCF 9.0

by david＠classiccomputing.com

I would like to write about the show, it can also serve as a good prep for my next podcast where I will be talking about it. So, you asked for it! This was my first time at the original VCF, and I have only been to one other, the VCFe 1.0 in 2001. This was also my first time to the Computer History Museum. My wife was able to go with me, which made the whole thing so much more enjoyable. She not only supports my hobby, but actually really enjoyed herself in the participation. Living in Florida, the flights / layovers were a bit on the extended side - not so bad getting there, but coming back. We left at 7pm Friday the 3rd, got to Dallas about 9:20pm with a 30-minute layover, then arrived in San Francisco at 2:30am (our time, 11:30pm PST). Not too bad, but as our original flight was delayed an hour and a half, we had to fly into San Francisco instead of San Jose. We were able to stick to the same schedule times pretty much, but the cab ride to the hotel turned into $100 for 25 miles. 150% of the meter because of going outside the 15 miles of that airport! But we made it and the Marriott was a nice little hotel with excellent rooms. And an excellent free breakfast buffet! Kudos to Continental for getting us there on American Airlines too. On the first day, Saturday the 4th, my wife and I were in the Replica 1 workshop at 10am and that was a lot of fun. Vince Briel was great, very helpful and good company; a funny guy too. Some guys in there were done in like 40 minutes I think! By noon, we hadn?t finished, but Vince said that we could come by his exhibit and / or he would be back at the room Sunday at 10am. At Noon, Bob Armstrong began his workshop building the VCF COSMAC Elf 2000 kit. Both of these kits are very well made and just were so fun to work on. It was so much like stepping back in time 30 years and being a hobbyist computer kit builder. Unfortunately, the Apple @ 30 / The Garage Years panel with Steve Wozniak and three other early Apple employees started at 1pm (Randy Wigginton, Daniel Kottke and Chris Espinosa), so we had to leave the Elf workshop early. I really didn?t want to seem rude to Bob and hoped we could be back in there after an hour at most. That would not happen, I think the entire panel discussion was about an hour and a half. My wife went back to work on the Elf after about an hour. The discussion was very lively and good. The stories were fun and I heard about a few things that I?d never heard before. Jef Raskin?s Apple 1 was there in a case, as well as at least two other Apple 1?s. Sellam was part host, but Bruce Draper of DigiBarn headed it up. Also ?Captain Crunch? was in one of the front rows (John Draper). He spoke a little too. Sellam gave away a Replica 1 (per Vince) based on a puzzle at the end. It was Steve Wozniak?s name with the letters jumbled (I forget what this type of puzzle is called, it was stated). I learned why at the bottom of e-mails I have received from Steve Wozniak, it says, ?TV is wake zone.? He likes these sort of puzzles. An aside, before I knew I would be able to go, I wrote Steve and asked if I could send my copy of ?iWoz? in a return postage paid package for him to sign, and he agreed. He?s a nice guy. Instead of course, I was able to get him to sign it in person, as well as the Replica 1 (I got Vince to sign it too) and I got a picture with him. I?m not a touchy-feely person, but he would stand up, and put his arm around you for the picture. This was pretty cool. Also in attendance was Andy Hertzfield, one of the members of the original Macintosh team (see folklore.org). Being a big Mac fan as well, that was pretty cool, but what struck me was that he was also sitting in one of the front rows and listening intently to the stories, especially to Steve. He was just having such a great time and you could see the admiration he had. No big surprise, but this was one of his heroes! Even though he has worked with him at times, probably even heard this stuff before, he was a big fan too. Anyway, what really struck me was that Steve Wozniak also greatly influenced the Mac! He didn?t work on it directly a lot perhaps, but his earlier examples of engineering and his methods and standards were embraced by these later guys. Steve Jobs absolutely pushed his own will on the aesthetics of the box and much of the user experience, but Steve Wozniak deserves more credit than perhaps I had given him before. He didn?t just design the Apple 1, Apple ][ and Disk ][, but influenced so much more. That insight just sparked in me during the discussion anyway. I was able to catch Andy at the door before he left and get a picture with him and tell him what a fan I was. By about 3pm, Steve began signing stuff, probably for almost an hour. I finally made it back to the workshop room where my wife was still working on the Elf. Most had left or finished, but Bob was still there and had helped Tamara quite a bit. She really enjoyed the workshops and soldering, etc. We didn?t finish the Elf until we got back home. We were able to check out the VCF exhibit and market place floor for an hour or so, then left with a friend we had met for dinner. We had a nice dinner and discussion with him into the evening. On Sunday, we met Vince back in the room at 10am and stayed there until about noon. Andre' LaMothe started his workshop building the XGameStation Pico Edition (didn?t have enough money to build all three!). We had lunch at the Museum where Sellam?s wife was selling snacks and wraps and sandwiches. At 1pm started the discussion group featuring Lee Felsenstein about the Processor Technology Sol-20 30th celebration. The panel also included Processor Technology employees Aram Attarian, Diane Ascher and Drew Rogge. Again, this was a lively and interesting discussion of story telling and Q & A. A Sol-20 provided by Stan Sieler of Allegro Consulting. was given away with a drawing at the end. This meeting was perhaps a third of the size of the Apple one. Sunday all around was much slower than Saturday. A few exhibitors and sellers had left after Saturday too. My wife and I didn?t get to go to the DigiBarn, but we spent a good hour or so checking out the visible storage. It was especially neat for me to see some classics ?big iron? up close like the IBM 360, Sage, CDC super computers and Cray?s. Let?s see, as far as exhibits go, pictures are better of course. I will have mine soon. The sellers had some good deals with better than eBay prices for a Z-100, a couple of Lisa?s with profiles, and common Atari?s and Commodores. There was much more to see and do than we did, but we had a great time. With three kids, just time alone with my wife for a weekend was nice, so we weren?t sweatin? it. Sorry for the little book, I hope this conveys a little bit more to some about the show.

RA82 questions

by pat＠computer-refuge.org

So, Jay's talk about RA81's spurred me on to work on testing out my RA82 disks. I've got an SA482 which has 4 RA82's, and drive 0 seems to work just fine, after I unlocked the disk heads. :) The other three aren't working as well though, it seems. One seems to give a fault when it spins up, but after it spins up, runs the on-board diagnostics ok. The relevent log of the on-board diagnostics session are below (starting >from when I pressed the "RUN" button to spin it up): ------------------------------------------------------------- RA82> FRONT PANEL FUNCTION IN PROGRESS %RA82-COMPLETED TEST: SUBTEST:1B %RA82-COMPLETED TEST: SUBTEST:1C %RA82-COMPLETED TEST: SUBTEST:1D %RA82-COMPLETED TEST: SUBTEST:1E %RA82-COMPLETED TEST: SUBTEST:20 %RA82-TEST:DIAG SUBTEST:20 ERROR:4B UNIT:001 REFER TO SERVICE MANUAL RA82> %RA82-TEST:DIAG SUBTEST:20 ERROR:FE UNIT:001 REFER TO SERVICE MANUAL RA82> RUN DIAG %RA82-COMPLETED TEST:DIAG SUBTEST:02 %RA82-COMPLETED TEST:DIAG SUBTEST:01 %RA82-COMPLETED TEST:DIAG SUBTEST:04 %RA82-COMPLETED TEST:DIAG SUBTEST:05 %RA82-COMPLETED TEST:DIAG SUBTEST:06 %RA82-COMPLETED TEST:DIAG SUBTEST:07 %RA82-COMPLETED TEST:DIAG SUBTEST:08 %RA82-COMPLETED TEST:DIAG SUBTEST:0B %RA82-COMPLETED TEST:DIAG SUBTEST:03 %RA82-COMPLETED TEST:DIAG SUBTEST:1A %RA82-COMPLETED TEST:DIAG SUBTEST:1B %RA82-COMPLETED TEST:DIAG SUBTEST:1C %RA82-COMPLETED TEST:DIAG SUBTEST:1D %RA82-COMPLETED TEST:DIAG SUBTEST:1E %RA82-COMPLETED TEST:DIAG SUBTEST:20 %RA82-COMPLETED TEST:DIAG SUBTEST:21 %RA82-COMPLETED TEST:DIAG SUBTEST:22 %RA82-COMPLETED TEST:DIAG SUBTEST:25 %RA82-COMPLETED TEST:DIAG SUBTEST:26 %RA82-COMPLETED TEST:DIAG SUBTEST:27 %RA82-COMPLETED TEST:DIAG SUBTEST:28 %RA82-COMPLETED TEST:DIAG SUBTEST:29 %RA82-COMPLETED TEST:DIAG SUBTEST:2A %RA82-COMPLETED TEST:DIAG SUBTEST:0A %RA82-COMPLETED TEST:DIAG SUBTEST:0F %RA82-COMPLETED TEST:DIAG SUBTEST:10 %RA82-COMPLETED TEST:DIAG SUBTEST:0E ---------------------------------------------------------------- Looking at the manual, error 4B is "index pulse error" and FE is "Slave speed check timeout". Considering that they only occur when the disk is first spun up, is it maybe really ok, but the disk doesn't spin up as fast as the logic wants it to? The errors seem to be consistent (they happen each time I power up the drive). Has anyone seen something like this before, and is it something that I should be worried about? The service manual seems to suggest that the servo module or microprocessor module could be bad.

Help in identifying chip...

by alhartman＠yahoo.com

I have a load of these chips from NEC... Can anyone help me identify them? NEC D8041C It's a 40-Pin DIP Chip. And I've been unable to find any information on-line about it. We've come into a whole load of 74 and 75 series TTL chips as well as load of Relays and Power Transistors and other assorted parts. Once I get them all inventoried, I'll make a website. Hopefully listmembers looking for classic IC's will find this to be a useful cache of parts... Al Phila, PA
