Has anyone used the NRI-832 that was featured in many correspondence course ads? I have one, but would really like to track down some documentation. I have a set of schematics, but that's all. Of course, I should be able to figure out everything I need to know just from the machine and the schematics, but construction docs or the course documentation would really be great. -- Tony

Vintage computing, relativity, and an obligatory parent brag

by tony.eros＠machm.org

Much to my wife's chagrin, I've been collecting vintage computers since 1986, when a PDP-8/e and an ASR-33 started me thinking that it would be neat to have one of every computer for which I'd ever written code. I did nearly reach that goal, lacking only a System/370, though I do have a Hercules emulator. When my oldest daughter Casey was in middle school, her interest in writing led her to ask me for a computer to use. I tried interesting her in one of my vintage systems. I figured OS/8 or RSTS/E would be overkill, so my PDP-8 and the -11s were out. I thought I'd start small. "How about this DECmate?", I asked. "Eeeeeww! I'd really like a laptop, Daddy!!". Okay... My Hyperion was also a non-starter, as was the Mac SE, even though I'd taken it on several cross-country trips and had a nifty travel case for it. A Bondwell (my first "laptop") didn't even make it out of its bag. Finally, she reluctantly agreed to use a "really old system" - a DEC HiNote Ultra: 75 Mhz 486 running Windows 95. I guess her definition of vintage computing is a lot different than mine... In truth though, she really was grateful to have the use of any computer at all. In February, writing under the pseudonym "Marian Watson", Casey submitted her novel, The House of Autumn, to Amazon's annual Breakthrough Novel Award competition. Her submission was one of 10,000 entries. After reading each of the entries, Amazon cut the field by 95%. Last week, Casey got the word that she made the cut and is one of the quarterfinalists! Amazon is providing free downloads of excerpts of the quarterfinalist entries and encouraging the public to read and post their own reviews. Since it's my job as a parent to brag on my kids' accomplishments, I feel compelled to pass along a pointer to Casey's excerpt: http://www.amazon.com/House-Autumn-Amazon-Breakthrough-Novel/dp/B001UG3C80/… In the upper right-hand corner of the screen is a "Download for free" button that you can click to get the excerpt. If you get a chance, give Casey's novel excerpt a read and post a review - it's pretty good. I'd like it even if it wasn't written by my daughter!! -- Tony Eros

apple 2e bin file source

by brianlanning＠gmail.com

I bought a catweasel mk4 plus the other day and it appears to be working fine. My son is currently playing boulderdash on a c64 from a disk I wrote in my xp machine. :-) I'd like to do the same for the apple 2e, but I can't find bin files anywhere. The usual torrent sites are full of amiga and c64 software, but not apple 2e. Does anyone have a source for these files? I especially need the appledos 3.3 and/or prodos disks. Thanks. brian

Monitors Available -> Tucson, AZ

by technobug＠comcast.net

Spring cleaning is underway and the following monitors of unknown provenance are available in Tucson, AZ for pickup: Sun 15" GDM-1604-15 (RGB Sync) DEC 17" VR295 (RGB) Apollo Model 010700-001(RGB) Silicon Graphics 17" CM2086ASG (RGB +unlabled BNC Sync?) DEC 17" VR320 (RGB) Silicon Graphics 19" GDM-20D11 These monitors were rescued from a scrapper with good intentions to checkout, but too many projects have interposed. I can also drop any or all off in Phoenix for pickup there. CRC

monochrome display

by slawmaster＠gmail.com

I'm working on getting a small VGA monochrome display; since I've never had such a thing, I need to ask: Is it easy to get a modern X server displaying nicely on a monochrome monitor? What's the deal? John -- "I've tried programming Ruby on Rails, following TechCrunch in my RSS reader, and drinking absinthe. It doesn't work. I'm going back to C, Hunter S. Thompson, and cheap whiskey." -- Ted Dziuba

What's needed for a minimal HP-1000 series E/(F?) system?

by derschjo＠mail.msu.edu

Boy, am I full of questions lately. If there's a good guide for this, please point me to it... I now have in my possession an HP-1000F system I got in trade and a mostly empty HP-1000E system I've had for awhile but haven't done anything with, because, well, it's mostly empty. The 1000F (2117F) has the following installed: Front: DCPC slot - D.C.P.C board 111 - Memory Protect 112 - M.E.M. . . . 121 - 64K HSM 122 - 64K HSM 123 - MEM CNTLR (cabled to 122 & 121 on left-side connector via ribbon cable) Rear: 10 - F.E.M. 12 - BACI 14 - BUS I/O The 1000E (2113E) is empty aside from the power-supply & mainboard and a single F.E.M. card in slot 10. The F.E.M. is cabled to the main board via a ribbon cable (this ribbon cable is not present on the 1000F). I assume this machine isn't going to do much as it is. Is the above enough to get a minimal system running (i.e. to allow toggling in programs via the front panel and testing the system?) Is there anything I need to know about how the cards need to be configured/cabled together? My understanding is that the F-series has some kind of floating-point support, but it's also my understanding that such support was provided via an external expansion, which I do not have. Since I don't have this expansion, will the 1000F work at all, or should I move the cards I have to the E? (Minus the F.E.M., I assume...) I probably won't have time to play with this right away, but I'm curious to know what else I'll need to get one of these machines going... Thanks, Josh

Norsk Data website

by axelsson＠acc.umu.se

Hi! It is not complete yet. As a lot of other sites it is a work in progress, but the work has reached the point where it is reasonable to show it to the world. What I'm talking about? The new Norsk Data wiki website of course! Last autumn I asked for some help finding information about ND-100 and now it's time to give something back. Have a look at http://www.ndwiki.org/wiki/Main_Page and tell us what you think about it. If you want to help us even better, just register and add information. :-) /G?ran

Looking for double density floppy drives

by brianlanning＠gmail.com

Hello. I'm in need of double density floppy drives to go with a catweasel. Apparently they work better making c64 and apple 2e floppies. I mainly need the 5.25" (360k) drive, but a 3.5" drive (720k) would be helpful also. The 5.25" needs to be half height, not the original 5150 style full height. I can trade for high density floppy drives or maybe other things. Please let me know if you have these lying about and are willing to part with them. Thanks. brian

Pascal/MT+ & Assembler Question - CP/m 2.2 and Disk formatters

by doug＠stillhq.com

Hmmm. After bashing my head against the wall for a while, I have decided to ask the list for directions (It's kind of like blokes and driving...) I have a little STD Bus CP/M 2.2 system for which I am trying to install 3.5" disk drives - Yes I know about the diferent speeds etc - but I am happy to do whatever it takes....The hardware stuff isn't that complex, I am using a 1793 disk controller, and I have good software control of it - actually ---- That's not totally correct yet! The original formatter for the system was written in Pascal MT+ - I have the source. It uses a short external assembly program to do the tricky stuff. I can compile the formatter - yay! It produces an .ERL file as its ooutput - I can also link it (using the pascal MT+ linker) with PASLIB, but I get unresolved references (ie the assembler formatter routines) - no surprises there.. I can assemble the assembly formatter - M80 =FORM4A and I get a .REL file as output. The bit I am missing is how can I link the two outputs into a single .COM file. L80 barfs at the output of the Pascal file, and the pascal linker barfs at the Microsoft file.... Help :-) Doug

NEC V40/V50 User manual?

by cclist＠sydex.com

Anyone know of a source for the NEC V40/V50 CPU user manual? In particuar, I'm interested in how the integrated peripherals are configured. The V40/50 datasheet is remarkably vague in this aspect. Thanks, Chuck
