I'm not sure what you mean by BIN files. Apple II software is usually distributed as disk images that can be use in an emulator or transferred to real diskettes. The files are so small (an Apple II disk is 140KB) that bittorrent is not used.

I never got to play with an 11/73 back in the day (we stopped buying PDP-11 gear around the days of the F-11 chip), but I would not be shocked to learn that the J-11 is twice as fast as a MicroVAX-I. It really is dog slow. It's a good thing the MicroVAX-II was much, much faster or DEC would have been in trouble long before they eventually got into trouble. -ethan

NRI-832

by tony.eros＠machm.org

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

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

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

Core memory Identification

by pontus＠Update.UU.SE

Hello. A member of the swedish forum called "odd hardware" on sweclocker.com recently got som old memory that he would like to identify. One is clearly HP, but it would be nice to know for which machine. The second a Prime memory, and the third is a _huge_ core memory and without any markings. Pictures can be found here: http://www.sweclockers.com/forum/showthread.php?s=&postid=9039862#post90398… The numbers on the HP memory are: 5060-8324 / A-1136-22 / 2304 The numbers on the Prime memory are: ART3572 REV E / PCB3573-001 REV E So, does anyone recognize these? I've done some limited googling for the HP board but came up short. Also, he seems willing to sell at least the HP board. Cheers, Pontus.

Oh, I was trying to be humorous about it. I write Verilog too; it's fun in its own way. I could just have easily grumbled about code bloat or not knowing how to write machine code (not assembly, but knowing by heart the opcodes and formats of a CPU). Or not being able to read the color codes on 6-dot mica capacitors. Or calling them capacitors instead of condensors. Or not being able to do neat point-to-point wiring using tie strips and waxed cable lacing. Or laying out 14 AWG busbar on mahogany breadboards between surface-mount (meaning that they're attached with woodscrews) components. Times change, and all too frequently, we don't. All we can do is grumble. --Chuck

I programmed in SPS for 10 years and was quite accomplished with it.? I love its graphics and data array handling capability. The High and low level support packages made driver construction a worthwhile effort as well. Sincerely, Bob Forgey Addy, WA Bob Forgey ADDY, WA

DEC Rainbow Interest

by rescue＠hawkmountain.net

Any interest out there in a DEC Rainbow. I may have one available. It's front badge is missing, but it does have memory expansion, hard drive controller, and 10M ST412 hard drive (and of course the DEC dual floppy drive). I do not have keyboard, video cable, or monitor. I can't verify full operation of the system due to that, but powering it on hd spins up (bearings may be a little noisy... I don't recall how 'quiet' an ST412 should be anymore :-) ). It does try to boot from floppy (but of course I have no floppy). It is very clean inside. Exterior isn't bad beyond the missing badge and a bit of yellowing on the floppy drive front. If you want to make any offers, that's cool. Also willing to trade/partial trade for VT-78/WA (WT78), DecMate I, DecMate II, DecMate III, DecMate III+, NeXT color or turbo color cube or slab, anything PDP-8, PDP-11/93 cpu board, any blinking lights/switches PDP11, Sun 1 (yeah, I might as well dream :-) ), Sun 2, Apple PowerMac G4 Cube, Atari 1200XL, Amiga 4000, Amiga 1200 -- Curt

NEC V20 files

by cclist＠sydex.com

Awhile back, there was a discussion about the NEC V20 CPU and someone asked about a couple of NEC-origin files. While looking for something else, I stumbled upon an old disk from NEC's Natick operation, given to me by Rich Naro. There is a V20 DEBUG program, some macros, a benchmark and some CP/M files to be run under the CPMulator program, but this disk does not include that program. If anyone's interested, drop me an email and I'll send a zip of the disk contents. AFAIK it is not proprietary, nor is it copyrighted material; merely something sent to NEC's customers. Cheers, Chuck

Considering Bidding (Apple Lisa in box on eBay)

by jdjdmfamily＠yahoo.com

Okay, I have been watching this auction for quite sometime, I am thinking about bidding.? What is it worth??? I don't want to over bid, but I've never seen an in box Lisa in good shape like that, and one with a working widget (come to think of it, I've never seen one with a working internal drive), and its said to have been owned by Apple. The item number is: 270351871785 Whats it worth bidding?? I would love to bid, and its stayed so cheap, I just want to meet the reserve, but if other bid (and there is also said to be 326 watchers), I don't want to get cought up in the moment and bid my life away, I just want to know whats its worth before I bid, you guys seem like experts in this area. Thank you, Rich

dumb rx01 image question

by brad＠heeltoe.com

[I sent this on monday but it seems to have been lost; sorry if it's a dup] I have a dumb question about rx01 image files used by simh. I used "copflp" (by John Wilson - thanks John!) to image a box of rx01 floppies. I then put the images on pc and used simh and I can see them fine with rt11 running under simh (i.e. "att rx0 image.dsk") But an old program I have which will read rt11 images does not see the directories. I am confused because it works fine with mscp image files that I connect to simh via an ra device (like an rd32). What's the difference between rt11 ra image files and rt11 rx01 image files? I would think the rt11 volume and directory info would be in the same place (but it seems I'm wrong). I tried skipping track 0 by offsetting 128*26 bytes, but that did not help. It looks like 128*25 might be a better offset for floppies. what am I missing? (and thanks in advance!) -brad

Looking for an 8 bit HD controller

by silvercreekvalley＠yahoo.com

The card I have at the moment is the xebec card with a WD25 drive (20M). I do have a ST-251 and a ST-225 to hand as well and probably some other MFM drives. A controller for any of these would be perfect :) I did see the ISA adapter but wanted to keep the machine reasonably original if possible. I checked the cables etc, but no joy. Thanks Ian

Anyone looking for a HP Micro 3000 GX?

by lee_courtney＠acm.org

BTW this machine runs the older (but still fun) MPE-V operating system on a 16-bit word stack architecture. Probably circa-early 1980s era business mini-computer. Not second generation PA-RISC 32-bit HP3000 architecture. If you've ever wanted to have a stack machine, this is a pretty good example. Nice small, albeit slow, HP3000.

Hi folks, Last weekend I found a couple of IBM 050 / 2495 tapes as described in this document: http://ed-thelen.org/comp-hist/IBM-ProdAnn/2495-5.pdf I seem to remember a discussion about these from a long time ago - does anybody know of any other surviving examples ? Sincerely, Erik

Anyone looking for a HP Micro 3000 GX?

by derschjo＠mail.msu.edu

Hey all -- doing some more cleaning. I have an HP Micro 3000 GX, (model 32536AH) I'm looking to offload. I inherited this when I was in high school from a business that was tossing it, and I haven't done much with it since. It looks like an interesting machine, but I've got too many other things to play with at the moment and figured there might be some 3000-series fanatic out there looking for a new toy (or just parts...) At one point it was booting some version/flavor of MPE but in the past few years either the hard drive's gone bad, or it's developed a few bad sectors. It does pass all power-on diagnostics, however. It has an 157MB ESDI drive, some manner of cartridge tape drive, 4MB of ram and 16 serial ports. It's a smallish (well, relatively speaking) tower-form-factor machine. It's in pretty good shape, but it's missing a few screws on the back panel from when I took it apart when I was 16 and lost a few. (Man do you ever have to take a lot of screws out to get inside this thing!) Anyone interested in this? I can't ship it (please don't ask!) as it's way too heavy (must weigh 90lbs) but I'll happily drive a bit to meet someone halfway. This is located in the Seattle, WA area. Drop me a line... Thanks, Josh

Anyone want some free RAM and CPUs?

by lproven＠gmail.com

I have a small pile of 4MB 72-pin SIMMs, both DRAM and EDO. At least a dozen, maybe 3-4 times that many. Anyone want some of them? I also have about 4 or 5 old Pentium chips. Just the bare CPU chips, not whole computers! All work, as far as I know, but they're old. I don't mean Pentium 2, 3, 4, nor even Pentium MMX, just plain old Pentium 1s. I think I have a 90MHz, a 100MHz and a few 120MHz ones. All free for the postage from London, England. -- Liam Proven ? Profile: http://www.linkedin.com/in/liamproven Email: lproven at cix.co.uk ?

2-problems with VAXstation 3100-76 and VAX 3100 10e

by parasang＠yahoo.com

Hi: Problem 1: I have two Vax with both with similar problems. One is a 3100 VAXstation-76 and the other is a VAX 3100 and both give a keyboard error. Both display a backwards "?" and then "VT420 Keyboard Error - 4" -- the 3100-10e shows VT320 error instead. The VAXstation has not run as yet, but I have had the 10e running in the past. Now both machines display an error. Both machines and peripherals (including the VT420 and VT320) were purchased through eBay. Problem 2: About two years ago I signed up for an openVMS licence. Since then I have been unable to get the operating system working or either Montagar or ENCOMPASS to give me little more than the time of day. It has been almost 2 years since this started and I have tried almost all that I can think of to get it settled. Hopefully you can suggest what to do -- I have gone 1 year past the licence renewal and no-one has even contacted me. Peter __________________________________________________________________ Yahoo!

Power MachTen hacking page (and Mosaic)

For those of you who need to run classic Mac apps (now that OS X 10.5 has killed Classic), but still need a locally running Unix/X11, I've been exploring MachTen and put up some thoughts on how to patch it up to "current standards." I also ported NCSA Mosaic to it.

Both machines and peripherals (including the >VT420 and VT320) were purchased through eBay. > Any time I've seen "keyboard error 4", it's been produced by a terminal. In theory, the terminal could be faulty but so far I've always found that either the keyboard plugged in to the terminal is faulty or there is nothing plugged in to the terminal where the keyboard should be. Problems with a keyboard attached to a VAX 3100 tend to produce much more obscure error reports including a bunch of hex numbers during the power-on tests. If you don't have a graphics monitor and intend to use a terminal as the system console, plug the keyboard into the terminal, not into the VAX. The little switch at the back of the VAXstation ("S3"?) then needs to be set to the correct position (it may be already). If this is not done, you can still log on at the terminal once everything is working but you can't use it for console commands and it will not be possible to install the operating system from scratch. Once the switch is set correctly and the terminal cabled up correctly, you should see the output of power-on tests on the terminal when the VAXstation is switched on. > >Problem 2: >About two years ago I signed up for an openVMS licence.

I've recently got hold of a pair of DECMate IIIs and would like to get them up and running with OS/278. Unfortunately they didn't come with any media so I'm wondering if anyone knows of a site that has some suitable boot images that I can copy onto 5.25" floppies with PUTR I've found some images on sunsite and update.uu.se however these are in teledisk format. Is it possible to turn these back into a straight physical image suitable for use with PUTR?

VCF West 2009

by sellam＠vintagetech.com

> So did we ever learn anything about VCF West 2009? > > I had emailed Sellam a while back but haven't heard back. > > In fact, when Sellam wanted someone to rescue that Microdata Reality > machine in Sandy, UT, I emailed him but didn't get a reply to that > either. Was the machine rescued? This was Sellam's original message: Hi Richard and Everyone. First, apologies to everyone to whom I'm currently obligated in some way. Things have been hectic for me for quite some time. The economic collapse has been particularly burdensome on my end, so I'm dealing with several major issues. On top of that I broke my ankle in a fall a few weeks ago. I just had minor surgery yesterday to remove some bone fragments. I'm trying to take advantage of the situation as best I can to use the time to catch up on things I've put off for too long. Regarding the VCF (the main west coast event) it will PROBABLY be back this year, as planned. I say PROBABLY in caps because I'm of the economic school of theory that says we are not coming out of this one as we went in, so I don't know what to expect by the time the VCF usually rolls around. All I can promise is to just wait for the announcement if there's a feasible possibility of pulling off an event. As you all know, there was no VCF (west) in 2008. Perhaps a (brief) explanation is in order. In 2007, at the milestone capping VCF X event, I had made it clear to anyone who asked that I was planning to take a break >from the VCF for 2008. Things were getting tougher and I knew that an economic collapse was coming. I also was very worn out from ten years of producing the VCF (not to mention my normal work) and looked forward to a year without the slow build of pressure that occurs in the lead up to each VCF event. Every year it became harder and harder to get going on the event, and so I knew a break was needed. And of course, right on schedule the economy collapsed. The VCF would have been right in the middle of it, so my prescience was vindicated. Do know that the regional events are all still on schedule, including a new South event in Irving, Texas tomorrow: http://www.vintage.org/2009/lite/ This is a "VCF Lite", not a full-blown event, but Gil Carrick (the organizer) will be expanding it to a full VCF event next year. VCF Europa 10.0 is on schedule for May 1-3 (a 3-day event!) in Munich, Germany: http://vcfe.org/ VCF Midwest in its new Chicago location is on track, but no announcement has been made yet. And VCF East has been scheduled for September 12-13 at the usual location in Wall, NJ (InfoAge Science Center). As far as the Microdata Reality, I have no good excuse for not having gotten back to the folks who inquired, other than laziness and a sense of being overwhelmed. I just sent out respones to those who inquiried, so thanks for the nudge. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

More surplus stuff

by jim＠g1jbg.co.uk

Hi All, more surplus stuff, this is for collection only! A number of PDP 11/73 systems. These systems consist of a rackmount BA23 box containing the standard PSU, processor, memory, two DEQNA and an Emulex serial port controller. They have no disk drive or controller - they net booted RSX11. Most of them have front panels, and I have some sets of rack mount rails (panels and rails only available with complete system). I probably have twelve systems available. Three Videcom terminals - unsure of the model number, but a fairly standard ASCII terminal. In exchange, I'm looking for some or all of the following: Tektronix terminal (4010 or similar) uVAX 1 or 2 cards (I have more of the BA23 boxes). PDP11/93 processor. PDP11/24 PDP 11/04 PDP8A (well, we live in hope....) Thanks Jim.

Fox electronics

by sellam＠vintagetech.com

Hi Brian. I've dealt with Fox Electronics on several occasions. They are primarily a chip recycler but also recycle other computer components such as hard drives and memory. I know Brad Fox (co-owner) and he's one of the nicest guys you'll ever meet. I sold him several batches of scrap circuit boards from my electronics recycling business over the past few years, plus other miscellaneous e-waste. One time I was there and he had a Terminator 2 arcade game that he gave me (which I recently traded for a Super Off-Road :) They used to be in San Jose but they moved their facility to Hayward. I don't know that they'd necessarily have anything in the way of retrocomputers, but it doesn't hurt to call and ask. There are so many electroncis recyclers now, especially in the Bay Area but also all over California, that most classic stuff that's still out there probably goes to scrap. My business occasionally gets some nice old iron, but definitely the bulk of it (99+%) is modern computer crap. Hitting these guys up to come out and look at their stuff will be a mixed bag. The smaller guys will, most of which are little one or two man shops, will probably welcome you, but the bigger operations probably won't unless you approach them more formally and explain your motives. Most of them are in it to convert electronics to scrap for pennies by the pound, and wouldn't know how to identify a vintage IBM from a modern one. However, if you give them model numbers, photos, etc. and specify a price over scrap, most of them would probably jump at the chance to make more money by selling the thing to you whole rather than put the labor into tearing it down to sell as scrap. With commodity prices at their current lows, it wouldn't take much to beat scrap values, with the exception being computers with boards that have heavy gold plating. Circuit boards are currently fetching around maybe $1.70-$2.00/pound, so even old HP gear can be had for very reasonable prices if you make an offer too good to refuse. Let's say a rack of HP 1000 equipment weights 500 pounds, perhaps 75 of which is circuit boards. Offer them $200 for it and they'll probably ask you if they can load it for you. Good hunting. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

A little more on the HP120 keyaord interface

by ard＠p850ug1.demon.co.uk

As I mentioned in another thread, I spent a little time inside my HP120 today. I've had another look at the keyboard interface. Of the 6 pins on the keyboard connector : 1 is not conencted 2 are +12V and ground 2 are outputs (machine to keybaord) and 1 is an inputer (keyoard to machine) The 2 outputs are a scan clock (pulse to move to the next key in the matrix) and reset (start at the first key again). The input is, of course, to indicate if the selected key is pressed. These logic signals operate ate 12V levels It is electrically indentical to the HP150 (origianl, not 150-II) keyboard interface. To the extent you cao plug an HP150 keyboard into an Hp120 without damage (I have done this after some careful checking). It doesn't work properly because the keyboard matrix is totally differnt (so keys to not produce the characters marked on them, and worse still, some keys don't exist), but it does something. The HP150 keyboard electroncis is quite simple. It consists of 5 4000-seires CMOS chips. A 4024 counter is driven by the 2 outputs from the computer (via diode/resistor protection networks). A couple of 4028 decoders, driven by the counter, with a 4011 gate to inver the D input of one of them, scan the columns of the switch matrix. A 4051 mux, also driven by the counter, cans the rows. And the output of that is is buffered by a couple more 4011 gates and sent back to the computer. By shorting outputs of the decoders to the inputs of the mux, I managed to work out most of the HP120's keyboard matrix. I how have a choice. I either copy the HP150 scan circuit (described above) -- the chips are trivial to get -- and wire up a matrix of switches. Or I make a little interface (presumaly using a microcontroller) to like a PC keyboard to the HP120. -tony

HP120 keyoard

by ard＠p850ug1.demon.co.uk

I've just picked up an HP120 (Z80 CP/M machine) on Ebay :-). The main prolem (mentioned in the listing I might add, so I am not complaining) is that it's missing the keyoard. The keyboard connector is a 6-pin telephone type socket (RJ12?). A quick look inside (well, what did you expect) suggests the keyboard interface is contrlled by an 8041 microcnntroller and that it works at 12V levels (not RS232, but 0V and +12V). There are +12V and ground pins on the keyboard socket. So I am looking for any/all of the following : 1) The correct HP keyoard (anyone know the model number?) 2) Details of any other keyboards that can be got to work. 3) Technical details of the keyboard interface. -tony

Fox electronics

by brian＠quarterbyte.com

Hi all Anyone have any experience with or know about Fox Electronics in San Jose (and/or Hayward) CA? I just saw their site and I'd never heard of them before. Their web site is pretty disorganized, lots of broken links, formatting problems and missing images. They seem to be an IC recycler/scapper. Anybody know if they have good stuff of interest to retro-geeks? Brian

Fox electronics

by aek＠bitsavers.org

> Anyone have any experience with or know about Fox Electronics > in San Jose Yup, they've been around for a LONG time, though never dealing in retail when I knew them. I had heard that Bob Fox had a serious car accident years ago, I don't know if his brother runs the place now. As you say, they are scrappers /chip pullers. When I was going over there, they had a place on Zanker, a couple of blocks down from where Excess Solutions was. There are lots of scrappers /chip pullers around still in the valley. Most deal only wholesale (ever wonder where Halted gets there stuff?) or just on eBay and really don't like to get walk-in customers.

PDP-8 Adventure on FPP-12 - who's the "local wizard"?

by hachti＠hachti.de

Hi folks, I tried to build and run adventure from Rick Murphy's website: http://www.rickmurphy.net/adventure.html I used the disk image from the page and booted my machine from it. I was able to compile and link everything by means of COMPIL.BI and LOAD.BI. When I want to start the game, I'm asked for the file locations. Then it takes a few seconds (perhaps half a minute?) until the program tells me about "Fatal error 8" - and that I should consult my "local wizard". But who's the local wizard? On SIMH it seems to work. At the moment, I would like to know if it's my machine and it's FPP-12 or the software (perhaps not expecting the presence of a real FPP-12?) which has the problem. SIMH doesn't have a FPP, so I cannot test it :-( I successfully ran maindec-12-dafpa-a-pb (FPP-12 data test) on my system. Compiling small FORTRAN IV programs und running them with the FPP attached seems to be working correctly as well. So are there any known problems? Might there be any problems? Is the adventure game tested with a real FPP-12? Does anyone know an emulator with FPP-12? My system configuration (abbreviated): * PDP-8/e * 32K memory * TD8E DECTape controller * RK8E RK05 controller * Teletype * Some serial ports for Kermit and dumprest If anyone knows anything, please let me know! It would be very good to be sure if I have a hardware problem or not. Don't want to search for a phantom problem. Best wishes, Philipp :-)

Yes... a common 1980s small office configuration. Pretty big for a single-user RT-11 system of the day (I was using a single RL01 for my OS and development environment and a single RL02 for customer data in 1986). Not so bad for a small RSX-11 or small RSTS environment (we were using a machine with only 4 RL02s for a RSTS-based accounting system for a multi-million-dollar company in 1984). > It came with two VT-100's and a LA36 DecWriter II.

The MicroPDP machines I've seen are in a BA23 (could be racked, could be in a desk-side pedestal), with a 1" MicroPDP nameplate near the power switch. It's spring-loaded, so you can pull it out and turn it 90 degrees for upright or racked orientation. > My college gave me a PDP-8 in a full rack with a fixed disk... Oooh... nice. What disk? RF08?

I myself held onto a Quest Elf for a friend who had to purge his place when he got married. I returned it to him many years later when he was divorced. He was 16 when he built it and its hand-made aluminum case and extra I/O to control the robot it sat at the top of. He was quite happy to get it back in perfectly working condition after so many years. I was happy for the use of it over those same years. -ethan

macintosh rom simms

by trag＠io.com

> Date: Mon, 9 Mar 2009 21:06:08 -0500 > From: Brian Lanning <brianlanning at gmail.com> > > It appears that the quadra 700 I just received from ebay has no rom > simm. Does anyone know where I can get one, other than waiting an > unknown amount of time for ebay to produce one? thanks. Every Macintosh from the II forward (well, probably not the Classic) was built with a ROM socket. However, the vast majority of them have ROM chips soldered to the board, and the socket is only there for updates which were never deemed worthwhile. Unless you have an incredibly rare Q700, there are ROM chips soldered to the board. They'll have a part number something like 343S0xxx or 341S0xxx and there will probably be four of them (each with its own, probably sequential, number), although there might only be two if they used 16 bit wide chips. I'm not sure if the Q700 is recent enough, but at some point they moved to 44 pin PSOPs for almost all their soldered down ROMs. Symptom of a missing ROM would be that the machine powers up just fine and all the drives spin up, lights come on, but there is no start-up bong and never any video from the monitor output. If the machine fails to power up all-together, then you have a different issue than lack of ROM. If you have a power supply failure, the power supplies from the IIcx, IIci, IIvi, IIvx, Q700, Centris 650, Q650, and PowerMac 7100 will work in the Q700. It was a long-lived power supply model.

by SupeduJour＠aol.com

Greetings David, Yes, I used a VideoWriter for years - got lots of good work out of it. But, it now sits, a broken man. My problem is, I have these discs that I can't seem to do anything with. They're filled with years of work and I can't access them. Please advise. I live in Nashville, TN. Maybe there's a place down here (up here) to retrieve the data. Thanks for your time, Michael Supe Granda 615-361-1685 **************A Good Credit Score is 700 or Above. See yours in just 2 easy steps!

The built-in SCSI is unenhanced SCSI. That means that its maximum theoretical performance is 5 MB/s. It's okay, but can seem a trifle slow. The best SCSI NuBus card only goes up to Fast & Wide (20 MB/s theoretical maximum). There are no Ultra-SCSI nor IDE/ATA NuBus cards for the Mac. If the thing has an original hard drive in, you could probably get some speed boost just by installing a more modern SCSI drive with a faster media speed. As slow as the built-in SCSI was in older Macs, the hard drives of the day usually couldn't sling data even that fast. > I still need to track down that goofy ethernet dongle that gives you an > rj-45. The connector is called an AAUI (Apple AUI) so you need an AAUI to UTP transceiver. Of course, if you're hunting on Ebay, there's no telling what the seller will call it. There were also transceivers for thinnet and thicknet, so do not accidentally buy the wrong one. Those things were cheap to free a few years ago. They may have all made their way through the second-hand system to the point where they're not as easy to come by now. If you have a Goodwill Computer Works store in your area, you might check their cable bins. Ours used to be full of the transceivers. > Date: Tue, 10 Mar 2009 15:49:18 -0500 > From: Brian Lanning <brianlanning at gmail.com> > On Tue, Mar 10, 2009 at 3:31 PM, Cameron Kaiser <spectre at floodgap.com> > wrote: >> A Radius card would go nicely in a unit like this, though. > > ok, so I'll start shopping for that. > > I'm having a hard time telling the difference between the video cards. > They all look the same to me although I'm sure some are better than > others. It's been a while since I checked, so my memory may be faulty, but I think that I remember that the built-in video on the Quadra 700 and 900/950 is faster than you're likely to get with a NuBus card. It's primarily a bandwidth issue. Telling the difference in NuBus video cards can be truly dizzying. The four main players were Raster Ops, Radius, SuperMac (not the later Umax owned clone maker), and E-Machines (not the much later PC maker). Around '94 SuperMac bought E-Machines. Not long after that Radius bought SuperMac. When they were being made, the NuBus video cards fell into two categories: consumer and professional. The late model consumer cards are good yeoman-like cards. The professional cards have some great QuickDraw acceleration on board. The fastest Mac NuBus video cards were the Radius Thunder IV GX series and the Villagetronic MacPicasso 340 (not the 320). I think Sonnet also sold the latter under another name. Raster Ops may have had a card in the same class, but I'm just not very familiar with the Raster Ops products. The Thunder IV GX series came in four models, 1152, 1360, 1600 and the Thunder 24/GT. The first three indicate the first number in the highest resolution of the card which supported 24 bit color. The latter, differently named card is just like the 1152, except it lacks the DSP daughter board. The IV GX models were about $3000 when new. The Thunder 24/GT was a bargain at just under $1000. All of these usually command a pretty high price if they come up for sale at all, but they are faster (in some functions) than a PowerMac PDS-based HPV card. They excel at tasks which are amenable to Quickdraw acceleration. They are still limited by NuBus' bandwidth and so are not so good at throwing frames up on the screen in quick succession. The late model consumer level cards include the Radius PrecisionColor Pro 24 series and the E-Machines Futura II series. Each of these contained three or four models which carried different amounts of VRAM. To truly muck things up, there was an earlier card called the Radius PrecisionColor 24 (no Pro) and the Futura (no II). The earlier cards were bigger and slower and less compatible. Again, Raster Ops probably had something too. SuperMac's last professional level card is often recommended by people and it's a good card by all accounts (I haven't tried one). The Futura II SX had a couple of optional daughter boards. One was a DSP coprocesser board, which isn't all that interesting these days. The other was an ethernet daughter board, which isn't especially enhancing in a Q700. The ethernet driver for the daughter board doesn't work with Open Transport and will freeze the machine at boot time if both the driver and Open Transport are loaded. The ethernet daughter board only works with Classic Networking. Okay, that's probably way more detail than you need, but how often do I get to dump this accumulation of now mostly useless knowledge out? Personally, I would just get the VRAM, unless you need support for larger displays for some reasons. Jeff Walther

Soldering to batteries - a word of warning...

by ian_primus＠yahoo.com

Well, I did something mildly stupid recently, and I did it even though I _knew_ the dangers. Some people might not know these dangers (or think about them), so I figured I'd post a word of warning, since this is bound to come up in classic computing. So, I was recently givin a copy of "Mario All Stars" for the Super Nintendo. It played, but the save game feature doesn't work. These cartridges use a battery-backed SRAM chip to store save games. So, my assumption was that the battery was simply dead. Opening the cartridge revealed the problem. The battery (a solder-tab style CR2032) was actually good, but the positive terminal 'tab' had come off. The spot-welds just let go. It must have been poorly made, and then got dropped at some point. I don't have a replacement battery with solder tabs, nor do I have a way to get one quickly. But, this seems simple enough, I'll just solder the tab back on. Now, I've soldered to coin batteries before and never had a problem. The trick is to rough up the surface of the battery so the solder can stick, and work quickly to avoid damaging the battery. Well, this battery wasn't having any of that. The solder simply would not flow. It was then that I thought "I can't heat a lithium battery too much - it might explode!". So I donned my full face mask and got back to work. More attempts to get the solder to stick were failing. I tried piling on more solder, so that the flux might have a chance to get it to flow. It looked like it was just about to stick and.... PFOOOF!! Yes. Lithium batteries _do_ explode when heated too much. The battery exploded sending bits of black crud and molten solder (that never stuck to the battery) everywhere. It suprised the hell out of me, that's for sure. I heard a little *plink* as the top cover of the battery landed behind me. I just stared at the bottom of the battery on the bench for a minute, startled. I took off the face mask and went to get the vacuum cleaner to clean up the mess. After cleaning up the debris and finding the battery tab and the battery cover, I was trying to figure out how to replace this battery - and if I should try soldering to another cell (more quickly, this time). I then looked over at my face mask on the table. It was covered with solder spashes, and quite a lot of it too (remember, I was trying to get the flux to help the solder flow). Had I not been wearing that mask, I would have gotten all sorts of crud in my eyes. I've always worn this mask when drilling, dremeling, using the table saw, and yes, when soldering to batteries. This is the first time one has actually exploded though. Yeah, it was my fault, I heated it too much - I should have known better. But it's easy to get frustrated and forget. But never forget to put on safety equipment when working with stuff like this. Givin the choice, I'd always rather have a piece of impact-resistant polycarbonate between me and flying shards of hot metal. -Ian

Yup, they had A/D converters measuring the returned photons. - John
