Hi All I have just acquired a System 80 MkII (distributed in Australasia by Dick Smith Electronics). On power up I get the LED power light ok but a screen full of random characters, the reset switch does nothing. I've had it apart and there are no loose connections or chips on the two main boards and no sign of any burnt or expired components. Has anyone had similar problems and / or knows what the problem is? Thanks Alan

Digital Group equipment?

by jontitus＠attbi.com

Does anyone follow or collect Digital Group equipment? This company, based in Colorado, had some nice equipment that let users plug in various CPU boards, yet the same basic memory, I/O, and peripheral controllers worked for all the CPUs. Data storage used Phi Deck cassette recorders, although in its later stages, someone may have offered a disk-drive controller. The Digital Group computers were quite popular with amateur-radio operators.

Hi Rich I've found that it is usually not all that difficult to do. I've written code to handle DOS files on a non-PC machine. I have a friend in Germany that has written code to manipulate files from a Olivetti M20 ( Z8000 machine ) image file on a PC. This is using PCOS ( Olivetti's OS ). I wrote code to build disk images for the CPM8000 that I got up and running on the M20 as well. I've always felt that such activities, although time consuming, pay off later in the ability to handle new problems. Dwight > >Rich > >-----Original Message----- >From: Dwight K.

Dayton Hamvention (was Trenton Computer Festival)

>>Mendelsson's will probably have their large tent with pallets of slightly-crushed UPSes, ammo cans and other surplussy things. Refresh my memory, does Mendelsson's have a warehouse-like store in downtown Dayton, crammed full of retired electronics (and office furniture) ? I worked in Dayton many years ago and I remember spending some interesting lunchtimes in this warehouse-like store looking for goodies. Of course the one thing no-one should miss when in Dayton is - Marions' Pizza. Ask for it by name. Dave. The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com

I went once before 7 or 8 years ago but didn't really have time to take in all the flea market. Seems a shame to miss out on the Sunday dumpster dive and free 'stuff' but can't be helped. I have already cleared out the back of the station wagon in readiness for a large quantity of purchases. I think I need to get one of those wheeled trolley things you see people with at hamfests.

Trenton Computer Festival

by david_comley＠yahoo.com

I went on Saturday but skipped Sunday. Definitely worth the trip (120 miles R/T) although I didn't bring a whole lot home. I ended up with handful of TK50 tape cartridges (marked VMS5.4, but not sure if this is a complete set) and a scsi zip drive to replace the one I butchered 2 years ago. I passed on what appeared to be a 9-track tape drive and a Wang printer. One vendor was selling some VME components but other than that I wasn't tempted this time around. I wish I'd picked up one of the 68k Apples. I'm sure the Hamvention will have scads of them though. Regards, Dave The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com

>I also went to TCF on Saturday. [snip] Yowzers! Sounds like there was FAR more to be had on Saturday than Sunday when I went. I don't think I saw ANY Apple 2 stuff at all other than one guy with a box of software and a Cricket speaker box. (of which I meant to buy the stuff, but got side tracked answering a Mac question for my brother and then further side tracked by things to look at... before I knew it, I had walked away, and gone home and forgotten to buy the A2 items). I also didn't really see too many items older than 68k Macs and a few early Pentiums. I guess all that stuff sold off on Saturday. Looks like next year I go on Saturday rather than Sunday. -chris <http://www.mythtech.net>

by alhartman＠yahoo.com

Saturday was definitely the day to go. People offered me some stuff for free, because they were going to dumpster it. But I gave them a couple of dollars (usually the first price). Although last year, a guy sent me a TON of HP Laserjet IIp/IIIp parts for the cost of shipping. Which helped me fix a couple that I have here. I passed on a Power 100 (Power Computing PM8100 Clone) for $10.00. It was a logic board and I/O board in a case and PS with an FDD. No HDD or CD-ROM (though I have plenty of those..). But, I already have one. And didn't want to lug another home, just to have it sit in a corner. But, I was tempted.. LOL! I couldn't pass up the IIgs, and considering I have a unit that exactly duplicates it, perhaps I should have... But, it will make a nice gaming machine to give to someone and I have a few good games for it. And considering I still do the occasional maintenance on an educational program I wrote in the 80's, it's good to have a backup unit. Some people do leave stuff home, and remember to bring it back on Sunday though. So, early on Sunday you can find some things that weren't available on Saturday. And the last hour is the best time for dumpster diving! LOL! The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com

Northstar File Transfer from PC

by RCini＠congressfinancial.com

Dwight: I have a working N* Horizon system (dual drive, 56k RAM, monitor in ROM) and would be happy to lend my testing services. From time to time, I've wrestled with the same disk image manipulation issues for the Altair32 emulator, i.e., manipulating the disk image outside of the emulation environment itself. My conclusion was that there's no substitute for using the original OS for maniuplating the images. So, we developed several methods to move program files into and out of the emulator by using some home-grown and CP/M-native utilities and the file transfer functions of the terminal program on the PC. I really want to do an external "image management" program but haven't found a clean/easy way without essentially re-implementing portions of the base OS.

HP64000

by comley＠comcast.net

I brought home an HP64000 development system today. It has the emulation pods for the 68000 and 8080A processors, an HP-IB cable plus some other odds and ends in the backpack. A peak at the back indicated that it is crammed full of cards and 128K memory. Unfortunately what it doesn't have is either software or manuals, so this is a request to the group for help in that respect. I believe that there was a ton of software originally available for this unit to support various options and development tools, and I think what I am looking for is at least the operating system on floppy so that I can boot it up. Any background material on the 64000 would also be appreciated. I was impressed by the fact that it weighs almost as much as a model 33 Teletype yet it still has a handy reinforced carrying handle on the side for those portable sessions... Regards, Dave

FS/FT: VaxStation 3100 m38; C-128; Atari 800

by dwoyciesjes＠comcast.net

Well, in the process of going through my computer room, and sorting stuff out to keep, and get rid of; I've decided to get rid of 3 of my classics. They've sat around for too long, going unused. So... --- VaxStation 3100 m38 - 32MB RAM (maximum!) - 600 MB HDD in matching Storage Expansion Unit - mono video output - VR262 monitor (Don't think it works, might be a minor repair) it does drive a Digital VRT-17 fine on the green channel fine, though. - Installing & Using the VR262 manual - cables & power cords - including a MMJ cable & MMJ-DB25 adapter - 2 keyboards (IIRC LK201) - I'll make sure they work first... - Owner's binder - Customer Hardware Info/Planning & Prep/Owner's Manual/Network Guide - NetBSD 1.5 is currently installed --- C-128 & Atari 800 - both have 5 1/4 floppy drives, power cables, joystick - Bunch of games and apps Best offer. Pick up in New Haven CT preferred (especially for the Vax). The C-128 and Atari should'nt be that bad to ship, though. Cash, money order, PayPal. For trade, I'm looking for SCSI & IDE HDDs over 4GB, true-parity memory, PC100/133 DIMMs, P-III 800 CPU, 19" monitor... -- ---Dave Woyciesjes ---ICQ# 905818

If I look at the drive with an HP 9000 332 it sees an HFS partition - with basic 6.0 binaries :). When I ask the drive to identify itself it returns a pair of bytes that I don't recognise (1 and 15 from memory but I could be wrong). This pair of bytes is not the same as the pair that would be returned by a CS80 drive. I managed to check the reader software with a pair of 9133 drives, a 9134 drive (which fails) and a 7907 drive (this identifies itself correctly but appears to have been wiped of data at some time). I have some other software recorded on 7906 removable cartridges - does anyone know if an HPIB version of this drive was made? - I think that the model number may be 7906H but I have no further information. Does anyone have a 7906H tht they don't need? Cheers Peter Brown _________________________________________________________________ On the move?

Would you happen to have worked out the details in order to distribute the source code? I used to play this game in college many years ago, and it would mean quite a lot to me to get it up and running again. Thanks for any help that you can offer, Ken Carlin >From what I've read, banned inside of DEC is the best description :^) It >uses creatures and spells straight from D&D. Yep, I know exactly which one you speak of... I have the sources for the pascal version of the game, along with the data files, preserved for almost 20 years. I have ported the game to C using curses (actually, it was mostly a brute-force translation from the pascal) and have it running at least as well as the original pascal version (which was incomplete) at home on my Alpha PWS running Linux. I've been in contact with one of the people who was responsible for writing the pascal version, and am trying to get ahold of all the others so that I can figure out how to write up a 'copyright' page with proper attributions. >Basically all I know is what's written up at the following webpage: >http://www.io.com/~adastra/rancourt/dnd/ >It was written by Daniel Lawrence, started on the PDP-10, was ported to >RSTS/E part way through, and after that ported to VAX/VMS. I played it on RSTS/E when I was working at Parker St (DEC) in Maynard back in 1977. Actually, the pascal version was also built on RSTS using, I believe, the OMSI compiler, and ran on RT-11. Dan has apparently given permission for any and all versions of the game to exist with his blessing, but since the source I have had a copyright which is problematic (since it doesn't mention him), I have to try to do the right thing. >I grabbed the source off of the web page above, and it almost works.

I have a number of NOS plotter engines with nearly all (pre) cracked gears. I will be happy to loan you one, but I think you will find that your technique is not suitable for such a small gear. The diameter of the staple wire is about the same as the thickness of the plastic between the bottom of the groove and the bore. There are two gears per engine - X and Y. Same size. Same problem. One on the left, one on the right. I have used similar techniques (with success) fixing Atari joystick actuators (I used to get the joysticks for free from overenthusiastic friends with 2600s) You would have to get the plastic to mate up rather closely where the crack is - the "problem" is not that the shaft slips in the broken gear; it's that the gap causes the gear not to mesh with the driven gear and the gear train binds, preventing X or Y motion. > I'd be tempted to take a few 10ths of a mm off the inside of the hole > for the shaft that the gear fits onto.

The shaft diameter is 1/20" (1.27mm). If you enlarge the bore by 7%-14% (one or two tenths of a mm) off the inside of the gear, it will freewheel and fly off the shaft then get lost in the carpet. I have some closeup pictures I can e-mail to someone (no ftp access from the machine they are on) :-( The relative sizes of the gears are visible, as are the cracks. -ethan The New Yahoo!

Judging from the instructions, it seems that basically replacing SY.DVD on a disk with this new driver (and of course, having the right drive in the machine) would get it working. It seems plausible that the disk could have been made on a system with this driver. It comes with assembly source as well, and even versions for machines upgraded to 3- and 4-Mhz operation. No mods to the controller itself appear to be necessary. Let you know if you'd like a copy.

Most computer applications are simulations of one kind or another, word processors, spreadsheets, drawing programs, even a desktop GUI. Analog computers are the masters of the art of simulation, but they are not used for mundane simulations like these. Analog Computers run mathematical simulation of physical systems. Everything from the decay of subatomic particles to the interaction of two colliding galaxies. Do you want to: * See the results of a chemical reaction? * Test the design of an automobile tire? * Study the effects of pollution on a fish population? * Model blood flow through an organ? * Understand the effects of lowering the interest rate? * Fine tune the design of the Space Shuttle main engine? * Control flooding on a major river? * Explore new types of music? All of these are physical systems governed by mathematical equations. Analog computers are PURELY parallel and can run programs slower than real time, real time or faster than real time. Simulations can be halted at any point and all aspects of the simulation can be examined. Changes can then be made and the simulation can then be continued from the point it was halted or restart from the beginning. So, analog computers can not only simulate a fixed systems, but can also test 'what if' cases very easily. Analog computers can be a hardwired special purpose type or flexible general purpose type. The EC-1 with only nine amplifiers can be limiting in the size of simulations it will handle. But analog computers don't have the compatibility and the connectivity problem of digital computers. Ten EC-1s could be connected together to form an EC-1 with 90 amplifiers. The only problem would be if more than 9 integrators were used then a slight modification would have to be made to each EC-1 using an integrator to allow one EC-1 to control the mode. An EC-1 can also be directly connected to another brand of analog computer. No problem other than the mode control of integrators. The lure of the EC-1 is that it a inexpensive and compact example of vacuum tube computing. The world is analog. The human mind is analog. Digital computers make a nice hobby, and work just fine for tasks composed of sequential steps, but they are just an over hyped fad. --Doug ========================================= Doug Coward @ home in Poulsbo, WA Analog Computer Online Museum and History Center http://dcoward.best.vwh.net/analog ========================================= --__--__-- Message: 23 Date: Fri, 02 May 2003 11:59:27 -0700 From: Doug Coward <mranalog(a)attbi.com> To: cctalk(a)classiccmp.org Subject: Re: Heathkit EC-1 Reply-To: cctech(a)classiccmp.org Ethan wrote: > How does a resistive sheet computer work?

I wrote: > Resistive sheets belong to a category of analog > computing called network analyzers. Oops, I need to correct this. Resistive sheets belong to a category of analog computing called passive element computers in which network analyzers are probably the biggest and most well known examples. But it also includes * conductive sheets * electrolytic tanks - create 3 dimensional simulations * resistor networks * pin and rod systems * resistor and capacitor network Passive element computers normally models a physical system using only passive R-L-C components, and solve equations in which dimensions in space are the independent variables, rather than time. Applications for passive element computers include things like the simulation of * reception patterns of a receiving antenna * temperture, and pressure flow in a nozzle * diffusion of material at a transistor junction Here is an example: You solder together a large two dimensional matrix of resistors (all the same value). At each node where the resistors are soldered together you solder a capacitor connected to ground. You then apply a voltage to one corner of this resistor and capacitor network. As the current flows through the network it begins to charge the capacitors. You now have a computer that simulates the heat flow across a metal plate the size of your matrix, both over distance and over time. Without the capacitors you are simulating only over distance. A resistive sheet is a resistor matrix with a very fine mesh. The finer the mesh, the better the simulation.

I even dug into my old box of spare Elf parts and pulled out a small board with four TIL311 displays attached to a small microcontroller board - some kind of monitor/indicator given to me by the brother of the guy that got me into the 1802 as a kid. He had given it to me to harvest the TIL displays. I finally *looked* at the attached board to see what was on it - an NS 8073! I used to have access to an RB5X robot when I was a volunteer at the local science museum in High School - same chip - the hot-item-for-a-brief-moment microcontroller with embedded Tiny Basic. Now, rather than harvest the parts, I'm very tempted to reverse-engineer the schematic of the little board to see what it does. Looks like there's a small bipolar PROM, a 6116 SRAM, one or two TTL chips, and the TIL311s driven by the output pins of the 8073. The whole thing is only a few square inches. The funny thing is that I'd recently picked up a few 8073s from ePay to play with. I was planning on hooking them up to some 8031-based 8-line LCD displays I got for a few bucks each (originally out of some flavor of AT&T office phone, IIRC).

(It had a nice feel, kinda PS/2'ish, and no stupid windows, or various other internet/volume controls/etc keys.) I've had it for about a week now, and just can't get used to funky arrangement of the arrow keys in the middle, and the F keys on the left just throws my Unreal Tournament gaming off. (See http://www.northgate-keyboard-repair.com for some piccy's) Anyways, I gather these things were something of a 'gotta have it' keyboard at one time, and were bloody expensive. Thought I'd offer it up here, for 5$ + shipping before it goes downstairs in the basement to collect dust. One thing to note, is its got one of the AT style connectors in back, so you'll need an adapter if your going to plug it into a PS/2 style connector. (No, you can't have the one I was using) Visually, its pretty clean, there's a little green stuff on the bottom where I attacked (mostly ineffectively) some sticky stuff w/ a scrubbing sponge, but the top is (imho) nice and clean. I think all the keys work, however, there might be a few F keys I didn't hit the week I was using it. I gather it might of came with some extra keycaps when it was new, so you could move around control/shift. I do not have those. Anyways, enough disclaimers, Anyone want it?

This is very much like the resistive sheet methods. You place a power supply across one of the two planes that has shorts between them, such that about one or two amps is flowing in current limit. You place one lead of a volt meter on the opposite plane and then probe with the other lead on the plane with the current flowing across it. You find a line where the meter reads zero. Now, move the power leads to an orthogonal corners. Again fine the line of zero volts. Where the two lines cross, you'll find the short. There are variations of this method for finding shorts between traces and even multiple shorts.

So we know it's one of the sort with the Omni key instead of an inverted-T layout. If it's an Ultra, it should also have the function keys across the top. > Anyways, I gather these things were something of a 'gotta have it' > keyboard at one time, and were bloody expensive. Not that bad. In the mid-1990s you could get them for about $70, which seems expensive for a keyboard, but for those of us who really wanted the control key to be to the left of A and didn't want to have to fuss with driver software to make it happen, it was well worth it. If you want expensive, go check out the Avant Stellar! That is reportedly the modern Northgate OmniKey, and it sells for about $150. > I gather it might of came with some extra keycaps when it was new, so > you could move around control/shift. I do not have those. So, some questions to help folks ID what you've got. Is the control key to the left of A? Where are the switches? Poking out the back, or hidden under the "OmniKey" flip-top lid, or not present at all (flip the lid up, see nothing)? Not present at all means it is a late-model programmable keyboard. They had firmware bugs, and the "fix" was "remove the EEPROM that holds the key remappings". > Anyone want it?

One of the books that I found, HP-UX Concepts and Tutorials - Device I/O and User Interfacing, looked interesting but was still sealed so I listed it without opening it to see exactly what it covered. (I'm not real big on HP-UX). Today I found another copy of the same manual. It was alreadu opened so I've been reading through it. First, it DOES cover the HP IPC (Intergral Personal Computer) along with the HP 9000 Series 200/300, Series 500 and Series 800 computers. Each function that only applies to certain systems is flagged and there are appendices for the IPC and each of the other series that list and describe any peculiarities of that implementation. BUT what was even more surprising is that it states that many of the HP printers use the Amigo protocall! For the ones of you that aren't familiar with HPs that protocall is used for low end disk drives. This is the first time that I've heard that ! was also used for printers. Besides that statement it also has a "non-trivel" programming example of an "HP-IB driver that uses the Device I/O Library subroutines to drive various models of the HP Amigo protocall HP-IB printers". This might be a good starting point for anyone that wants to write and Amigo driver to talk to disk drives. Are you listening, Sergio and Peter? This book is definitely a keeper! It describes the HP-IB and GPIO interfaces for the various systems in detail including their status and control registers. It then describes how to use the DIL (Device I/O Library) included with HP-UX to set, read and control the interfaces and how to link calls to the DIL from Fortran, Pascal and Assembly language programs. It looks like a great source of info for anyone that wants to write their own device drivers or wants low level control of HP-IB and GPIO interfaces under HP-UX. I'm keeping this copy but I have another one that's already on E-bay. I know this sounds like a shameless plug but it's not. I'm just really impressed with this book.

Reading further I found, "There is no HP 9000 interface for the 13037 controller without an HP-IB adapter. The 7906H/HR ICD disks sare known not to work. The usability of the 7906S(slave) 7906A/B and 7905A disk is not known." Italics are HPs. I hope that confuses you as much as it did me! BTW the 13037 is some kind of MAC interface. I had one but gave it to Eric. BTW HP says that these drives are not supported under BASIC, HP-UX or Pascal! (at least at that time) It also says that no support is planned for any HP 9000 system. Also they state that these drives are obselete and recommend that people use the newer and more economical 7907A drives. I looked under the 7907 description to see if it would read the 7906 media but it doesn't say. However the 7907 tape media was 20.5 Mb vs 9.8Mb so it is different. The 7908 drive is described as 16.6 Mb fixed disk and a "1/4 inch "88140" shared controller tape drive". Most (all?) of the newer drives that incorporate tape drives are also described as 88180 tape drives so the drive and media used in the earlier 7906 and 7907 are different from the later stuff.

The first one was easy; just a memory chip (2102) that went bad. The second one is a bit tougher. I *think* I have the problem narrowed down to a Signetics 82S201 PLA, and therein lies the problem. Is there a replacement chip available, and is the coding of the chip available? If the coding is not availble, can I just go through a counter on the input and record the output states to come up with the chip programming? Needless to say, I am not real familiar with these devices :). There are two of these devices in parallel, and when I pull out the supected bad one (one makes no difference, pulling the other one starts the screen display again), the screen starts to work again. My suspicion is that the two are in parallel to increase the drive to the other chips. There are probably more problems since I don't hear the beep when the unit is turned on. The keyboard unit has already been checked out on the working Soroc. Any thoughts or comments? --__--__-- Message: 47 From: ard(a)p850ug1.demon.co.uk (Tony Duell) Subject: HP9915 To: cctalk(a)classiccmp.org Date: Sun, 4 May 2003 00:48:32 +0100 (BST) Reply-To: cctech(a)classiccmp.org I've recently had an HP9915 on the bench. This, as many of you are aware, is related to the HP85, but it's in a metal case with no printer, keyboard (although there is a keyboard connector on the back) or monitor (again, there's a composite video output on the back). Some details of the insides : Almost all the HP ICs are the same as those in the HP85 (CPU, CRT controller, RAM controller, Keyboard controller, ROMs, I/O buffer, even the printer controller is there). Much of the rest of the circuitry is similar to that in the HP85 (PSU, etc). There's an extra 8048 microcontroller that handles the power-on reset, self-test and autostart keys, and the front panel LEDs. It connects to the HP CPU via an I/O Translator IC, which is the same as the one used in the HP85 interface modules. Also linked to this microcontroller is a PCB that can contain up to 8 2716 (or 2732 if you rearrange the links) EPROMs. I have no idea (yet) how to format data to put in said EPROMs. The large board in the bottom of the case contains the PSU, and much of the logic circuitry. There are 6 'option ROM' spaces at the back of this board, identical to those in an HP85 ROM drawer. The PSU provides the same voltages, in much the same way, as the HP85 CPU. The output of the transformer is rectified and fed t oa switching converter (U30, 3524 is the controller IC) to provide +12V, -5V and -12V. This poweres a second switching converter to provide +5V. The +6V is obtained by a linear regulator. There is a crowbar (Q4) which will short out the input to the first PSU if the +12V line rises too high. This will then blow the mains fuse (something to check if the mains fuse blows at switch-on -- maybe Q5, PIC645, the first chopper is shorted). Another PCB plugged into the left edge of the main PCB contains the video RAM, printer chip (used here for the timers, I suspect), buffers/clamp networks for the keyboard and control connectors, a state machine to generate the video sync signals, and the composite video mixer. It has been suggested this is the 'operator interface' mentioned on the options box on the back, but I think not. I think this must be a standard part of the machine, and that the 'operator interface' is the keypad on the front. Talking of the keypad, the top 4 keys are connected as the k1-k4 keys of the HP85 keyboard. The blue key is connected as the shift key. On the back of the machine (actually on the vertically-mounted PCB that I mentioned a couple of paragraphs back) are 2 D connectors. The pinouts seem to be : Keyboard (DB25) 1 : chassis ground 2 : R0X (this is Row 0 output, buffered) 3 : R1X 4 : R2X 5 : R3X 6 : R4X 7 : Logic ground 8 : Logic Ground 9 : R5X 10 : R6X 11 : R7X 12 : R8X 13 : R9X 14 : C0X (Column 0 input, buffered) 15 : C1X 16 : C2X 17 : C3X 18 : C4X 19 : C5X 20 : C6X 21 : C7X 22 : KSX/ (Shift key, connect to logic ground to shift) 23 : KCX/ (Control key, ditto) 24 : KCLX/ (Caps lock key, ditto) 25 : SpkrX (Speaker output, return to logic ground) Control connector, DA15 1 : LED0X (High if top LED on frontpanel is on) 2 : LED1X 3 : LED2X 4 : LED3X 5 : LED4X 6 : LED5X 7 : LED6X 8 : LED7X 9 : RunX/ (RUN LED output) 10 : TestX (selftest LED output) 11 ; PWOX (Power OK output) 12 : Logic ground 13 : KeyStartX/ (ground for autostart key) 14 : KeyStX/ (ground for self test key) 15 : Chassis ground. The keyboard matrix would appear to be the same as that in the HP85 OK< a couple of questions 1) What is the impedance of the speaker in the keyboard (presumably between SpkrX and logic ground? 80 ohms? 2) What is the OD of the tape drive roller? Mine has decayed (what a suprise), and I need to rebuild it. It should be the same as the roller in the HP85, the HP9825, HP9815, etc.... -tony --__--__-- Message: 48 Date: 3 May 2003 23:53:08 -0400 Date: Sat, 3 May 2003 23:53:07 -0400 From: "R. D.

Northstar File Transfer from PC

Any information > appreciated! ===== Transferring from the N* to the PC ====== I developed a process for capturing the entire disk so would have a backup of each my N* disks on the PC. I figured that later I could use the data to create a disk image and then extract the files from that disk image. The procedure is basically reading sections of the disk into a buffer using N* DOS and then listing that buffer to a PC log file using N* monitor. Here is the procedure. The comments below are not part of the procedure and they are not captured in the file. They are just added to clarify the procedure. // Step 1 - While booted into N* DOS, turn logging // on in my terminal program (PROCOMM) // Step 2 - I type in the LI command to list the files // on this disk.

But I would just suggest that you write a N* BASIC program that first prompts for a filename and creates the file. Then the program would wait for data from the PC which it would store in a buffer before writting the data to disk. I would suggest sending the data as ascii encoded hex. --Doug ========================================= Doug Coward @ home in Poulsbo, WA Analog Computer Online Museum and History Center http://dcoward.best.vwh.net/analog =========================================
