Making an Atari 400/800 Basic cartridge Eprom type?

I bet it's a relatively ordinary pinout...probably the ROM version of a 2716 or 2732. I believe those chips have part numbers like "2316" and such, if memory serves. There were lots of mask ROMs that were pin-compatible with EPROMs in that era, before one-time programmable EPROMs (plain EPROMs but in plastic packages with no erasure window) became cost-effective. Are the numbers on your chip readable? If so, what are they? -Dave McGuire

Large hard disk

by alex＠linuxhacker.org

I have here a large hard disk drive which I know very little about. It is very solidly built of what looks like thick aluminium castings (with lots of fins) which has been anodised to a kind of light grey-gold colour. According to the bathroom scales it weighs about 37.5Kg or 85lb, and is about 40 * 27 * 34 cm or 1'4" * 11" * 1'1" in size. There is no control circuitry in or on the drive itself as far as I can see. The heads are connected to two 40 pin IDC connectors on top of the unit marked CN91 and CN92, the head motor is connected to a two pin plug marked CN93 underneath the unit, and the platter motor (which drives the spindle directly) is connected to a 5 pin plug marked CN94 to the left of CN93. There is an empty space for a CN95 connector next to CN94, and there is also a connector marked CN95 on the main drive motor itself (it looks like a position sensor). The mounting frame is shock mounted to the base via four rubber bushes. On the mounting frame is a label which says "B030-4840-T031A". On the top cover panel next to the head connectors is a label with two barcodes on it, one above the other. Below the top barcode it says "S/N A43396 REV B0". Below the bottom barcode it says "C/N 1A9840". On the casing above the head drive motor is another barcode label which says "S/N 3A43396". The main drive motor has a label that says: UGBT1D-TP0FU11 B90L-1560-0101A 24V 4A 701297-2 YASKAWA ELECTRIC JAPAN I don't have a digital camera, so no pictures I'm afraid. Does anybody know what this drive is, how old it is, what type of machine it was used with, what capacity it is, how much it cost when new, etc. Also, does anyone have a use for it? I'm willing to give it away to a good home, though I'd rather it was collected in person (from Burnley, in the NW of England). Failing that, I'd be willing to accept the cost of the postage (bearing in mind that it won't be cheap due to the weight) and a reasonable contribution towards the cost of packing materials and the effort involved in lugging the thing to the post office. -- ------- Alex Holden ------- http://www.linuxhacker.org/ http://www.robogeeks.org/

O.T.: Compu-Voxx

by bobcaar＠cyberdude.com

larry: I've got a couple of these units too. It records about 20 seconds of sound (at least mine do, I believe there were other models) and plays it back in a loop at the desired FM frequency. The input power is a 5 pin male DIN rated 22VAC and 20VA (reads on supply). Looking at the the plug, from left to right the pinout is as follows 1 4 2 5 3 (with standard DIN numbering, measured with multimeter): (1) 23V [between 1&2] (4) n/c (2)common (5) n/c (3) -11V [between 1&3 or 2&3] 1 3 4 5 2 I believe this unit only requires 22VAC between 1&2. These units were used in realestate to give a short blurb about a house. Apparently they retailed for $11 000 (?) back when the previous owner bought them.

Smith-Corona Daisy wheel supplies

by nerdware＠laidbak.com

Hi, gang. I'm going through boxes of stuff, and came across a pile of ribbons and several daisy wheels for a S-C printer that came with the one Kaypro II I was given. I'll never use all of these ribbons or even the alternate wheels....if someone can use them, mail me off-list and we'll work out the details. I'd hate to pitch 'em, but I need the room. Thanks.

Altair32 Emulator Project Update

by rcini＠optonline.net

Hello, all: The Altair32 project is progressing nicely. I've completed the coding, so it's feature complete *except* for the Telnet server code. The emulator now can load and save files, accept disk images (the "controller" is the standard MITS 88DSK), and produce printer output. I also modularized it a bit so that it's easier to add devices to it in the future. Obviously, the Telnet server code is key since that's what will serve as the attached terminal. So, we are unfortunately still restricted to using the FP. I have a few bells and whistles I like to add. For example, I'd like to add real Altair fan noise. Spin up. Run. Shutdown. I'd also like to change the FP to the original 8800 instead of the 8800b that was originally used. What I'd want to do is superimpose the graphic switches and LEDs over a picture of an actual 8800. The existing graphics size is 600x320, but I can make it larger if need be. I haven't posted the code to my Web site yet because I'd like to first offer it up for "beta testing" to the ClassCmp group. If anyone is interested in seeing the full source distribution including bitmaps and VC6 project files, please email me off-list and I'll send you a zip file. Just a personal reflection. Before this project, I never programmed in C, much less in "Windows." What a learning experience. I do have to say, though, that C is fairly easy to learn and use, but I'm sure that I'm only using about 20% of what C offers. And even at the end of the project, I still have trouble with pointers :-). Rich ClubWin!

Sun monitor cables

Farnell do list the coax inserts (they also stock the high-current power plugs that can be used in other 13W3 appications), and IIRC they list the 13W3 shells in two places in the catalogue (which I don't have handy). They might be out of stock, I suppose.

Electrospeed also sell Siemens inserts for DIN 41612 mixed-body connectors, which AFAIK are interchangable -- but the Siemens ones are (even) more expensive. You can also get them from RS (rswww.com) or Electromail: 485-164 RG178B/U straight plug ?4.16 485-170 RG174A/U straight plug ?4.57 485-186 RG178B/U straight socket ?4.84 485-192 RG174A/U straight socket ?3.89 You can get the cheap version from CPC (www.cpc.co.uk): CN04661 RG179B/U 75 ohm plug ?1.43 CN04662 RG178B/U 50 ohm plug ?1.43 CN04663 RG179B/U 75 ohm socket ?1.52 CN04664 RG178B/U 50 ohm socket ?1.52 You can get Sun-to-VGA adaptors (both genders), half-pitch 50 D plug (SCSI-2) to 50-pin 3-row D (which is probably what you called "weird oversized-D"), and 50-pin D to 50-pin D from Videk (www.videk.co.uk). -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Ways to bounce a 1541

by spectre＠stockholm.ptloma.edu

Well, this is more a brag than something constructive, but I wrote my first automatic Commodore 1541 disk drive re-aligner out of desperation this weekend. I couldn't get it to read any disks and since this drive was the internal 5.25" in the 128DCR, I couldn't just replace it. So I wrote a program that commanded the FDC to whack the head into the restraining rail until it could read the disk again. Voila. ;-) The things you do when you're desperate ... -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- Violence is the last refuge of the incompetent. -- Salvor Hardin -----------

SMD cabling information / Symbolics know-nothings

by red＠bears.org

Derek Peschel and I are sitting here scratching our heads making confused noises trying to figure out why my Symbolics is broken. It worked (to a point) before I moved to this new house. Now it's not working even tot hat point. Power good. We can't get the FEP booted. I wonder if I haven't gotten the SMD disk hooked up correctly? At the drive end, there ar four possibilities for where to connect the 60-pin A cable, and two possibilities for where to connect the B cable. I have a terminator. We have wasted lots of time searching the web for this informaiton. How do I hook up the drive so I know it's connected properly? It's a 760 MB CDC Sabre 9720. Help! ok r. ps. Does anybody know enough about these machines to help me troubleshoot it? I think the basic parts all work, but just not yet together. It's a Symbolics 3650.

I heard about someone who disassembled a "worst-case" memory diagnostic for some DEC machine with core, perhaps the PDP-8, perhaps some other 1960's model. He calculated that the program did not, in fact, perform a worst- case test for memory access/data loss. He described his ideas to improve the program to a Digit (DEC employee) who was familiar with the hardware and software in question. The curious customer was warned against implementing his idea because it was already known that a true worst-case scenario would result in too much current being drawn through the core stack, causing serious thermal problems if left to run for extended periods of time. Also, there were programs in the days if Big Iron to abuse hardware built with a particular duty cycle in mind, print hammers coming to mind. One I was told about by the perpetrator was simple and fiendish - he analyzed the pattern of letters on the band and devised a print line that caused all the hammers to trip at once, rather than the usual 10%-20% that fired when ordinary text was printed. The resulting current drain from a relatively small number of lines of this, fried the power supply. Then there's the practice of writing disk diagnostics that take advantage of harmonic oscillations when the drive's voice coil is slammed from inner to outer track, causing the drive to walk across the room. There are stories of this happening entirely due to heavy usage and disk thrashing, not just college pranksters seeing what the limits of physics are. Disks that weight one kg. and inkjet printers just aren't as much fun as the older stuff, one might think. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

Who wants/needs a DEC CDROM RRD42 ? (trade or free)

by claudew＠videotron.ca

Hi I dont collect DEC/VAX stuff but I have one of these here. Cant tell ya if it works. But takes the CD in and ejects, led seems to behave normally. I dont have the original caddy. Someone told me to keep it for him but have not heard from him in a very long time...I cant recall who, perhaps he will read this and put his hand up... I picked it up when I had the opportunity to empty out a VAX8350 of all its 13 boards (free for cost of shipping given away here on mailing list) Would love to make someone happy. I have no use for this. Most probably will go into garbage soon if no takers...I have idea of its value. Would accept a trade for anything micro 8-16 bits 197x-198x early 1990s that I could add to my collection.
