Believe me, I know all too well - time is probably the most valuable commodity we don't have enough of, closely followed by space... I have a PCB layout for an electronics project which I had prepared in January I think that I *still* haven't done anything with because I just haven't had any time. (Partly my own seasonal prioritising; Summer is for getting out there with camera in hand to see as much of the world as possible, Winter is for poring over dead bits of computer - at least that's what I'm trying to convince myself :-).) The offer of film was partly because it's so damn hard to get hold of professional film these days. It's a lot easier in London than out here in the provinces I think, but while it's certainly not yet unobtainium going shopping for a roll of, say, TMax 400 round here is an exercise in hope over expectation. My wife has had to come to terms with the house not only being full of computer 'junk', but the fridge also being full of rolls of film because I buy in bulk :-). Anyway, I fully understand; if you do ever find the time to take those shots, the offer is always open. >> Canon A1, an absolutely beautiful bit of kit IMHO, and I'm hoping a > > Rather too much electronics for my taste...

Thanks very much for the offer - I might just take you up on that! It's a Zorki 1b with the 'standard' Industar 50mm lens; not particularly rare, but as my first foray into rangefinders (and bottom-loaders for that matter) I didn't want something I'd be too scared to use!

Suggestions on through-hole prototyping board

by cclist＠sydex.com

Lately, all I've seen in 0.100" prototyping board is really inferior phenolic material in small sizes from China with nearly unusable pad patterns. Adhesion of the foil to the board substrate itself is chancy at best. I used to be able to get fairly good-sized (6"x10") pieces of FR4 protoboard with useful patterns (e.g. laid out for 0.300" DIP, with power traces down the middle and pads extending for 2 holes from each DIP pin) with all holes being plated-through. Short of taking old PC ISA or S-100 prototyping boards and cutting them up, does anyone know of some good sources for proto boards? Thanks, Chuck

I'm based in Leeds but travel to London pretty much every week for what it's worth. (If you didn't want to entrust negs with me - and I wouldn't blame you - I'd be happy to give you a roll or two of TMax B&W film & you can post me the exposed rolls back - I can process & scan them myself at home.) (Oh, the offer of scanning negs/slides is of course open to anyone if you need it, within reason!) As an aside, maybe a love of old cameras and classic computers is a natural fit :-). Although I do shoot digital, my favourite camera is my Canon A1, an absolutely beautiful bit of kit IMHO, and I'm hoping a 1950s Russian Zorki rangefinder is going to land in my lap before Christmas! Shameless self publicity - if anyone's curious, some of my photography is at http://www.flickr.com/photos/snowgoons/ ;-). (No classic computers there though!)

RL01 directory listings

by jwest＠classiccmp.org

Since I got the 11/34 up with one rl01 and one rl02 drive, I was able to read a stack of RL01 cartridges that came with the 11/34 as well as a few others that I got from other sources. In case there is something wonderfully interesting on them that anyone has been looking for, I posted a directory listing of all the RL01 packs at the following URL: http://www.ezwind.net/jwest/RL01DISKS.txt If anyone wants any of the files, just let me know off list. Once I check with the previous owners to make sure that file isn't personal, anyone is welcome to a copy. One of the cartridges has MPPascal. I am not sure if this is MicroPower? Pascal or if it's a variant of OSI Pascal-2? I do also have OSI Pascal-2 v2.1F on RX02 floppies. I also came accross an RX01 floppy that contains the source code for the RT11 driver and bootstrap for the COI Linktape II. One of my RL01 packs contains XXDP diagnostics, and it is a different version than the 2 verions I've seen available on the net. In addition, I have an RL02 pack that has diagnostics that are older than most I've seen around. I believe I listed both in the online directory listing. Another question - if under RT11 5.04, a disk pack shows "invalid directory"... doesn't that rule out RSX and RSTS packs? In other words, aren't those directories at least visible to RT11? I'm wondering what I can assume if a pack shows invalid directory under RT11 and isn't bootable with regards to the likelyhood I can consider it a scratch pack. I'd rather not init a pack that may contain something. Is there a better way to look? Jay

MMJ cable length?

by tothwolf＠concentric.net

I was thinking about putting together some standard MMJ cables, but I realized I didn't know what the standard lengths were. Can anyone tell me which were the most common/useful lengths for the original DEC cables? I've seen and use cables as short as 18" and as long as 50ft. I've used a lot of them that were somewhere in the 12-15ft range, but I'm not sure what length would be the most versatile. -Toth

OT - 486 w/newer IDE drives

by chrism3667＠yahoo.com

Got this barebones 486 mobo. I'm trying to setup a 20 gig Fujitsu MPG3204AH drive. Types 1-46...then there's 47. I'm looking for the parameters as I type this. Has anyone accomplished this? What about a newer cd-rom drive? I don't have any 3.5" drives at my location, but I know that somewhere I have a Win98SE boot cd (I made it). Don't think I have any 5.25" boot floppies either. I'm a mess! Trying to get some images burned onto floppies, so I can play :). I doubt I can get this working today. I did make that hard drive bootable some time ago, but the P166MMX unit wouldn't boot from it. I don't have a clue. If anyone can call me, that would be great LOL! 8016260<area code 732>. I can't get my dialup stuph working, and I had to drive to a nearby hotspot w/my laptop just to do this! Man am I a mess. Can't find a 3.5 anywhere in my stash. That would make everything work.

Amstrad's PCs

by chrism3667＠yahoo.com

not the one with the "pop-up" lcd, but didn't Amstrad make a Atari ST-looking model (essentially a whole computer in the keyboard) with presumably an 8088? Can't find it on old-computers.com. Not much but the above mentioned PPC-640 shows up in an casual google search. Actually maybe it had an 8086. Actually maybe the thing I forgot to bid on (a long time ago) didn't have an Intel proc at all, and the auction lied or was misinformed. Though off the subject, I'm desirous of obtaining the Franklin PC 5000, 6000, 8000, you know that tawdry looking brown peecee thing.

PC20 / PC200

by alhartman＠yahoo.com

There is also another "all in one" PC Clone similar to these two machines, though not as nice looking... VTech, the manufacturer of the Laser 128 series of Apple Clones also made several PC Clones. One of them was the Laser 512XT. I have one of them. I'm missing the Power Supply for it, so I don't know if it works. I haven't been able to find one on eBay or anywhere else. It's funny that the PC20 / PC200 was meant to compete with the Atari ST, since Atari also made several PC clones. Every company did, even Commodore at the time. I think my favorite PC Clone was the first one I've ever used, the Columbia MPC. Though I've used several PC Clones over the years: I liked the Mindset too. Although I don't have one of those. Al

Hard Sector Diskettes, was Re: Northstar Horizon

by marvin＠rain.org

A couple of questions pop up on this Northstar diskette discussion. First, was the oersted rating the same for all of the N* Horizon (and Advantage?) diskettes? And to expand it a bit, what about other hard sectored diskettes ... Heathkit, Vector Graphic, etc. And what about the 8" floppies? My knowledge in this area is nil and I don't recall ever having read anything. Second, it seems to me that someone has already made a punch for modifying soft-sectored floppies to hard sectors. As Tony says, it shouldn't be hard to do. As such, would there be much of a demand for such punches? > On 25 Nov 2006 at 13:34, woodelf wrote: > > > Can't one make a punch template and punch out the holes needed? > > Ok you have to kill a few disks in the process for the sleave and > > floppy part. > > The envelope wouldn't matter--you can usually reuse those. > > I suppose you could punch some diskettes, but soft-sectored diskettes > are still pretty easy to get. > > Cheers, > Chuck

Double Punching Diskettes

by alhartman＠yahoo.com

For 5.25" Diskettes, a friend made me a template by taking a piece of plexiglass and punching the holes as a guide in it. I used that template to mark the disk with a silver pencil (not a lead pencil, but a coloring pencil with some wax in it) and then used a regular hole punch to make the holes. Another friend had a metal template made from some thin metal that was bent over so that a disk could be inserted into it, the holes marked with a silver pencil and then punched using a hole punch. I rarely had a DDSS diskette fail on either side. And never had a DSDD disk fail. Though I usually bought Verbatim, Maxell, Elephant or Wabash disks. Even BASF floppies were ok. Though BASF Floppy drives were AWFUL. I did (and do now) have a Wangtek Flippy Drive with the Percom label on it. This drive didn't need extra holes punched since it had two sets of sensors mounted in the drive. You just flipped the disk over and it worked. I'm amazed that I used to think paying $30 for 10 180k diskettes was a bargain... Al Phila, PA

Northstar Horizon

by river＠zip.com.au

Hi, Thanks for the replies. I've probably seen some of the web sites mentioned as I have downloaded various manuals and documentation for the system. The processor board has the provision for 1K EPROM, which isn't installed. I'd assume it's for a 2708 device. Unfortunately I cannot program these devices, so I can program a 2716 and do some mods to the processor card to make the 2716 work and show only the 1st 1kbyte. In my spares I have a few Dynabyte and Microbyte RAM cards (both static and dynamic), an old MITS 8800B CPU card (which needs some serious TLC), a spare ZPB processor card, some weird S-100 Inc 4K EPROM card which looks like it can take 8 x 512byte, or 4 x 1k or 2 x 2k EPROMS, a Vector Graphics ZCB processor card, and a few S-100 blank prototyping cards and a 4-slot S-100 mainboard. I can wire-wrap up one of the proto boards as an EPROM card if I need more and run the DOS all in silicon, if this is possible. So, if push comes to shove I can modify and use one of my 8080/85 debug/monitors and let it run on the Northstar. I guess the hardest part is getting a set of drives that will run on the AD3 card, along with the necessary diskettes. I rechecked the disk controller card and it is clearly labelled "Micro Disk Controller MDS-AD3", which makes it the double-density diskette controller. I do have another disk controller card, by Delta Products, that has a 1791 FD controller chip on it, but I have no doco for this board. However, the first thing I need to do is clean-up the system, blow out the dust, fix the blown caps and then go through the downloaded documentation that describes how to test/verify the various boards are operational. Again, thanks for you replies and I'm going to join them into a single document for reference and also go to the various links you have supplied to see if I can get more information. regards river
