That's an interesting list, and I'm sure that it will help narrow things down some, but I can't recall from just the title which article it was. The list will help me omit some of them, though. A while back I did a serious reduction in a lot of the old magazines that I had been keeping, and included in that was a bunch of Byte, not the real early ones, which I still have intact, but that period of time when they started to get rather bulky. I clipped a lot of articles out and kept them, and filled nine large trash bags with what I didnt want any more. Somewhere around here I have a couple of boxes that have those clipped articles in them, and once I find them and get the chance to go through them, I'll probably find the article I'm thinking of. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be tamed. ?--Robert A.

Keyboard PS/2 to Parallel converter

I've built up hand-wired prototypes, but I have not laid out a PCB. The schematic is just an 8051 with power/crystal attached, or an 8031 with external ROM and address latch as per any 8051/8031 datasheet. The PC keyboard clock and data lines are attached to the pins indicated in the comments in my code. If you want RS-232 levels, you need a level convertor (MAX232 etc.) on the 8051/31 RX/TX signals. > And have you an idea to how to transform the circuit from serial to > parallel? Instead of polling for TX ready and writing the scancode to SBUF, just write it to P1 (8-bit parallel output). You will also need a key-down strobe, which you can implement via another pin, using key-down scancodes to set, and key-up scancodes to clear. Assuming you want ASCII instead of scancodes, you would need a translate table (scancode to ASCII), and to recognize and track the state of the SHIFT, CTRL keys and CAPS-LOCK state, either using alternate translate tables (most flexible), or modifying the codes from one table accordingly. Implementing rollover properly requires a bit more logic - once you have processed a key-down, you must queue any other scancodes you receive until you get the corresponding key-up, then process the queued codes after you have released the strobe. You can get fancier, implementing auto-repeat etc. if you like, the logic is pretty straightforward (if key-down persists beyond the initial delay, begin toggling the strobe at the repeat rate).

Who's collection is that?

by mike＠brickfieldspark.org

Its the collection at Bletchley Park, the WW2 codebreaking site http://www.bletchleypark.org.uk/edu/collect/computer.rhtm Enigma, Bombe, Colossus and all that. I need to get down there sometime and drool over the Elliott 803. Jeremy Clarkson dos the BBC2 Top Gear motoring program, used to be a serious motoring program but in recent years has turned into a "boys toys lets see what stupid thing we can do with a car" program, funny all the same, a bit of light relief. I'm very surprised Bletchley Park let him near those machines, the BBC must have had to agree to serious contractual terms, Clarkson's comments are always controversial and he is renown for breaking things, especially that involving technology. I have to say I do agree with him sometimes.

Who's collection is that?

Ah you underestimate the power of TV. They would have of course been insured. If they thought it would make good TV they could have copied the room onto a set, bought up old systems and had him trash the lot!

Keyboard PS/2 to Parallel converter

One Atmel Mega8 (or a Tiny24 would work, though I don't have any here to test the code). Is there something else you're looking for? I modified the PS2Encoder design on the web site (http://www.jbrain.com/vicug/gallery/PS2Encoder) to offer a truly generic one (all data lines come to a 2x13 header, and the PS/2 connector is already on the board.) I know the design works, as I tested the code before I sent someone on the list a version for a FlashWriter II KB interface. > Holger, > > it's exactly what i'm looking for.

My code will work, and outputs 41H when a A is sent (Actually, I think it sends lowercase a, but I can change the mappings in a few minutes if that's an issue) Holger is speaking theoretically, without any specific design in mind, I believe.

Keyboard PS/2 to Parallel converter

by elazzerini＠interfree.it

Hi at all, as many will have understood, i'd like to make my BigBoard 1 alive again. I need for a ASCII parallel keyboard. Many years ago (exactly 20 ones) I got a old cherry keyboard; I open it and rebuilt all its rows and colums to be the inputs for a KR-2376 keyboard encoder. I had much more time.. I though to realize an economical interface to convert signal coming from a PS/2 keyboard and convert each codes in parallel standard (data 0 to 7 plus strobe signal). Here there is a schematic already suggested http://eece.ksu.edu/~eece696/beta/digital/A/stop.htm but could it works? What could be the exact schematic and hardware to use? And at the last is there anything "ready-to-use" cause I have not much time to spend to build it? Thanks to all will answer. Regards Enrico

Wonder how useful this would be, MMC to floppy disk adapter

Sale Price $9.99 Dunno, but at that price, I couldn't resist ordering a couple. I'll pop one open to see what makes it tick. Note that the floppy is simply used as a coupling device--the gizmo requires installation of drivers. I'm particularly interested to see if those drivers will work with a USB drive (i.e. how general are they?)--the literature's not quite clear on that; only that it doesn't work with PC Card drives. Thanks for the link. The Smartdisk.com web site doesn't seem to be responding; let's hope it's temporary. Cheers, Chuck
