looking for some Kennedy 9100 boards

by henk.gooijen＠hotmail.com

Hi, I know it's a long shot ... I am looking for the data terminator card and the control terminator card of a Kennedy 9100 tape drive. According to the doc, these small boards are also used in the Kennedy 9000. They are missing in my 9100. Thanks! Henk.

MZOS ROM

by lynchaj＠yahoo.com

Hi Does anyone have an early model Vector Graphic computer with the MZOS ROM in it? It would be an early Vector Graphic computer (pre-1980) with 48K RAM. The MZOS ROM would be located at $C400-$C7FF. Even a hex dump from DDT would be useful or any other format I can convert. I need the MZOS ROM to be able to compute the sector checksum on some MZOS boot disks. Those disks are not readable with my VG machine or CWVG since they use a unique checksum algorithm. Actually, I can read the disks with CWVG but I cannot verify the contents of the sector with the checksum so I have no idea if the data is actually good or not. Thanks! Andrew Lynch

A note on Keyboard interfaces

by brain＠jbrain.com

For those with machines that have a way to plug into the KB matrix and want PS/2 keyboard support, I would suggest a derivative of C=Key (www.jbrain.com/vicug/gallery/c=key/). It acts like an 8x12 keyboard matrix to a vintage machine, no modifications to the machine are needed. As currently laid out, it's designed to work with the CBM VIC/64/128 series machines, but the source has been structured to allow easy retargeting to any KB matrix up to 8x12. On the PS/2 side, it decodes all incoming data and can send data to the PS/2 keyboard, such as resetting the KB and setting indicator LEDs. And, source code is under GPL, as is the design. I'm always up for a donation if you like the work, but I was once a starving collector too. The key is the MT8812 (or equivalent) cross point switch. However, it's overkill if you just need a serial or parallel output (PS2Encoder is much simpler). Note that, if you just need a PS2 KB to vintage machine interface, C=Key can be reduced in size and a much smaller uC can be used (you only need 8 data lines to run the Xpoint switch, 2 for the PS/2 interface, so a 14 pin or 20 pin uC will work fine. That's the same for the PS2Encoder. I used a 28 pin IC in the design as that was handy, but the design can work the smaller units. I'd be happy to help folks design new variations on the design for other systems (Atari and TI come to mind). Jim

Who's collection is that?

by feldman.r＠comcast.net

It seems Clarkson does not know that much about modern computers either. The following is from the latest SANS Newsbites. <Quote> --UK TV Host Learns a Lesson About Data Exposure (January 7 & 8, 2008)UK television personality Jeremy Clarkson put his money where his mouth is and lost GBP 500 (US $984). Clarkson published his bank account information to demonstrate that the media frenzy over lost HMRC data belonging to 25 million people was unwarranted. Clarkson was certain that no money could be transferred out of his account. However, one reader managed to set up a GBP 500 direct debit to a UK charity. Because of the Data Protection Act, there is no way for the bank to discover whoe stablished the direct debit, nor is there a way to ensure that it doesn't happen again. Clarkson has admitted he was wrong about the potential risks inherent in data exposure. http://news.bbc.co.uk/2/hi/entertainment/7174760.stmhttp://www.sunderlandec… </Quote> Message: 9 Date: Wed, 9 Jan 2008 09:38:08 -0000 From: "Mike Hatch" <mike at brickfieldspark.org> Subject: Re: Re: Who's collection is that?

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).

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

OK, someone beat me to it (or saved me the trouble of scanning, not sure which :-) on the CDC manual. Hrm. Did someone scan and contribute to bitsavers and then sell it to me on ebay? <http://bitsavers.org/pdf/cdc/graphics/grid/PD82134500_GRID_Preliminary_Hard…> -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

S/360 update

by ljw-cctech＠ljw.me.uk

I've just had a email from Bob Doran, who was one of my CompSci professors at Auckland University. It seems that they (AU Comp Sci) have the front panel from my 360 which they salvaged many years ago, and which is now becoming part of a lobby display. So at least now I know something about what happened to it, but I suspect that the rest of the system was scrapped. One part he's after for the panel is the centre Display Store Selection rotary switch dials (there are two parts to the rotary switch), so if anyone happens to know where there's a spare one, I'm sure he'd be grateful! (See the top picture at http://www.corestore.org/360.htm , thanks Mike!) -- Lawrence Wilkinson lawrence at ljw.me.uk The IBM 360/30 page http://www.ljw.me.uk/ibm360

Keyboard PS/2 to Parallel converter

by elazzerini＠interfree.it

I report each part of different emails whit my question: From: "Roy J. Tellason" <rtellason at verizon.net> There was some project article in Byte way back when, by Steve Ciarcia, which provided a peecee-type keyboard input (AT rather than PS/2 but that shouldn't make that much difference). The circuit to deal with this was very simple and elegant, though I can't remember any more just how it was done. He didn't use a UART or similar, though, just a couple of MSI chips. And I remember thinking then how it wouldn't be all that hard to stuff an eprom between the output of that circuit (which gave you keycodes rather than characters) and have it spit out ASCII. Perhaps one of these days I'll run across the article again. Roy, here would be the list of articles by Steve Ciarcia http://www.devili.iki.fi/library/author/203.en.html May you try to find the exact article? Enrico From: "Dave Dunfield" <dave06a at dunfield.com> If anyone is interested, I have a very small bit of 8051 code which reads an attached PC keyboard, providing the scan codes over an RS-232 link. It also supports commands to set LEDs on/off etc. I specifically avoided using the P1 line in my design (full 8-bits parallel I/O available even on an 8031), so these are free, making it very trivial to modify this to output parallel instead of serial - it would also be very easy to add a translate table and recognition of shift/ctrl modifiers so that it would output fully decided ASCII. Dave , have you just the code or even the circuit PCB layout? And have you an idea to how to transform the circuit from serial to parallel? Enrico From: Jim Brain <brain at jbrain.com> If you didn't care about sending codes back to the keyboard, then you'd just need an 11 bit shift register. The previously mentioned <http://eece.ksu.edu/~eece696/beta/digital/A/stop.htm> http://eece.ksu.edu/~eece696/beta/digital/A/stop.htm is almost there, it just needs 1 more F/F 2 LS174s would work for the F/Fs. the CLK line needs to be inverted, but you can probably get away without doing it. A divide by 11 counter (LS163 with and AND on bit 0,1 and 3 driving CLR) should do the trick. Jim, i need just this, I don't care to see the caps lock led turning on or off!! But the schematic indicated to that link, it appear to be a theoric schematic. I really have not time to testing circuit or verify how it works. So anybody has an idea of a pratical circuit working? Thanks Enrico From: Holger Veit <holger.veit at iais.fraunhofer.de> No, I am not yet at a point to use a microcontroller just to blink a LED, which have been done with two cross coupled transistors in the past, but a PIC is meanwhile the more compact, easier, more flexible solution to "convert-from-A-to-B" problems. Holger, it's exactly what i'm looking for. So may you give your help? What PIC to use? I have a PS2 Keyboard and when I press the character A I need to have the binary code 41H that means 0100 0001B on eight wires plus a strobe line. Only in this direction. Is it possible? Thanks Enrico
