Hi Tony (and list), > Why do you suspect they're faulty (or why do you want to > replace them).

Yup; certainly all of the broken ones were between +5V and GND and I got them swapped over last night - 104Z 50V ones 'cos I found a parking space just round the corner from the shop on my way home, and I got 12 english pence back too :) This brings to mind a separate question that I'll post in a bit. cheers! a

"Locking Connector Kits" for LocalTalk

by mythtech＠Mac.com

>Not necessarily; the C64's video port comes in an 8-pin variety and they >call that DIN-8 also. Much larger, however, than Mac Mini-DIN. I meant isn't the Mac din size (the one I thought you were refering to since you were talking about building an adaptor for a mac telenet connector), isn't THAT a mini-din. I always thought the mac serial size (as well as things like ADB, PS/2, S-Video...) were Mini-Din, and things like MIDI, AT Keyboards, stuff like that was just plain DIN. It always made sense to me, since the two styles are very different in overall size... but then, I always thought a D shell 9 pin connector, as found on things like the Mac Plus mouse port, was a DB-9, where it is really a DE-9... so maybe the mini vs large dins have two different names too. I am fairly sure MCM also sells female DIN connectors in various pin counts, as well as the mini-din ones. -chris <http://www.mythtech.net>

eMag Solutions LLC announces end of life plan for open reel (9-track) tape

by bill_r＠inetnebr.com

Maybe this has already gone through the list. If not, I thought it might be of interest. Seems like the end of an era... http://www.emaglink.com/Articles/17Dec01.htm Atlanta (December 17, 2001) - eMag, the last manufacturer of open reel (9-track) tape, is announcing its end of life program for users of this product. eMag, which has produced open reel (9-track) tape in its Graham, Texas facility for over 30 years, has determined that the significantly decreased demand for this once dominant magnetic media format mandates an organized end of life announcement and program. To provide an orderly and seamless transition for users of open reel (9-track) tape technology, we have spent over 3 years developing alternative solutions that have proven to be both operationally efficient and cost effective. For a more detailed description of eMag's alternatives please visit 9-track Retirement. Final Orders In order to properly prepare for our final build of this product, eMag will review and accept final orders for open reel (9-track) tape now, and through January 14, 2002. We will prioritize shipments for firm non-cancelable orders, on a first come first served basis, consistent with our existing inventory and final manufacturing run and plant capacity. eMag will not manufacture new open reel (9-track) tape after these final orders are completed. To assist you with your needs and answer any questions, eMag has designated experienced program managers in the United States and Europe to oversee this end of life program.

If you need to drive logic with CMOS input levels you could run into difficulty. Pull-up resistors may be required. I couldn't drive logic level mosfets and some Analog Devices parts with MAX3064 using 3V3 supply. The 'byteblaster' parallel port JTAG programmer can be a bit erratic. I had to decouple some of the JTAG signal lines with 47pF caps to make it work. Atmel's free software is really easy to use once you get used to it. Also, don't forget to tie un-used input pins to ground or Vcc. Because I was never happy with Atmel's MAX3000 output stage I switched over to using Xilinx Coolrunner. The Xilinx parts have a true complimentary output stage and you get proper rail to rail drive levels, they're also lower power too. On the downside, you have to buy a Xilinx JTAG programmer and their software leaves a great deal to be desired. Good luck Chris

WTB: Tandy items

by jhellige＠earthlink.net

I was wondering if anyone might have any of the following Tandy catalog numbered items in their piles: TV/Joystick board (26-5142) Vianet networking board (26-1220 or 26-1221) DCS interface kit/board (26-5147) All of these boards are for the Model 2000 and have the 96pin euroconnector. The DCS is the interface board for the early Iomega Bernoulli drives. Truth be told, I wouldn't be picky if someone had anything related to the Model 2000 to offer up!

PC Gamer, best 50 classic games issue?

by DAW＠yalepress3.unipress.yale.edu

! From: Mike Ford [mailto:mikeford@socal.rr.com] ! ! ! A few years ago just at the end of the BBS era, a new little software ! company came out with a Terminal package for the Mac that ! used their own ! serial port driver. I can't remember the name, but they ! buffered the port ! with some fairly nice code that ran I think during the "VBL" ! of the video ! interrupt. Not only was the throughput great, no gliches, but ! the big demo ! thing was to format a floppy during the downloading of a file. Market ! window was bad though, and I don't think they lasted even a year. Does anyone remember what this software package name is? Sounds like something I'd like to have & use... --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818

Hello, all: Well, I'm picking up the 6502 SBC project that I started last year. To reduce chip count I'd like to use Atmel PLDs for address decoding. I downloaded some app notes from Atmel's web site but are there any practical tips for using/programming these devices for use in a hobbyist project? Rich ========================== Richard A.
