>I like the C16 since it has the BASIC and simple Assembler in the Monitor that the C64 should have had from the beginning. TED also has a few features VIC doesn't (hardware cursor, >hardware reverse, full 64K access, colors, programmable counters for horizontal and vertical position). We were accused by the head of CBM England of having made the TED the perfect machine for pirating software. We telexed back a simple "thank you". I spoke to her for the first time face to face just last summer and made sure that there were no hard feelings about my continuing to tell the story. She was gracious in the ways that we are all part of a 30 year old (dysfunctional) family are. > - Add heatsinks to CPU, TED and PLA > Again product life wasn't never a consideration that I found >Yes... back then, but to keep them running now, getting as much heat off the die is a good thing. I used to know the temperature we were running the die at, if I could have save $.25 by running it 5 degrees C hotter I probably would have as that was the incentive. With that said my background previously had been instrumentation and there we lived by an industrial MTBF. >I'm also surprised how they hold up.

Especially VIC runs quite hot >but doesn't seem to care. Then there are the PLA, SID and 8501 and 8360. :( Once we got the passivation problem fixed, which was especially bad on early PLA's then we were back to more standard aging mechanisms, (heat, heat cycle stress, etc) The Rev 7 VIC was the first to use a Beryllium Copper Lead Frame to get the heat out, so the outside would be hotter and the inside would be sparkling less. > CBM did realize they needed to get into CMOS and had broken ground on the > new line when I left. I was told they never finished . MOS did some CMOS chips, the ones I know are: >5710 found in C128DCR, simplified CIA >5717 Mouse 1351 >5718 Gate Array on bridge boards (A2088/...) >5719 GARY (Amiga 500/2000B) >5721 BUSTER (Amiga 2000B) >I don't know if MOS made them or had them made and just stamped their >number on the package. We were definitely purchasing CMOS gate arrays for the LCD machine, (someone found the missing wafers sitting in a carrier on a manger's desk being used as a paperweight), and CBM was transitioning to full ERC/DRC based tools and some outlandish autorouters for the gate arrays (compared to carefully crafted layouts) that we were sourcing. I remember Kyocera packaged them but I don't remember if they were also the chip fab for the CMOS. Meanwhile the drawers still held rubylith and the punch card reader was in a corner of the hallway. The LCD also got to break some of the rules for cost at least initially for where to purchase parts, but then was using our own LCD glass from Eagle Pitcher which we owned (Only US glass at the time) >I read about that...

Sometimes a Telex or phone call actually seem to make the problem worse (there was a fair amount of "don't tell me how to run my office" in the different segments) Going there in person helped a lot, especially when some of us learned how to curse in Japanese. One time it almost backfired, they wouldn't arrange for me to come back to West Chester so I could finish a release, I had to have the West Chester office buy my tickets and have them delivered to me personally for me to "escape". That was the only time I didn't have to carry 80 pounds of parts with me on the plane. Message was sent through the cbm-hackers mailing listReceived on 2013-05-02 17:00:44
