没有什么不寻常的,但8591A中的备用电池已经死了。
如果它是8590A,我将能够遵循新的启动程序,该程序始终包括以“RESET”开头,然后是键盘输入。 8591A显然是不同的,因为当我触摸“RESET”时,显示屏会进入CRT无用数据的暴风雪。 重新启动不需要重置的8591A有什么特别之处吗? 我错过了什么吗? 以上来自于谷歌翻译 以下为原文 Nothing unusual but the back-up battery in my 8591A went dead. If it were an 8590A, I would be able to follow the new start-up procedure which always includes starting with "RESET" followed by keyboard entries. The 8591A apparently is different as when I touch the "RESET", the display goes into a blizzard of useless data flowing across the CRT. Is there something special about rebooting an 8591A that doesn't require a RESET? Am I missing something? |

嗨stateasylum,这听起来像是按Preset将默认水平位置DAC设置为超出crt监控电路可以锁定的值。
在这种状态下,由于失去水平同步,光栅扫描显得模糊或歪斜,并且通常是不可读的。 要恢复水平锁定,您需要导航到HORIZ POSITION软键,使用前面板上的旋钮或向上/向下按钮来改变DAC。 或者,有一个LOAD DEFAULTS软键可以恢复合理的设置。 这里的catch-22是你无法在这个解锁状态下看到软键标签! 因此,您需要一个键盘图来指导您完成按钮按下。 我现在没有一个方便(在用户或服务指南中应该有一个,可能在线),但如果你可以等,我明天会添加回复:)问候,Simon Coleby。 以上来自于谷歌翻译 以下为原文 Hi stateasylum, This sounds like pressing Preset is setting the default horizontal position DAC to something beyond which the crt monitor circuit can lock to. In this state, with a loss of horizontal synch, the raster scan appears smeared or skewed and typically unreadable. To restore horizontal lock you need to navigate to the HORIZ POSITION softkey to vary the DAC with the knob or Up/Down buttons, from the front panel. Alternately, there is a LOAD DEFAULTS softkey that restores sensible settings. The catch-22 here is that you can't see the softkey labels in this unlocked state! So, you need a keymap to guide you through the button presses. I don't have one handy right now (there should be one in the User or Service Guide, possibly online), but I will add a reply tomorrow, if you can wait :) Regards, Simon Coleby. |

谢谢,西蒙。
我会试一试,让你知道结果如何。 直到星期天我都没有时间玩它。 皮特 以上来自于谷歌翻译 以下为原文 Thanks, Simon. I'll give it a try and will let you know how it turns out. I won't have time to play with it until Sunday. Pete |
