Hi All -

Does anyone know of a repair shop in the SF bay area that can help me fix my EIII Rack?
I need a new internal HD (preferable flash drive) and an OS v2.42 floppy disk.

Thanks for any replies,
David Willenbrink

Got the VU meter working! Found a cut trace on the Output board from R46 to R40. In case anyone else is having issues with the VU meter check the circuit at the very bottom of the schematic page for the Emulator 2 Output - Input Analog 7-42 (page 4 of 15).

Now on to my final issue... noisy samples. This started a couple weeks ago. Any audio fed into the machine sounds clean through the monitor but after it has been sampled / upon playback the sample sounds very noisy - almost static-y. It's not a RAM memory sound issue and the input is not being overdriven...

Even when nothing is plugged into the input jack and I sample 'nothing' there is quite a loud digital noise floor that is being sampled... maybe a bad capacitor issue?

Yet again...  I think my mod for new displays may fix a lot of these issues.....

This is actually a common issue which I've reported a fix I came up with before but perhaps not on this site.

The LCD timing on the EII is marginal and although it just about works with older HD44780 compliant LCD modules, many of the modern equivalents have faster timings. 

This often manifests itself by showing nothing, a solid bar or garbled characters on the bottom line of the display.  The top line is always fine with a new display fitted.

The fix I came up with several years ago has helped a number of other owners to make their new displays work so this is definitely worth a try....

FIX: Solder 4.7NF metal film capacitor between pin 1 (Ground) and pin 6 (Module Enable) on the LCD module header.

This works by slightly lengthening the Enable pulse to the display.

Sorry, the midas screen is always mad

Might be worth trying my usual mod for new displays on EII....  (I'm not saying it will work in your case but its worth a try)

*UPDATE!*

I was able to solve the problem "ALL RED LEDS ON"...

Man. There was a screw stuck under the Emulator motherboard!!!!!

Must have been there for years, from the previous owner.
The screw was not belonging to the Emulator II.
There must have been a contact between the external case and the board, thus the leds on!

Concerning the problem about the strange characters on the display...

The problem appears when I am using the Emulator for some hours, when it starts to get hot  Grin
In case I have to switch it off and then on, the strange chars starts to populate the display.

Then I switch it off again, pull off the power cable.
I wait for 1 minute, then I put on the power cable again and power-on the Emulator.
The problem is gone.  Huh

Any clue?
Thanks for your help guys

Andy
