Oh, and I did end up getting my hands on a small EL panel. Like 4 inches and low resolution, but hey, it was actually free. :)

Very interested.

Definitely use a resistor if you are going to try it. Reading a bit further into the datasheet, it states this is only an output, so it may do nothing. I am not seeing an easy way to hold the chip in reset without the reset pin being enabled in the fuses. It is based on an 8051, so this means...

I just looked through the datasheet and it looks like the default function of pin 14 is not reset, so holding it low during power on would not work. This is the datasheet: https://www.stcmicro.com/datasheet/STC8G-en.pdf

That is an interesting effect. That is an input to one of the ADCs. It is used to measure the battery voltage. I am surprised it caused constant key presses. Based on the datasheet for the part I think it is, pin 14 is the RST line, but it can also be configured for GPIO. It is connected to the...

My understanding (which is not 100%) is that the DOC chip works like EMS memory. There are no IOW or IOR lines to it, just the mem lines. I am currently using it in the ISA ROM card from Texelec. My understanding is that there are just two modes. Either forced first drive (C) or the mode where...

Great job on the external display test. How are you liking it? Was it worth it to do? I have received the ISP tool for the KB processor, but need to find the time to get it wired up and see if I can download the firmware from it.

It also seems to be proof that it can in fact do 15Khz since in the version 1, it is connected directly to the 6545 CRT controller and displaying CGA. The version 1 has an actual 6545 in it, not emulated in a CPLD.

I was talking about on the V1. I have both. I have not opened the V2 at all yet, but doubtful it has the connector.

While the Book8088 is on my list of projects right now, it is not at the very top. But I do have an ISP programmer coming for the keyboard microcontroller in the hopes of dumping it. I should already have all the tools needed to talk to the RTD2662 LCD controller, but have not had experience...

I have one of these coming any day now. After reading more about it, it appears to be only one or the other, not both.

Did you use primer? That should have smoothed out the surface

Probably a long shot, but does anyone have or is able to locate a user manual for the Husky Hunter 16 portable computer?

It does, but I have not experienced that particular issue with the version 2. This is more like either the bezel is cutting off some of the LCD or somehow the image is scaled overall just a few pixels too much. The overscan happens on all sides of the image. With the old version, it would only...

100% agree. I am not sure where the source of the claim originated from. I have not stumbled on the origin. Simon the Sorcerer requires a VGA card to run and it is running, so I do not have any doubts myself that VGA works correctly. The only drawback I have found is that when in VGA mode, a...
