Re: Lexicomp Gradebook (EGS) 2000

One other question - do you have power adapters for the EGS 2000, LC-8600, and LC-8620? What are the specs? Center-positive, 5VDC, 1A? What are the inner and outer diameters of the jack? I tried a 5V, 2.5A, center-positive supply, but the machine failed to turn on. Perhaps it has the wrong jack size...

Re: Lexicomp Gradebook (EGS) 2000

Photos - yeah something like imgur or so would do I guess. I had a public image uploader here long ago but since people abused it with....questionable pics...I kinda ran into trouble with my hoster. No problem. Here are the pictures on Imgur: https://imgur.com/gallery/RmzK9kZ My buddy has no idea a...

Re: Lexicomp Gradebook (EGS) 2000

Sorry for the late reply, was a very stressful week so far.... Sorry, can't see any of your photos. I see they are links to googlecontent but even when I copy them into another browser it won't show anything. That's strange! I can see all of them fine, but then again I am the source of the photos (...

Re: Lexicomp Gradebook (EGS) 2000

My machine is missing serial/parallel and battery covers (see below). I checked with the vintage computer enthusiast friend who gave me this to see if he accidentally misplaced these covers, as the eBay listings suggest the palmtops included them. If he never got these pieces, it would be great if ...

Re: Lexicomp Gradebook (EGS) 2000

I just tried using 32MB and 1GB CF cards in my Gradebook 2000 and failed. It seems sdpdrv.sys is not activated in config.sys on the C (ROM) drive (rem device=sdpdrv.sys). How can I use an alternative config.sys/autoexec.bat (with sdpdrv.sys activated)? There doesn't seem to be a RAM drive boot optio...

Re: Lexicomp Gradebook (EGS) 2000

OK, I finally got the machine! The construction is quite impressive and satisfying. The screen is simply delightful relative to every other small DOS machine I have, except my now "dead" Fujitsu Poqet PC Plus (bad hinge). My machine is missing serial/parallel and battery covers (see below). I checke...

Re: Lexicomp Gradebook (EGS) 2000

OK, good to know! I posted links as you saw in the other post. It would be nice to experiment with EPROM, but I'm not going to push it. I'll at least post photos of what I find. Regarding power management, do you know of any DOS utilities that could further improve it? Maybe power.exe from MS-DOS 6....

HP 95LX tips and vids

Hi all! I just wanted to share my recent findings about the HP 95LX as I thought you all would appreciate them. I have been able to get CF cards to work in the 95LX, following directions here: https://hermocom.com/hplx/view-all-hp-palmtop-articles/41-95lx#storage. You can use up to 32 Mb cards given...

Re: Lexicomp Gradebook (EGS) 2000

I'm already curious how you will like the Gradebook. Unfortunately time didn't preserve many of these devices, even less accesories and barely any information. Keep in mind these are from a time when the internet was not really common. Your gradebook is the 2nd one in the world I ever learned of - ...

Re: Lexicomp Gradebook (EGS) 2000

Well if you boot from PCMCIA I don't really see the need for RAMDisk, I mean 1 GB storage is already a lot. Does yours also have 2MB of RAM? Not sure but I thought they might also have sold these devices with 1 MB of RAM. Given the nature of the Gradebook software I fail to see how they utilized th...
