Re: [vcf-midatlantic] November Workshop/Hack-a-Thon at InfoAge
Good evening, I plan to make some adjustments to my Commodore 1702 monitor while it is actively on in an effort to calibrate the image geometry/stretch/XY. I have a set of metal screwdrivers with plastic handles on hand, however I question the safety of using these when making adjustments while the monitor is plugged in. Would anyone happen to have any ceramic/plastic screwdrivers (flat head/Philips) with precision tips to adjust the pots inside they could bring along for the workshop this Saturday? Support in this project would be greatly appreciated if some tools could be offered then by any participants. If no one seems to have any, I could either wing it with what I have or overnight order something online for Saturday. Thanks!

Good afternoon,
I plan on attending the workshop in Wall this coming Saturday to adjust the geometry on my Commodore 1702. My plan is to use the monitor to run modern 8/16 bit games on the CRT for a classic feel. In plugging it into my PC (HDMI > S-Video > Luma/Chroma), I've noticed that the image on the screen extends beyond the frame, therefore losing about 10% of the image off-screen. Upon watching some videos on how to work on the monitor to make adjustments, I see that I would benefit from having a device that could load the 240p Test Suite software to confirm the physical calibrations I make. Unfortunately, I do not happen to have a device that can run this software and push 240p. This might be a big ask; does anyone happen to have a device that I could plug the monitor into that can run this software? Any support in this matter would be greatly appreciated!

Eric You are correct to be cautious when using a metal screwdriver in any television or monitor, especially when plugged in and turned on! I’ve been working with Electronics for 40+ years, televisions especially, I can be honest in saying that, unless you know exactly what you’re doing, I suggest you use the correct tools. Which means: use plastic or ceramic, plastic is usually better. The proper tool for the job of course is always best. Please don’t rely on people telling you to use a metal screwdriver to adjust anything inside of any operating monitor or TV, ESPECIALLY if you are new, green, and not knowing exactly what you’re doing. Asking for help is definitely the right thing Having somebody bring the correct tools is fine, but investing in your own would definitely be in your favor.

Thanks everyone for the thoughtful feedback and support in navigating opening up my Commodore 1702 to make some adjustments. As I do not have a Microcenter anywhere nearby, I went ahead and put in an online order for some plastic/ceramic tools that might do the job. They're cheap (less than $10), will (hopefully) be coming tomorrow, and will most likely prevent myself from getting a dangerous shock or shorting out the device. A second pair of eyes on my project this coming Saturday would be greatly appreciated as I poke around back there for my first go at something like this. I've watched a good handful of videos, so I have some idea what to look for inside and I've got a 240p Test Suite on my Dreamcast that will help in calibrating the monitor.

OK. If you get that toolkit in time... great! It will be one of the safest ways to adjust your 1702. Don't let others scare you otherwise. Yes, high voltages and high current exist in CRT displays, but common sense will help you navigate the project using other tools. You don't need a specific 240p video source to adjust things. You have a 1702, and you should have whatever item/device you want to display on that 1702. Just use that item you have as the 240p source. Adjust the 1702 to that and you'll pretty much have adjusted it to everything. See you this weekend, Jeff Salzman On Thu, Nov 13, 2025 at 7:34 PM Eric Fox via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

For those who have been to VCF-East before, the 9010D room is the same where talks and conferences were generally held. When driving into campus through the main gate and heading toward the T-intersection of the road, a small set of cement stairs is located right in front of you, leading to the main entrance of 9010D. Make a right at the T-intersection and park anywhere along the road edge in that area. Just do not park on the grass.
We still need to know who plans to come to the Workshop, so please add your name to the list on the spreadsheet linked here:

As for the Hack-a-Thon that's scheduled for Saturday at the Workshop, please use the same form linked above to sign up. A separate
Hack-a-Thon
sheet was added for that purpose. Please select it from the tabs at the bottom. The Hack-a-Thon will be postponed until another Workshop event in 2026 if there aren't at least two people (or teams) that sign up for it by this Saturday. Complete details about the Hack-a-Thon are here:
