I can see your PM, but I can't respond to it. Searching through other threads, it appears there's a minimum number of regular posts that must be made before access to submit PMs is allowed, but that number isn't listed in the thread... and I'm not going to just spam posts until I can send a PM, …

Pictures of the board when you dismantle things would be nice. There's a very small chance (not actually zero, but not far off) that it might be possible to identify the part. Maybe the problem is just a failed solder joint and a simple resoldering will fix it, at which point there's another …

I'm certain I have an extra. I have 8 of these laptops that I purchased for various parts. Someone scavenged the hinges for who knows what out of one of them, so I will verify that the board is still working properly and let you have it. I don't see a direct message link yet, so I may need to post …

Check your code page with chcp and make sure it's not getting set weird . It should be 437. If it's not, you can change it to 437 with "chcp 437" if it's prepared in config.sys. If it is a hardware issue, I probably have an extra main board I would be willing to give you if you intend on keeping …

Don't really know, but looking at a few character sets, it looks as if bit 7 bit 6 of [7..0] is stuck high. It loops 40h-7Fh twice, then C0h-FFh twice. That might mean hardware failure of some sort. [oh, further evidence, ascii 20h is space and 60h is `. So it looks like it's printing loads of ` …

Recently got this Epson Equity LT but the character set seems to be messed up: https://i.imgur.com/zXQgppw.jpg As you can see it doesn't display numbers and other special characters properly. Only letters seem to be displayed fine. I've tried the diagnostic disk to check the character set: https:// …

Lovely! Socket 7 is such a sweet spot for having 'modern' connections like USB bit still rock the old AT connections like DIN. What will you be using the system for?

Nice system 😀 430TX is such a great chipset for the socket 7 platform. I've also paired my socket 7 with a 233 MMX. What kind of 1997 games are you planning to play on this (if any)? 😀 The Curse of Monkey Island comes to mind.

Good looking case you got there! Also good job managing those cables. That's always a chore on AT systems. Well done!👍 I've never seen that plastic rail or anything like it to secure the mobo before. If the mobo fits I'd just leave it like that to keep it slightly odd.😉 Thanks! :) Yeah, that …

Nice system, though remember that AMD DX4-100 only has 8kB L1 cache vs. 16kB on the Intel DX4-100. That mobo text just sounds like an AMD advertisement to me (probably referring to the AMD P75 133MHz CPU). Also, using an ISA graphics card in a late 486 system should've been illegal! Wouldn't it be …
