# LT6502b complete!

> A hobbyist write-up of the finished LT6502b, a homebrew 6502-based laptop: half the thickness of the first version, a 10.1-inch 1024×600 screen, translucent orange case, and a wishlist for the next revision.

Well, I had a chance to get my head sorted and I finally finished the “b” version of the LT6502

Here you can see it next to the first version, I changed my mind about the case and went for translucent orange, it’s way more vivid in real life. I really do like the translucent material, it’s really different 🙂

The first big thing that’s different, it’s half the thickness of the old one;

It also has a larger, higher resolution screen. The screen is 1024×600 and is 10.1″, the previous one was 800×480 and 9″.  
It has a similar battery capacity, so should last about the same amount of time.  
It’s a little faster, 10MHz instead of 8MHz.  
It has a SID emulator on board and a WiFi Modem.  
It doesn’t have an expansion slot though. The aim was to make it more “sleek”.

The screen also has a better contrast ratio being IPS rather than regular LCD, and the higher resolution really does show.

Here is a good example of that, and also the extra rows of text you can fit on the screen!

There are, of course, somethings I’d change

- The holes and support for the heat inserts need making bigger and stronger, they’re VERY weak.
- CAPSLOCK led under the capslock key
- Find a better WiFi Modem, this is too slow and a bit flakey for real use.
- better speaker, it works, but it’s a bit “anemic”
- Faster, start with speed in mind (i.e. figure out how to copy ROM to RAM and switch out ROM)
- Better battery solution, I’m thinking something 18650 and on the back as part of the “hinge”
- USB PD support that doesn’t need preprogramming of the USB-PD chip to limit it at 5V, would be nice to have a buck/boost convertor to take anything USB-PD can throw at it and make it 5V
- Better sound chip, the SID is ok, but it’s a bit limited by modern standards.
- I really want to be able to read a FAT16 file system on the CFCard rather than my own custom one.
