and an implementation of that on a 286 project board here
Hi,
I am trying to squeeze as much higher addressable memory as possible, and with some bioses only taking 8k in a 64k block , I wanted finer granularity in that block.
I am using a lotech design reference to help teach me on how to do this.
So for example I want to enable E000h to EE00h which...
Hi all,
Heavily inspired by the lo-tech.co.uk TANDY 1400 card, I made another TANDY 1400 card, tested on my 1400LT.
It adds HD storage through the XT-CF-Lite , and integrated Realtek 8019AS ne2000 LAN. I really wanted to add audio but with the 200mA limit I stopped with the LAN and XTIDE.

A 110v would do too but it would have to be the International version. It would say international on it.
Can offer delivery address in...
My Plus before the analog board died.
Hi, I am trying to get my Plus back up and running. Its a 240V/International Analog version. I have recapped it and checked the diodes, and optoisolator, but I still get the flup flup flup no power on.
Apart from the Dead Mac Scrolls, is there any other...

XTIDE etc. It will be interesting to see what you can get working in the thing.
