Hi all ,
my first post here. I am looking for information about a little SBC / industrial PC board i got hands on about 30 years ago and dug out recently.
I would likt to build a DOS PC using this board. I found a post from Maeslin about a CPU upgrade on a similar board. Maybe Maeslin can help since he mentioned
manual and full documentation for his board ... I am to new here to pm him.

Odd little project: Socket1 P24T conversion

I had no luck installing DOS 5.0 / DOS 6.22 . Using a FlashFloppy DOS6.22 always hangs up at display "Starting MS-DOS".
Using the same method i could boot into DOS 5.0 but the install stops/hangs at about 11% ...
The CPU is a DX66 but reported as DX50 by BIOS. Maybe some jumpers are not set up correct.

The board has a socket for Disk on Chip 2000 and i have a 16MB module, woult it be possible to install DOS to that Module ?

CPU is now at 66 and DOS5.0 install running ( was just asking for Disk2) ...
