Anyone knows since which commit, the #include "um8881f.h" code removed?

PCem v12: model.c

Code: Select all

#include "tandy_rom.h"
#include "um8669f.h"
#include "um8881f.h"
#include "vid_pcjr.h"

PCem v13: model.c

Code: Select all

#include "tandy_rom.h"
#include "um8669f.h"
#include "vid_pcjr.h"

A quick scan through the changes to that file between v12 and v13 reveals the answer as rev 740, commit 8189ea9a3ebd :

PCI changes :
- Each machine now specifies what PCI device IDs are used as generic card slots
- Implemented IRQ handling
- Added SIO chip to allow IRQ routing for Premiere/PCI

The UM8881F code was most likely removed as it was only used by the already disabled "AMI WinBIOS 486 PCI" machine, and I probably didn't think it was worth trying to reverse engineer it to implement IRQ routing as it was highly incomplete anyway.

I should add that if you're asking this because you want to bring this code _back_, you'll need to do a lot of work to bring it up to standard. At the very least PCI IRQs won't work.

Thanks sarah for the infos.

Just some input, please don't kill it, it's beautiful even if its not complete. Maybe someday when the datasheet comes out it'll complete. with the current state, even the datasheet never comes out, as long as its playable, i can live with it

Keep up the good work

I have an Epson ActionPC 2600 with the same WinBIOS and chipset if you want to experiment with it dns2kv2
