I recently picked up a HP Vectra 286/12 with 1MB of ram & 1.2MB 5.25 floppy drive. It came with a HP multi I/O board with IDE & floppy controllers and a parallel and serial port. I put in the following upgrades:

80287XL math coprocessor
2MB Lo-Tech EMS board
Cardex ET4000AX 1MB SVGA video card
Sound Blaster 16 CT4170 audio card
XTIDE BIOS for large hard drive support
Compact Flash to IDE adapter with a 2GB Compact Flash card
New 4.5v computer battery case
Teach FD-505 combo 1.44MB & 1.2MB floppy drive

I tried an Everex EV-159 16-bit memory card with 3MB of ram, but it would not work in this computer. The motherboard has a proprietary 16-bit memory slot. I have been unable to find one to go beyond the 1MB of ram except for installing the EMS board. If anyone knows where one could be obtain it would be appreciated. Here are a few pictures

Why do you want the extra ram for?

A lot of Dos programs can make use of that EMS.

There's a glitch in the matrix.

Apparently 32-bit is dead and nobody likes P4s.
Of course, as always, I'm open to correction...😉

Whats wrong with the Everex? There is no reason it shouldnt work in your PC?

Did you choose the correct config? Try testext.exe to see where its RAM is mapped and post a screenshot.

Ideally, I would like both XMS and EMS.

The board would only register an extra 512k and EMS would not work at all. I think the board was defective. I could not get it to work in my 386 computer either.
