1IBM EGA COMPATIBLE.*UNISYS ENHANCED GRAPHICS CONTROLLER  VERSION 1.30  
2  (C)Copyright Sigma Designs, Inc 1985,1986

Status: Working at 4.77Mhz

Jumpers/Switches are the same as on a genuine IBM EGA card:
SW1-4: configuration switches
P1: configure pin 2 of video connector to be GND (for CGA monitors) or RS (for EGA monitors)
P2: light pen connector
P3: configure EGA for I/O port 3x0 or 2x0 [but BIOS doesn't have support for cards at 2x0]

Notes:
Card does not work in a Turbo XT system at 10Mhz (but it's fine at 4.77Mhz). Apparently neither the ROM nor the RAM chips (120ns) are fast enough.
Haven't bothered to test the serial port.
ROM is 16KB, labelled "UN 1.30".
The L1A2334 chip is a custom Sigma Designs gate array that implements the 'glue logic' and the hardware portion of the Sigma CGA emulation.

2  (C)Copyright Sigma Designs, Inc 1985,1986

Status: Bad RAM chip (U6) on M3D0-M3D3 (low 4 bits of plane #3), freezes system during POST
Status: appears to be working, requires multisync TTL display @ 31.25khz (or possibly even higher)

Jumpers/Switches are similar as on a genuine IBM EGA card:
SW1-4: configuration switches (somewhat similar to the IBM EGA switches I think?)
SW5: enable CGA hardware emulation? (When ON, shorts the light pen switch input to GND.)
P1: configure pin 2 of video connector to be GND (for CGA monitors) or RS (for EGA monitors)
P2: light pen connector
P3: configure EGA for I/O port 3x0 or 2x0 [but BIOS doesn't have support for cards at 2x0]

Oscillators:
28.500Mhz (CLKSEL=00)
32.000Mhz (CLKSEL=01)
'SPARE OSC' (CLKSEL=10)
EGA feature connector (CLKSEL=11)
Video BIOS uses CRTC register F9 to program an extra divide-by-2 stage so that the card is able to generate standard 15.7khz / 21.8khz modes from the high-speed oscillators.

Notes:
Card fails to POST, error beep is long-short-short-short, and then the system freezes/fails to boot.
ROM is 32KB, no label on the chip. Card only decodes C000-C3FF (16KB).
Hidden underneath the ROM socket (!!) is a PAL16L8 device that responds to I/O writes at port 03CBh and switches between the upper and lower 16KB banks.
The L1A2334 chip is a custom Sigma Designs gate array that implements the 'glue logic' and the hardware portion of the Sigma CGA emulation. This chip has some kind of emulation control register at 03DCh.
SW1 is stuck in 'OFF' position so I rigged up a jumper wire for it.

Manufacturer/Identifier: NEL ELECTRONICS / "ULTIMATE EGA+++"
Chipset: "UDL" C3 (8737KK)
BIOS-String: NEL INTERNATIONAL 1987 IBM EGA COMPATIBLE SMART BIOS 5.93 11/17/87
Status: working in XT systems at 4.77Mhz and 8Mhz, display corruption at 10Mhz
Oscillators: 16.257Mhz and 27.648Mhz

Card had 120ns memory installed. I tried 100ns memory, but the card is still unstable when running the bus at 10Mhz. Writes to display RAM are fine, but reads often fail to return valid data = corruption when scrolling etc. I suspect it's actually the ASIC that can't keep up with the 10Mhz bus.

No datasheet or other documentation appears to exist for the "UDL" series of chips. There are sure to be some "Super EGA" modes available (given the 27.648Mhz oscillator on the board) but no idea how to access them or what kind of display they might require.

Hi there,

Sorry to bomb this thread, but in the interests of digital preservation, I thought I'd add an EGA card I was working on last night to the list incase anyone is looking for ROMs.

Manufacturer/Identifier: Juko ST (NEL Electronics)
Chipset: UDL C3
BIOS-String: NEL INTERNATIONAL 1989 IBM EGA COMPATIBLE BIOS 6.04 09-09-90
Status: Unknown - haven't got it tested yet...
Jumpers/Switches: again, not tested, but I think it's similar to the NEL/Juko Ultimate EGA: https://arvutimuuseum.ee/th99/v/I-L/50064.htm

Interesting how the ROM is labeled Juko ST, which appers to be a motherboard BIOS (Juko XT Super Turbo I think) but the contents of the ROM does appear to be a Video Bios extension. Also a later version than on this thread and here EGA Card Restoration Attempt.
