Hiya!
we have made a new thing and since this 2nd prototype is very close to the final version it is time to officially unveil it 😀


This is a 4in1 design aimed at 386 and 486 ISA systems or bridgeboard environments (like the amiga) where slots are a premium
The main features are:
- Cirrus 5434 VGA controller with 2MB vram
- Opti 82C930A sound controller with a Yamaha OPL3 (SB/SBPRO/WSS)
- PCMIDI mpu-401 interface
- Realtek 8019 network controller with bootrom support
The VGA portion jumpers are the usual one can expect from a later isa vga card: disable jumper , 0WS , IRQ2 and lastly 2 selectable video bios banks.
We have also added the FEATURE connector for use with the CRT Terminator card.
The Joystick port is on a header (top left corner) and a standard joyport bracket can be used. (there was no free space on the backside of the card and the bracket needs to be designed - once the card is really finalized).
For the PCMIDI MPU portion we have the usual midi routing jumper block so one can create combos with ports and pcmidi or opti mpu.
The nic bootrom can be used for stuff like XT-IDE bios , Y2K fixes etc
All eeproms used are of the 29F010/020/040 PLCC32 variety.
This is again a 4-layer board design , filled to the brim and as small as possible.
Please keep in mind that this is a prototype and thus it does not use all "higher tier" components for resistors/capacitors like the final version will.
More info will be posted on the card's site: https://pcmidi.eu/sonicvisionpro.html
Here are some more closeups of the various sections:






Comments and thoughts are welcome - but do keep in mind any additions or alterations can be impossible to be made at this stage...
