Re: Help with mapping out a Single Board Computer (SBC) - 486-DX2-80 - Innovative Technologies, Houston, Texas

IDE Socket - 44pin and also 40pin - F82C735 While there were only few likely contenders, I decided to search for which IC controls the IDE ports - particularly as i wasn't sure what that other 40 pin was for. The CHIPS F82C735 controller handles not only the IDE port but printer port, com ports, …

PS/2 Keyboard Pin out - CHIPS F84041 After getting VGA out, was keen to access the BIOS and see what options were available. Given that this era computing typically had PS/2 keyboard and mouse sockets on the board, i went looking the Chips IC mostly likely to control the keyboard and mouse. Then …

Video Output Test Good to see it boots and the ram on passed the initial test (32MB will plenty for this), the CMOS battery was clearly dead, but a little disappointed that it was only registering 66Mhz (but hopeful i can benchmark this properly at some point). For power, I threw together pico psu …

VGA pin out - CHIPS F65548 - FlatPanel VGA Controller From reading through various SBC docs, many of these era industrial SBC were designed to be able to be used with either digital LCD panels or VGA monitors. Scanning the PCB, i noticed a large IC that I suspected might be part of the video …

Help with mapping out a Single Board Computer (SBC) - 486-DX2-80 - Innovative Technologies, Houston, Texas

A few months ago I acquired the following neatly sized 486dx2-80 and SBC motherboard off a local market place advert but unfortunately couldn't find much user information at all on it online. I have slowly been going through studying the ICs - ie reading through 'Chips' datasheets for pin outs and …

Re: Newly made PCMCIA sound card

Looking forward to buying a few! Another alternative could be to use a right angled IDC pcb socket and a standard ribbon cable (maybe a 16pin or larger one if more pins if needed and it would fit). Thats if its just case of using the pcmcia adapter to connect to another daughter board. Cant wait to …
