yes, i can do that. Do you have wiring diagrams or would you like to design the whole project by me?

I need from you: - schematics (on paper or in PDF) - list of components; values are not important but I need know cases (thd, smd) - requested pcb size and form - location of holes, switches, etc. you get - re-drawed schematics - components topology on pcb - Gerber files - Excellon files on request ...

If you only need a copy of the EPROM, this option does not matter. Read the contents of your EPROM and program a new EPROM with the file and the same option.

Offer bespoke printed circuit design, THD and SMD for digital and analog systems. Possible PCB production.

The connection between 80C188/80186 and 8087 is possible via a special interface circuit 82188. I've never seen the 82188. I only know him from a small photo. Many years ago I had a message that this chip actually existed, but was only available to military customers. There is an application note (A...

that's easy. I cannot describe here in detail how a new component is made step by step. Please note that each component has - schematic symbol - Package symbol The schematic symbol is just a visual image for drawing a schematic. In the schematic symbol, the correct number of connections (pins) is im...

I suggest you to use Jupiter GPS receiver which has 10kHz signal rather than 1pps. The 10kHz signal can be used for PLL to tune 10MHz local oscillator.
