Techworks IIsi network / FPU card help

[Byte Knight]

Hey guys,

I recently picked up a Techworks IIsi Ethernet network card set for my yet-to-be-running IIsi. And I paid a lot more for it than the IIsi itself!



A couple of questions:

• Does anyone have a manual for this? It's got a couple of jumpers that I'm not sure are for what. I do have an install disk.
• Would a 40MHz 68882 FPU work with this or do I need a 20MHz version which the oscillator is set at?

Thanks!

Sorry you never got a response to this. I think Techworks became MicroMac if I'm remembering correctly.
It may also be a Cache card

It's all good. I found the manual here: https://www.retrotechnology.com/z/techworks.pdf

I don't see any mention of a cache connector in the manual. Is there a way to tell if the upper connector is PDS vs cache?
