The devices are designed for use with the Motorola 68450 series DMA controllers (see my other auction). I can email a data sheet for the base MC 68010 device (in .PDF form) or or it can be downloaded here :-

The devices have been stored in an anti-static environment, both when they were in the original card and as separate components. The anti static environment will be maintained during shipping.
If you require more than 2 devices, I have a small supply available.
Thank you for looking.
