Looking for ALS Z-Card (CP/M clone) Rev 1 documentation

[datajerk <datajerk@gmail.com>]

I just acquired an ALS Z-Card Rev. 1 for my newly acquired IIe.  I
placed the card in slot 4 and it works just fine.  But I am unable to
determine the speed of the card.  The CPU model number indicates its a
6MHz chip (Google search), however a benchmark indicate otherwise.
Unfortunately I do not have another 6MHz to compare it with.  All I
have is Virtual ][ on my Mac and I am starting to ask myself how
accurate is emulated performance of memory intensive code?

There are 4 dip switches on the card as well.

The quickest way to solve this mystery would be to find the docs.

Thanks.
