Hi! Who has a working S2I unit or is close to a working unit?

As I recall, only Wayne and Douglas have working units.

However, I think there may be others who are close.

Does anyone else have a working S2I board or something close?

Please let me know if you need any help procuring parts, making updates, or

anything else.

It would be very beneficial if we could get more units into service to

conduct some additional testing with the latest firmware from Wayne.

As I understand it, the current firmware emulates a basic 20 MB SCSI drive

with some common parameters.

It may not be fast at the moment but there are many things which can be done

to improve speed.

However I would like to find out what sort of basic compatibility the S2I

has and/or what can be done to improve compatibility as necessary.

Optimizations can wait! For instance, the Z80H CPU *starts* at 8 MHz but is

capable of up to and beyond 20 MHz operation without issue.

Please let me know if you would like be removed from the email distribution

list.

Thanks and have a nice day!
