Free single boards -Z180

Hi All,
After I upgraded some network I end-up in my stock with some boards.
I have more then 150 of them. I have to clean up my back office and I feel
guilty to
throw it away. But I have no choice. It is very neat board. I designed few
projects,
which working fine for me. It is not top of line board, but for someone it
may be good.
I have schematic diagram for it, which will explain you every I/O and memory
maps.
It is not E-Bay item. To use it you have to have knowledge of what are
doing.
Board:
CPU: Z180 � crystal 12 MHz
RAM: 128 MB
ROM: 32MB +
Battery backup, RTC (DS1202S), DID chip, RS485, full VFD/LCD (HD44780 or
equivalent)
Interface, TTL serial port, keypad 4x5 output connectors. Beeper.
Power: +5 V less than 0.7 amp
Size: 5�x 5.5� or 125 mm x 140 mm
Need a picture I will send it to you.

If you are willing to pay for parcel (the cheapest way by CanadaPost by
ground) + $5.00 CAD for envelope, you will get it.

Thanks
Al

How did you get it to address more than 1MB?

By paging, and copying the int vectors into the top 64m maybe... and the
'switch ' area code has to be duplicated as well... Did it on a Z80
once...mapped an 8K eprom into a 2K space.

I was pretty sure you meant 32K ROM and 128K RAM.  I was half right
anyway.

How much to ship say 3 boards, with docs, to the USA (Maine).  Not
sure if I would ever actually use it, but I would like to have such
a beast handy.
