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.
