Very Rare Working 1984 Polo Microsystems Computer DOS CP/M, CPU 80188 & Z80Polo Microsystems Inc. was founded in Silicon Valley, Mountain View, Ca.
The computer was tested and is in perfect working condition. When I opened the box, the computer was stored very well and double wrapped in plastic. There was little to no dust found on the computer, monitor, and the keyboard. There are no cracks or marks anywhere. There are a few scratches on top of the computer case where the monitor stand had been previously sitting thus the reason for the scratches. The monitor works perfectly. There is no burn-in on the screen and the colors look great. The frequency of the monitor is different from the frequency of the iPhone 11 that took the photos thus the reason you see a distorted look. The monitor works perfect and is in mint condition. Both 5.25" floppy drives had their heads cleaned and tested to work. All the keys on the keyboard work as they should. The computer has a
self diagnostic test. This is really a very clean, working, and nice vintage computer.
This 'all-in-one' computer system was released by Polo Microsystems in 1984. It was marketed as a machine that contained everything you needed to run a small office - including items that other computer manufacturers would sell separately such as monitors, disk drives, a printer (no printer in this sale), and software.
It featured two microprocessors: an Intel 80188 to run DOS and PC-compatible software; and a Zilog Z80 to allow it to run CP/M software.
It also included a modem to allow it to dial-up to online services. One notable feature was the button on the upper-right of the keyboard. This placed it into a low-power 'sleep' mode from which it would wake periodically to dial-up to the user's mail service. If any unread messages were found, the Polo would return to sleep mode with a flashing LED to alert the user to their new mail.

There is no warranty and I am selling as-is with no returns.
All Sales to Hawaii, Alaska, or PR will be subject to paying exact shipping cost that will be calculated. Please ask prior to purchasing the computer.
eBay policies leave me with no choice but to mark each of my auctions with a “no return” policy. This is being done to protect me against returns such as (buyer’s remorse). After using the item for days and weeks, the buyer can submit a return and is not obligated to reimburse the seller for shipping charges and I have to pay for shipping charges back. Even though it is marked a “no return, “a buyer can still submit a return if the item was not as described or the item was damaged during shipping. Also, I do not need an eBay policy to do what is right and accept the item back if it wasn’t as described or damaged during shipping. Keep in mind, that I mainly sell vintage computers and vintage computer accessories. That said even though the box/item may not show damage, the internal mechanism may have been damaged or jarred from a rough truck and/or plane ride. I will work with ALL my customers to resolve the problem. Recently, I have had to take back items where the buyer didn’t check with mom/dad, husband/wife, or God prior to buying and did a return. eBay forced me to take the item back. Personally, I do not think that this is an acceptable way to return items. Many of the sellers on here are just trying to provide for their families and this kind of previous return is not fair to the seller. We are not Walmart or Costco that cannot absorb these financial damages. Again, I will work with all my costumers to ensure that they are happy with the item they purchased. Thank you for your patronage.
