February 21, 2010 at 12:07 Rare Microsystems MS-21C-E laptop
By chance and Russian post, a wonderful piece of metal fell into the hands - a rare Microsystems MS-21C-E laptop.
This miracle of technology looks like this: The condition at the time of getting to me was pretty dead, but after preventive disassembly, the machine works as expected. Approximate configuration: CPU i8086 8Mhz, RAM 640Kb, there is also a bootable ROM disk with DOS 3.10. The matrix size is quite decent 10 "with an aspect ratio of 16/9. It also has the unique ability to use AA batteries by modern standards. It was released in Japan around 83- 86 years old, the exact date could not be established.The only mention on the network was found here
The design is pretty common at the time: a gray rectangular box :)
Interestingly, the power connector is on the front, I have never seen such a solution in laptops, although at that time it was probably the standard solution.
Also in front is (was) a hardware power switch, a card slot, and a reset button (a small semicircular hole on the right). On the left is nothing remarkable, except for the power compartment. On the right is a hard monitor contrast control and two memory card slots or expansion slots of an unknown format. On the rear panel is a strong set of ports, which I can envy also many modern laptops:
From left to right: modem connectors, printer port, unknown expansion connector (I assume for a docking station or external hard drive), ground screw (!), Monitor MDA connector, COM port and external drive. For comparison, next - Asus EEE PC 701 We find in the bins a suitable PSU and run. The bios battery naturally died for so much time, and the usual BIOS settings menu was not found in it. Accordingly, the settings are changed by dip switches on the bottom of the case. We admire the proud Japanese DOS 3.10 and the contents of the C drive. Having admired, like any decent piece of iron, I decided to make out and see what was so interesting inside (well, to show everyone at the same time).
Decided to start with a small battery box.
It found 6 slots for batteries, a stabilizer and a huge connector for fifty contacts. An unknown slot with contacts was also found, most likely there was a backup battery necessary for working during the battery change in the main module. We pick up a screwdriver, open it and ... Everything is easily and simply disassembled without any latches. A yellow battery - bios backup power. Shawls grow in 2 floors on pin connectors. Here we see a brutal modem :) the speed is clearly about 2400. ROM disk and RAM. Power Supply.
A heavy-duty card reader with an electromechanical drive, cards for it should be similar in format to standard bank cards. Well, actually the motherboard. Speakers such as PC Speaker :) Disassemble the monitor ... Remove the matrix. We looked and you can collect and test whether all living things after disassembly. The hardware contrast regulator is an interesting thing :) After studying the vastness of the network, I found a way to finish the usual 3.5 "floppik for screwing to this unit, which I plan to do in the future.
