Refurbished IMSAI 8080 48KB Computer withMany Boards

Refurbished IMSAI 8080 48KB Computer w/Many Boards. This is a very good condition IMSAI 8080 computer.

IT appears to be in working condition. It appears to have 48KB of SRAM installed on 4 boards. The computer tries to boot drive A of an attached dual 8 floppy drive Thinker Toys when the RUN switch is activated. I do not have the proper board to test with a terminal. The system appears to have been used in a University setting for a Speech Research Lab.

There is a speech card in this unit and there is a lot of speech related documentation included. The computer was disassembled and blown/wipe dust free thoroughly.

The PSU cleaned and dusted. The main BUS board dusted and air dusted.

The PSU was slowly powered up over 4 days to let the large capacitors revitalize. The PSU is showing voltages a bit lower then a "new" PSU would show for both rails. The 18 volt rail is about 17 volts no load..

And the 8 volt is showing about 7.1 volts no load but the computer does boot with all cards loaded. The front panel LED's all appear to light up. All switch leavers were cleaned. The 2 blue leavers were broken. I was able to replace them with 1 blue and 1 red (see the left front panel).

The 2 broken leavers are in a baggy inside the case. All socketed ICs, and there are a lot of them in this system, have been reseated.

All card were blown dust free and the card edges, from top to bottom, were cleaned. The ribbon cables were cleaned. The power and I/O ports were cleaned. The fan and the fan housing have been cleaned.

This computer comes with its original IMSAI owner's manual/binder. It too have been cleaned. There are many additional manuals and documents included for this computer. Many are manuals for the included cards. The cable's pin-out do not match this computer.

The Reset and Run leavers are just a bit loose but work correctly. Boards that are included front to back. TDL The ZPU Rev 1 1977 Z80 CPU Board. IMS Assoc Ic RAM-4A Rev 2 16 RAM Chips.
