More stuff for the collectors

I found an old Quadram quadboard in my junk collection.  This is a 256K
(41256 DRAM) add in board for the 5150.  Also includes a serial port
(8250), a parallel port (8255) and a clock (some small 19-pin OKI chip).
The board bears a copyright of 1982 and the chips have date codes in early
1983, so this is a very early critter.  

To my recollection, this was usable only on the 4.77MHz motherboards, but I
could be mistaken.  The original "wide" PC mounting bracket has been
replaced with a conventional narrow one, so this board has probably seen
duty in a clone.

I can populate the board with DRAMs if necessary.  I think I may even have
a software diskette and manual for it, but I'm not completely certain.

Let me know if you're interested.

Cheers,
Chuck
