  I have a 50% artworked KLM-367 replacement layout in my PCB CAD, but I 
stopped to consider a dilemma: make the board a direct clone of the 
original KLM-367 and use the 8048/8748 CPU and 5514 RAM, or use something 
like a PIC16F877 and rewrite the patch manager OS in PICcode.  I do not 
know how much longer 8748s (EPROM version of the 8048, needed to replace a 
dead 8048-345 mask-ROM CPU from a KLM-367) will be available; already I 
have to resort to NOS or chip-pulls to get a stock of 8748s or 8749s.
