Another no-fault upgrade for original 5- or 8- slot PCs, is the hybrid
Bullet motherboard, 8,10,12, or 16 Hz 80286 processor, 8-bit bus run
at 4.77 MHz so you can use your old cards. Cost is about $130-190
(depending upon speed) plus 1 meg of DRAM 256K (150, 120, 100 ns,
depending upon processor speed). Memory above 640 K is a dedicated
ROM hardware disk cache. We did this to a 5-slot PC at work with
the 10 Hz board for about $240 complete. This board is made to work
with PC-only keyboards and to fit PC & XT chassis's easily. For sec-
retarial work, we have not found the lack of 16-bit buss that limiting.
We got ours at D.P. computing (see the Shopper, also Leo Computers).
