990729 - 6860 PC720
As you know there is a strange L2 cache socket on Reply PowerBoards. It was
told that the memory access was slow on Powerboard and L2 cache would solve it
and boost system performance. I don't know logic but I do love to populate if
there is any empty socket, slots and so on. Thus I wanted L2 cache which could
be used for M70/M80 PowerBoard.
One of the forum member reported that he could use a
"L2 SuperCache", a genuine part for
PC720, on his M70. PC720, a nice little
machine with PCI/MCA slot and additional PCMCIA /A. I really did not wanted to
buy or get MCA systems any more. I had to left space for future coming
Trolled around Akihabara as usual. At a PC surplus shop I found a 6860-J4G.
Price tag said JY2,000. A store clerk kindly opened it thus I could confirm L2
cache was there. Didn't want the body but really wanted the cache module. I
paid money for the system.
Back home, I tested the system for a while. For detail please see
PC720 page. Lovely machine it was. Low
profile, space saving, PODP ready, S3 SVGA and EIDE... If I could find an
appropriate CD-ROM drive it would be a nice machine for BBS connection instead
of the 5560, "Big Battle".
I pulled out the L2 cache module and set it in M80 PowerBoard to see if it
would work or not. As the reporter told, SuperCache worked fine on my M80
To keep the module in the PowerBoard or to use PC720 with the module, That
was the problem.
Few days latter PC720 took the place on my desk. Loaded a 2G HD drive (700KB
for system, 800KB for data and the rest of 500KB was left unpartitioned because
there were bunch of bad sectors/clusters on the drive), installed Win95B and
PC Card Director for PCMCIA /A, popped a 28.8Kbps modem card into PCMCIA slot,
populated 4x SIMM slots with 16MB SIMMs, PC720 became a nice tool for accessing
