980004 - 8228 MAU and ICS cable. TokenRing, one of
"The Seven Wonders" of PS/55 junk market.
Ok, there were so many used PS/55s with TokenRing Adapter installed but NO
ICS cables nor 8228 MAU were found in Akihabara. I could not imagine how the
ICS cables and 8228 looked like. As a M.A.D, I had dreamed about 8228 and ICS
cables to build my own LAN. But so far I could not get any Token devices except
adapters. May be ICS cables had been cut off at adapter sides and only PS/55
system units were collected and sent to junk market when some big companies
replaced their systems. No idea about 8228. There were so many TokenRing
adapters so there might be 1/8 of 8228s at least. But, I had never seen one in
any PC surplus shops or street junk shops. The fact that NO 8228 nor ICS cables
but plenty of TokenRing Adapters in Akihabara was/is one of the seven wonders
of PS/55 (at least for me).
A friend of mine in Nagano prefecture got some patch cables for Ring-in
/Ring-out connection. He asked me to buy some D-sub 9 pin connectors for him in
return of 2 patch cables. What a nice proposal! I bought some connectors for
him and sent it. I received 2 patch cables from him. One was about 10m long and
the other was very l-o-n-g. I made 2x 5m length ICS cables. Kept long one for
future usage. Thus I got 2 cables for TokenRing connection.
One day I got a mail from my master of MCA. He said he had gotten 8228s and
he could part one to me for free except shipping. Who could refuse such an
offer. Yoda sent me a 8228, a lightning sword of TokenRinger, to me. Though the
sword had some rusty spots here and there, it was completely functional.
Thus I could get mysterious items. I was reedy to be a TokenRinger.
First stage of my TokenRing network:
5580 / OS2 Warp Connect, 5560 / Win95, 5551/Win95. 5580 acted as File server.
NetBEUI was used as LAN protocol. TCP/IP was difficult for me.
Now, 8228 with rusty spots still sits on a shelf with 5 ICS cables and 3
ICS/RJ45 filters. I now also have a small MAU made of Sumitomo with 4x RJ45
ports which will be used when I may leave my home again in future. 8230 type-2
CAU/RJ45 LAM may sit here for a while waiting for it's new home. No enough
space to keep them. Also got some ICS cable NIB for JY100 (about $1.00) per
cable (some of them were parted to my friends.) Mr. S reported he found many of
Sumitomo made 8228s sold very cheap in Yokohama in 2001. I myself saw IBM
genuine 8228s sold NIB but they had unnecessary "0" printed on their price
Now this moment, what I really want to have is "8229-002 (Token/Ether
Bridge)" or any types of 8229 if it's has Token/Ether bridging unit in it's
slot. Occasionally it comes up on eBay but most of 8229 seen there are 8229-001
or 003. Sigh...
