Notes Tbe Commodore 128 was intended to follow on the Commodore 64's success and compete with the likes of the Apple Macintosh and IBM PC. It was twice as fast, had twice the RAM and added a Z80 processor for CP/M compatibility. These were not enough and the machine failed to carve out a significant market share. Ultimately the Commodore Amiga turned into a far bigger success.

A very interesting Commodore article about the machine dubbed "The Most Versatile 8-Bit Computer Ever Made" appears on the Canadian Commodore site.

The Commodore 128 Computer box

The Commodore 128 in my collection comes in its orginal box which is in very good condition for its age.

Contents of the Commodore 128 box

Inside can be found the system, power supply and a variety of connecting cables.

The system is clean but I haven't yet had a chance to hook it up to see how well it might work.

I have a C128D. 128 mode does not work, ergo, i do not use it. But, 64 mode is GREAT!!!!!!!! I play M.U.L.E. all the time. The tape player I have always crashes. Still, I have heard it is worth (all together) over $650 USD. I may (i said MAY) sell it on Ebay.

Bought my C128 18 years ago because I loved playing on the C64 but never owned one. Somehow convinced my parents to buy me the C128 which in the UK cost so much more. Especially the game Elite. Lets face it this was the best thing ever. Bed time came far to early, I still have the original game boxed with some sort of story manual. Should I keep this all for when my kids are of age? Do these old games still turn me on? Not sure. I used to let the old tapes load whilst I went to play football only to find they had crashed on my return. The 5.5 disk drive was a novelty item but still a great accessory to have.

I use a C128 daily, keyboard problems arise, keys become hard to strike. The c128 keyboard fix is easy, small pieces of .200 long plastic tubing (.120 - .125 diameter polyethelene) must be inserted into the key hole. This tubing can be obtained from an upholstery supply. It is called 1/8 welting or piping. Cut small pieces exactly .200 with a rzor blade. Keys can be popped off with a small screw driver (be careful).

I bought a C128 on Okinawa in 1986 and used it for a number of years. I still have it in the original boxes, except for the monitor. It still worked before retiring it long ago. I wonder if it still does? As an aside, I was in the Navy in '86 and the 2 nurses in our department used C64's for patient databases?

When I was 7, I was the proud owner of a Commodore 24, yes a 24. My mom built it for me. Please tell me, was I the only one to have it. Are there any urban legends surrounding it. Can anyone help me.

I was a senior in highschool working in the electronics department of K-Mart when the C-128 came out. Instead of working, I spent hours writing programs to feak-out customers with crazy sounds and light shows whenever they touched the keypad. Good times.....

I remember seeing it when it first came out in 1985! I drooled over them at the Dept. Stores. I had a C=64 at the time. I now own like 3 of them along with C-64's and a C-128D too.
