Hi all,

We all have ALPS printer modules with broken pinions.
Who knows a replacement part ?

As told by Paul in the forum :

“The pinions measure 3.75mm OD and have 13 teeth. The shaft measures 1.55mm. I’m thinking that this is very similar to some remote control helicopter pinions I found online – 13T 1.5mm shaft mod .25 (101P). I’m going to check with a local RC hobby shop to see if they have anything, but otherwise I’ll try to order some of these pinions (http://www.xtreme-production.com/xtreme … ts_id=3013).”

Someone used pinions from a Sony CD player.

Frank C. ODDS presents his favorite printer for the Sharp PC-1500 : the MCP-40.

The MCP-40 printer — identical, it seems, to another model called “Oric 1” — was a four-colour printer plotter that used a rotating “bullet chamber” device identical to the one in the Sharp CE-150. But the MCP-40 printed on paper rolls 114 mm wide, thus offering larger results than the “bus ticket” output of the CE-150.

The MCP-40 connected to computers via a 36-pin parallel port connector that reduced to a 25-pin DIN connection at the computer. It connected directly to the electricity mains. It therefore functioned more like a full-sized printer than a pocket computer add-on. The printer connected to the PC-1500 via the parallel port on the CE-158 serial/parallel interface.

For printing full-sized text output from the PC-1500, a serial or parallel port connection to the dot matrix, tractor feed type of printer that was widely used in the 1980s. But the MCP-40 came into its own for graphic printing: the four-colour capability, together with the ability to draw smooth lines in any direction, meant it was ideal for plotting graphs and drawing computer-generated diagrams. The MCP-40 sold for a relatively cheap price, making it a great value add-on for a Sharp PC-1500 set-up.
