What is this?

Note that the base model includes the bare PCB only, select the optional components you'd like included when purchasing the product.

The roscram01 is a configurable memory expansion for the rosco_m68k retro computer (sold separately), capable of expanding your memory with 1, 2, 3 or 4 whole megabytes of fresh RAM!

Someone once famously said that no-one would ever need more than 640KB of memory, and we all know how that turned out. Your rosco_m68k comes with a whole megabyte of on-board RAM, but if you want to do more with your computer, such as running more demanding programs or processing larger data sets, then you'll probably find that a RAM upgrade is just what the doctor ordered.

Features

• Install 1, 2, 3 or 4 megabytes of expansion RAM into your rosco_m68k
• Uses the same static RAM chips as the main computer does
• Connects directly to your rosco_m68k's expansion connector
• Configurable base-address so you can have your RAM wherever you want

Who can build this?

Just like the rosco_m68k itself, this is designed to be easy to solder, and no special skills or equipment are needed! Simply grab a regular (ideally temperature-controlled) soldering iron, some solder (we like lead-free 1mm diameter) and have at it!

• All-through-hole design, only basic soldering skills required
• Plenty of space around components, no fiddly bits
• High-quality solder mask and tented vias reduce the risk of hard-to-spot bridges
• Fully-socketed option at checkout to eliminate the risk of heat-damage to the ICs

Where supplied, all components are brand new and of the very highest-quality we can get our hands on.

What else do I need?

You will need a rosco_m68k - if you don't yet have one, you can get one right here from our Tindie store!

You don't need any special software or additional hardware to use your new RAM expansion - your rosco_m68k is all set to support this as soon as you've soldered it up.
