Mosaic RAM Master 32

Post by mrr19121970 »

I just received one. I have no idea what it is, but assume a 32kb ram expansion. At the side there are switches 123R5W and jumpers XP

Any idea what it is? and what these switches do? Google revealed nothing for me

Update


More googling lead me here

Mosaic Electronics has introduced the RAMmaster 32 for the VIC-20 computer. RAMmaster 32 includes a built-in expansion port, a pause switch, a write protect switch, and a relocatable memory block.

The unit, which adds 32K of memory, also has a disabler switch so cartridges can be removed without turning off the computer. RAMmaster 32 is expected to sell for under $150.

No I didn't actually. Just like you I found nothing on the switches, but I figured most of them out.
I have no idea what the jumper block does either.
All I know about how it works was in that thread you found.
