Commodore CBM-II

Year Released1982

System Overview

The Commodore CBM-II is the follow-up system from the Commodore PET. Launched in 1982 after the PET discontinued, the CBM-II shipped in two different versions. Both the P & B series (Personal & Business) that were produced for the two different markets. There are 6 models in total made of the CBM-II. Each had their own RAM configurations or with an additional co-processor card in the high end 630 & 730 models.

Both versions utilised the MOS 6509 processor, the personal version clocked @ 1mhz and the business @ 2mhz. Two main RAM configuration options for both series came in either 128k or 256k versions. 64K and 192k versions of the CBM-II originally planned were dropped early in development.

The P series cancelled in the US before it became available, primarily due to the popularity of the Commodore 64 which launched also in 1982.

The CBM-II was a short-lived product, due to high manufacturing costs and being tricky to develop for. The fact the C64 released meant the P series would unlikely be adopted in high numbers.

Emulating the Commodore CBM-II using a Raspberry Pi

The Raspberry Pi is a compact single board computer which has become very popular for emulating retro computers and consoles. You can buy the Pi very cheaply and has a whole community supporting and building accessories and applications that are compatible with.Significantly, for Retro Gaming enthusiasts, the Raspberry Pi offers fantastic all round emulation of many systems. It offers the ability to output games on HDTVs via HDMI or older CRT TVs via composite outputs. Combining the Raspberry Pi with Retropie, you have a device capable of emulating anything from the Atari 2600 to the Sony PlayStation.Check out the different Raspberry Pi packages you can pick up on Amazon using the button below.Check Raspberry Pi prices on Amazon
