The Viper 1230/28 RTC and the M-Tec T1230/28 RTC are exactly the same device. It is an accelerator which plugs into the trapdoor slot of the A1200. An optional SCSI adaptor called the MasterCard was also available for this board. Some versions of this board may have had EC030s in which case they do not have an MMU, but this has not been confirmed. This card has been reported not to work with Micronik busboards in towered A1200s. It is not PCMCIA compatible if more than 4MB is installed on the card. The 28Mhz version is a 20Mhz 030 overclocked to 28Mhz. The 42Mhz version is 40Mhz 030 overlocked to 42Mhz and the 56Mhz version is a 50Mhz 030 overlocked to 56Mhz.
