The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

The Real Time Clock is somewhat similar to the [[Real Time Clock|CPCI Real Time Clock]] released in a special issue of the same magazine, but not identical (the RTC chip has different pin-outs, and some of it's 4bit registers are working slightly different, the leap-year bits, for example).
Databoxes: '''UHR8000''' RTC-RAM-driver in 10-1986 (hex listing, plus [[Hisoft Devpac]] source code) (caution this version uses incorrect I/O addresses FBE1-FBE3), '''UHRC000X''' RTC-ROM-driver in 4-1987 (this version uses correct I/O addresses FBE2-FBE4).

'''Note''' - The Schneiderware Real Time Clock is somewhat similar to the [[Real Time Clock|CPCI Real Time Clock]] released in a special issue of the same magazine, but not identical (the RTC chip has different pin-outs, and some of it's 4bit registers are working slightly different, the leap-year bits, for example).
The I/O ports are also slightly different: The Schneiderware version has additional control bits in port FBE2h, and, for whatever reason, it splits data to two separate addresses (for FBE3h for writing, and FBE4h for reading), rather than mapping both to FBE3h.

'''Caution''' - The listing in the magazine (and the databox files) are bugged and won't work: The I/O addresses are wrong. Additionally, some function entrypoints seem to be accidently set to 0000h.
