SAM Coupé ROM Images

Granted

From Simon Owen:

This archive contains many versions of the SAM Coupé 32K ROM image, released
with kind permission from the ROM author, Dr Andy Wright.

Thanks to Simon N Goodwin for supplying the files, which include two dumped
from pre-production hardware (and which only work with the early hardware!).

Beware - the early ROMs are very buggy, and tend to go mad once BASIC starts
paging. ROM 10 (version 1.0) requires the CALL after F9 or BOOT because the
ROM loads the bootstrap but fails to execute it. The address depends on the
RAM size:

On a 256K SAM:

CALL 229385

Or on a 512K (or larger) machine:

CALL 491529

MultiROM

Peripheral

Rooksoft


From Sam Users Mailing List November 1994:

MultiROM Technical Data v 1.0
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

Copyright (c) 1994 Rooksoft and Entropy.

The MultiROM is a trademark of Rooksoft.

HARDWARE:

This data sheet is a pre-release document for the new MultiROM with hardware from ROOKSOFT and software from ENTROPY. This document is intended to provide programmers with sufficient information to enable them to write software that will operate within the MultiROM.

The MultiROM is an add-on unit which plugs into the SAM Coupe expansion socket and can override the SAM’s internal ROM. It will provide an environment external from the normal SAM operating area from which programmers toolkits can function, such as assemblers, debuggers, disc repair/recovery toolkits etc.

The MultiROM will have either a 128K, 256K or 512K byte ROM (depending upon the amount of software to be included), and a user choice of either 32K or 128K battery backed static RAM. Both the RAM and ROM are sectioned into 16K pages which are selected by writing to either port DE or DF hex. Port DE controls which RAM/ROM page is paged in inplace of ROM0, while DF does the same for ROM1. Each port is identical except that they each control ROM0 or ROM1; the bits are as follows:

bit 0 Page select bit 0
bit 1 ” ” bit 1
bit 2 ” ” bit 2
bit 3 ” ” bit 3
Bit 4 ” ” bit 4
bit 5 ” ” bit 5 (only used if ROM > 512K)
bit 6 ROM/RAM select (set= RAM)
bit 7 Internal/external ROM select (set = internal ROM)
