Posted by Edwin Blink on the Sam Users Mailing List:

I have some good news too. After a long time I finally have made a CF interface for SAM that comes in a light version of the Atom.

Light meaning it is has 8-bit wide databus. CF-card are accessed in 8-bit mode. So no capacity is lost and speed is even faster. It’s designed in such a way that it fits in the right floppy disk drive bay without the need to open up SAM.

It is also compatible with most existing Atom software (some minor changes are needed in some cases though) for example I didn’t need to make any changes for the Atom versions of Prince of Persia & Lemmings.

Information on the Mayhem Accelerator to be added shortly. (Best place to get all the info just now is in Sam Revival issue 15)

Current Status: Testing of final production version in progress, before commencing with building the first batch!

EDDAC

Peripheral

Edwin Blink


Edwin Blink


Edwin’s parallel port sample player, a Stereo 7-bit DAC that plugs into the Parallel port on the Sam élite, Comms Interface, External Drive Interface or the SPI.

The main application to utilise the EDDAC is the Sam MOD Player

The design was produced into a consumer model called the SAMDAC by ByteDelight.

MiDGET

Peripheral


Rooksoft


The MiDGET started out as a hardware digitiser - as demoed on the SAM Newsdisk 4 .

However, the original version of the hardware would take in the region of 6-8 seconds to grab one frame, which limited it rather for real time processing.

From the start it was planned by Adrian Parker (who at the time in charge of hardware development at SAMCo) to add additional features such as a Genlock.

After SAMCos demise, Martin Rookyard worked with Simon Cooke (and the occasional input/irration from David Ledbury) on a revamped product called MiDGET: Mixing Digitizing Grabbing Editing Technology (or something similar…)

MiDGET would have its own processor (probably Z80 based), and effectively be its own computer which would talk to the host system.

The idea being, that MiDGET could talk to ANY computer, not just SAM… by using a different ‘bridge’.

What was more impressive is that the hardware would be able to be controlled as an external graphics display by the host system… with a resolution in the region of 800 x 600, and around 16 million colours to chose from incding plans for hardware scrolling.

Combined with it’s genlock facilities - this would allow the host machine to control sprites over a MiDGET based background - imagine Sphera on the ZX81 :)

An early demo was given at the April 1994 Gloucester Show to many noted SAM People, including a very shocked Bob Brenchley.

MultiROM

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)

An two port expansion card, like the SamBus but without a clock.

SC_Autoboot

Steve's Software


Steve Nutting


Replacement ROM 3.0 providing automatic ‘F9’ to boot a floppy and much faster reset.

V1.1 also included a partial firmware fix to the Hardware Bugs of disc corruption.

XDI

Peripheral

The XDI (eXternal Drive Interface) is a re-release of the MGT External Drive Interface.

Sam in a Can

Peripheral

Quazar


Colin Piggot


A project from Colin Piggot to fit the guts of a Sam Coupé into a new case, allowing as many peripherals as required to be fitted within the same case.

To date, the most jam-packed Sam In A Can has consisted of: Sam Coupé motherboard, Disk Drive interface, Atom IDE interface, Compact Flash Interface, Quazar Surround soundcard, Quazar Surround Sampler Module, SID Interface and a PC Keyboard interface.

See the Quazar Site for details.
