Specifications

1. Bracket for Miniscribe Drive - Part Number: 0177,001
The item in last issue of the News-letter covering the new brackets that are required when replacing Tandon or
Western Digitial for Miniscribe drives only applies to the Archimedes 440's, or 305's and 310's that have had a
hard disc upgrade fitted. The new brackets are NOT required on the 400/1 series machines.
2. Taxan 770 Multi-sync Monitors
There has been reports of incompatability between some early Archimedes 400/1 Series, the new A3000 and
Taxan 770 Multi-sync Monitors. To be precise, the signal input impedance of the SYNC lines,(VS*, HS* and
CS*), is too low for our output drivers.
The 400/1 and A3000 series has an additional signal present on the video connector, namely "MODE". This is to
provide a "device present" signal to a domestic T.V. when used via a SCART interface.The Taxan requires this
extra signal, if present, to be in a defined logic state. This is then used within the monitor to select screen size. At
the moment, due to the loading of the monitor, the computer can not drive this signal to a guranteed logic state, thus
causing the Taxan to jitter.
To cure this problem.
A400/1 - fit a shunt to Link 2, located near the Analogue RGB socket.
A3000 - fit a shunt to Link 25
This may result in the need to adjust the monitor display size using the controls at the rear. All rear buttons
should be in the out position.
3. EPSON GQ3500 Printer in Laserjet emulation
Rescently we have had reports of problems using the Epson GQ3500 printer in Laserjet emulation mode with the !
PrinterLJ application under RISC OS being driven via the parallel port. When printing graphics, faint white lines
appear on the print out.
This is caused by an incorrectly set DIP switch on the External Printer Interface Card. DIP switch SW4-4, when
in the OFF position strips the eighth data bit which controls graphics output, thus causing the white lines. Setting
the DIP switch to the ON position will solve the problem.
Information covering DIP switch SW4-4 can be found on page 13 (problem solving section) of the GQ3500
Manual.
