Picture of a Q68 motherboard

Last Updated: 30/04/24

This page is dedicated to the Q68 Sinclair QL successor motherboard designed by Peter Graf. The Q68 includes a 68000 compatible CPU, graphics, peripherals and sound on a single integrated circuit. It can be fitted into an available case and does not require parts from an existing QL. The Q68 uses a pair of SDHC card drives and has both QL display modes and high resolution/high colour modes.

If anyone would like to make available any more software, documentation, or articles about the Q68, please email it to me.

Q68RTC100.zip (19K) - An Easyptr4 program that is a Real Time Clock utility for the Q68. And only the Q68. It allows you to manage the Q68's backup RTC, and reset the backup IC's registers should they get corrupted. The program has been compiled with QLiberator, and just needs the QLIB_run runtimes installed. (Martin Head) [03/02/23]

QoENet045.zip (401K) - an Ethernet driver for the Q68's built in Ethernet port. It supports UDP and TCP ports. It also supports DHCP and DNS protocols, ARP and Ping. QoENet045 fixes problems in End of File handling in IO_FBYTE, and IO_FSTRG on IP channels. (Martin Head) [30/04/24]

Remember also about Martin Head's IPNet, Ethernet network driver, available from the internet and email page.

ndq68_v305.zip (56K) - driver software that allows you to network the Q68 with other QL-compatible machines via the standard QLNET ports. Sources included. (Martyn Hill) [20/06/19]
To use the network on the Q68, a small hardware modification is required, consisting of a couple of resistors, a 3.3v Schottky diode and the 3.5mm Jack socket(s) to allow physical attachment to the QLNET. This modification is described in a simple schematic which appeared on the German QL Forum: qlnet.pdf (123K)

In this way, they can also be used on the Q68 with the MDI software installed as ready made games packs.For those who use Martin Head's MDI microdrive imaging driver software, Derek Stewart has kindly converted some sets of ".MDV" format games, intended for use with the vDrive for QL (plus usable with the QLay and Q-Emulator emulators). Get these files from the vDrive page.

Q68capslock.zip (5K) - a short SBASIC program which monitors the Caps Lock status and switches off/on the yellow front panel LED on the Q68 as a Caps Lock indicator, since the Q68 doesn't implement the caps indicator LED on attached keyboards. Note that the Q68 network can use the yellow LED too, in which case you may prefer to use my GD2 Caps Lock Sprite indicator routines available on this page instead.

The latest version of SMSQ/E for Q68 can be downloaded from the Wolfgang Lenerz site at https://www.wlenerz.com/smsqe/
