I thought that the QIMSI Gold needed to be plugged into a QL to work, but you show it as a stand alone computer. Is it really the case that it can be used without the QL, as mentioned by PrOF? The FPGA inside QIMSI Gold is in fact running a Q68, so it can be used as standalone computer, but of cour...

Which firmware has the MicroP controller, the original (with FDK device rather than FLP) or the replacement QJump?

After installing Minerva the QL didn’t boot anymore, before the selection F1/F2 it halted and showed big black and white horizontal stripes, 9 black and 8 white and after inserting the JM ROMs again it is still the same, see attachment. Does anybody have an idea whets wrong? How did you install Min...

The original specification requires that you compare address lines A14 to A17 against pins SP0 to SP3, and A18 and A19 should both be high, to access the bus. SP0 to SP3 are the Select Peripheral pins, which are all tied to ground on the QL's edge connector, hence your peripheral will be at $C0000 w...

The Jan Jones book (Quanta issue) does not fully agree with your picture. Stipple 0: Top Right is contrast Stipple 1: Bottom two are contrast Stipple 2: two Right-hand are contrast Stipple 3: Top Right & Bottom Left are contrast So Jan Jones is right and the QL manual is wrong, at least with QD...

Actually, both QDOS and Minerva have stipple patterns 2 and 3 reversed compared to the figures shown in the QL Manual (and QPC Concepts guide) under 'colour'. In stipples 1 and 2, the white pixels are background colour and grey pixels are contrast colour. But in stipples 2 and 3 they are reversed. U...

Not even $ instead of £? The ASCII code 96 for £ was something specific for British-made computers. Apart from Sinclair, only the Acorn machines used it as far as I know. On standard ASCII it should display as backquote (`). So the backquote sign is not available in QL ASCII. Back in the '80s there...

QLTerm does not know anything about Hayes commands and responses. It just forwards them to the display and from the keyboard. So if you set the baud rate in QLTerm to 9600, it will stay at 9600 regardless of what the modem reports. Of course, your modem should not change the baud rate once connected...

If you don't have a Moxa but do have a PC you can use the telnet.bas program from my QLTerm repository (https://github.com/janbredenbeek/QLTerm) on any TCP/IP-enabled emulator such as QPC, Qemulator, sQLux or SMSQmulator. On SMSQ/E you'll even have 8 colours available. I'm not sure why XMODEM transf...

It's different depending on which system you're running. QDOS: No easy way, you could try stuffing an LRUN command into channel 0's keyboard queue (this of course only works when SB is idle since it cannot multitask). Minerva: Start an instance of MultiBASIC. The details are in the Minerva manual. S...
