Re: Speaker replacement

Hi,

Just unplugged my speaker and mine measures 39.5 Ohms. So fairly close to 40 Ohms.
This document claims that the speaker is 60 Ohms. Which does not sound like a standard value to me.

Re: QIMSI Gold enclosure


Amazing job, Marcel! By far the most professional QIMSI case design yet! :D
Despite being a senior QL hardware designer, I didn't hear the term "Standard Dupont cable" yet.
Does it mean more than just "jumper wire"?


Well that seems to be the official name. I think DuPont is the original ...

Re: QIMSI Gold enclosure

Thanks Derek and Dilwyn!

As a side note, I have got a few left. Including the correct screws.
So if anyone doesn't have access to a decent 3D printer, gold filament or the screws, send me a PM.
Happy to send one for free, as long as you pay for shipping.

QIMSI Gold enclosure

I'm late to the party, but I got my QIMSI Gold a few weeks ago. My first jump into the new QL era :D!
I found some nice designs online for an enclosure, but what I was missing was the option to be able to access the serial port and I/O without removing the enclosure. So I added slots on each side ...

Re: QL resurrection - worth it? A: YES!!!


I'm happy to report that my QL resurrection has been a success! I have one working floppy drive (which is strictly off-limits to my old disks, which finally wrecked my other floppy drive, despite lots of head cleaning with cotton buds and IPA). And now having re-felted a number of microdrives, I ...

Re: 2. International Sinclair QL meeting in Dormagen (Germany) 6.6 to 8.6

I will be attending as well. And I will be bringing a few QLpicoVGA adapters with me.
By the way, is anyone flying into Dusseldorf on Friday as well? I am planning to take a taxi, so sharing one might be an option.

Looking forward to the meeting!

Re: Protect QL Expansion Port Pins?


I'm struggling to find the 41612 connectors that are compatible with the QL and expansion cards

Most of the ones I find are listed as 64 pin but seem to have 96 holes (for the female) and males have the 64 pins spaced for 96 pins so I don't think they'll fit (at least that's how it looks to me ...

Re: resurrecting one time the original rom plus kludge


Sorry, took a while to respond. The Alea boards don't work with 3x 16k ROMS, see:

I'm sure he'll modify the files so that they will work. If you have the boards already they can be altered.

I can confirm that the repro boards do fit inside an original ...
