The Sinclair QL Forum

... for anyone who's looking for a truly standalone Microdrive hardware emulator that simply needs a QL to get it up and running. Actually, OqtaDrive + a Raspberry Pi is truly standalone. The last missing piece is controlling it from the QL/Spectrum, but for that I already have a few ideas. Hi Alex...

Great to see such interest in the humble Microdrive with some new emulation hardware on the scene! Was a bit disappointed though, I must admit, that on reading through the source, I couldn't find any 68000 assembly code anywhere ( and I thought this was a retro project ...) Full discosure: I'm the m...

Do chips actually turn out to be defective out of the box? Never had this problem myself but then I only had pretty low volumes. Also, I tend to try to get my boards pre-assembled, so checking them beforehand becomes difficult ;) Unfortunately, due to the global chip shortage, there are very few (o...

A bit late with the post but thought I'd add that occasionally new components do fail. I do test all main components such as CPLDs prior to assembly and fully test completed units before shipping but there will always be a small number of random failures soon after installation (anyone remember the...

Hi Dilwyn,

I have managed to get the correct rom image (attached). The QDOS version is 1Y13 and the ID returned by PRINT VER$ is 'MGB'

Cheers,

I don't suppose one of you could supply a copy of the ROM for preserving? I've not come across this one before. Don't even know its copyright status (assuming it was privately produced). Hi Dilwyn, I have a copy (attached) but I'm having trouble getting it to run on Qemulator (the MGS rom works fin...

I have a customer who has a QL ROM I've never come across before (Dilwyn's site doesn't mention it at all). PRINT VER$ gives MGB and the language is Swedish. I'm guessing it's a variant of the MGS ROM but has quite a few differences (from a code diff - I haven't invetsigated further). Does anyone he...

I think gertk stopped working on this due to time constraints back then. According to the document history of the vDrive manuals (ZX & QL), they were first released in 2017. Not sure about the firmware lineage though, since it's closed source. The vDrive was developed from early 2015 through to...

Hi, I've also replied on SMR. In the meantime I'll need a few details: 1. QL board issue 2. After the format failure, enter VINFO and report if there is any error code listed 3. I expect this has already been done, but check the cable and clean the connectors. 4. Copy a known MDV image (you can get ...
