The Sinclair QL Forum

Surprised the QL still worked with address lines extended 50cm even without PIC connected, I would have at least used buffers.

BTW I bought these DIN41612 female R/A connectors a while ago and they were OK:

Just normal 41256 drams (256kx1)

Feedback is positive, £6.22 for 10 (VAT+p/p included).

If your PAL is the RAM version it could do with being copied, over the years a few people have wanted this for 0K boards.

Thank you, I can make sense out of that unwrapped version

(The only emulator I use is SMSQmulator)

"It requires Stock QL"

OK, I'll bite. WTF is a ql68k.mdv file? 170.8kb

I've used a QL since it they first came out, never known such a file - it ain't stock AFAIK. Or is it meant for an emulator ? How would such be transferred and used on a real QL?

Don't recall seeing link to this: Interesting perspective from engineer who worked at Sinclair (web archive appears to have retained more of the images).

Measured my Z88 PSU. Off load was 6.34V, with 27ohm resistor load 6.25V at 210mA. Z88 load (+128K rampack) was never more than 100mA.

Looking at the display it appears that (other than green/magenta stripes) the random pixels are placed exactly where Minerva normally shows fault report. So Minerva is trying to report a RAM failure. But surely only one 4164 fails at a time? This looks like something more than a single chip failure....

Just had a quick look on eBay for Z88s and accessories, feeling a little nostalgic after getting rid of my Z88 some years ago. Like many retro systems, the prices they go for somewhat amazed me! I occasionally look at Z88 on Ebay and it does appear fickle, some long standing listings are pricey but...

Ideally you want one with an LED. I added one to mine since it was too easy to be unaware you were running on batteries and the mains switch wasn't on
