Thank you, I can make sense out of that unwrapped version
(The only emulator I use is SMSQmulator)

Re: Sinclair QL + QSound demo
"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).

Re: Z88 power supply
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.

Re: Faulty (video) ram
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....

Re: Z88 power supply
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...

Re: Z88 power supply
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

Re: CST Ram Plus eproms - CST QDisc v4 issue
If this byte sequence is used only for 16KB bin files for the Rom slot what about the 32KB rom files? The byte sequence $4AFB0001 can be used for any size ROM files (within available space), not just 16K. AFAIK that sequence was chosen because it was least likely to occur in normal binary files. An...

Re: CST Ram Plus eproms - CST QDisc v4 issue
AFAIK the 68K/OS(32KB) file is a complete operating system replacement so I don't expect it to be recognised by QDOS/Minerva. Though it will be interesting to see if t0nyt's 68K/OS PCB can be realised as a schematic

Re: CST Ram Plus eproms - CST QDisc v4 issue
OK, the first thing to do would be to look at each of the files you wanted to add to EPROM in a hex editor. If they are true QL ROMable files then the format of the first few bytes is defined: $4A,$FB,$00,$01 unique identification word for ROM code $??,$?? offset to list of names of new SupreBASIC p...
