It's a later Issue 5, build standard D11 thru D14.

Aaaand, nope. One of the parts I was shipped they sent a part different to the spec they listed. So, the correct parts will be here on the 16th So, I'll announce something on the 11th, something on the 18th and something on the 25th. One item a week. That takes the pressure off. The first thing will...

I would like this add-on to be standalone and not require users to open their cases or modify their Q68s.

With Peter's assistance via email, a solution has been found. I'll power the device externally using a simple micro-USB port. Cheap, ubiquitous, small.

Good job.

The VL1772 are far more reliable double clocked than the WD1772. That's why I bought huge stocks of them for the SQBv4.

Sorry, only asking because my Q68 is being manufactured, so I don't have one to just ask.

In the manual it says pins 4 and 7 are pulled up to power a PS/2 mouse. What voltage are they pulled up to? How much current can be drawn from these pins to run external devices like mice, serial adaptors, etc? Are the pins linked internally, or pulled up separately? I'm looking to draw 150mA @ 3v3 ...

I might just make the deadline!
Just one batch of ICs that needs to get here that might not make it, and is kind of critical. I can probably get them locally.

You'd just need to remove the HD power connector, because it's duplicated in the floppy power connector.

Would you be interested in emailing privately?

If you replace those IDE connectors with right angle connectors, they'll go the right way up too.

I apologize in advance for trending close to off-topic. On an emulator I get little benefit, but on the BBQL I often copy floppies to ram disks because there's a significant speed-up, and if I am playing with large datasets that I manipulate directly, like a database, I find it much quicker and quie...
