    OK, so I've been a very busy boy since I last posted in this thread.

    It seems this thread has picked up a bit of steam so I thought I'd post some more of my thoughts on the PC-SPRINT and see if some of the more technical people here can enlighten me on some of the...

    Fair enough, I'm still learning when it comes to this stuff. It seems that faster is not always better. I'll try to see if I can find some of the articles you mentioned. Yet another data point to add...

    This mod adds a separate timing crystal and 8284A oscillator chip specifically to clock the CPU. It would be possible to overclock the whole system by dropping a faster crystal straight into the...

    My next system up from this one is a 486 DX4/100 which seems a bit too new for this type of mouse. I don't need too much of an excuse to add a 286 to the lineup, however... ;)

    Hey again. I'm really interested in trying out this upgrade so I sent your gerber files off to PCBWay to get some boards manufactured. Hopefully that's the reason you shared them! I really do...

    Thanks everyone. I hadn't even considered a serial mouse despite already owning a few. I guess that settles it.

    Still happy to own this unusual piece of hardware and will try it out anyway just...

    I'd also be interested in one of these. I have no experience in getting PCBs manufactured - if I send the KiCAD files off to a PCB fab service will they know what to do with them? Alternatively is...

    Funnily enough I was looking into the 5161 just today. The 5150 just doesn't have enough ISA slots for all the stuff I want it to do!

    No problem at all. It seems I'm misremembering in fact. I've just double checked and mine does indeed have a modulator despite being branded on the box and the case as just a "520ST". Though oddly...

    For what it's worth I have a PAL unit that has this exact same modification - minus the connection to the modulator (it doesn't have one). It's an early 1985 model running TOS 1.00.
