Radius HPV Card?

[macuserman]

Is there any difference between this card and the Apple Card other than branding?

They look nearly identical but with some slight differences. Probably the same but just wanted to ask.

I would imagine that was probably the HPV card that shipped with the Radius 81/110 clone.

I kinda figured, do you know if there is any actual difference though other than branding? I plan to hang onto it just because it's funky, but I was curious about specs.

It's a 2MB/4MB card, so equivalent to the 8100 card, not the 7100 card.

I can't imagine there being any practical difference because they were just plain, fast, 64bit framebuffers. Speed through simplicity and efficiency, rather than quickdraw acceleration.

Figures, well I'll stash it aside until the lucky day when I actually find a Radius machine. I've been hunting but that is a unicorn for sure.

Would that work in a 8100?

Yeah it works in an 8100,7100, and 6100 if you have the 90 adapter.

6100 if you have the 90 adapter

HPVs with VRAM SIMMs don't give proper clearance to a spinning hard disk, and for some reason are also unreliable in that they work in some 6100s, but not others. HPVs don't work in my 6100

I have seen other people use them though.

AV card works just fine

Huh I did not know that, good to know, ZuluSCSI would probably create the clearance, but not solve the reliability issues. I read somewhere about there being two different versions/part numbers of the HPV card I wonder if that has something to do with it.

The main two versions are the version that takes up to 4MB and the version that takes up to 2MB (each having half this unpopulated).

I have to admit I might only have 4MB cards...

OOOOH! I SO NEED ONE for my 81/110!

HPV is a very fast 64bit buffer, but the A/V card compatible with the 6100 (also 2MB VRAM) has only a 32bit data path. That makes HPV 1/2 a big improvement over the A/V card if stuck with only a 6100 as your graphics machine in that NuBus PPC era. HPV 2/4 makes for more-n-better pixels to play with on a big CRT.

While the HPV card does conflict with the cubic of the 3.5" OEM HDD in the 6100, if you've got it (and adapter) just go ahead and install it. Run from an external HDD. 2.5" laptop drive would "work" internally, but have silly limitations as compared to 3.5/5.25 inch platters. No fast/narrow bus in the 6100, so external storage is no bottleneck.

Cooling is a known consideration for running HPV in a 6100 with G3. I've been setting up a 6100/G3/HPV on and off for a few years now. Cooling mod 2.0 underway. First notion wasn't radical enough a departure from stock cooling to bother with.


edit: wondering if Radius was the OEM for HPV as they were for 24AC?

 

[dramirez]

I may have a 7100 HPV card available.

Sounds like you need me to take it off your hands. Lucky duck I’ve been looking for one for flipping ages.

Not sure about that I’ve heard rumors of a power computing version that had vga on it. But I can’t find much regarding its details and no pictures.

@trag may know a little something about that? ISTR something about that PC version having the HD15 connector? Dunno, surprised Radius didn't do it that way. But then again, their version of the 8100 board had an Apple standard DA15 connector on its backside instead of that horror show of a thing in want of an adapter sticking out the back. That and the fact that cubic is available in its case to install HPV without giving up a NuBus slot puts the Clone#1 from Radius head and shoulders above the crumbling Apple messes.

Radius was the first Clone licensee and I've had the beautiful Big Metal Can I'd lusted after in the day for over twenty years now . . .

. . . may just have my ashes buried in it!

Just let me know where you plan to be buried so I can “pay my respects”

 

[Trash80toHP_Mini]

HEH!

No pictures? One in and cracked the can open to spill the goodies out onto the side panel:

Yes, the Power Computing Corp. (PCC) version of the HPV card, which shipped in their Power 120 (also Power 80 and Power 100, although I've never seen those two and think they're mythical) had the modification shown in jt's later photos.

PCC added a PC/VGA-style HD15 connector and a switch to select either the Mac style output of the PC style output. Only one connector could be used at a time. It was not a dual video card.
