Hi folks,
I recently picked up a DIGITAL RM80 drive.
>From what I've read, this is a SMD drive based around the R80 HDA, with a
massbus to SMD bridge.
I have identified this component and the outputs indeed look like SMD.
Is there a way to use this as a SMD controller with 3rd party drives?
How would you format or set geometries?
Does anyone have more information about the RM80?
Thanks,
- Ian

Do you have the dimensions on that belt handy? All of my Commodore
tape drives are erratic due to aged belts. I can't get good reads and
I have some PET Rabbit-format tapes to read (long ago, I digitized my
standard CBM tapes).
I'll likely order from this side of the pond, but I just need to know
what size(s) work(s).

Hi all,
A while back I asked if anyone knew how to open the case of this early
luggable, and there were crickets. Well, I pulled it out today with the
intention of poking and prodding, and I magically got it to open!
There's a top piece that is fastened to the front bezel with two apparent
screws. But it is also snapped in to the rear cover in a manner that is not
readily apparent or discernable. If one removes two screws at either end of
the rear cover, the rear piece will cantilever back ever so slightly, and
the latching of the plastic pieces will separate without damage.
The power supply assembly is fastened to the bottom of the case with a
couple of screws that come up from below/outside, so I'd already removed
those. It should be relatively simple to rotate the assembly so that I can
remove the screws holding the PCB to a backpiece, providing access to the
PCB so I can replace the 30+ year old electrolytics. Given the symptoms,
this seems like the most likely root casuse.... -- Ian

Over the past six months or so, I've been selling install floppies for the
Xerox 8010 Star. I had no idea if I had a full set or not. I'd just put
together a set of as many unique floppies that I could find from my stash.
Then last week I was asked if I had a full set. This person then stated
that Al Kossow might or might not have a full set. In any case, it's not
on Bitsavers. Al expressed interest in a set that I offered a couple
months ago, but he never followed up on that. So, would someone please
confirm the existance of a full set of install floppy images for the Xerox
8010 Star somewhere?
The floppies I have left are these:
ViewPoint 1.1 (file check)
ViewPoint 1.1 (essential applications)
ViewPoint 1.1.6 Common Software
ViewPoint 1.1.2 Local RS232C Communications Access

I'm sure I read of someone who was implementing an entire CPU as discrete
components on an even larger size... there were racks of the thing; it took
up most of a room.
But I can't find the link....

I would like to get a Tek 4404 computer going but lack any service
manuals. The system turns on but has no curser on the screen. Has
good power from the Power supply and heater is on in the CRT.
Has a row of LEDs on the mother board. Does anyone know how
to read these.
- Thanks, Jerry
