I have thirteen functioning arcade games in my basement. Not completely OT since they all date from the 1980's and have at least one 8-bit microprocessor in each :)
Anyway, try "RGVAC" as it is commonly known (rec.games.video.arcade.collecting). Lots of help there, many posts by regulars, etc. I even got a T-shirt with a RGVAC logo there :)

Thanks Jerome for this information.
I did know what the WRITE PROT button does :-), but the fact
that you can run RT-11 with that button ON was new to me,
as long as you don't need to write to the pack, of course.
Very handy if you make any copy from the system disk to an
other disk. An error in the entry line (DL0 <-> DL1: swapped)
will not be harmful to the system disk with the WRITE PROT
button ON. I used your tip yesterday!
I did notice however, that I became a little less "on guard",
because I was thinking "I'am safe" :-)
BTW, as you can guess, my problems with the RL drives that
would not boot are solved. The drive(s), cables and the pack
are all fine, the RL11 controller developed a fault.
I have tagged the board with a label that describes the
symptoms and put it aside ... for days when I have more time
to do some fault finding on the board; when I'm retired :-).

Hello everybody,
I can get an old Honeywell type drive. But I know literally nothing
about it. Not even the model number...!
Here is a link to a few pictures I've received today:
http://hachti.de/honeywell-tape/
All I know about it is that it has the colour and same switches style
like my Honeywell H316 computer. Perhaps I could use them together?
The tape was originally connected to a machine called H632.
So I ask for every information known about this tape drive. Perhaps
someone has software, schematics etc.?
I would be grateful for every little piece of material/knowledge!
Thank you very much,
Philipp :-)
All - My SGI workstation (which I use to create stuff in Blender, altho the
rendering
is done elsewhere for speed ;) just emitted the smoke of life from it's
power supply.
I'm looking for SGI P/N 060-8002 or the stronger 060-0027 (Zytec p/n
22928805).
The only sources I could find with Google are 1) out of stock or, 2) $700.
TIA

All:
I was searching my copy of the CPMUG archive for something and I
discovered that I have a bad archive file and a few missing ones. I don't
know if the missing ones actually exist, however.
Here's what I'm missing and what's a bad ARK file. CPMUG040.ark
is bad. I'm missing 039 and 055-077 (don't know if these exist). I tried the
usual on-line places and looked in the WC_CDROM and these aren't there.
Please contact off-list if you can help. Thanks.

The good news: Dave Dunfield has made some changes/additions to ImageDisk
(now version 1.09 and copyright 2006), so it's officially not an orphan.
:-)) Whoohoo!
Thanks, Dave!
Now the bad news: I thought I could "cheat the system" by running ImageDisk
on Windows 2000, as I have some Tu^H^HWordPerfect 6.1 disks I needed to try
to image. Yes, Right there in program documentation it says it won't run
on any Winders OS that uses good ol' HAL - that's the Hardware Abstraction
Layer for y'all that run the "good" OS's. ;-) Well, I tried to run it in a
Winders98 install under VirtualPC under Winders 2000. I was hoping that
VirtualPC would open up the HAL enough on floppy access to allow ImageDisk
to do it's job. Well, it still didn't work. It tried awfully hard, but the
HAL just confused the bejeebers out of it. (At times, ID thought it was
reading a Single Density disk!)
This is *not* a dig on the program, I *knew* I was asking way more than I
should at the beginning. I was *hoping* to have good news if someone
wanted to run it on a newer M$ OS that didn't suck nearly so bad as WinME.
I guess I'll have to dig my old smellyron (er, celeron) 533 system out of
mothballs which runs 98 & install/run it on there. It's just that I'm a bit
space-limited right now, and convincing the wife that I need room for a
permanent CoCo setup *and* yet another IBM are slim (and at this rate,
there's *no* chance for a little space for the Amiga 4000T in the near
future... :-/ ).
[[ Yes, I know there's a rawrite utility for NT. Yes, I've already tried
it. Yes, I'm getting CRC errors. No, I'm not going to swap 12 floppy drives
around hoping to get one that can read 'em... :-/ ]]
Ah well, ya can't blame a guy fer trying, eh? ;-)
Thanks again, Dave!
Laterz,
Roger "Merch" Merchberger

The ISE is needed to mount the DSSI disk. VAX 4ks in the BA4(30/40) have a sled arrangement with a card edge connector bringing out power and DSSI. I've been looking for one for a while, and most of the E-Bay DSSI drives are stripped from the sleds (don't know why, I guess earlier MicroVAXen didn't use the sleds). The KZQSA will work in a pinch provided that you want to run VMS, none of the xBSDs offer support for it (ULTRIX doesn't even work well with it) Performance will likely leave something to be desired. I've seen docs for a HSD that mounts in the BA4x0 and allows for SCSI in the upper bay, but have not seen one in the flesh. I'm currently looking to wire a HSD05-AA SBB in mine, but it still looks like I need a sled or two for mechanical connections :(.
