A friend of mine locally has happened across a PDP-8L in unknown shape. He
wants to sell it on eOverpay. I wish to prevent this. To do so, I need to
present to him a reasonable price that he can sell it at. The last -8/L
I got was a rescue. The one before that was $200 in a 6' rack with high-speed
paper tape and 12Kw of core (plays papertape Star Trek beautifully ;-)
I have no idea what to tell him. He is a geek, but has no interest in
preserving history. He just wants the money. Can anyone here cough up
a reasonable estimate of what a PDP-8/L is worth? I realize that it's a
tough question, but if I don't have an answer, some core-collecting weenie
is probably going to have a trophy to nail to the wall.
If it's worth more than I'm willing to pay, I'll gladly help anyone on this
list with aquiring it. The machine is located in north-central Ohio, but
the owner drives to work in Columbus every day.

Hello, I have a VAXstation 4000 VLC with 24mb RAM, no HD and by itself for
sell or trade. I found some basic specs on it and it maxs out at 24mb and all
six RAM slots are filled. It is very clean and powers up OK - that's all I
can check. Please respond directly to mtpro(a)aol.com and thanks! Best,

Or - maybe you didn't :-(. The MVII diagnostics are worse than useless.

Then you didn't format the RD54 successfully. The best you can hope
for with the MVII diagnostics is to turn an already formatted RD54
into a formatted RD54. The worst that can happen is that you
lose an already existing format.
Let me know what media it'd be useful to you on, and I'll get you a
bootable XXDP disk/pack/cart/tape with ZRQC?? on it.

Yep - you need to really reformat the disk, as opposed to what the MVII
diagnosics do. And congratulations on actually posting the command
you used and the error message that resulted!! If only everyone else
on the list could do the same, it'd be a much nicer world!!

So you might believe, until you read the minutae about RX50 formatting
support in the RT-11 5.7 release notes :-). I most certainly have
formatted RX50's under RT-11 5.7...

I have a SCSI card I was given and I'd like to find data or info
to use them. There is no question they are SCSI from the chips and
connectors.
The boards appear to be MTI QTS25 (viking marked on one Eprom). Standard
dual height dual width.
I'm hoping they are MSCP as I play to try them.

You cannot unless you write your own utility.
<(disk & floppy are on RQDX3 controller)
You need the XXDP diag for that.

<i get "device not supported, ...)
I sounds like the Viking series. Zane was kind enough to post a few things
I scanned which includes an OCR of the Viking manuals along with a few gif
scans of pages that the OCR did not keep lined up.
Feel free to contact me off list for more info.

Depends on the PAL that is installed. The markings are as follows:
QTO= Tape only (TMSCP)
QDO= Disk only (MSCP)
QDT= Disk and Tape.

I just formatted the disk in a MVII with the diagnostic tape.

You need the ZRQC?? formatter on bootable XXDP+ media for your machine.
Do you have a RX50 floppy? RX33 floppy? TK50? RL02? RX02? I can
get you the formatter on just about any media... (it *should* have shipped
with your machine in the first place, but someone may have misplaced
the disks at least once in the past decade or so.)
Alternatively, if you have a VS2000, it has a RQDX3-compabitle formatter
built into it.
>P.S. Booting from DU1: works, so the controller & driver should be OK.
>Trying accesses to DU0: I see the LED of the disk drive on.
What error message do you get when you try DIR DU0: ? If it's a
"?DIR-F-Error reading directory", or a "?DIR-F-Input error", then you probably
do need to low-level-format the drive. If you get a
"?DIR-F-Invalid directory", then you probably only need to INIT DU0:
to make it usable.
