It's just a drive in an external drive box w/power supply. Morrow
sold S-100 floppy disk controllers and external drives to go with
them.

It sounds like it is an external drive cabinet.
Morrow had external cabinets for single and dual 8" floppy and hard drives.
Used with their S100 systems that preceded your MD-2 series. I believe Morrow
got it's start with S100 systems.

Anyone know what this is? The main unit looks about like a terminal with a builtin CRT and keyboard and has boards in the back that look simialr to STD bus cards (but I didn't look close). There are two other units, one has two 8" floppy drives in it and the other says that it's an expansion unit.

>I believe he meant 'unlimited users' not 'use'.
PAKs are limited in several ways (not all of which are
used in practice). One typical way was that each PAK would
grant a certain number of "units" for a given product. So
using the FORTRAN compiler on a relatively slow MicroVAX 3900
series box might require say 500 units, while using the
same compiler on a VAX 7000-860 might require
perhaps 10000 units (I'm making up the numbers ...).
Later on, some products switched to activity based licences.
In the above example 500 units allows you as many concurrent
FORTRAN compilations as your MicroVAX can stand. With activity
based licences, your FORTRAN compilation on a certain platform
might eat up 100 activity units so with a 500 activity licence
you could run 5 FORTRAN compiles simultaneously.
Then there were user-based licences ...
In short, it appears that the hobbyist licences are limited
only in time (they expire after a year) but will work without
restriction on both your MicroVAX I and your AlphaServer GS320
during that year.

No, that only covers Model I TRSDOS 2.x and NEWDOS 2.1. Sellam asked
about TRSDOS 1.3, which I have to assume means Model III TRSDOS.

Model I TRSDOS (and single density disks on all TRSDOS-like DOSes that
support single density) uses this format.

I have been trying for the last few days to reach Michael and all my emails
bounce back with fatal errors? Does anyone have a different email address
than these two; editor(a)classictechpub.com and Eletter(a)lyris.dudee.net
Thanks for any help.
> What sort of equipment is this? Old PCs or test gear?
I'll tell once I have it, but it's way cooler than PCs.
Cheers,
Lee.

I'd agree that the current layout is good. Next, I'd go with the fancier
one, but both are _too pastel_. How 'bout some good, saturated colors?

Having looked at all three, I rather like the current, but think it would
look better without the busy graphic below the black CLASSICCMP line. Of
the other two, I prefer the 'retro' one, but would recommend white instead
of pale green.

These are eurocard sized boards with no gold plating.
I doubt there is any gold on any connectors either.

I don't know UK prices but they should be similar to the US. Scrap prices are
similar world over in the developed countries.
In the US, if it is bulky, without many circuit cards the value ranges from 5
cents per pound (motor breakage, must have copper content) (like power
supplies) to 16 cents per pound (Aluminum breakage - mixed Aluminum and other
metals) (like hard drives or computer gear with aluminum cabinets) it is sold
& bid price is calculated by weight.
Aluminum and heavy copper can raise values, especially if they are easy to
remove.
Heavy circuit cards (with relays or metal bracing) are 10 cents to 40 cents
per pound.
Poor circuit cards (Like recent PC stuff) 0 to 20 cents.
Medium circuit cards (DEC, DG & stuff from the 80s) $1.00 per pound
Good cards like (Intel multibus I - 70s, early 80s - lots of black chips,
gold chips, old silicon chips.) $1.50 - $2.00 per pound
Gold plated cards (like HP) $3.50 per pound & up (depends on age)
Cards have to be complete with edge connectors and all chips.
Gold chips alone are $8.00 to $20 per pound and sometimes more, especially
for old military.
Old gold pin backplanes are worth $20 to $50 and up
Good (25 pins in a 25 shell) clipped connectors $2.50 per pound.
This is what the scrap dealer is going to look as bidding figures. There are
deductions for problems related to the bulk of the lot (do you have to rent a
truck?)
Call a scrap dealer that is not going to bid on the lot and ask the prices
for Motor Breakage, Aluminum Breakage, Medium circuit cards and heavy circuit
cards. Also the price of Aluminum scrap, cleaned (this means all iron,
including screws, removed) Much of the value in electronic scrap is in the a
luminum and how easy it is to get out.
Someone else will have to convert to British Pounds.
Good luck and what is the stuff?

Astoria, OR
Ps You can contact me directly if you want help trying to figure out the
scrap value of the lot. I am not going to bid on it. Do you have pictures?
