Hello. I'm actually working with one Microvax 2000, one Microvax 3100
and one RZ55 SCSI external enclosure with one 359 (more or less) SCSI
disk inside. I have installed VMS 6.2 in the Microvax 3100. I've backed
up the VM6 6.2 in the SCSI external disk, and I'd like to try boot this
disk from the Microvax 2000. Until I know, is necessary to modify the
EPROM with a patch that I have. The problem to do it is, of course, the
WAY to do it. And this is the matter:
* How can I update/patch the EPROM of one Microvax 2000 from version
1.2 A to version 2.3 (I think this is the version of the patch) to
support SCSI bootable devices, like one installed in one RZ55
external enclosure ?
One additional matter about this question is:
* Exists another patch that allow to boot the system from one RDD40
external CD unit ?
And, like a possibility to obtain some money:
* I need one CADDY for my DEC RDD40 external CDROM unit.
Is there anything out there ?
Just by the way... Anybody knows where I could obtain this stuff for
the 2000 ? That is:
* One diskette unit (I think it goes inside CPU, but I'm not sure, and
additionally I'd like to know, what happens then with the RD54 disk
that comes inside it actually)
* One external expansion box with one additional RD5x disk. I think
it uses something like one SASI connector to plug into the 2000.
* One additional RS-232 ports expansion unit. I've read that it provides
the Microvax (or Vaxstation) 2000 with up to... Four / Eight ?
additional comm ports.
And finally, there is for Europe collector/sellers: I'm searching
this stuff:
* one DSD400 or DSD880 double 8" disquette unit
* one RL02 disk unit (I have six RL02 cartridges ready to use)
* one VT102 with interface cable BCC08 or similar
* one TU58 tabletop tape unit with interface cable BCC08 or similar
* TWO interface connector with one Female AMD 10-pin connector in
one extreme, and one standard RS-232 9-pin in the other.
Anybody knows/has/sells any of this items at reasonable prices,
or simply legate them ( :-))) what innocence
mine ... ) ? You can send the responses to my e-mail address
if you consider it better.
That's all for know. I'll agree a lot a response. Thanks.
Greetings and best Regards from Spain

I'm in the same boat. I have ancient ROMs, the same patch you probably
have and a patched 32-bit file that isn't split up into 4 parts. I got
a ROM splitter routine from somewhere and did the cut, but without
sitting around and switching out ROMs from socket to socket (at least one
of the pins on one is starting to go), I'm stalled. Maybe if I installed
four ZIF sockets...

You can't have a floppy drive and a full-height hard drive in the same
box. I don't know if the PSU could take it, but there's room for, say
an RD-32 (ST-251-1 @ 40Mb) and an RX33 (Teac FD-55-GFR) in the same box,
but you might have to modify the internal bracket.
* One external expansion box with one additional RD5x
disk. I think

It's a DD50P, like Sun used to use with Sun3-era SCSI. You have to have
this extra expansion skirt at the bottom of your MicroVAX 2000 that
houses a small circuit board. You would also need a corresponding
external RD54 enclosure for the other end of the cable. It's MFM signals,
over a single 50-pin cable.
My first uVAX 2000 had the skirt - it came with two RD54 drives and
a DHT32 serial expansion. I got the box because the client asked me how
much it would cost to double the number of terminals in the office.
I gave them a quote and they asked me how much they could get for the
system. They wanted 3x what it was worth, so I waited and a year later,
I offered them _half_ of what I'd offered them in the first place and they
took it (the astute reader will note that they got 1/6th of what they
originally wanted; I think they originally asked about $2000 (this was
many years ago - they replaced the uVAX with a Novell network of DOS
machines) ISTR paying them about as much for the entire system as an RD54
drive sold for retail at the time. Oh... that included 6 VT320s which I
sold to a DEC reseller on the way home from the client. I think my out-of-
pocket cost was under $200 for what I kept).
* One additional RS-232 ports expansion unit. I've
read that it provides
the Microvax (or Vaxstation) 2000 with up to... Four / Eight ?
additional comm ports.
Eight. It's a DHT-32. Very rare. You are probably better off trying to
find a terminal server. It's not the same, but they are more common. I
never got mine working because the 36-pin interface cable and the harmonica
were apparently left in the ceiling when they moved during that year they
sat on the machine. I got a cable and what I thought was the right
harmonica, but apparently I am mistaken. Does anyone have any docs on the
DHT-32?

Get a MV2k with PROM 2.3, read the EPROMs, burn new EPROMs
and put them
into your vers. 1.2 MV2k.
* One diskette unit
You can use a generic
PeeCee floppy. I connected a Mitsumi D509V3 and it
just worked. See the well known third-party-disks.txt also.
(I think it goes inside CPU
Yes. But you can
crimp a new, longer cable to put it outside the box.

There exists a
pizza box that is screwed below the CPU box. It contains
only connectors for a external RDxx disk and the "SCSI" tape port.
Again: You can crimp your own cabels and route them through the
opening at the bottom of the MV2k. I did this to connect various RDxx
disks "on the fly" for low level formating.
