A latecomer, eH? I started on a 780...before the 750 existed!

Well, i've worked on all the early stuff TBH, the only thing i didn't
touch was a PDP/11 or a MicroVAX 1. Had a MicroVAX 2 though !

Got a uVAX I here that I'm working on 'cos either its RD52 or RQDX1
has gone south

RD52 !! a very small scsi disk IIRC. I replaced the DEC firmware'd
disk in mine with a standard (bigger) SCSI disk. The Tagged Command
Queuing on the bus really confuses the hell out of the uVAX, but it
doesn't crash it...

The RD5x disks were ST506 (MFM) drives. The 52 is a whopping 31Mb. I
recall getting an early Pro 350 to play with - RD50 with 5Mb all for me;-)

I worked on PDP-12s back in the 1970s (the PDP-12 was a combination of
a PDP-8 and a computer developed by some university in the US). That
had a whole full height 19" cabinet dedicated to a 256k hard disk,
four platters if I remember, each with 128 heads.

I've got to find a way of backing up the RD50 in my Rainbow 100B+ 'cos
I don't have install media for it.....could always use a load of RX50s
I suppose.....

You'll only need about a dozen :-) Ah, the days when you really could back
up your hard disk onto floppies...

I'm an ex-RSX-11M (Systime) programmer. How come I'm not a hero of
yours?

No, *I'm* the ex-RSX-11 programmer. DNC wrote most of it. And
reportedly ported 11-M to the PDP11-70 over a weekend when the other
O/S development teams were saying it was going to take months.

Oh, and SYSTIME kit sucked donkey doo-doo.

But they did have a blue carpet with the Systime logo, an indoor
fountain (always a give-away sign of impending financial disaster) and
helicopter landing pad for ?John Gow

I think the person who originated the theory about corporate excess and
imminent liquidation had probably visited Systime's HQ. Just south of
Leeds, iirc.
