Arrgh. Dyson DC01 poorly

Whatever. I remember thumbing those plastic toggle switches on the PDP8 to enter the program. 12 bit words as I recall.....

Sending email to my published email address isn't guaranteed to reach me.

Yes....shades of yellow and brown on a PDP-8, red/maroon an a PDP-11, blue on other (e.g. PDP-10 and 15). I have a picture of the toggle switches on a PDP-10.... 36 of them, all in a row!

The you'd get to the last but one and realise the you'd made a mistake.

To email, substitute .nospam with .gl

That's not too bad, though laptops make good secondary PCs, the two here run at 20w and 12w :)

cheers, Pete.

Yep. I have a VaxStation 3100 M76. Powered it up the other day and was amazed I still remembered the command $MCR AUTHORIZE ;-)

Cheers,

Paul.

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...

Cheers,

Paul.

They are indestructible ! the one I managed refused to die. Does yours have the vast capacity (!) TK50 in it ?

Cheers,

Paul.

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...

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.
