Re: Rack-mount or tabletop version of DEC RX50 floppy drive?

I don't recall for certain, what floppy models were done as externals for the DecMate I or II, but I think there were both RX01 and RX50 boxes as described. I don't recall hard drives til the VT278 desktop box. bb On Tue, Oct 2, 2018 at 8:32 PM Ethan Dicks via cctalk wrote: > > On Tue, Oct 2, 2018

Re: Rack-mount or tabletop version of DEC RX50 floppy drive?

Thanks to Josh, Ethan, Bob, and Adrian for confirming that there were rack and table-top RX50 drives. It would be nice to get one since I have an RUX50, but having never seen one before, I won't hold my breath. It would also be nice to find the RUX50 manual and print set.

I'd recommend contacting one the guys at https://pdp-11.org.ru/support.pl?lang=en Since Russia is twice the size of the USA, do we know where the machine is located? -- Jeffrey H. Johnson j...@trnsz.com https://ban.ai/multics > On Oct 2, 2018, at 8:37 AM, Jay West via cctalk wrote: > > Some

Looking for HP 1000 A990 backplane jumper board and memory frontplane

I have an HP 1000 A900 20-slot box with a working 4 card CPU set (sequencer, data path, cache control, memory controller). I also have a 12990-60102 A990 CPU card that would replace the 4 A900 CPU cards and install in place of the A900 memory controller card. What I don't have is the 12990-60020 j

Re: Looking for HP 1000 A990 backplane jumper board and memory frontplane

I remember you mentioning wanting one of those when I got my 1000 A900 kit, Glen. I don't have a spare but I'd be willing to take some photos and measurements of mine, if that might help somebody to make one. -- Robert On Wed, Oct 3, 2018 at 2:31 PM Glen Slick via cctalk wrote: > > I have an HP

Bluebox AVR boards available

I've finished my work on designing and debugging a PCB to go with my AVR-based bluebox program. Read about it and buy one at https://661.org/proj/bluebox/. This project implements a bluebox in C on AVR microcontrollers. This project is roughly a reimplementation of Don Froulas's PIC-based

Ethernet names...

I was there and it was always called "The Ethernet". When the 10 Mb standard came into being, it was then referred to as "The Experimental Ethernet". If you want to be *really* pedantic, you could refer to it as the "2.94 MHz Ethernet" --- but that would be silly. If you'd like to see how Aloha

Re: Ethernet names...

Grant - Occasional vague references to “I”, when Ethernet II was used (as I remember). I assumed the reference was for initial 3 Mbps work at PARC. Gateway Communications started in Irvine, CA (1981?) offering G/Net (~double the 3 Mbps), I remember installing their demonstration system (1982 or 1
