I’m in Barnsley which is close to Sheffield. Where in Sheffield is it as I possibly go pick it up really soon if you want.

[cctalk] Re: OT: Ham Radio
Threes this discord server where there is a nice ham community but most of the groups I’ve found are on Facebook. It’s fun to combine both hobbies like I’ve been computer controlling one of my old rigs with a apple 2 and using a C64 in conjunction as a rtty terminal. So many people take joy from seeing what crazy things I do next.

[cctalk] Research machines RM 380
I’ve been restoring a RM380 I picked up not long ago and it’s been good news and bad news. All the cards are in wonderful condition and the case is presentable however the two BASF 6106 floppy drives are highly corroded and probably won’t work again but this isn’t what I’m wondering, the original supply is a little rough but looks tone perfectly restorable with the exception of the key lock been stuck (problem to solve later) and I can get all the parts needed to replace the three filters but it is a 70s linear supply and if my s-100 experience has told me anything they might not be the most reliable. What would you all recommend restoring it and keeping it original or fitting some modern SMPS in its place. It is a low serial number as well (691) but saying I want it to be reliable I’m torn.
[cctalk] Re: SDF had put a PDP-10 on the Internet
I would say it is newly built as the pcb substrate looks nothing like vintage stock. On first glance it’s a impressive achievement reverse engineering the PDP10 cards and then getting it online Jake > On 8 Feb 2023, at 19:55, Sellam Abraham via cctalk > wrote: > > "A new PDP-10 has been put in the INTERNET." > > "New" as in newly-built?

[cctalk] Re: Diablo series 30 or Dec RK03
I got the 8L pretty cheap on eBay a few years back after it had been stripped for parts so it’s been a long restoration project this is why I’m so attached to it. Now that I’ve learnt that for the L I won’t be running anything other than paper tape I’m ok with that as I do like the limitations. I think I’ll stop the search to add mass storage to the 8 and focus 100% on the data general systems which I prefer over Dec as then I don’t have to deal with many many flip chip cards > On 8 Jan 2023, at 19:45, Ethan Dicks via cctalk wrote: > > On Sun, Jan 8, 2023 at 6:40 AM jos via cctalk wrote: >>> On 08.01.23 01:51, jake utley via cctalk wrote: >>> Hello everyone I’m a young collector (18) of 60s and 70s minicomputers and >>> micros.

[cctalk] Re: Diablo series 30 or Dec RK03
The nova a 800/1200 series machine and thank you for mentioning about the 8L drives. I’m hesitant to sell or trade it because it does kind of have sentimental value as the first machine I got and especially since it has such a interesting history (nuclear power plant in France). Since those drives for the 8 are so unobtainable I think I’ll just keep it as the basic system with a teletype and also so I’m not having to swap drives between systems every time I want to use it > On 8 Jan 2023, at 11:40, jos via cctalk wrote: > > On 08.01.23 01:51, jake utley via cctalk wrote: >> Hello everyone I’m a young collector (18) of 60s and 70s minicomputers and >> micros.

[cctalk] Diablo series 30 or Dec RK03
Hello everyone I’m a young collector (18) of 60s and 70s minicomputers and micros. I have been restoring a PDP-8L and would love to find ether a Diablo series 30 or Dec RK03 removable cartridge drive to go with this system. I am in the uk South Yorkshire to be precise and would love any leads anyone could provide on where I could find one would very much appreciated. If nobody know where one of these drives can be located any means of mass storage for a pdp 8L and data general nova system will be appreciated since I want to move my collection forward and have the systems set up with full period setups. Thanks very much in advance. Jake
