Re: What would you buy?

I'd love to have a Cray of my own - I almost bought a Cray-2 on impulse when one was listed on eBay during the first dotcom bubble. Likewise, any of the big old iron like a System 370, PDP11 or CDC6600 would be amazing but I don't have a temperature controlled environment to run them in, so I'd prob...

Re: Econet X.25 Gateway

I've been keeping an eye out for free Cisco routers with a suitable serial interface/WIC but I've only found ISDN and ADSL 8xx series so far. It's a long-term project :-) I also don't think that these gateways were intended for linking two Econets together. They were intended to allow users on an Ec...

Re: Econet X.25 Gateway

OS ROM is in IC71, ANFS in IC57, TSI in IC37 and a masked ROM that I'm assuming is BASIC in IC62.

Re: Econet X.25 Gateway

Here you go, sorry this has taken so long. One of the more interesting ROMs might be ANFS 4.25 for (supposedly) B/B+ since I thought those could only run up to ANFS 4.18. The MOS ROM looks very different from a normal B+ MOS and has the same credits string at the end as MOS 1.2 for the Model B.

Re: SCSI2SD and FileStore

Did you try it remotely on the L3 server station without the L3 server running? I always thought L3 serv...

Re: Super-simple Econet Clock design

Good job! I did something similar with an Atmega32U2 breakout board with my DIY Econet clock but I used an RS422 differential line driver. The differential PWM from the microcontroller is a really nice touch but I'm wondering whether it has enough power alone to drive a full-length network. Is there...

Re: A440 L4FS Conversion bits and bobs

Unfortunately if you want to keep your costs to a minimum on the Econet side of things, learning to stop hating soldering is likely to be your best option. If you really want to avoid it, you can also pay for Econet 'T' cables from CJE and connect your machines to a clock using those. On the other h...
