This is wonderful. I have a bunch of 5250-type terminals left over from IBM S/38 and AS/400 systems and I’ve been wanting to find a way of using them as VT-100 devices as TTYs for use with Linux & cetera since forever.
Is there any chance that this might come next?
- rbanffy 6y agoShouldn't be impossible - they are somewhat similar to 3270's. Unfortunately, there isn't a Hercules for the AS/400. Someone would need to create it.
- qubex 6y agoFrankly I’d be super-content if I could just use one of my old terminals as a TTY for a Unix machine, even perhaps something as humble as a Raspberry Pi.
- lowobservable 6y agoThe National Semiconductor DP8344 datasheet has some details on the Twinax interface and the 5250 terminal architecture as it was a later IC that supported both 5250 and 3270. I've not read the Twinax part in detail bit skimmed over it; it looks like an extension of the 3270 concept. The topic has come up on Cctalk mailing list (see http://classiccmp.org/pipermail/cctalk/2019-November/051008.html http://classiccmp.org/pipermail/cctalk/2019-November/051008....), and I think Alan was looking to build what you are talking about but was looking for some help reverse-engineering the higher-level protocol.
