Hi,

 

Looking for some old PC equipment if anyone happens to know of anything around:

External 56k modem ( dont ask why lol)

 

Socket A (462) water block of sorts.

 

Case of same of similar design:

 

 

 

 

 

 

 

I know this is incorrect area, but don't have access to buy and sell ( 100 posts). Been a long time since been on forums. But figured this forum is probably one of the better places to look for such things.

 

Thanks

Is a USB modem any good to you? It’s a US Robotics model.

I've got a Lenovo Think Centre case, free to a good home.  I guess it's mid-tower, if that's big enough.  Where are you based?  It would probably need to be picked up.

I disposed of a case (with Pentium III system inside!) almost identical to this about a year ago. Took it to one of the e-waste collections in Pakuranga.

Re: The 56k modem, I have an ATA here I want to try it with. A USB one will be fine for testing, ultimately a serial based one is what im after though.

This will not work, why do you think all so many Alarms / Faxs / Eftpos Machines / Skyboxes with dialup modems have been replaced over the last 5 years as a result of the NEAX shutdowns?

 

Basically, 56K modems don't work over VOIP because they need to have the timing synchronized from a TDM switch (aka NEAX)

 

I would abandon any project you may have involved a 56k modem and look for another way to achieve the same goal

Yes, a "56k" modem relied on the service provider end being an ISDN (64k digital) connected device with digital modems. Over an analogue phone line (which no longer exist, and were emulated for the last 50 years already) the best that could be achieved was 33.6k. Voip lines use encoding and compression that just will not support analogue dial up. Depending on the voip setup you might just be able to get 9.6k to another analogue modem or fax machine if it works at all.

 

Takes me back to my days of installing Cisco AS5300 and Ascend Max 4000 boxes….

Off topic but here is a flashback

 

Working for a dialup ISP in 2001 we upgraded from 33.6k to 56k, local exchange did not support ISDN, so was a 61E RLU-D linked to another exchange into an AS5300 

 

Had to give out a new phone number for our 56k lines, and as we slowly dropped the 33.6k we stepped them to the 56k number

 

Because the new 56k number was not part of same Centrix group as the 33.6k lines we had to pay a per minute to until we eventually dropped the 33.6k lines

 

had to visit a few oldies to change the last few people using the old number 

 

then we had to change our numbers AGAIN to 0867 numbers oh the good old days.......

Are you going to restore retro PCs? Lots of people doing this on YouTube.
