Re: XC95144XL & XC95288XL obsolete
Most TTL chips aren't being manufactured any more either as the fabs are only interested in high margin chips now. Yeah it's very hard to find TTL chips now. I've been buying tubes of 100 from Mouser for some items to keep stock of what I can. I have been saying for a while that things like the 030...

XC95144XL & XC95288XL obsolete
Just saw in mouser :( Capture.PNG That is pretty much the end of a lot of stuff then. I only use the 144XL on the ST536 / STE536, so I guess for the few which will get built, it will make no odds. But for sure, its the end of a lot of projects for the future :( The 288XL is like £40-£100 now. So I t...

Re: ST536 STE EDITION
@exxos I'd be keen to build up an alpha. One thought: perhaps the IDE header could be on the bottom side if it interferes with the keyboard or anything else. Assuming it doesn't interfere with anything on the motherboard :) It's hard to say how it will all fit until its built up properly and evalua...

Re: Exxos 4MB Ram Upgrade for C070789 strange issue
The switch just connects A9 to the RAM which gives you 4MB. With A9 disconnected from the MMU, it will only see 1MB. BUT the RAM side of A9 gets pulled high by the 10k resistor to stop the RAM address line floating. It's odd a link works but not a wire to a switch. Twisting wires and it having that ...

Re: ST536 STE EDITION
I guess it's the first time I have used the regulator as a jumper link before I make myself chuckle sometimes

Re: ST536 STE EDITION
Almost a year later... I have been trying to do a few tracks here and there to try and keep this project moving along.. Basically all the routing is now done. It *should* fit in the STE, but who the hell knows until its built. STE536.PNG I next need to work on the BOM and CPL files, and finish off t...
