Could have been my bad though so have restarted it.
To be fair though - I dont know about there - but its been extremely hot here.
Maybe the Ent64 is used to the early 80s when you had to run systems in air conditioned rooms.
Its a far cry from that ATM!

Re: Another Egyptian Enterprise 64
Although the custom chips do get a bit toasty, it's only in the 50C range and one of them has a copper plate as a heatsink. Even before I added a few extra heatsinks the machine was stable in 35C temperatures.mrbombermillzy wrote: Fri Aug 14, 2026 1:39 pm To be fair though - I dont know about there - but its been extremely hot here.

Re: Another Egyptian Enterprise 64
New STI 27C512 is in and running my basic program to test.
One thing I found out that I didn't know is that you start off in program 0, but if you type 'edit N' where the N is a number, say 1, then it puts you in a different program space and you have to type 'edit 0' to get back to program 0, but the other programs are maintained in the other program spaces.

Re: Another Egyptian Enterprise 64
Yep, you can have multiple programs, one in each RAM bank, and call them from the other programs using the "chain" command.
From memory, program 0 can be up to 48K in size and the rest up to 32K.

It's a pretty cool feature, shame it wasn't a success, it really seems to be quite forward thinking.stephen_usher wrote: Fri Aug 14, 2026 1:59 pm Yep, you can have multiple programs, one in each RAM bank, and call them from the other programs using the "chain" command.
