    Dual Pentium III

    I used PFE for a long time when I had to use Windows. Notepad++ fills that niche now on Windows. On Linux, I use vi over ssh sessions, and a mix of the GNOME Text Editor and Sublime Text in the GUI. There's even a Z80 code mode for Sublime.... This is definitely OT at this point. Head over...

    Dual Pentium III

    Indeed. Drifting a bit off topic, but I'm running Debian Linux. On an older generation system with CentOS and an earlier version of Mixbus using JACK I was under 20ms but that was using an Maudio Delta 1010LT. The newer machine, even with it being close to ten times faster than the old...

    Dual Pentium III

    I happen to be a bass player myself... If it were that simple. Latency is a primary concern in multi track production. Multitrack audio production is something that I do professionally using the excellent Harrison Mixbus and Mixbus 32C DAWs. I upgraded from a Core i7-3740 to a Core i7-9750...

    Dual Pentium III

    Yeah, even the most modern multi core multi GB RAM multi terabyte monster GPU system won't let a great writer write any faster or any better; Isaac Azimov used a TRS-80 Model II and it was enough machine for the job. The only true performance gains are in eye candy items and games. I can see...

    Where are all the Model 16B s ?

    Yeah, too big to stuff under a crawlspace ...and at the time no one really thought there would ever be any more interest in them. After all, the 16B with 6MHz 'short' CPU was 'officially' stuck on TRS-XENIX 1.3 (unofficially there PALs to upgrade to run 3.x, which have since been revived even...

    Python

    Python internally compiles to a bytecode that is then run on a bytecode virtual machine. You can precompile python code to a '.pyc' file that is quite a bit smaller than the '.py' source. See https://docs.python.org/3/library/py_compile.html for more information.

    Where are all the Model 16B s ?

    They're all at @pski 's house.....(Just kidding) Seriously, though, most were probably scrapped in the 1990's when they were so unwanted that they couldn't be given away. I had one (serial number was something like 60000002, unsure of the number of zeroes), along with a 6000, the next...

    Tandy 6000 binary-math Basic?

    Yeah, I couldn't remember what was included in TRSDOS-16, it's been quite a while since I booted a copy.

    Tandy 6000 binary-math Basic?

    Here's a link to TRSDOS 16, aka 'Bowling Ball DOS,' on pski's model2archive on GitHub.

    Z280 homebrew board plan

    Nice progress!

    Is there a case to be made for the 386?

    Intel compensated for the multiplexed bus situation with Pentium, a 32-bit CPU with a 64-bit bus. Bus width is why the Pentium Overdrives for the 486 systems underperformed; even at 83MHz, the true 64-bit bus version of the Pentium at lower speed could outperform the 32-bit bus Overdrive...

    Ultimate Pentium Build

    Took a bit longer to dig down to the four NetCache C6100's, but they allow six SDR SDRAM DIMMs to be installed. Registered/buffered ECC, of course. These also include the Socket 370 Terminator in the unused socket. The main board slides out on rack slides; no hard disks inside, just a floppy...

    What do you guys use for reliable benchmarks for modernish CPU's?

    Since I run Linux I use the old Byte benchmarks as a baseline. To get meaningful increases that can actually be felt at the UI the speed needs to be at least double. That's why I've used a rule of three in upgrading for several years; the machine has to be at least three times faster for me to...

    Ultimate Pentium Build

    I once had a dual Pentium HP Netserver LH; pretty close to an ultimate Pentium. I don't remember why I got rid of it; fun machine and lots of room Looked like the photo at https://www.reddit.com/r/retrobattlestations/s/6nuwIjmQ1h

    Ultimate Pentium Build

    I said 4GB is possible, not that 4GB is the max. I would have to double check the specs of the board to see. I think the biggest number of RAM sockets I have seen on any server board is in a NetApp NetCache dual Socket 370. I'll check tomorrow at $dayjob to see how many. Buffered/registered...
