16700A internals w/ SCSI2SD v3.0 installed
See my fan upgrade post here on quieting those noisy fans.
See my DIY logic analyzer cart here.
Here’s a couple closeups of the SCSI2SD in action:
HP 16700A boot times and optimization
I’ve been playing with my HP 16700A Logic Analyzer and looking at boot times. Originally the HP 16700A came with an internal SCSI drive, which was still functioning after 15 or 16 years. This SCSI drive was a 4GB...
On building an A500++
Commodore Amiga 500 Plus In the 1980s, Commodore made a newer version of their very popular Amiga 500, called the Amiga 500 Plus. It added a few things, namely newer versions of Kickstart and Workbench — both 2...
Expansion Systems DataFlyer Plus 2.1
Way back in about 1992, I finally had enough money (ok, well, enough credit) to finally expand my Commodore Amiga 500 to how I wanted it. I previously had an A501 memory expansion module and an external floppy drive...
Circle of HOPE 2018 presentation on HomeBrew 68K retro-computing
I delivered a presentation at Hackers On Planet Earth in July 2018 in New York City. For a few different reasons, that presentation was cut short. I decided to rerecord the delivery of the presentation and make it...

Fixed point number formats: might use 16.16
So for my fixed point number format for my 3D project, I’ve come up with a few possibilities : I think a 16.16 number format might work for me. This means I’ll represent the whole portion via one 68k word...
3D Wireframe Rotation dreams…
So I’d really like to be able to rotate 3D objects using this computer. There’s some problems though that make it a little harder than normal. The 68000 doesn’t have any integrated Floating Point...
