I wonder if the #c64ultimate could do the trick without extra hardware. The userport is not external ...

Great review and demo of the @futurewas8bit.bsky.social SD2BBC.

I am going to claim full credit for the use of the RJ12 connector on the cable. That worked out really well, and as a bonus, the same cable can plug into a different adapter for the DE-9 userport connector on the BBC Master Compact.

What's especially neat was that this was being downloaded/streamed from CSDB to our C64 via the Wic64 userport WiFi modem that arrived earlier this week.

One of its core out-of-the-box features is a CSDB browser with search-and-run functionality.

The new #commodore #c64 Ultimate still has a userport. It's inside the breadbin. Good to know ...

As a teenager I used to trawl through game and demo memory to see what was in there. But back then I'd reset the C64 with a paper clip on pins 1 and 3 on the userport (I think). This is a little more civilised.

BTW.. If it's a C128D you'll need the USERPORT version to be sure it'll fit.

The only times i did blew a fuse on my C64 where when i messed around on the userport.

Yeah, that will be Gideon's Ultimate64 (the userport adapter is the give away) in a retrofuzion case with Jim Drew's blingboard.

Removes the fun & satisfaction of building one yourself, so more geared to those wanting a short dose of nostalgia, for which the64 already exists at 1/3 the price.

I either boot it from an EasyFlash cartridge with a speedloader ROM and an SD2IEC as drive replacement or plug my Ultimate II+ into the expansion board. The user port hosts a wifi modem for BBS calls.
A C64 Ultimate without an external userport is ultimately not for me 😏

the one thing id like to have used my coins for is technically off site and out of stock, the missing userport.

Da gibt es ausreichend Modem Emulation für den Userport des Orginals.

Hab hier auch einen im Büro stehen, wenn ich denn mal Zeit für ihn hätte.

@64er
Die Downloads in den beiden Screenshots funktionieren. Die Links sind korrekt und zeigen auf die richtigen Files. Aber die Beschriftungen “XXXXXXXXXXXXXXX” sind schon eher eigenartig.

Ich denke, das gehört ins Kapitel Fehlerteufelchen. 🤣
