Re: ULA, bus conflicts and the expansion devices
... Congrats for all this deep diving into #Oric's bus and Phi2 sea of troubles! :D Interesting finds indeed! The problem with long cable (>50 cm) is unresolved. The best result was with a 100 cm gold ribbon cable ( literally gold :!: which costs a fortune). My personal solution for all my hardware...

Re: DRAMARDUINO - Dram tester with Arduino

It's the only thing that motivates me to continue to work and release retro hard- and software for free! Keep posting about your #Oric jour...

Re: YM2610
I was wondering how difficult it would be to make an adapter board to replace the AY-3-8912 by a YM2610 :) YM2610 is a BIG beast! The interfacing will be difficult with adapter board in place of AY or as external board on expansion connector. IMO the best way to go is with a FPGA which will emulate...

Re: Sourcing Components
...one for the 5V and the other for the 12V (RS15-5 and RS15-12) Two PSU's will work but why not a single one with Dual Output like RD-35A ? Else the original PSU is not so bad. It has independent 9V output for the Oric and 5V/12V output for the Microdisc. You need only new good wires and maybe new...

Re: Oric.org updates
Great work, @ Symoon ! Randomthought: I wonder if ORIC TREK is a BASIC program and just how difficult it would be to add a glOric view, hmm .. @ ibisum : Your post made me curious and here are some interesting details which (imho) are worth to share: 1. The game page is still available through webar...

Re: Oric-1 Help Needed
...the spaces are unpopulated and I don't see them on the schematic around the RAM ICs, they aren't necessary? Indeed, they are factory unpopulated, may be the reason is mechanical (i.e. better fitting in the case). 20240109_181236.jpg Else, the CAPs are just decoupling ones and I normally replace ...

Re: new (may be not new) Sedoric bug found (all versions)
I don't have a copy of the very first version of SEDORIC and so I cannot determine when this bug was introduced. I would appreciate it if anyone could give me a ".dsk" file for this so that I can carry out research. Here are all available SEDORIC versions on oric.org: click ! (You need to...

Why not DRAMARDUINO?RetroKrazy wrote: ↑Sun Dec 17, 2023 4:50 pmI need a better tester that can check the 4864 to find out which of them is faulty though.
