Re: Hello from NZ (MTX500 needing resuscitation)

It is perhaps worth mentioning this thread.

If you are not confident in your ability to build one of these yourself, you may be able to get assistance from a local electronics club or maker space.

Re: MEMU (not only) on Pico

Wayland supports X11, so no need to change. If you run XWayland, which I gather is becoming optional / not default on some distributions. If the emulator interfaces with the standard UNIX/Linux serial ports then I guess you don't need GPIO, unless people want to use the emulator as a systems develo...

Re: MEMU (not only) on Pico

I have just pushed a new version of MEMU to my GitHub repository . The main feature of this release is that the configuration dialog offers the option of MFX emulation instead of CFX-II emulation. Given that MFX is the latest & greatest expansion, I thought that was appropriate. CFX-II emulation...

Re: IS there any interest in.... MemoChat

For MemoFest I used Skype as that allows 24h with multiple participants with no charge.

You don't need any installation, you can just use the browser, but that does (I think) require using Edge, at least for the host.

Re: FPGA Firmware Reprogramming

If you have a Raspberry Pi, either a Pico or one of the Linux boards it is actually possible to reprogram the FPGA without Quartus or a USB blaster. It requires: A slightly different programming file (Raw program data, *.rpd). A custom cable. This can be made with a 10-wide DuPont cable with female ...

Re: Only a week until the Retro-Comptuer Festival. Eek!

So it would need a nice 3D printed case.

Re: Only a week until the Retro-Comptuer Festival. Eek!

I can imagine a very small adaptor PCB, which has edge contacts on one side, and a right angle edge plug on the other. The MFX board would then be on the left hand side (and upside down). The mirror image of how the CFX or CFX-II are mounted internally. It would mean that the SD card is the right wa...

Re: Memofest 2023, Where and When?

Wonder if the Tektite font here might help: https://juanitogan.itch.io/p8-programming-fonts , has a cp1252 and a cp437 version, not sure what would be better? I took a quick look at these, but I don't think they help. The MTX requires 8x10 bitmaps, which I don't think are included there. The CP850 ...

Re: Memofest 2023, Where and When?

The CTC and the PIO port were both passing mentions towards the end of the day. Perhaps why I remember them. I have made a lot of use of the CTC over the years: Both of my device programmers make use of the CTC to time the programming pulses. When I was developing my DIY Navtex receiver , the decodi...

Re: Memofest 2023, Where and When?

I hadn't thought about that. My initial interest was adding back some of the capabilities that the CFX-II has (using a Propeller chip).

It may depend on how much memory is required. The MFX has 32KB of video ram.

Do you have a reference for the MSX-2 specification?
