Wanted to build a #RGBtoHDMI (https://github.com/hoglet67/RGBtoHDMI) for my #C128 (80 col mode). But there is a confusing number of different boards: 12 bit, 12bit extender, TTL buffer, ... Which ones do I need?

Philips Computer Monitor 80

Last week I further fine-tuned my CRT repair skills by getting a Philips Computer Monitor 80 (BM7522) running again after almost a decade of inactivity. Some backstory: I found an old Commodore 128D in my mother-in-law’s basement with this original monitor. The whole setup worked perfectly for about 20 minutes, then the monitor started failing. The C128 computer is still going strong, and I’ve […]

La configurazione più comune che si trova è da 16k, montata sul C128 di base e sul C128D. 64k invece sono la configurazione del piu raro CR ("cost reduced") che monta anche una revisione del chip e correzioni ai bug.
Kit di potenziamento della ram si trovano tutt'oggi facilmente su store online, ebay e da altri appassionati.

Il VDC del C128 è una cosa strana. E' un clone Commodore delle schede CGA per PC, con una sua memoria interna che può usare solo il VDC perché la macchina non "la vede" (una "memoria d'ombra"), e che può essere espansa fino a 64k in totale con i kit appropriati. Espanso al limite, il VDC può a risoluzioni folli per questa fascia di macchine, fino a 800x600 monocromatico in certe demo.

The C128 VDC is a funny thing. Is a commodore clone of a CGA pc card, and has its own internal memory, that also the main machine "doesn't see" and is served only by the VDC chip itself.
This memory can also be expanded on any C128 with appropriate kit. With the max expansion it can reach some crazy resolution, up to 800x600 monocrome in some demo.

Se volete provare il progetto, su Github:

... finalmente si può usare il CP/M del 128 in maniera decente? 😱

Mi sembra che Qix sia uno dei rari port per C128 realizzati all'epoca per la macchina in modalità nativa; ed è anche di gran lunga più reattivo di quella 64.
I 2 mhz della macchina qui si fanno sentire.

I wonder if there are demos for C128 that use the build-in Z80 processor, as main or coprocessor. There are some good stuff for the VDC, but I didn't found nothing yet for the Zilog.
I think nobody really tried to use it, or maybe is so rare that I didn't got the chance to find one.

#c128 #commodore #retrocomputing

Mi chiedevo se ci siano demo per C128 che sfruttino il processore Z80, come principale o coprocessore. Ci sono varie demo per il VDC, ma lo Zilog è un pezzo di silicio pressoché dimenticato dentro alla macchina.
Fin'ora non ne ho trovati, che mi fa pensare non ci siano, o siano così rari che non ho ancora avuto l'occasione di vederne.
