Hello, thank You that added me to this forum.
As a child we had ZX Spectrum 48 and AY sound DIY interface. Later we DIY Eprom eraser and programmer, switchable EPROM to ZX with Quick Load/Save, plotter and more.
I wrote some modifications to Eprom. One was called OmegaRom - has buld in Z80 monitor over NMI.
Second was MultiROM #1 - was working as Multiface. With NMI can save snaps of memory, instal pokes and more. Now I found them, so I will revive them with guide.
I wrote two games as Spectrum Omega Software:
TEOFIL - I never found it again. If somebody find it so make me happy!
Nu Pogodi - clone of small portable russian device. Is on WOS.
For some games from Magazines I made tape
Screen loaders or own Screen picture (wanted too):
#R.Mike+
Meteory
Lucifer
Now I have a few ZX 48, 128 and Harlequin 128 devices. I am enjoy it with repairing it myself.
New I have Commodore C64 reloaded and installing it with new chips. I have for Commodore retro feelings too.
I am on Facebook in Spectrum 4 everyone and Spectrum 4 ever groups as Michal Polak (NuClear).
I am Czech so I understand a bit “po polski”, but I can not write so. So I am writing in simple English.
Thank You again.
