MZ-80A RFS Board / MZ-700 tranzputer Board
Posted: Sun Apr 18, 2021 9:38 am
I've got to a point on my projects where I feel other enthusiasts may be able to make use of them, namely:
MZ-80A
Rom Filing System Upgrade board - Adds ROM / RAM storage and SD Card along with an upgraded monitor which runs alongside the original SA-1510 Monitor. I've also updated BASIC SA-1510 and NASCOM Microsoft BASIC to run on the Sharp with SD card access. More info: https://eaw.app/sharpmz-upgrades-rfs/ - I made up 4 of these boards, one is already spoken for so 3 to go.
MZ-700
TranZPUter FPGA upgrade board - Adds 40/80 column colour VGA output (+ other video modes such as the MZ-80B Pixel graphics 640x200), faster CPU upto 24MHz etc. More info: https://eaw.app/sharpmz-700-upgrades-tranzputer-sw/ - I made up 7 of these boards, 4 are already cited in machines so 3 to go.
The price of these boards is not cheap, not because of profit as I'm selling at component cost price to me not including labour etc, just the parts are expensive (ie. the FPGA on the tranzputer, if bought from Mouser Electronics, will set you back circa GBP180 alone - I bought a bankrupt stock so got a batch of them at approx GBP30 each, the PCB's being filled via and small land size also cost me 320 for 10!!!). If these are of interest to anyone please contact me direct as the ones on Ebay are just to test the water to see if I'm flogging a dead horse, ie. no interest in Sharp MZ upgrades or price to build too high!
I can hopefully direct my time to the FPGA Emulator on MiSTer now as a lot of knowledge was gained making the above boards which needs to go into the emulator. I will shortly get an MZ-2000, the missing link on the emulator, giving a good reason to finish it.
