I would not be enthusiastic about a GK without a case. I have a working GK for sale.. pm me with offers Quote Link to comment Share on other sites More sharing options...

+mizapf Posted February 11, 2022 Share Posted February 11, 2022 If we have dumps, schematics / manuals, I could try to add the Gramulator to MAME. How does it differ from the GK? 2 Quote Link to comment Share on other sites More sharing options...

apersson850 Posted February 11, 2022 Share Posted February 11, 2022 Maximem could emulate the standard modules at the time. GramKracker can also override the console's GROMs, I've understood. I have both Maximem and GramKracker, but I've not used the GramKracker. It's bulkier when it's in the console. 3 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted February 11, 2022 Share Posted February 11, 2022 Probably the biggest functional difference between the GRAMULATOR and the GRAM Kracker is that the later versions of the GRAMULATOR can also load and run any of the MBX cartridge images. 2 Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted February 11, 2022 Share Posted February 11, 2022 The last DSR (2.0) can indeed do MBX cartridges. I can supply an EPROM to Gramulator owners, if desired. 1 Quote Link to comment Share on other sites More sharing options...
Bill R Sullivan Posted February 11, 2022 Share Posted February 11, 2022 Waiting for one with the case, and wondering if it will block the no/off switch on the beige TI-99/4A? Quote Link to comment Share on other sites More sharing options...
+acadiel Posted February 12, 2022 Author Share Posted February 12, 2022 We can probably shrink the GK by a bit nowadays with higher density SRAM. And put a GAL in there for glue logic instead of all those 74LS chips. This will stay within the bounds of replicating the hardware with period authenticity but allow us to shrink it a bit. We can probably even extend it to use more than 16K ROM carts, although I'm suspecting that the circuitry was a simple flip flop for the two banks, and introducing more than that would mean a bit more circuitry.

However, those of us with a SNUG TI-99/4P system would appreciate 4 banks of ROM (should be write protected RAM) for our TI-99/4A systems, so it will be easier for us to write programs that work on both systems. 1 Quote Link to comment Share on other sites More sharing options...
