My 99/8 computer has a low serial number (#22), it didn't received the Pascal GROM/ROM Kit.
I would like to try this feature. As it will be difficult to find a ROM/GROM Kit, I would like to make my own. No chance for me to produce a GROM, so my idea is to make a hardware GROM simulator that will use EPROM chips and that will use the less component that it is possible to make smallest PCBs. The goal is to install onto the 99/8 motherboard
No need to reinvent the wheel. So, before starting the developpment,I would like to know if someone has already made a GROM simulator that has the abilty to manage 10 GROMs.
Of course, I read many years ago the excelent book of Mike Bunyard about the TI-99 hardware and I was very interested by the GROM simulator that he proposed. But it is only for a 6Kb GROM chip. It could be a start for build my own simulator .
It seems to me that an article about the GROM simulation has been published in the German TI-Revue but I haven't found it.
Do you have any information?
Thanks by advance
