Are there any figures available from HP on how many HP-48SX units have been sold? Or better, is the info gathered from the customer survey `purchase registration' cards available? How many units of the HP-41CV emulator card have been sold? Are there any second-source ROM card manufacturers? What is the cost-quantity/turnaround for HP-manufactured ROM cards? I guess that here voltage regulation isn't as much of an issue. Are the ROM cards some kind of standard PROM modules - can I, with the proper equipment, program the ROM cards myself, or are they manufacturer-masked?

Epson makes the cards for HP and other people who produce software for them. I imagine if you call one fo their reps they'll be able to point you in the right direction. The cards are burned (Overall, they're pretty low volume in comparison to how many, say system ROM's they need to produce), not manufacturer masked.

Regarding contact of HP for sales figures.... I don't specifically know the Corvalis Division's policy, but generally speaking, things like unit sales, etc. are considered company private.

Check Educalc for info on programming your own ROM cards, they offer a service where you send in your RAM card w/ your program, and they send you a ROM card (for $, of course). They also sell a ROM programmer and blank ROM cards.

EEPROMs fade with time, and EPROMs sometimes forget bits which is acceptable only for prototyping. I was primarily asking for masked/fused ROMs, not anything reprogrammable. The cost of $60 (about 10% off at larger quantities) for a 32k card is totally ridiculous and equally unmarketable. Masked ROMs come at a fraction of this, and at much better turnaround times. And, besides, I don't think EduCalc can be trusted to do anything properly. Your mileage may vary. -- Jan Brittenson bson@ai.mit.edu
